Lake Ludas was classified as a RAMSAR site in 1977 and Lake Palic is a Nature Park and part of the Kamaras Landscape Protection Area. Both are shallow Pannonian lakes and home of a large number of bird species. Lake Palic was also a recreational centre in former times till the environmental and biodiversity degradation took place. Both lakes are hypertrophic resulting in blue algae blossoming, frequent fish kill and bad odours. Reducing the phosphorus discharge to the lakes was identified as one priority issue for improving the water quality, since the effluent of the Subotica wastewater treatment plant (WWTP) constitutes the main lake inflow. Another issue is that wastewater from village Palic is discharged untreated. Establishing a buffer zone of bushes and trees between agricultural land and the lakes shall reduce diffuse nitrogen and phosphorus release to the lake and reduce wind erosion. Overpopulation of the crucian carp contributes to water pollution and requires biomanipulation interventions. For addressing the above, the Biodiversity Programme was developed including five investment components i) improvement of the WWTP effluent, ii) expansion of Palic sewerage network and iii) pumping the collected wastewater to the Subotica WWTP, iv) establishment of a buffer zone with bicycle track, visitor view points and procurement of buffer zone maintenance equipment for the Public Enterprise (PE) Palic-Ludas and v) biomanipulation for Lake Palic which includes reduction of the Prussian carp population and introduction of predator fish. The investment programme is supported by three Accompanying Measures i) technical assistance (TA) to the PUC Subotica Waterworks, ii) TA to PE Palic-Ludas and iii) TA to the City of Subotica.

In December 2012 the cyclone Evan damaged seriously 3 of the 5 SHPPs, which should be rehabilitated urgently.
ADB has agreed to assist the GoS in both endeavours. The JV of P&P and STR have been awarded from ADB to perform the Project preparatory technical Assistance (PPTA). The main components of this PPTA are: due diligence on 7 existing feasibility studies for new SHPP projects (comprising technical, financial, economic, social & environmental issues), rehabilitation schedule and investment plan for the power transmission and distribution network, tender assistance for the rehabilitation works of the damaged SHPPs, concept design for a seasonal storage dam project, procurement strategy, capacity strengthening programme (operation, maintenance, trainings).
The project comprises the technical supervision of the works for rehabilitation and modification of the municipal wastewater treatment plant of the city of Ivano-Frankivsk with a population of some 250,000. Technical supervision includes the review and approval of the Detailed and Working Design (Stage R design according to Ukraine legislation) and the actual supervision of the physical works at the WWTP to ensure timely and satisfactory completion of the works and compliance with the signed works contracts as well as with Ukrainian law and regulations.
Hydrology is a key driver for the annual energy yield of hydropower plants (HPP) and since hydrology is quite variable, it poses a risk to such investments. It is in turn very sensitive to climatic conditions and consequently to climate change. Small and medium HPPs are particularly exposed to climate risks i.e. climate change and climate variability.
The study aims at better understanding the influence of these factors on small/medium hydropower plants, the risk on such investments and degree and type of uncertainty and their effect on the banks project finances and decision-making.
The study carries out an analysis of such risks in South-east Europe, Turkey and the Caucasus, using a river basin approach for a number of selected major river basins. The analysis shall lead to a methodology providing the bank with recommendations to assist decision-making on future small and medium hydropower investments.

P&P were engaged by an Austrian private investor to prepare a feasibility study, concept design and environmental impact assessment study for a 225 MW pumped storage hydropower plant. All main plant components were designed in an underground cavern so as to minimise environmental impacts.
Batumi, with a population of 123,000, is the capital of the Autonomous Republic of Adjara and situated in the south-east of Georgia. The existing water supply situation in the town was unsatisfactory, with per capita production rates of 900l/c,d necessary to cover the demand including losses. The existing sewer system was also in poor condition and a source of serious contamination when the streets were flooded. This occured regularly because the storm water system could not cope with the high precipitation rates and was characterised by many false connections. Waste Water Treatment was no longer existent, causing further contamination of the already endangered Black Sea.
Following a feasibility study on the rehabilitation of communal infrastructure conducted in 2005-2006, rehabilitation was scheduled to be implemented in 3 Phases.
In Phase I the water supply and sewer system are being rehabilitated, which in fact means that most of the existing systems require replacement. A new water reservoir of 10,000m3 is also being constructed. Raw water treatment plants are being rehabilitated, including the construction of new intakes, new flow limitation devices and new filter units. Two new waste water pumping stations are also being rehabilitated, including the complete exchange of the M&E equipment.
The beneficiary of the Project is the Municipality of Cantemir (6,000 PE) together with the Municipality owned Water Utility “APA Canal”.
Cantemir WSS, which is based on surface water extraction from the nearby River Pruth, as well as its sewer system and treatment facilities, were designed and constructed for the fruit and vegetable processing factory which used to dominate the city until 1994, when production stopped. The system was constructed between 1963 and 1965, has not been rehabilitated or repaired since, and is therefore in a pitiful state. Since it was designed mainly for industrial needs, many components are highly over dimensioned for its present requirements, resulting in extremely inefficient operation of mechanical and electrical equipment.
In the frame of the project the following project components are being financed:
Pre-feasibility and feasibility study for Langerica SHPP and assistance in obtaining concession permits.
Pre-feasibility study on hydro-power potential in the area of Qarrishta – Letmi.
The project comprises the supervision and coordination of the first 2 works contracts within the World Bank financed Nura river clean-up Project, i.e. the construction and operation of the Apan landfill, the demolition and clean-up of the Karbide factory and adjacent sites and the clean-up of the Nura river and Zhaur swamp.
The former Karbide factory, origin of the mercury contamination in the Nura river valley, is being demolished, with adjacent areas partly cleaned-up or contained. In and alongside the Nura river more than 2 million cubic meter of contaminated material must be removed. River sediment is being excavated by hydraulic dredge and material from river banks and flood plains using excavators. Transfer stations are used to prevent the spread of contamination during transport works.
A hazardous waste landfill is also being constructed near to Temirtau where all contaminated material shall be disposed in two different hazardous waste classes. 24 hours operation is required for all transport works and the landfill to allow implementation of the works within the scheduled 4 year period.
The entire works implementation is based on strict H&S requirements and a strict black – white zone concept featuring special sluices for personnel and equipment is enforced on all construction sites. Parallel environmental monitoring has to be performed by the Contractors under the supervision of the Engineer.
Construction supervision according to FIDIC conditions of contract (Red Book) featuring:
Development and realization of a rehabilitation concept for the SHPP Imst, which consisted of 4 small units along the Pigerbach river, including application for the revised water right permits and limnological impact assessment.
The rehabilitation concept consisted of the rehabilitation of the first upper unit and an improvement of the existing design, with the replacement of the three lower units with one new unit.
In the upper unit the three existing Francis Turbines were improved, as well as the intake structure, the headrace channel and the surge tank. A new steel frame storage and maintenance building was constructed alongside the upper unit, and a new bypass installed so that the upper unit could be shut down. The tailwater channel of the upper unit was also newly built, using precast concrete components.
For the new lower unit, a 2000m long penstock of GRP diameter 1800 (50% of the distance) and diameter 1600 (50% of the distance) was intstalled. This replaced an existing open channel.
The Imst small hydro power plant originally consisted of four small hydro power plants, arranged as one main upper stage and three lower stages. It was operated by an adjacent textile company, the former Textilverarbeitungs- und Vertriebs GmbH.
For the operation of the hydro power plant water was taken from the Pigerbach stream and after the final stage the water was discharged through a tunnel directly into the River Inn.
Following the closure of the textile company, the power plants were bought by the company WEB Windenergie AG, who contracted Posch & Partners to design and supervise the rehabilitation and optimization of the plants. The main upper stage has now been rehabilitated and the three lower stages have been replaced by a single new small hydro power plant.
The upper stage was completely rehabilitated, which mainly comprised concrete repair works at the weir, the water intake and the head race channel, the electrical mechanization of all the existing gates and the full automation of the existing rack cleaner.
A new by-pass was also constructed for the upper stage to facilitate maintenance works and additional storage space was created by the construction of a new storehouse besides the existing plant.
Additional works included the installation of an automatic water level turbine control system and renewal of the energy supply and switchgear. The side walls of the stream channel behind the power house were also raised. Following the rehabilitation works the power production was enhanced and the maximum turbine power of the upper stage is 512 kW.
The automatic turbine control system for the upper stage was supplied by Andritz AG and the automatic turbine control system for the lower stage was supplied by Siemens AG. A challenge for our electrical engineers was the installing of a network between the upper- and lower stage so that automatic control was possible.
The existing water intake of the upper stage, which was built in 1912, also acts as the water intake for the lower stage. This was redesigned to ensure a (dynamic) residual flow is maintained in the stream below the water intake and a fish ladder was installed.
A base amount of 160 l/s flows through the new installed fish ladder. The discharge of the remaining base amount, which is 340 l/s during the months of May to July, flows over a newly installed roller gate. The required dynamic residual flow (15% of the water allocation) is achieved through a hydraulically controlled flushing gate at the weir. The determination of the river water flow is derived from a newly constructed residual water discharge measurement station below the surge tank and an IDM-measurement in the penstock below the surge tank. The hydraulically controlled flushing gate is operated via the PLC system installed in the power house.
The retention water level elevation is at 736.2 m.a.s.l. The consensus water amount of 5 m³/s for the existing upper stage is unchanged. The unlimited water right already conferred was not affected and remains as per the original approved form.
At the power house of the upper stage a by-pass was constructed so that in case of maintenance works on the turbines the water flows through the by-pass to the lower stage. In the power house there are three Francis turbines installed (Andritz AG, 1951). These were completely refurbished, including replacement of the guide vanes, sandblasting and repainting of the entire housing and restoration of the vane regulation.
The tailrace channel of the upper stage has a length of about 176 m, which was originally constructed as a natural, open channel. This tailrace channel was rebuilt with prefabricated concrete elements and a building at the reversal gate on the spillway was also newly constructed. This arrangement provides increased protection from floods and also permits the entire water flow to be discharged into the Pigerbach for maintenance work on the lower stage.
For the lower stage the consensus water of 2.5 m³/s (consensus of the former small hydro power plants 2, 3 and 4) was increased to 5.0 m³/s.
The water from the upper stage flows over a height of about 13 m through an 850 m long headrace to the newly constructed lower stage. (About 1595 m total length, including the upper stage) Below the lower stage water is discharged through the existing tunnel directly into the Inn.
The headrace of the lower stage consists of an existing inverted siphon under the Pigerbach, a 72 m long existing tunnel under the so-called Brennbichl and an approximately 780 m long newly constructed penstock made of fiberglass.
Before the new inverted siphon two closing gates were installed that permit the discharge of the entire water flow via the reversal gate into the Pigerbach so as to allow maintenance work on the lower unit.
The penstock is DN1800 between the end of the tunnel and the hotel Neuner and it follows over a length of 368 m the existing headrace channel (former lower stages 2 and 3). Under the hotel Neuner the penstock was installed as an inliner in an existing steel pipe DN 2200.
The penstock route between the hotel Neuner and the new powerhouse follows for a length of 366 m the existing headrace (former lower stage 4). This penstock section was constructed with GRP pipes, DN 1600. Due to the new design level of the penstock the base of the existing channel had to be removed at certain sections.
Since the existing inverted siphon is an insurmountable obstacle (smooth surface, drop height) fish could not pass this section. For this reason the existing disused by-pass channel was adapted to create a fish pass for this section.
The new power house was built at the same location as the former powerhouse of stage 4, within the municipality of the town of Imst. The exterior dimensions of the powerhouse are 13 x 10 m with a maximum height of 7 m. The shape of the roof of the powerhouse is designed in a waveform, symbolizing the energy of the water. The machine sets are 9 meters below ground level, which was necessary so as to make a connection to the existing underground discharge tunnel that leads to the River Inn. Under the current Danger Zone Plan for the Pigerbach stream the power house is located entirely within the yellow danger zone. The Pigerbach can dissipate in this section a water amount of 50 - 60 m³. In a one hundred-year flood event, which would correspond according to the hazard mapping of 120 m³/s, widespread flooding would be expected in this area. For this reason the ground level was raised around the power house and the entire engine house was also designed so that no hazard is created by groundwater or flood events.
During the construction period the dewatering of the excavation for the lower stage was very difficult due to the high groundwater level resulting from the proximity of the Pigerbach and the River Inn. Evidence for the fact that the entire project is in an area vulnerable to flooding is also substantiated by flood events in the years 2001 and 2005.
The powerhouse contains not only the turbine room, but also space for the switchgear and transformer, a workshop / storage room, a rest room for staff, a kitchen, a wash area and space for maintenance works in the turbine room. There is also a small museum which is used to exhibit the old power plant equipment of the former three lower stages.
The electromechanical equipment of the newly constructed lower stage consists of a Kaplan bulb turbine at 712.40 m.a.s.l. (turbine shaft) and a three-phase synchronous generator (rated output ~ 700 kVA). The turbine was developed by Kössler, the generator was supplied from the company Hitzinger and the control system comes from the Siemens AG.
Discharge water flows through the existing tunnel from the former lower stage 3 (Length 348 m, constructed in 1918) directly into the Inn. The tunnel ends at a level of 709.5 m.a.s.l.
In front of the tunnel a new stilling basin was built with a ventilation shaft. This ventilation shaft also allows access to the tunnel from above.

The Autonomous Republic of Adjara is located in the southwest of Georgia and has been politically and economically isolated since the early nineties. This has led to a sever deterioration of water and wastewater infrastructure and to weak local institutions.
The project objective was to assist the Government of Adjara in the development of a coherent and comprehensive long-term concept for reforms of the water sector. As part of this, the developments and major deficits of the water sector were identified and the involved stakeholders were supported in defining necessary and reasonable reform steps.
The project aimed at identifying and formulating bankable projects in the sectors of water supply, sewerage, wastewater treatment and flood protection. Projects had to be technically, financially and economically feasibly and must be socially affordable to the final beneficiaries. The majority were also designed in a way that they are also eligible for co-financing by EU funds, like ISPA, IPA and others.
The project includes the development of a tariff model which features the calculation of fully cost covering tariffs, socially affordable tariffs for household customers, the calculation of the financing gap in compliance with the EU CBA-guidelines and financial and economic analyses.
Firstly, the project aims at the controlled treatment of the wastewater emerging from the Jasenovo hospital.

Secondly, a feasibility study concerning the water supply of the municipality of Čaška was part of the project. A detailed assessment of the existing situation was undertaken. The findings were used to define the optimum solution taking water quality, security of supply and economical aspects into account.
The irrigated land in Kazakhstan has reduced in area by about a half compared to the times of the Former Soviet Union period. A law on rural consumer cooperatives of water users was adopted in April 2003 and a new water law was approved in July 2004, permitting the foundation of water user groups. The project aimed at supporting the country to put these laws into practice in the existing water user cooperatives by introducing water use fees and puttling in place international best practice for their organisation and management.
The aim of the project is the completion of the partly constructed Yntymak (Intumak) reservoir at the Nura river in Central Kazakhstan. Construction of the dam was started in the 1980s but spillway and ancillary village protection dams were never completed. The reservoir acted as pollution trap as mercury contaminated sediments settled in the reservoir. A dam safety study revealed unsatisfactory condition of the main dam.
The dam must be rehabilitated, the missing reservoir structures as the spillway and the village protection dams must be constructed in order to gain from an operational water reservoir for the future water supply to Astana and for the Korgalzhyn nature reserve.
The aim of the project is the review of feasibility studies of water supply, waste water and solid waste projects in Turkey from an economic, technical, and environmental standpoint.

The foreseen investment for this project phase was limited to the construction of a mechanical treatment train and to primary sludge treatment facilities.
Water supply and wastewater services in the country are currently managed by over 30 water utilities. The utilities are strongly engineering oriented. The national water sector concept foresees the consolidation of them to about 4 utilities which shall become be financially viable. There is need to develop sound customer oriented policies and programs which respond to the needs of customers, particularly women who are the main water user and deal primarily with the utilities.
The project aims as finalising the consolidation process, strengthen the utilities capacity in billing and collection activities, decrease of non-revenue water, establish contacts with utilities in the EU, establish cooperation with the water & wastewater regulatory office and improve customer services by considering the gender aspect.
Batumi, the fourth largest city in Georgia, is the capital of the autonomous Republic of Adjara. The water supply situation was unsatisfactory with per capita production rates of 900l/c,d, necessary to cover the demand including losses. The existing sewer system was also in poor condition and a source of serious contamination during regular flooding events.
The aim of the feasibility study was to ensure that the envisaged investments were directed towards the most urgent issues and used most efficiently. The study included first an assessment phase regarding water supply services, wastewater disposal, economic and institutional performance of the water utility, and economic capacity, as well as the needs on the side of consumers. To assess the socio-economic base parameters of the consumers, a household survey was conducted. The water supply system was assessed by hydraulic modelling, with leak detection and flow and pressure measurement campaigns carried out. The sewer system was assessed by manhole inspection and CCTV.
The aim of the project was the development of operational guidelines for the Yntumak reservoir. The reservoir is located on the Nura river in Central Kazakhstan downstream of the Temirtau - Karaganda industrial area. Since its construction the reservoir had acted as a sediment trap for pollution being transported by the Nura River. Mercury contamination in particular had accumulated in the reservoir and the reservoir prevented most of the polluted sediments from drifting further downstream, so limiting the extent of the contamination.
Focus was therefore drawn on the existing mercury contamination in the reservoir, i.e in the bottom sediments in relation to sediment management. As the dam structure was not yet finished, recommendations on the future design of the dam, outlet and spillway structure were also made, so as to guarantee minimal impact on the stakeholders and the environment.

Technical assistance was provided to the Project Management Unit of GAP by developing a strategy for wastewater management in the area, including studies on alternative waste water treatments such as land treatment. An assessment study for solid waste management was carried out including the formulation of 6 projects for sanitary land fills and transfer stations. Also, design / tendering of landfill sites and transfer stations, design of water treatment facilities, design of non-revenue water reduction programme for several towns and rehabilitation and upgrading of 30 drinking water systems have been developed.
Project identification, project formulation and project appraisal for the assistance programme of the Government of Austria to several towns in Bosnia-Herzegovina in the sectors of water supply, waste water and solid waste for the fiscal years 1998 to 2000.
Rehabilitation of water supply systems for 6 selected towns due to war damages. Evaluation of the demand for repair of the pipe network, pumping stations and treatment plants, delivery of tools. Preparation of tender documents and cost estimation.
The Regional Water Company (Veika) of Kjustendil was responsible for water supply, sewerage and waste water treatment for eight municipalities in the region. The population supplied was over 130,000.
The previously fully state owned water company had been recently restructured. To assist the young company in the planning of investments and future operations, a feasibility study was carried out under the supervision of The World Bank and the PMU of the Ministry of Regional Development and Construction in Sofia. Main objectives were to assess the present status of the water supply and waste water facilities as well as the organisation of Veika, on the basis of this to formulate a three year investment programme and to improve the water and waste water facilities and the efficiency of Veika.
The Deriner Dam and Hydropower Project was constructed on the Coruh River in the north-eastern part of Turkey and consisted of a 260m high arch dam (3rd highest in the world at the time) and a hydropower plant with 600 MW installed capacity.
Technical assistance in the preparation and formulation of the National Environmental Action Plan (NEAP) and Local EAPs for the Republic of Kazakhstan. Work carried out included data collection and data evaluation, the identification and assessment of hot spots, evaluation of environmental impacts and possible solutions for remediation and clean-up projects.
In addition, an assessment of the institutional situation was carried out, assistance was provided in the priority setting process, mitigation projects were evaluated economically, and an action plan was prepared. Also, the NEAP prepared by the local experts was reviewed. Final results were presented at senior Government level workshops.
The World Bank provided support to the country’s rural water supply sector by paying utmost attention to community based integration and approachs. This included wells equipped with hand pumps and other simple isolated water supply systems that were constructed solely by community participation. For water supply systems of small towns, simple centralized systems were introduced. To enable the involvement of local contractors, who lacked the capacity to deal with complicated and complex contracts, a standard contract document was required together with standard specifications and corresponding drawings.
Posch & Partners were commissioned to prepare such documents, covering a wide variety of technical solutions and split up into different volumes, which could be put together into a single document suitable for each particular case.
GTZ provided assistance to the Small Hydropower Development Organization (SHYDO) for the preparation of feasibility studies and the construction of one small hydropower plant as a pilot project, a 4 MW plant at Reshun in the Citral Region.
P&P supplied technical assistance by providing the Team Leader for Civil Engineering, with the main responsibility of pushing the implementation of the pilot project and securing technical assistance and construction management for the local companies involved. The Team Leader was also actively engaged in the preparation of feasibility studies for a number of small to large dimensioned hydropower plants in the country.
Provided civil engineering Team Leader for:

The Potsdamer Hütte is a mountain shelter with full board facilities in the Stubaier Alps in Tyrol at an elevation of 2012 m.a.s.l. The present water sources do not comply with the regulations concerning the quality as well as the quantity. Also the civil structures at the spring have to be rehabilitated.
A hydrological study was carried out as well as bacteriological investigations on the water and proposals for improvement determined.
Also a precipitation run-off model will be made to establish possible hydro power potential to supply the mountain shelter with electric energy.
The main wastewater treatment plant of Darmstadt could not cope any more with the new legal requirements and the present wastewater organisation. Consequently, complete rehabilitation of the old plant and augmentation to a capacity of 300,000 people equivalent was commenced in 1992, capable of eliminating Carbon, Nitrogen and Phosphorus. Due to the excellent results previously obtained at the Eberstadt plant, the Phostrip-process was also selected for Phosphorous elimination at Darmstadt.
35 water supply schemes (Area A and Area B) were rehabilitated and extended under this World Bank project. The schemes needed urgent replacement of electro-mechanical equipment and rehabilitation of civil structures. Comprehensive planning studies were carried out for all 20 water works, including groundwater studies and hydro-geological investigations, to determine the long run least cost rehabilitation solutions. This was followed by detailed design of all systems, preparation of tender documents and construction supervision. Construction works were co-financed by three different donors. This required special inputs and flexibility, to satisfy each of them regarding their special financing and administrative conditions.
A pre-feasibility study was carried out for the three possible sites and the Rangjung alternative in East Bhutan was selected. For the feasibility study and the detailed design all available hydrological data was collected, evaluated and computerized. The results are based on extensive topographical, hydrological and geological survey and comprise power generation, transmission and distribution. The final design included static calculations of civil and hydro steel works. Tender documents were prepared. The 1100 kW plant with a head of170 m included a Tyrolean weir intake with settlement basin and a power conduit partly within a tunnel.
The Himalayan villages Namche Bazar, Khunde and Khumjung, situated about 3.500 - 3.900 m.a.s.l., had became a tourist centre, with the associated benefits and impacts. For health reasons, the provision of drinking water to the local population and for tourists had become an urgent requirement, as the existing supply was unsatisfactory. In addition to improving the drinking water supply, new sewerage and waste water treatment facilities were also constructed.
The electrification of Namche Bazar and the adjacent villages Khunde, Khumjung and Thamo was of fundamental importance for the survival and development of the whole region, as no other form of energy was available in the future due to deforestation.
The plant, with a capacity of 600 kW and a net head of 210 m, was located at an elevation of 4000 m.a.s.l. and was not accessible by road (140 km distance to the next road connection).
The project not only covered the energy production; it started at the spring in the glacier region and ended at the kitchen stoves and heating systems in the Sherpa houses. New concepts for efficient energy utilization were developed, with also the necessary infrastructures to operate, maintain, repair and expand the system in the future. The planning and implementation of drinking water, biological waste water treatment and waste disposal was also included in this project.
