Eptisa returns back to Prilep for continuance of the already started story when in 2009-2010 the EU funded project “Technical assistance for preparation of investment project for wastewater collection and treatment in Prilep”, was successfully implemented. This project secured investments in WW and WWTP in Prilep in the amount of around 26Miliion Euro and it was first IPA project from this kind in Republic of Macedonia.

Investments in wastewater were divided in two phases. The first phase for extension and rehabilitation of 23km of sewerage network in Prilep is in finishing phase.

The second phase – Construction works for rehabilitation and extension of sewerage network in Prilep, EuropeAid/134753/IH/SER/MK22 for extension and reconstruction of 44km of sewerage (7Mill investments) will be supervised by EPTISA in accordance with FIDIC Red Book Conditions of Contract for Construction, First Edition 1999. The works will commence in November 2015 and will be financed under the IPA programme.

The overall objective of the project is to improve environmental protection through investments in environmental infrastructure, and create conditions for environment friendly sustainable development, with prevention of surface and underground waters pollution.


The existing drainage network in Prilep was designed in 1973 as a separate system with separate foul and storm drainage. Construction of the drainage and foul sewerage networks was carried out in the 1970’s and 1980’s and covers approximately 80% of the town.

There are 17,561 known property connections for domestic, industrial and institutional customers connecting 60,105 out of 75,131 inhabitants to the municipal wastewater system corresponding to service coverage of 80%.

The un-served population amounts around 15,000 inhabitants and is predominantly located in the unsewered districts of the town or is or in the peripheral areas of the town. About 5% of the residents are in areas where central sewerage system connection is not feasible compared to organized collection and discharge of the retained septic sludge from the on-lot utilities.

In addition to the municipal sewer networks, there is a substantial number of makeshift combined sewers in the periphery of the town that were installed by individual householders.  These unregistered sewers are not charted for services and partly not connected to the municipal sewer system.

Between 40 – 60% of the properties have a single connection pipe discharging both domestic wastewater and storm water from roofs and yards to the wastewater sewers.

The entire wastewater of Prilep is discharged untreated through the Main Collector DN 700 into Prilepska River approximately 2 km southwest of the town.

Recognizing these problems with sewerage network in Prilep, the construction of a wastewater treatment plant (WWTP) and modernization of the wastewater system of Prilep have been identified as priority in the environmental sector.

The second phase for rehabilitation and extension of sewage network in Prilep, which is part of this project, has main goal to provide proper conditions for Municipality of Prilep and PCE ˝Vodovod i Kanalizacija˝ Prilep to disconnect all drain pipe in critical areas in the town and to extend network in un-sewer areas which lead to increasing of the connected inhabitancies to the city network.

With respect to the awarded contract, for the next 30 months, EPTISA will act as the Engineer in accordance with FIDIC Conditions of Contract (Red Book) during the extension and rehabilitation of 43 km of the existing sewerage network.

The civil works that will be supervised by a team of engineers from EPTISA comprise:

  • Construction of 43 km of new sewer lines with pipe diameters from DN/ID 250 to DN/ID 400 for extension of the sewer network;
  • Construction of about 1260 sewer manholes;
  • Construction of about 2680 property connections;
  • Reinstatement of roads.

EPTISA will ensure that services for supervision of the construction works are in accordance with all the requirements for quality control, control of design, control of quantities, supervision of the work progress, analyses of expenses as well as work on administrative questions during the construction and the defects liability period.

The assignment has a value of 499,750 Euro and is financed under the IPA programme. The Contracting Authority is Central Financing and Contracting Department, (CFCD) within the Ministry of Finance.
