Project Type Special Assistance For Project Implementation (SAPI), Construction and rehabilitation of Water Treatment Plant (WTP)
Project Title Zletovica Water Use Improvement Project
Location Probistip and Stip, the Zletovica basin, Macedonia
Client Ministry of Agriculture, Forestry and Water Economy, Macedonia / Public Enterprise Hydrosystem Zletovica (PEHZ) /JICA
Project Period 2011 – 2014
UF Membrane at Probistip WTP
Sedimentation Basin at Stip WTP
Problems addressed by the Project
Zletovica, located in the north-eastern region of the Former Yugoslav Republic of Macedonia faced water shortage during summer season.
At Probistip, before the WTP construction, the water system was made up of shallow wells, a reservoir, and chlorine dosage equipment. The pump and piping were antiquated so that frequent failed supplies were caused by the breakage in addition to a shortage of water in summer season. At Stip, before the WTP rehabilitation, tap water was supplied through a WTP using raw water pumped up from shallow wells that made pump operation expensive and the WTP structure was poor since surface concrete had flaked off and the reinforcing bar was exposed.
Thus, Probistip and Stip municipalities were seeking an additional economical, stable, clean and safe water source and the new WTP as well as rehabilitation WTP to treat the Zletovica water.
Project background
The Zletovica Basin Water Utilization Improvement Project, the first Japanese ODA Loan project in Macedonia, began in 2003 to supply raw water to municipalities in the Zletovica river basin, was comprised of four packages: 1) construction of an access road, 2) construction of the multi-purpose Knezevo Dam, 3) construction of two intakes downstream of the Knezevo Dam and transmission pipelines from the intakes to municipalities, and 4) installation of SCADA. The water quality from upper stream of the Zletovica River is clean with the turbidity in Nephelometric Turbidity Unit (NTU) at usually less than 2.
WTP constructions were supposed to be implemented by the local governments within their budgets, however budgets were insufficient. In 2011 construction of the Probistip WTP and rehabilitation of the Stip WTP were included in the JICA ODA loan project upon request from the Macedonian Government. Slovenian Government grants were also applied for the works.
Service Period
Assisting Ministry of Agriculture, Forestry and Water Economy and PEHZ in the construction and rehabilitation of WTPs in terms of administrative and technology matters
Carrying out design review, tender assistance, construction supervision of Construction and rehabilitation of Probistip and Stip WTP
Assisting Probistip municipality and Stip municipality in reaching an agreement to receive Slovenian Funds
Actual Project Works
Probistip WTP (New construction) UF membrane (Population to be supplied: 16,000, Design capacity: 6,480m3/day) Sufficient gravity pressure to the UF filtration from the intake was the element to select the UF system for the
treatment system, which does not require pumps.
Stip WTP (Rehabilitation) Sludge blanket + rapid sand filter (Population to be supplied: 47,200, Design capacity: 43,200m3/day)
