Brief Presentation of RWC-Prishtina
Before 1961 – Germia natural resources and Wells in Kolevica
1961 – Badovc Lake Reservoir
1979 Batllave Lake Reservoir
Underground Resources Fushe Kosove and Obiliq
1999 – Consolidation of the Company
2007 Regionalization and it becomes as a Joint Stock Company with name Regional Water Company Prishtina
These days RWC-Prishtina supplies somewhere around 40% of Kosovo population connected to these services
RWC-P Services ( Areas )
Regional Water Company Prishtina j.s.c provides services in the
North East and Central Part of Republic of Kosovo

Water Resources in RWC-P
RWC-P has two major Water Treatment Plants
-Albanik – Podujevë, and Badovc
There are 6 objects – facilities that treat underground
water from wells in: Kroni, Kastriot, Shtime, Lipjan,
Podujeva and Drenas.
22 Pump Stations
Water Tanks with V= 70.000 m³
1.200.000 m Primary and Secondary Pipelines
INTERESTING!
RWC-P has in total 120 000 consumers , with
110 000 active and 10 000 passive.

Team and equipment for NRW
NRW Department is located in Head office in Prishtina
Equipments for leak detection and others needed for the group are:
Acoustic Leak Detector
Pipe and Cable Detector
AML, All Material Locator
Ultrasonic Device
Pressure Loggers
Flow and Pressure Logger with GPRS
Ultrasonic Measuring Device for wall thickness of pipes
Mini Water Leak Detector
Noise level and frequency logger
Locator of buried valves – hydrant cone covers
Ground Microphone
Magnetic Key etc
Steps for data collection
Real measures directly on Main Pipes
Measures on site made by
Ultrasonic water meter device
GPRS pressure / flow data logger,
and pressure logger
Steps for data collection
Real measures directly on Main Pipes
First steps taken were, replacing the existing water meter and a gate valve, installing new one and a saddle for
pressure control via pressure logger .
Steps for data collection
Real measures directly on Main Pipes
Second one we are continuing with measures with Ultrasonic water meter device
Steps for data collection
Real measures directly on Main Pipes

Water loss factors
Major water loss factors
Existing Network – Areas with AC pipes ( villages and part of town )
“New” network that has been constructed after year 2000 ( bad quality of
pipe as a material )
Illegal Connections
Leakages inside the multi story buildings
Water meter reading and controlling
Calibration of water meters
Installing pressure reducer valves in different zones
Proposal to improve situation
Detailed analyses for loss factors in areas where we have new network with
HDPE pipes
Develop a leak detection group also in the Unit with right equipment & devices
Replacing existing AC lines and other pipelines with burst problems
Creating new DMA zones
Installing water meters and calibration of existing water meters
Installing Bulk Water Meters
Finding and elimination of illegal connection
Inspection and survey all existing lines
Installing HDPE RC pipes lines
Detailed analyses for efficiency of pumps
