3. Supervision ofWater Supply Systems RehabilitationWorks in 17 (21)Towns of Georgia under WIMP
(Rehabilitation of OzurgetiWater Supply System - EIB/WIMP/W/ICB/12-L1)
 Due to deteriorated conditions of existing City Network and Transmission Main Pipelines, part of City
Network is to be rehabilitated. 3nr of Pump Stations were to be fully rehabilitated and system
modernzied.
 Project included: rehabilitation of 3nr pump stations with installation , including complete civil
rehabilitation works, provision of new pumps (8nr in total ranging from 360m3/h @ H=65.2m ,to
160m3/h @ H=80.4m), associated Steel Pipes, Valves & Fittings, new Pump Motor Control panels,
Building Services, new High Voltage & Low Voltage Switchgear, SCADA System (automatic Pump
Control, Flow Measurement, Chlorine Residual Monitoring) and installation of Chlorine Gas Dosing
Systems.
 Extension of Distribution Network, installation of Distribution Network 5,700m of PE100 Pipe (OD250,
OD200, OD160, OD110, OD90 & OD63), 385m of Steel d219/5mm Pipe, associated 264nr House
Connections & associated 2,000m of PE100 Pipe (OD20) and “sectoring” of Network with 19nrValves.
