Emergency Sea Outfall

  • Only treated sewage effluent might be discharged in cases when TSE production is higher than TSE demand.
  • The ESO from the Stage 1 Plant to the sea originates near the Northeastern corner of the plant area in a straight line towards the sea where it will be extended for about 2 km into the sea.
  • The ESO will lead first through an open area, then cross the E40 road, then again lead through an open area parallel to a local road and, just before the shore line, cross a fenced plot which is owned by the State of Kuwait
  • The total length of the ESO is approximately 3.5 km with an additional 2 km pipeline leading into the sea.
  • Construction method: onshore — open cut; offshore - microtunneling

Wastewater Transmission System \ Design Build Operate

DBO RESERVOIR NETWORK

Egailah Waste Water Pumping Station, Egailah Additional & OGAL F pumping station

  • Egailah Waste Water Pumping Station (WWPS) was commissioned in the year 2011 and delivers wastewater with a current hydraulic capacity of up to 2.8 m3/s to the existing Riqqa WWTP.
  • The hydraulic capacity of Egailah WWPS shall be increased from 2.8 m3/s to 8.3 m3/s.
  • All upgrade measures shall be implemented without any interruption of the operation of the Egailah WWPS.
  • New substation (132/11 kv) to deliver sufficient power for the upgraded Egailah WWPS.

DATA Monitoring Center (DMC)

Signals from all stations will be connected and transferred to new Data Monitoring Center

The signals will be transferred via new optical cable.

Connected stations are :

WWPS Egailah WWPS Sabah Al Ahmed
WWTP Umm Al Hayman TSE Reservoirs
TSE Secondary Reservoirs Pipe chambers

DMC

  • Located at existing WWTP Riqqa
  • Office space for 200 MPW employees
  • Two laboratories completely furnished and equipped for use of the Project Company and the Buyer to carry out the TSE analysis
