Kahramaa awarded this contact to Petroserv to design and construct a new pumping station and associated Pipeline in the Salwa Industrial RPS.
The existing pumping station at Salwa industrial RPS is old and might need to be demolished in near future due to the Operational requirements. Hence it is required to construct a new and independent pumping station at existing Salwa Industrial RPS with many future slots to substitute the existing pumps at old pump house. The new station shall be interconnect with existing Kahramaa distribution network to allow for delivering water to supply the future, existing and under construction distribution networks located within served areas of Salwa industrial RPS.
- The scope of this CONTRACT is to provide detailed design, supply material & equipments, construction, erection, testing, and commissioning of the CONTRACT components as detailed below
- New pump-house and control building along with all necessary civil, mechanical, electrical, control, Fire alarm & protection, and instrumentation works to accommodate/ operate twelve (12) VFD operated pumps with 4 pumps (320 lps @ 75 meters head) at this stage and balance 8 Pumps in future
- Construction of approximately 1500 meters of new 1200mm/900mm/400 Ø rising mains pipelines and associated Valve chambers (17 Nos) inside the new water station and up to interconnection points to existing pipelines.
