Project Description
Scope Of Work
LSPB project for upgrading of the drinking water production facilities at Dhahran and Dammam. Dhahran Drinking Water Plant (DWP) will produce an average flow of 1,100 gpm and it is proposed to install three (3) Reverse Osmosis (RO) skids of spiral wound membranes, three (3) feed pumps, three (3) product pumps, three (3) degasifiers and a substation building to accommodate electrical equipment.
At Dammam Office Building complex (DOB), two (2) RO skids of spiral wound membranes will be installed, to produce an average flow of 90 gpm. The existing RO skids at both plants will be dismantled and disposed. Also, the contract includes construction of an 18-inch dia. 3,760 meter transmission pipeline (RTR) from the new drilled wells in Dhahran Hills to Dhahran DWP.
