TECHNICAL OVERVIEW
The treatment plant project includes installation of pumping equipment (four new 160-kW pumps) where the existing water-intake system is located. The new treatment plant includes construction of 12 plate settlers with four coagulation chambers and 12 flocculation chambers. Also, construction of dosing and storage facilities for reagents (lime and aluminium sulphate), 12 sand filters, and a semi-underground treated-water storage tank with a capacity of 23,000 cubic metres.
The infrastructure will also feature new chlorination equipment in the existing chlorination building, electrical cabinets and wires, automation systems and SCADA applications, six new 500-kW pumps for treated water in the existing pumping facility, two 50-cubic-metre surge-control tanks, interconnection pipes (cast-iron pipes ranging in diameter from 600 to 1,200 millimetres), and drainage networks. Implementation of the new plant and its connection with the existing plant are both integral parts of the contract.
The foundations for all structures will consist of 1,056 piles, 400 x 400 millimetres at the pilehead and 22 metres long. This is the first water-management construction project for VINCI Construction Grands Projets in Cambodia. It is also one of our largest projects calling for the construction of a drinking-water treatment plant.
