Description of Khalda reservoir (Current System VS Proposed System) Description of the existing system related to the tower side:

Available information regarding the tower at Khalda site and the pumping station are as per the following:

Existing Ductile Iron pipe of 200mm diameter is extended from the main reservoir as a suction pipe line to the existing pumps that feed the elevated tower, existing pumps, Qty:3, (with capacity 70m3/hr. @ 36m head Qty:2 ,and pump with capacity 150m3/hr. @ 36m Qty:1).

Diameter of Suction pipes and valves for each pump is 200mm and the diameter of discharge pipe for each pumps also 200mm, these pumps are feeding the elevated tower through a 200mm pipe extended all the way up against the wall.

The overflow pipe is 300mm diameter and a 100mm washout pipe is connected to it.

A discharge pipe line of 200mm reduced to 150mm, is extended from the elevated tower to the ground level at the flow meter section and then the pipe is enlarged to diameter 200mm connected directly to the main pipe 400mm which supplied the network.

Description of the required Proposed system:

The contractor shall be responsible for the following items and it shall be included within his price of the required works:

The proposed system is to install new three pumps (two on duty and one standby) Capacity shall be 275m3/hr. @ 50m head for each one, connected directly to the network pipe line to achieve capacity of 550m3/h.

The contractor shall inspect, design, construct, supply, install, test and commission pumps with its valves, suction pipe, discharge pipe, electrical panel, electrical cables, control cables, pumps
