The consultants were appointed to prepare the master plan and feasibility study for the two sewerage and sewage disposal project to serve the ultimate population of 600000 in 2025. Following approval of the study report the consultants' proceeds to prepare the detailed engineering design, specification and contract documents for the system and sewage treatment works.

GHADAK is responsible for only WWTP works and detailed engineering designs and contract documents for mechanical and electrical works. In addition to this,
GHADAK is also responsible for the design of sewerage systems and pumping stations. WWTP was designed to treat a maximum flow of 3m 3/sec.

The system was separated for each side of the city in order to ovoid crossing the river or building a tunnel on River. This designed based on activated sludge [extended aeration type] process, and consist of fine screens, detritus, aeration tanks, final settlement tanks and disinfecting by chlorinating. Sludge treatment effected by heated digestion and drying in beds.

The design and layout of the treatment plant would facilitate future extant ions of the works by divide them in to streams. As the final effluent to be used for irrigation Associated works compromise the main lift and final effluent screw pumping stations, power generation and distributions, administration building, works, laboratory and workshop facilities.

Full document and drawings including the whole design and specification were submitted to water and sewage corporation (WSC).
