The WTP complex covers an approximately 380-acre land area inclusive of a future expansion plot. The development consists of 2 building types; Process-Buildings and Non-Process Buildings.  The Process-buildings involved several blocks arranged in such a way that allows raw water intake to undergo an ultrafiltration process through a filter membrane.  The Non-process buildings are the Administration & Control Centre, staff quarters, community hall, surau, and other amenities.  These 2 building types are separated into 2 different zones.  The Administration & Control Centre building is designed as a hallmark and an epitome center of excellence for the role played by Air Selangor in ensuring a crucial supply of water security and sustainability. The building form is inspired by a water-drop logo of Air Selangor which is further translated into a building plan incorporating curvilinear-flowing circulation and dynamic corners.

The  scope of work of this project (stage 1) comprises the design and build of the following:

An intake structure of a 1400 million-liter-a-day (Mld) capacity to draw augmented raw water from the ex-mining ponds at Taman Putra Permai, Puchong;  A 700 Mld of water treatment plant near Tanjung Dua Belas including civil, structural and building, process plant mechanical works, electrical, instrumentation, SCADA, building services and associated external works; 2.4m diameter twin-pipe connecting the Intake structure and the water treatment plant; Two overhead bridges crossing Elite Highway and SKVE Highway.

The site possession of this 35.5-month project will aim to be completed by June 2025.
