Project consists of two story blocks for the three main educational levels (KG to Secondary level) along with an auditorium (total site area 12,555m2). Our scope was to do the design of plumbing services for this facility.
The Plumbing services for the project included water supply and distribution, sanitary and storm water disposal systems. These services were designed in accordance with the local and international Codes and Standards.

PLUMBING DESIGN REPORT/SUMMARY - Sample of the Technical Report

Site Water Supply
Water to the site will be obtained by connecting to the existing Municipality water mains. Municipality water will be stored in a combined underground domestic and fire water storage tanks.

Domestic Cold Water
Stored potable water from the combined domestic and fire water storage tank is transferred to the sanitary fixtures by means of water transfer pumps to attain the required pressures at the water outlets which should be maintained to achieve a minimum of 1.0 bar at the hydraulically most remote fitting.

Domestic Hot Water
Domestic hot water for the wet areas are generated locally by using individual type electric water heaters installed above false ceiling. Hot water supply temperature will generally be maintained at 55°C.

Sanitary Sewer Drainage
Sanitary drainage comprise a one-pipe vented gravity system installed with adequate falls discharging eventually to outside the building. External sanitary pipes and manholes convey sewage and wastewater to the existing Municipality main sewer line.
Sewage lifting stations were provided as required to discharge sewage from wet areas which can not be discharged by gravity system.

Storm Water Drainage
Storm water from roofs are drained through roof drains and piped to discharge freely above the ground level along the adjacent roads.

Pump Rooms & Tanks
Complete design of dimensional layouts with sections was provided for all plumbing rooms & tanks in coordination with other services including pipes & pump arrangement and equipment schedules.
