The Alliance to Save Energy facilitated a performance contract for the implementation of a water efficiency system known as advanced pressure management on the bulk water supply pipeline into the Sebokeng/Evaton residential area. This area was characterized by excessive water wastage due to leakage. Because of the consumption of large amounts of electricity to pump water to where it is needed, the water saved as a result of implementing this project translates into savings in electricity, which also implies savings in the use of fossil fuels and especially low-grade coal to generate the electricity. This in turn translates into substantial reductions in CO2 emissions.
Shibaura Water Reclamation Center has built Japan’s first reclaimed wastewater treatment facility that use ceramics in filtering reclaimed wastewater treatment. The coming into operation of this facility will make it possible to meet the needs for toilet water in office buildings and water for sprinkling the streets in the Nagatacho-Kasumigaseki and Yashio-East Shinagawa areas.
The Hong Kong Special Administrative Region (HKSAR) Government is implementing Total Water Management (TWM) for the sustainable use of water resources. The TWM programme aims to manage the demand and supply in an integrated, multi-sectoral and sustainable manner. One of the key demand management initiatives of the TWM programme is the promotion of the use of water saving devices. The Government will take a lead to install water-saving devices in its buildings as far as practicable. In this connection, the Water Supplies Department of the HKSAR Government is implementing minor works projects for retrofitting plumbing appurtenance with water saving devices in Government buildings and schools.
