The Water Efficient Building (WEB) Certification launched in 2004 encourages businesses, industries, schools and buildings from the non-domestic sector to include water efficient measures in their premises and processes. The WEB Certification is also recognised under the Green Mark Certification scheme for buildings. The WEB (Basic) Certification can be obtained by installing water efficient fittings and adopting water efficient flow rates/flush volumes. In general, a certified water efficient building can save about five per cent of their monthly water consumption.
