Water Efficient Building Certification Programme

Certification Programme

Since 2004, businesses, industries, schools and buildings from the non-domestic sector have been encouraged to include water efficient measures in their premises and processes, and to earn their WEB Basic, Silver or Gold Certification. By installing water efficient fittings and adopting the WEB recommended flow rates/flush volumes, they can save about five per cent of their monthly water consumption.
