Water Star Rating certification
The City’s updated Water Star Rating certification recognises the integrated water management system, and promotes best practices in water management, conservation and pollution control in every sector.
Star rating system
Under the star rating system, participants that receive one star are certified as compliant with the minimum requirements of relevant water legislation and the City’s
Water By-law (2010) and
Amendment (2018). Participants that are awarded between two and five stars are certified for also implementing different degrees of additional measures to further reduce water consumption and limit water pollution.
Those who achieve five stars are certified as champion innovators that have found unique/extraordinary ways in which to conserve water and limit water pollution, thereby protecting the environment.
What the assessment covers
The certification process includes an assessment step that focuses on how water is managed. The voluntary assessment covers different aspects of water management, namely:
- how effluent is handled (e.g. is it discharged into the sewer system or taken away lawfully for re-use by another entity or for destruction);
- how the water is used on site (e.g. drinking, cooking, bathing/showering, operations/production related activities);
- what measures are in place to reduce municipally-supplied drinking water demand; and
- where the water comes from.
How points are scored
Participants score points if they, for example;
- have put in place measures to reduce municipally-supplied drinking water;
- know how much water is used per location (i.e. metering at point of use);
- promote less of a dependency on the municipal supply by using rainwater/borehole/treated effluent/greywater;
- responsibly discharge effluent or have zero effluent discharge; and
- undertake and can account for regular leak detection and repair, meter auditing and awareness programs.
Did you know?
A Well-run City:The City has also partnered with the National Department of Public Works to reduce consumption at its facilities through the installation of water-saving fittings, reduction in water pressure and a leak detection and repair programme.
Additional resources
Those who manage large facilities in Cape Town should note the significant savings that can be achieved through using the treated effluent the City supplies.
