Diamond said certification would rate where water comes from‚ how it is used‚ what measures are in place to reduce use of municipal water‚ how much effluent is discharged into the sewerage system and the quality of this effluent
Companies will be awarded points if they:
- Implement measures to reduce their drinking water consumption;
- Make changes to operating systems to reuse greywater; and
- Treat their own wastewater.
Deputy mayor Ian Neilson said Cape Town dam levels fell by 0.3 percentage points to 22.7% in the past week‚ but consumption rose from a record low of 511 million litres a day the previous week to 565 million litres.
“We will continue to monitor the water usage trend to see whether the increase in consumption is a once-off occurrence or whether there is another underlying reason that would need to be addressed‚” he said.
“The city is still required by the national government to reduce water usage to 450 million litres per day in order to stretch the available water supplies through the rest of the year. This equates to a reduction of 45% from normal usage. We are currently hovering at just below a 40% reduction.”
