Dams supplying Nelson Mandela Bay and Kouga hover at 40% full

According to data released by the Nelson Mandela Bay Municipality on Monday, the average water level in the five dams supplying the Bay and the Kouga Local Municipality, is now down to 40.24% - with Churchill Dam holding roughly just 20 days worth of water. 

From the stats, while the Kouga, Churchill (which has seen the biggest drop) and Impofu dams continued to drain, the smallest dam - the Loerie dam, actually rose by about 10% from 34.93% to 44.75% while the Groendal dam did not change. 

Last month, Nelson Mandela Bay Municipality Executive Mayor, Athol Trollip, said that the last 10% (dead storage) of dam`s water is mostly not useable - hence, technically speaking, the dams have effectively fallen to about 30% full.

The Metro had projected that the total dam storage will be less than 40% by the beginning of May 2017.

Below is the latest figures;

Dam and  Current Capacity

  • Kouga dam: 23.62%
  • Churchill dam: 15.079%
  • Impofu dam: 66.50%
  • Loerie dam: 44.75%
  • Groendal dam: 56.44%
  • Average all: 40.24%

In the event that water levels drop below 40%, the following measures and recommendations will be implemented:

  • The Municipality will introduce Part C of the approved Tariff Schedule for water for all residential and institutional consumers;
  • The Municipality will introduce Part B of the approved Tariff Schedule for water for Commercial and Industrial consumers;
  • All domestic customers using more than 40 Kl/m of water be given a two week notice to fix leaks or reduce water consumption, failing which a water flow meter restrictor device be installed to limit the usage;
  • All current and future borehole users as well as drilling contractors must in terms of the NMBM Water & Sanitation By Law (Clause 83) register at the NMBM (Infrastructure & Engineering Directorate: Water & Sanitation - Water Distribution);
  • Apart from concrete activities, contractors to use recycled water from Fishwater Flats or any other approved wastewater treatment works where disposal facilities exist; and
  • Borehole water from the trial holes must be made available free of charge for non-potable use at the Motherwell Cemetery under strict access conditions.

Trollip said that the volume per user will be as directed by the Executive Director: Infrastructure & Engineering.

He said that the Municipality is currently implementing various emergency schemes and interventions to mitigate the consequences of water shortage.
