Chris Cowling has submitted the following interesting and indeed important facts about the dams that supply our water

“I have noticed that a lot of emphasis is placed on the level of the Kouga Dam, in relation to our available water supply. I would like to explain the bulk water reticulation lay out for you.

  • Kouga Dam:

Catchment: Kouga and Baviaans mountains.
Supply: Gamtoos Valley (irrigation), Hankey. Patensie, Loerie, Thornhill and PE via a single pipeline.

  • Churchill Dam:

Catchment: North-facing Tstsikamma mountains.
Supply: Humansdorp (augments current supply from springs), Greater St Francis Bay, Paradise Beach, Jeffreys Bay ( augments current borehole supply), Gamtoos Mouth, Van Stadens River Mouth, Sea View. PE.

  • Impofu Dam:

Catchment: Same as Churchill, as well as the south slopes of the Eastern Kouga mountains.
Supply: The same areas as Churchill.

The Churchill pipeline (2 pipelines) crosses the Impofu Dam at the Elandsjagt Treatment Works. This is where the Impofu (Elandsjagt Water Treatment Works) confluences with the Churchill water. The water from Elandsjagt as well as Churchill gravity feeds to PE. Only when the Churchill dam level gets to a low level, do they pump water to PE.

What I hope to have shown you, is the importance of the Churchill and Impofu dam levels are for us. Kouga does not directly affect us.

Thanks Chris much appreciated for I and I am sure many other readers were unaware of these facts.
