The current drought is extending its hold on Western Cape municipalities more and more.

It was recently reported that the City of Cape Town - in a collaborative effort from the farming community of the Elgin-Grabouw Valley and the City of Cape Town ‘had secured an extra 67 million litres of water from the Palmiet-Kogelberg Dam’ (per day) for a period of 2 months with effect from February 2018.

The Groenberg Water Users’ Association has made this water available to the City from their irrigation allocation.

Residents of Kleinmond are assured that the Department of Water and Sanitation and th Breede-Olifants-Gouritz Catchment Management Agency (BOGCMA) have confirmed that this does not impact on Overstrand's allocation from the Palmiet River for Kleinmond or on Cape Town's own allocation from the Palmiet River.

BACKGROUND AS PER OVERSTRAND HERALD:

The Palmiet and how the Cape Town water crisis will affect us.

Several readers have sent me questions and news articles that have appeared elsewhere concerning our water situation this week. They are mostly concerned with reports the past week that Cape Town is going to be pumping 67 million liters from the Kogelberg dam to the city. This is the dam that feeds the Palmiet and where we ( Kleinmond ) ultimately get our water from.

First of all, I am no expert on the water supply system to Cape Town. We tried our best to get the opinion of experts from the universities and the city itself during last week, to no avail, but I am going to try and explain the situation as I understand it.

For starters go to google maps and type in kogelberg dam. Go to the satelite version of google maps and enlarge the area. You will hopefully now see the different dams in the area in relation to each other.

Ok, the Palmier river has a large catchment area in the Elgin.Grabouw area. It feeds several smaller dams on private property among them the eikenhof dam. The water that moves through the dam outlets and from the surrounding area mostly lands in the Kogelberg dam. The palmiet river is fed by the Kogelberg but also the mountains along its path to the coast.

Near the Kogelberg dam there is the Rockview dam. Between these two dams there is a pipeline. As I understand it Eskom pumps water between the two dams and by way of an hydro electric plant generates electricity for Cape Town in peak times. According to my information eskom needs as least 16 million cubic meters of water in the kogelberg dam in order to do this. The capacity of the dam is 19 million cubic meters. Which leaves us with a relatively small margin of 3 million cubic meters.

But leave that for a moment.

The Rockview dam is also connected to the Bo Steenbras dam by pipeline. City of Cape Town can pump water from the Bo steenbras to their Faure water treatment plant to supply the city.In the past this has only made up about 4 % of the city's water supply, in other words not very significant - but that has changed now. The other dams have very little water.

The 67 million liters that is going to be pumped from the Kogelberg dam is not water that is supposed to come to us. What has happened is that farmers of the area have offered their water to the city. They have committed to opening their dams ( Eikenhof and various other smaller ones) over a time period of some two or three months. They are talking about 10 million cubic metres. This water will then flow into the Kogelberg dam and then be pumped to Cape Town. In other words we are talking about additional water not the existing water in the Kogelbergdam.
