For the City of Cape Town to review

The City of Cape Town has not yet seen this page. It describes the organisation only through what it and its partners have said in public. The Forum has not approached the City of Cape Town about anything. Until the City of Cape Town has approved the text, it may change. Questions for the City of Cape Town:

  1. Is this description of the City and its part in the water fund correct? What would you like to change?
  2. Does the City still fund clearing through the Greater Cape Town Water Fund, and in which catchments?
  3. Which office at the City deals with the Western Cape Water Supply System and catchment work, for readers who want to ask about it?
  4. Should readers reach you through the moderators, or through a public contact?

The City of Cape Town is the metropolitan municipality for Cape Town [IC]. It is a separate municipality from Theewaterskloof, of which Ward 2 is a part [IC]. The City draws much of its water from the Western Cape Water Supply System, whose largest dam, Theewaterskloof, lies upstream of the valley on the Riviersonderend [IC]. In 2018 the City and The Nature Conservancy set up the Greater Cape Town Water Fund to clear invasive plants from the catchments that feed its dams [MS].

  • [MS] Mission-Sourced. Comes from the organisation’s own releases or website, or from the releases of its partners in the same programme. It has not been checked against sources that do not depend on them.
  • [TBV] To Be Verified. Seems likely, but nobody has confirmed it in writing yet.

What it does

The City provides water and other municipal services to Cape Town [IC]. Its dam-level reports list six major dams in the Western Cape Water Supply System, which hold 898,221 megalitres when full [IC]. Theewaterskloof holds 480,188 megalitres of that, a little over half [IC]. The dam is owned by the national Department of Water and Sanitation, and its water reaches Cape Town through a tunnel to the Berg River side of the mountains [IC].

How its work reaches the valley

The water fund. The City and The Nature Conservancy set up the Greater Cape Town Water Fund in 2018 as a partnership between public bodies and private companies [MS]. The City sits on its steering committee [MS]. In 2021 the City committed R62 million over three years for clearing in the upper catchments of the Wemmershoek, Steenbras, and Berg River dams, matched rand for rand by The Nature Conservancy [MS]. None of these is the Theewaterskloof catchment.

The bond. The releases about the Cape Water Performance-Based Bond do not name the City as a party [MS]. The bond pays for clearing through the fund the City helped set up [MS].

The valley. Theewaterskloof Dam, on the Riviersonderend near Villiersdorp, is the largest dam in the Western Cape Water Supply System [IC]. The valley lies downstream of it, where the Gobos and Baviaans rivers join the Riviersonderend [IC]. Wild Restoration, which clears invasive plants in the Riviersonderend mountains above Greyton, has told the Forum that the Greater Cape Town Water Fund supports clearing in those mountains through a partnership with CapeNature [TBV]. Which slopes that covers, and whether they drain into the dam or into the valley’s own rivers, is not yet known.

Where it touches this site

  • From Water Access to Water Agency, an idea not yet agreed, names the City as one possible buyer of water the valley could add to the river. The City has not been asked.
  • Ridge to River to Table, an idea not yet agreed, explains how Theewaterskloof Dam sends water both to Cape Town and down the Riviersonderend.
  • National Water Act, the law under which water from the dam is shared.
  • The Municipality, the history of local government in the valley, which is Theewaterskloof’s and not the City’s.

What is still open

  • Whether the City still funds clearing through the water fund, and in which catchments.
  • Whether the City has any role in deciding how much water Theewaterskloof Dam releases down the Riviersonderend. No source has been found.
