Stormwater Harvesting Could be Cape Town's Water Solution
Published on by Water Network Research, Official research team of The Water Network in Academic
UCT's Future Water Institute Dr Kevin Winter says the proposed Cape Town water tariff for 2018/19 ignores stormwater as a water augmentation opportunity, even though it could be critical in bolstering the city’s scarce water supply and its resilience to climate change.

Thank for your comments.
My main points are to minimize the use of water as a point water supply for irrigation first, and secondly rainwater harvesting.
One of the benefits of rainwater harvesting is the availability of potential energy according to the location of the rainwater harvest, and the other is that the purest water can be obtained at a lower cost depending on the harvesting method. -
RWH at CapeTown may be done if not done already. Make catchment zones 1km by1km.. Cape Town Receives 788mm rain in 100 odd days.. Each zone can store 8000 kl cbm ie 8x 10^6 litres each day . This can cater to 100k people potable needs.... RWH practice calls for 3 elements 1.collection of rain water 2. Cleaning using stone/sand fltrs 3. Charging to ground water aquifers by bores or over land in ponds and lakes.. All done by gravity. At a few places transfer pump to ponds may be done. ... Main aim is not to allow RW to be drained into sea come what may. Motto- catch water where it rains.. Well wishes from Prof Ajit Seshadri.Vels University. Chennai. INDIA ..
