With the commissioning of the new Preekstoel bio-filtration plant on Tuesday 19 August 2014, the Greater Hermanus bulk water supply system is now fully operational. Work on this project commenced in 2010, with new plant and infrastructure being commissioned in stages from early 2013 onwards.
Referred to by Mayor Nicolette Botha-Guthrie as Overstrand’s “flagship capital works project”, the Preekstoel bio-filtration plant is the first full-scale plant of its kind in South Africa and has been specifically designed to remove the high iron and manganese content from groundwater by means of a natural process.
Generally acknowledged as being much more environmentally friendly, this type of water-treatment technology requires fewer chemicals, saves on electricity and reduces water loss in the treatment process, earning Overstrand an award for innovation as one of the Western Cape’s greenest municipalities in 2013.
