The Sugarbird Manor Guesthouse and a number of residences on the Protea Heights farm all utilize water from two boreholes on the site. The water is exceptionally pure with the result that it is highly corrosive. This was leading the usual problems associated with corrosive water in domestic applications, namely:

  • burst geysers
  • laundry staining
  • staining of sanitary ware
  • pipe bursts

A2V designed and installed a limestone contact tank on the rising main from the borehole pumps to the main reservoir which resolved the problems previously experienced. Partial stabilization of corrosive water with limestone has been shown be the CSIR to be a low maintenance and cost effective method of reducing corrosion in plumbing systems.

A2V also implemented a disinfection program at the main reservoir to ensure that any bacterial contamination of the groundwater would be neutralized. This was achieved by using slow release Calcium hypochlorite tablets in a floating dispenser.
