Water Quality Produced
Overberg Water Board has continually maintained good water quality results over the years. As a bulk provider of water, all Overberg Water’s schemes are to comply with standards set out in SANS 241 of 2015. Water quality is managed rigorously and stringent systems are in place to make sure these are met. Overberg Water has set KPIs that are in line with Blue Drop certification requirements and its monitoring and testing processes far outweigh the minimum required by SANS 214. Sampling and analyses are carried out using accredited laboratory techniques (ISO 9001) as far as possible. Overberg Water strives for continued increase in water quality compliance as evident in the increased microbiological compliance trends as shown in tables below. The tables also provide an explanation of the results.
