According to level 4B water restrictions implemented in the Cape Town region… NO topping up (manual/automatic) of swimming pools with municipal drinking water is allowed, even if fitted with a pool cover. This includes the filling of new pools or the refilling of an existing pool after a repair. This applies to all pools including public pools and pools at clubs, businesses and institutions.
View the Level 4b Restrictions Guide Here. “All water users are required to immediately use less than 87 litres of water per person per day in total irrespective of whether you are at home, work or elsewhere.”
What does it mean for pool owners? You may not top up your pool. Evaporation levels remain throughout the year, levels are less in winter however. Get a pool cover to prevent evaporation of your pool water.
