The water supplied by SWDE is perfectly drinkable. However, the taste of the water can vary depending on the region and the treatment it has undergone. It is not necessary to filter the water to improve its quality. However, if you do not like the taste of your tap water, you can, of course, use these systems.
You can consult the Blue Book published by Belgaqua to find out all about drinking water and wastewater treatment.
