In the area operated by Vodakva, there is a lack of underground water resources of good enough quality. Therefore, drinking water is mostly made from the surface water sources (87%); the rest (13%) is from underground water. Vodakva operates 27 water treatment plants, the most important of these are: Březová (Stanovice Reservoir), Žlutice (Žlutice Reservoir), Svobodka (Lučina Reservoir), Milíkov (Mže River) and Myslivny (Myslivny Reservoir).
