VillageWaters Project
VillageWaters suggest most effective wastewater treatment solutions in scattered dwellings households, which use their own, independently operated water purification systems.

Helping Homeowners
Environmentally oriented families and homeowners, who live in scattered dwellings areas, where connecting to larger wastewater plants is not option because rural distances.
