Country houses do

Topa and Topaero installations practically do not require service. Personal purification occurs without additional introduction of chemicals or bacteria. Organic contaminants are processed by microorganisms already in drains, as well as introduced to the system with air. In addition, the aeration stations of wastewater purification for country houses do not lose their effectiveness even in the conditions of the harsh Russian winter, while not requiring additional heating — there is enough heat released during the life cycle of bacteria.
