Before installing any wastewater treatment system you must consult your town council, the regional government and the relevant river basin authority (Confederaci\u00f3n Hidrogr\u00e1fica), since the type of treatment required, the minimum distances, the discharge authorisation and other conditions vary according to the location and each specific case.
