Water Conservation Toilets (Using less than 1.6 gallons per flush)
New York State has mandated low flush toilets in all new and replacement installations since 1992. These toilets reduce the water loading the sewage disposal system, increasing its efficiency. Their use should also extend the life of the leach field and reduce water bills for homeowners on municipal water supplies.
Where no electricity is available to pump water, an elevated storage tank and manual pump can supply the water force necessary to effectively operate low flush toilets.
