Septic Systems (Onsite Wastewater Treatment Systems)

The most reliable and cost-effective means of disposing of domestic sewage is an adequate public sewer system. It is the policy of the Weld County Board of Public Health and the Board of Weld County Commissioners to require the use of public sewer systems where and whenever feasible and to limit the installation of onsite wastewater treatment systems (OWTS) to areas that are not feasible for public sewers. Because many areas of Weld County are too sparsely populated to be economically served by public sewers, onsite wastewater treatment systems have become a common method of domestic sewage disposal. To preserve the environment and protect the public health, the Weld County Board of Public Health and the  Board of Weld County Commissioners have adopted regulations setting minimum standards for the design and construction of onsite wastewater treatment systems.
