Nonconventional Onsite Wastewater Treatment Systems (NOWTS)
The Los Angeles County Code
defines parameters for the effective percolation of
wastewater effluent through the soil. Properties that
conform to the established parameters may be approved
for installation of a Onsite Wastewater Treatment System
(OWTS). In some areas of the County, percolation
absorption rates exceed the parameters. In these areas,
the property owner may apply for approval of a
Non-Conventional Onsite Wastewater Treatment System (NOWTS).
The Land Use Program staff reviews work plans and
required covenants, coordinates with other County and/or
City Departments, and performs installation inspections
prior to final approvals.
