Sewer Use Ordinance

Sewer Use Ordinance

In 1982, the Cary Town Council adopted a Sewer Use Ordinance (SUO). The SUO sets forth uniform requirements for users of the wastewater collection and treatment system of the Town of Cary. In 1984, the Town acquired an approved Industrial Pretreatment Program from the NC Division of Water Quality.

Since 1982, modifications and updates have been made to the SUO to allow for changes in federal and state regulations as well as the adoption of the Town's Fats, Oils, and Grease (FOG) Control Program.

Details

The SUO enables the Town to comply with permits and all state and federal laws, including the Clean Water Act and the General Pretreatment Regulations. Objectives of the SUO include:
  • To prevent the introduction of pollutants into the wastewater system, which will interfere with the operation of the system or contaminate biosolids;
  • To prevent the introduction of pollutants that will cause pass through to the waters of the state or will otherwise be incompatible with the wastewater treatment system;
  • To promote reuse and recycling of industrial wastewater and residual solids from the municipal wastewater system;
  • To protect municipal personnel who may be affected by untreated wastewater, biosolids, and treated wastewater as well as protect the general public;
  • To provide for equitable distribution of acquisition, operation, maintenance, and improvement of the municipal wastewater system; and
  • To ensure that the Town complies with its wastewater discharge permits, non-discharge permits, biosolids use and disposal requirements, and any other state or federal law to which the Town is subject.

The Town’s Pretreatment Division oversees the Town’s SUO and is primarily focused on commercial and industrial wastewater customers who may contribute process wastewaters that could have significant impact on the wastewater treatment system. The pretreatment program also provides public education for residential wastewater customers.
