Pretreatment Program

Print RSS

The Pretreatment Program is committed to working collaboratively with citizens, the business community, and other Town staff to protect the environment and our public utilities through building positive relationships while meeting local, state, and federal environmental regulations.

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
  • 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 wastewaters that could have significant impact on the wastewater treatment system. The pretreatment program also provides public education for residential wastewater customers.
