The Authority’s present maintenance program of frequent inspections helps to detect stoppages, deterioration or faulty operation. The frequency of routine inspections will increase as the system ages.

The Authority is committed to inspect approximately 20% of the system yearly including main interceptors and collector lines.

On January 8, 2004 the Collier Township Municipal Authority executed the Allegheny County Health Department Administrative Consent Order that mandates the reduction or elimination of inflow and infiltration within the sewage collection system. Compliance with the Consent Order will require an extensive investigation of the entire sewer system by May 31, 2010.

System inspections should achieve these objectives.
· Promptly repair any damaged or deteriorated portions of the sewer system.
· Remove and replace broken manhole castings and lids.
· Uncover buried manholes and raise manhole casting to grade.
· Routinely clean operations to remove roots, grease accumulation, grit, and debris.
· Flushing of lines having low flow.
· Record sources of excess inflow and/or infiltration and make corrections.
