Private service line defect remediation program


The Private Service Line Defect Remediation Program is a component of the City’s comprehensive
CMOM Program and is intended to remediate identified private service line defects, in a timely
manner, to address infiltration and inflow (I&I) into the system that could cause or contribute to


Infiltration and inflow (I&I) are terms used to describe the ways that groundwater and stormwater enter into dedicated wastewater or sanitary sewer systems.  Dedicated wastewater or sanitary sewers are created from pipes located in the street or on easements that are designed strictly to transport wastewater from sanitary fixtures inside your house or place of business. 


Sanitary sewer overflow (SSO) is a condition in which untreated sewage is discharged from a sanitary sewer into the environment prior to reaching sewage treatment facilities. When caused by rainfall it is also known as wet weather overflow.

The purpose of the Private Service Line Defect Remediation Program is to encourage private
service line owners to remediate defects in private service lines that are sources of I&I, and that
could cause or otherwise contribute to the occurrence of SSOs. A primary goal of the Private
Service Line Defect Remediation Program is to delineate a clear process for remediation of
determined defects in residential or commercial private service lines.

Supplemental Environmental Project (SEP)


The Supplemental Environmental Project is a private service line defect replacement program for eligible residential property owners .


The City's Wastewater Collection and Transmission System ("WCTS") becomes a conduit for storm water when defective Private Service Lines allow rain or groundwater to enter the WCTS. The purpose of this Supplemental Environmental Project ("SEP") is to reduce extraneous flows, including inflow and infiltration caused by defects in private service lines serving residences from entering the WCTS through Private Service Lines. This project was undertaken in conjunction with the settlement of an enforcement action, United States et al. v. City of Fort Smith, (C.A. No. 2-14-cv-02266-PKH, W.D. Ark.), taken on behalf of the U.S. Environmental Protection Agency under the Clean Water Act. For purposes of this SEP, a defective private service line is any Private Service Line connected to the WCTS that allows the introduction of extraneous flow or debris, such as storm water, surface water runoff, ground water, roof runoff or root intrusion.


Residential property owners must meet the financial guidelines of family income (Attachment A) in order to qualify for SEP payment of the costs of the Private Sewer Line defect remediation for their homes. The financial guidelines are based on information identifying moderate, low, and very low income residential property owners.
