Residential Water & Sewer Inspections

Significant changes to the current process for Single Family Residential (SFR) water inspectionsand sewer service line inspections for 2020.  

This change is intended to provide more flexibility to Builders, including how and when the installation and inspection of residential water and sewer service lines takes place to better fit into each homebuilder’s individual construction process.

Effective July 27, 2020 the Builder will have the option to contract a 3rd Party Engineer of their choice to complete SFR water and sewer service line inspections – OR - to have PWSD complete the inspections (consistent with the current process.)  PWSD will continue to offer to conduct water and sewer service line inspections through December 31, 2020 – after which it will become mandatory that all water and sewer service line inspections are scheduled by Builders through a 3rd Party, privately contracted engineer.

PWSD has updated the details and specifications related to SFR water and sewer service lines. Any Builder choosing to hire a 3rd Party Engineer prior to the January 1, 2021 deadline will need to meet all new applicable standards/specifications.

Note: If PWSD is completing inspections during the transition period of July 27–December 31, current standards/specifications apply.

This transition period will allow Builders time to incorporate updated standards/specifications, and adjust their construction processes. 

Significant changes to Standards and Specifications include the following:

  • Cleanouts will be required on all sanitary sewer services;
  • A pressure test will be required on all water services – the test will need to be performed at service working pressure OR 50 PSI air test. PWSD approved idler bar (part# FORD IDLER – 2-NL) must be in place for pressure test but will need to be removed prior to meter set;

Here is how the process will work:
