What are the Triggers that require a PSL inspection and test?

  • When a property owner submits a building permit application for improvements valued at $50,000 or more over a cumulative three-year period, or when the permit improvements involve legalizing or constructing ADU, size change of a water meter or install of fire sprinklers, fixture count change, or District manager request.

​How do I test a Private Sewer Lateral (PSL)? 


 You can have a test conducted. The test should be witnessed by the District’s authorized representative(s) to verify that all Private Sewer Lateral associated with the parcel pass a pressure test and comply with the ordinance, district standards and details and the municipal code.
 
There are two types of tests:
  • Air pressure test: The air test pressure in the private sewer lateral shall be between four (4) psi maximum and three and half (3.5) psi minimum at the beginning of the test. For all lateral pipe diameters there shall be no pressure drop over 15 minutes test period. Any leaks discovered shall be repaired.
  • Water pressure test: The water testing of the private sewer lateral shall be with a riser at least eight (8) feet in height from the crown of the sewer at the upstream Manhole or cleanout or from the surface of ground water, whichever is higher.  For all lateral pipe diameters there shall be no water level drop over one (1) hour test period. Any leaks discovered shall be repaired.

What is the 180-day extension? 


It is the grace period between the time you have your private sewer lateral (PSL) tested and repaired or replaced if required. Property owners with portions of shared laterals may apply for a one-time, 180-day extension that is intended to assist with additional time to schedule needed repairs or replacements. If you are wondering if this extension can apply to you, please contact our Associate Civil Engineer, Fernanda Stefanick by calling 415-927-5792 or via email at fstefanick@tcmmail.org 

Do I need to pass a pressure test to comply with the Private Sewer Lateral (PSL) Ordinance? 


Yes. The only way to test and verify that the PSL is free of leakage is by passing a pressure test.

Do I need a sewer permit for a pressure test? If so, how much does it cost?


Yes. You still need a sewer permit for a pressure test. The cost is $150 per inspection if there is no work to be done on the PSL.  If you already have a sewer permit to do a spot repair or full replacement, the inspection fee is already included in the permit fees.

Is the CCTV a test? 


No. CCTV  standards for closed-circuit television and is an inspection that is necessary in order to verify the condition of the PSL before the actual test is conducted. 

How long is my PSL inspection certification good for? 


For a complete replacement, after passing a pressure test, your PSL inspection certification is good for 10 years. With a previous record of replacement, your PSL is good for 10 years from the date of installation on record. For all others, the PSL inspection certification is good for 3 years. 

If I have a shared lateral do I need to inspect and test my PSL or am I exempt?


Yes. You still need to inspect and test your PSL. However, portions of shared laterals may apply for a one-time 180-day extension to assist owners with additional time to schedule needed repairs or replacement. If you are wondering if this extension can apply to you, please contact our Associate Civil Engineer, Fernanda Stefanick by calling 415-927-5792 or via email at fstefanick@tcmmail.org 

My property is part of a Homeowners Association (HOA) and the HOA is responsible to maintain my PSL. What do I need to do?


Inform the HOA that your PSL needs inspection and ask them if they already submitted the video and tested the sewer line. If so, they need to provide you with a copy of the letter that states that the HOA is in compliance with the PSL ordinance. You should then submit a copy of the letter to Sanitary District No. 2 (SD2).
If the HOA did not inspect and test the sewer line, the HOA will need to do it and submit it to SD2 for review. The HOA should also send you a letter stating that it is in the process of sending a video and testing the sewer line and that it is also working with SD2 for compliance. You should submit a copy of that letter to SD2.

If I only need to install a backwater prevention device do I still need a sewer permit for the installation? If so, how much does it cost?


Yes, you still need a sewer permit. The cost is $300 (When filling out the sewer permit application, make sure you say that the permit is for a spot repair) and the permit fee includes the approval of the work and inspection fees for the test.

Do I need to do a compaction test if the Town is doing a paving project on the street?


Yes. It’s also part of the revised encroachment permit so it should be standard on all projects in the right-of-way.
