Understanding EBMUD’s Private Sewer Lateral (PSL) Program for East Bay Homeowners

If you own a home or property in the East Bay, you may have encountered the term “Private Sewer Lateral” (PSL) compliance—especially if you’re selling, buying, or renovating a property. Managed by the East Bay Municipal Utility District (EBMUD), the PSL program plays a vital role in maintaining the region’s aging wastewater infrastructure and protecting San Francisco Bay from pollution. In this post, we’ll break down everything you need to know about the PSL program and how to navigate its requirements.

What Is a Private Sewer Lateral (PSL)?

A private sewer lateral is the underground pipe that connects your property’s plumbing system to the public sewer main, typically located in the street. While public sewer mains are maintained by local utilities, the PSL is the property owner’s responsibility to repair and maintain.

Over time, PSLs can crack, leak, or become obstructed, allowing rainwater or groundwater to infiltrate the sewer system. This excess water can overwhelm wastewater treatment facilities and lead to untreated sewage being discharged into San Francisco Bay.

Why Does the PSL Program Exist?

EBMUD’s PSL program was established to reduce the amount of rainwater infiltration and inflow into the sewer system. By ensuring private sewer laterals are in good condition, the program helps:

Protect water quality in San Francisco Bay.
Reduce the risk of sewer overflows during heavy rain.
Preserve the region’s aging sewer infrastructure.

Who Needs to Comply with the PSL Program?

Under EBMUD regulations, PSL compliance is required in the following scenarios:

When Selling a Property: If you’re transferring ownership of a property in the EBMUD service area, you’ll need a Compliance Certificate to complete the sale.
During Major Remodels: Projects that exceed $100,000 in construction costs or include work on the property’s plumbing system may trigger PSL compliance.
For Multi-Family and Commercial Properties: These properties must obtain a Compliance Certificate even if there is no sale or remodel, with periodic inspections required every 10 years.

Steps to Achieve PSL Compliance

1. Inspection

The first step is to hire a certified plumber to inspect your PSL. They will use video equipment to assess the condition of the pipe and identify any issues such as cracks, root intrusions, or blockages.

2. Repairs or Replacement

If your PSL is damaged, you’ll need to repair or replace it. Work must meet EBMUD’s stan

ethods may be an option to minimize disruption.

3. Testing

Once repairs are completed, the PSL must pass a water or air pressure test conducted by your plumber. The results are submitted to EBMUD as part of the certification process.

4. Obtain a Compliance Certificate

After successful testing, EBMUD will issue a Compliance Certificate, valid for:

20 years for a fully replaced PSL.
7 years for repairs or partial replacements.

The certificate is required to finalize a property sale or demonstrate compliance during construction projects.

Exceptions and Exemptions

Some properties may qualify for exemptions, including:

Properties in areas with separate stormwater and sewer systems.
Newly built properties with PSLs installed within the last 10 years.

Check with EBMUD to determine if your property is eligible for an exemption.

Tips for Navigating PSL Compliance

Plan Ahead: If you’re selling your home, start the PSL process early to avoid delays in closing. Repairs and inspections can take weeks or months, depending on the condition of your PSL.
Budget for Costs: PSL repairs or replacements can range from a few thousand dollars to over $10,000, depending on the extent of the work. Factor this into your financial planning.
Choose Experienced Contractors: Work with certified plumbers or contractors who have experience with EBMUD’s requirements to ensure the process goes smoothly.
Keep Records: Retain copies of your Compliance Certificate and related documentation for future reference.
