Speeding up Mother Nature's work

Roseville operates a wastewater utility to purify and treat water before it's delivered back to the environment.

  • Operate two wastewater treatment facilities that have the capacity to treat up to 30 million gallons of water daily
  • Maintain 505 miles of sewer mainlines, 246 miles of sewer laterals and 11,195 manholes
  • Deliver one billion gallons of recycled water annually

Roseville's sewer system protects local creeks and river water quality and meets federal standards at the lowest possible cost.

Help with your service

Call us first. We will take care of the next step together.

If you experience sewer backup issues, contact your wastewater collections staff at (916) 774-5750 to evaluate the next step.

This service is available, paid through the monthly rates for wastewater services. We are available 24 hours a day, seven days a week.

As a service, a crew will check to see if the backup is in the city’s main or service. If it is, we will clear the blockage. However, if the blockage is in the lateral serving the residence or business, it is the resident's/business owner’s responsibility to clear any blockage in their lateral line, which connects their property to the City’s.

Living sewer smart

Save your pipes and help protect the sewer system and the environment from unnecessary interruptions. 

  • Fats, Oils & Grease - One of the most important things you can do to keep your sewer pipes clear is to properly dispose of fats, oils, and grease.
  • Flushable wipes - Disposable disinfectant wipes, baby wipes, and even “flushable” wipes cause serious problems in the sanitary sewer system.
  • Tree roots - they seek out water. That's why planting near sewer pipes isn't a good idea.

Sewer System Management Plan

The State Water Resources Control Board requires public agencies that own or operate sanitary sewer systems to develop and implement a Sewer System Management Plan  to reduce the potential for overflows. Agencies are required to report all overflows to the the State Water Board's public online database.

Environmental Utilities has developed a Sewer System Management Plan to minimize sewage spills and measures to effectively clean them up and report them.

Business customers

Food service establishments in Roseville generate a tremendous amount of fats, oils and grease everyday by preparing and serving food to thousands of customers. If not properly disposed, fats, oils and grease can damage and even clog local sewer system, causing a sewer overflow.

To report a sewer overflow, please call 774-5750 immediately.


Produce stickers gumming up our treatment facilities

Smoke testing

We conduct smoke testing as part of routine maintenance of the sewer lines.  These tests involve blowing harmless smoke into the sewer system to find cracks, breaks and other problems with the sewer lines that need repair.

Pure Water Roseville

Despite our successful water recycling program, recycled water distribution for irrigation currently requires dedicated pipe networks. Also, we cannot store a significant volume of recycled water when irrigation demands are low to use when they are higher. As a result, only about 20 percent of our treated wastewater is converted into recycled water.

As a result, we are embarking on Pure Water Roseville.  Like many communities, agencies are focusing on advanced treatment technologies to purify water for storage and other uses. While we are not pursing an active project at this time, we are in the early stages of evaluating these technologies to determine compatibility with our water treatment and delivery systems as well as how they might provide further redundancy and flexibility for our community.

Diversifying our water resources is critically important.  As important is the need to look at increased treatment options to meet the ever-changing requirements in discharging to our waterways.

Wastewater discharge permit

We are responsible for regulatory oversight of sewer discharges to our regional wastewater treatment plants. Working with our industrial and commercial customers, we aim to protect the conveyance system and our treatment plants from harmful discharges by permitting industrial discharges.

Pleasant Grove Wastewater Plant
We operate two wastewater treatment facilities in Roseville, capable of purifying up to 30 million gallons of water a day. Not only are we removing the waste from the water in Roseville, our plants serve as regional facilities. This means we treat the water from portions of Placer County and several incorporated communities.
