Sanitary Sewer System

The City of Pomona Wastewater Operations Division is responsible for the operation and maintenance of an extensive wastewater collection system and is tasked with ensuring proper and efficient operation of the system.  The City provides sewer service throughout the City and to a limited area outside the City limits.  

The City’s wastewater collection system consists of approximately 306 miles of gravity sewer, 4 pump stations, 1.4 miles of force mains, over 6,000 manholes and five siphons.

Sewage collected by the City’s wastewater collection system is conveyed to the Pomona Water Reclamation Plant (PWRP) for treatment and disposal under the authority of the Los Angeles County Sanitation Districts (LACSD).

The City is dedicated to improving the condition and performance of its wastewater collection system and reducing the occurrences of sanitary sewer overflows. 

For more information on the City’s Sanitary Sewer System or wastewater collection system contact Wastewater Division at (909) 620-2251.

 NO WIPES IN THE PIPES

The Covid-19 crisis is having an unintended consequence on the local sewer system and City of Pomona residents are being asked to stop flushing wipes or anything else that is not toilet paper.

As the news of toilet paper shortages continues, we have seen an increase in the number of wipes, napkins, and rags in the sewer system. Wipes are among the leading causes of sewer system backups.

This is a good time to re-emphasize that there is no such thing as “flushable” wipes.

“Flushable” or disinfecting wipes do not break down like toilet paper and they will clog sewer interceptors, pipes, and pumps.

The California Water Board is advising “Flushing wipes, paper towels and similar products down toilets will clog sewers and cause backups and overflows at wastewater treatment facilities, creating an additional public health risk in the midst of the  coronavirus pandemic.”

During an inspection of a City sewer manhole on Thursday, March 19th, staff saw an increased number of wipes, napkins, rags ,and other debris in the system.

City of Pomona residents are being asked to stop flushing wipes or anything else that is not toilet paper.

If wipes are used, they should be thrown in the trash, not down the toilet,” stated City of Pomona Wastewater staff.

When in doubt, residents are asked to remember the 3 P’s

Only flush Pee, Poop and toilet Paper

Anything else should go in a trash receptacle

City of Pomona is dedicated to protecting public health and the environment through effective operations and maintenance.

Sewer Rate

Effective: October 1, 2019 

Sewer Rate

The City’s sewer rates are comprised of a bi-monthly service charge, which collects a portion of the City’s fixed costs in providing sewer system; and a consumption charge which recovers a portion of the City’s fixed costs, and all of its variable costs, in providing sewer service. The bi-monthly service charge is uniform to all properties, and is charged to each account. The consumption charge is applied per unit of water consumption. For residential sewer customers, consumption is based on water usage and is determined based on a customer’s winter water usage, which is defined as an average of two complete months data within the period of December of the previous year through the following March. For all other sewer customers, consumption is based on water usage per billing cycle.

Sewer System Management Plan (SSMP)

The State Water Resources Control Board (SWRCB) adopted Order Number 2006-0003-DWQ, the Sanitary Sewer Systems Waste Discharge Requirements (WDRs), which requires all federal and state agencies, municipalities, counties, districts and other public entities that own or operate a wastewater collection system greater than one mile in length to develop and implement a system specific Sewer System Management Plan (SSMP).  The SSMP documents how an agency manages its wastewater collection system.

 

The SSMP prepared by the City of Pomona is in compliance with the Waste Discharge Requirements (WDR) and documents the City’s system specific plans and programs to operate, maintain, and manage its wastewater collection system.

 

The 2018 SSMP serves as a five-year update to the City’s 2013 SSMP.  Since this has been approved by the City Council on October 15, 2018, it can now be re-certified with the State Water Resources Control Board (SWRCB) so that the City can remain compliant with SWRCB Order Number 2006-0003-DWQ.
