Wastewater

Overview

CVWD currently operates and maintains approximately 421 miles of wastewater collection system ranging from 8 to 36 inches in diameter. Wastewater that is generated by CVWD’s customers is transported through this collection system and sent to IEUA Wastewater Treatment facilities where it is processed into recycled water.

The CVWD Wastewater Utility Department provides quality maintenance to the wastewater collection system and ensures that the sewer mainlines are flowing properly at all times. The primary task of this department is performing preventative maintenance on the system through sewer line cleaning and video inspection programs. This is done using a high pressure water jetter to clean the sewer line, or if necessary, vacuuming debris from the pipeline. This work ensures that the system is flowing properly and eliminates sewer backups in the future.

CVWD staff use Closed Circuit Television (CCTV) inspection trucks to remotely televise the internal condition of pipes and flow of the wastewater system. This allows the District to proactively target locations of necessary repairs related to tree root intrusion, blockages and damaged lines. CVWD address all sewer calls from our customers with an emergency response timeline.

FOG and Wipes

Fog refers to fats, oils, and grease that originate in kitchen households. When improperly disposed of, these items stick to the inside of sewer pipes and over time lead to a blockage. As well, flushable or disposable wipes that are flushed down the toilet will clog sewers and cause backups.

How Can You Help?

Do not pour FOG down the drain
Wipe pots and pans with a paper towel or napkin prior to washing
Pour cooking oil and grease into a container to store for recycling
Dispose of wipes in the trash
Only flush toilet paper down the toilet

For more information about the proper disposal of FOG and wipes view our What Goes Down the Pipes and What Does Not Brochure.
