Wastewater Treatment

Keep our sewer system flowing

Disposing trash, chemicals, or other items directly into a sewer line is against the law and can cause expensive damage to pumps and valves in the sewer system. It is also against the law. 

Help prevent sewer backups in your home and major damage to sewer pipes.

Customers are responsible for the pipes in your home. CVWD is responsible for keeping the sewer pipelines and facilities clear and functioning to provide customers with reliable sewer service

Do not flush these items down the toilet 

• “Flushable” wipes, cotton pads and swabs, facial tissues, or other personal hygiene items go in the trash. Wipes are not flushable, even if the packaging says they are. 
• Paper towels or cleaning wipes should go into the trash can.
• Hazardous waste such as household chemicals, cleaning paint, cement, stucco, or pool grout should be disposed of at a household waste collection site. 
• Medications and prescriptions should be disposed of in a sealed container or at a household waste collection site. Drugs should never be flushed down the sink or toilet.

Do not put these items down the sink drain 

• Scrape hardened grease into the trash can, not into a sink drain or garbage disposal. Grease is a common byproduct of cooking with meat fats, oil, butter, margarine, lard, and shortening. When it enters a home or business’s plumbing system, it sticks to the inside of sewer pipes, causing costly damage. Home garbage disposals do not keep grease out of the plumbing system.
• Paper towels, eggshells, and coffee grounds go in the trash.
