Wastewater (Sewer)

Drinking Water Quality Affects Wastewater Quality

The quality of our drinking water quality greatly affects the quality of our wastewater discharge water as it relates to salts and boron levels. While our drinking water meets all state and federal standards for human consumption the State Regional Water Quality Control Board (RWQCB) has concerns about the cumulative levels of salt in our rivers. Every five years the City of Woodland has to obtain a new discharge permit for our wastewater treatment facility and we expect the City will have short-term and long-term limits at some point that will require us to utilize water supplies with less salt in them such as receiving water from the Sacramento River. The City of Woodland is in the process of seeking a new wastewater discharge permit at this time (Nov. 2007).

Wastewater Rates

In April 2005, the City Council approved a phased increase in sewer and sewer rates. Currently (as of July 1, 2007) the sewer rate for a single family home on a medium sized lot is $33.00 per month. Effective July 1, 2008 the sewer rate for a single family home on a medium sized lot will become $37.00. Thereafter, the rate will be adjusted annually for inflation, based on the Construction Cost Index. Rates for other property types were adjusted accordingly. (Note: residential properties are billed every other month, so the bi-monthly bill is twice the amount stated above.)

City of Woodland Fee Schedule2007

In general, your sewer rates pay for many services including:

  • Collection and treatment of wastewater from homes and businesses
  • Operation and maintenance of pipes, pumps, and the treatment plant
  • Ensuring compliance with ever changing state and federal regulatory demands for water and sewer system operations, and for wastewater treatment.

The new wastewater rates were key to implementing a multi-million dollar wastewater treatment plant upgrade that was completed in 2007. To enhance the environment, the project included membrane filtration as mandated by the State of California. It also included flood protection for the plant. We have also eliminated the gas chlorination disinfection system and installed a safer and more environmentally friendly ultraviolet light disinfection system. These changes have significantly higher operating cost associated with them but also provide significant benefits for the environment. Development fees will pay 100% of all work associated with plant expansion for growth.

The City has increased its efforts to enhance sewer collection system reliability to prevent sewer blockages or failures, as required by a new state mandated Sanitary Sewer Management Plan.

We now clean and video inspect the sewer system on a five year cycle, and are able to schedule repairs and maintenance based on inspections instead of line failures/sewer overflows. For the inspection of the sewer system, the City purchased two high velocity water jet/vacuum cleaner trucks and the closed circuit video equipment/van, which are used on a year-round basis for both inspections and repairs. This system uses high pressure water to clean the grease buildup and to eliminate tree roots inside the pipelines. The high velocity vacuum capability increases productivity in cleaning manholes, spill cleanup, and spot excavations for repairs. Major repair/rehabilitation projects are scheduled on a more frequent basis. Additional staff has been hired for cleaning/inspection work, and to handle the increased repair workload.
