The City operates 20 wells that produce 5 billion gallons of safe drinking water each year to the City of Woodland. Two employees inspect and test these wells to keep the system operational and fully compliant with federal and state water quality requirements.
The City now has an improved systematic flushing program. Two employees are flushing the water mains on a year round basis to remove sediment and improve water quality to our customers. Furthermore, this program provides a condition assessment on all fire hydrants and generates repair orders as problems are discovered.
To ensure that we can quickly close down and isolate failed water pipe segments for repair, it is important that the distribution valves are periodically operated and checked. This program is now underway. Two employees are dedicated to exercising and evaluating every valve in the water distribution system. Valves needing work are scheduled for repair or replacement by the in-house crews.
Water Meter Retrofit Program
In January 2006, a state law became effective that requires water suppliers to install water meters and charge for water services based on actual volume of water delivered. Specifically, the city is required, by January 1, 2010, to install water meters and charge for water based on the meter reading for service connections established after 1991. For connections established prior to 1992, the city has until January1, 2025, to install meters and charge by the meter readings. Currently, city staff is planning to begin a meter implementation plan to assess the cost and procedures to best incorporate the program.Informational flyers and workshops will be scheduled at a later date to inform the public on this exciting new plan.If you have any comments, questions, or concerns, please contact Doug Baxter at 530-661-5975.
The quality of water provided to the residents of Woodland meets CDPH and all federal and state drinking water standards. It is thus safe for consumption by all ages and gender. However, some residents use water softeners to reduce the level of the water hardness; this is wholly at the discretion of the resident. You may contact private companies for details on how this works. The City of Woodland recommends using a water softener with a consumption based cycle to help conserve water usage (which will save money in the future) and to reduce the amount of salt in the environment.
How Hard Is My Water?
A concentration of 17.1 parts per million (ppm) of hard water is equal to 1 grain per gallon. Woodland’s water can be as high as 400 ppm, which equals about 23.4 grains per gallon. Water hardness does not affect a person’s health. It leaves mineral deposits over time, may impact the life expectancy of plumbing fixtures and water heaters, and may not be aesthetically pleasing.

Woodland – Davis Water Supply Project
Numerous studies by both the City of Woodland and the City of Davis have independently concluded that there is a need to utilize surface water as a major part of our long-term water supply strategy. Both communities and the University of California at Davis are jointly working on a project that will bring Sacramento River water to our community by the year 2016.
If you have any comments, questions, or concerns, please contact Doug Baxter at 530-661-5975.
A Final Environmental Impact Report (EIR) has been prepared and approved by both cities. It is available for public review at the external website where more information about the project can be found:
In April 2005, the City Council approved a phased increase in water and sewer rates. Currently (as of July 1, 2007) the water rate for a single family home on a medium sized lot is $23.85 per month. Effective July 1, 2008 the water rate for a single family home on a medium sized lot will become $24.80. 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.)

Your water rates pay for many services including:
Maintaining wells that provide drinking water, water quality testing, water storage, and general water system maintenance (e.g., replacing water mains, pumps, valves, fire hydrants and other infrastructure)
System repairs and upgrades and processes necessary to meet new state and federal regulations
Increasing construction, operation, and maintenance costs.
The City of Woodland has groundwater wells and a water storage tank to provide drinking water to the residents, at this time the monitoring of these facilities is done by O&M water crews on a daily basis but that is not frequent enough to allow all the wells to be able to coordinate their pumping sequences based on the water level in the tank. This has resulted in inefficient use of resources, lower than desired pressures, higher electrical pumping costs.
The City is in the process of designing and installing what is called a Supervisory Control and Data Acquisition (SCADA) system for the City’s water system.
The SCADA system goals include but not limited to the following:
- Provide remote monitoring during and after normal business hours
- Immediately activate alarms and call standby operators of problems associated with the water system, provide operator with specific identification problem, and increased public safety
- Provide continuous information and records of the utility system performance to best serve to the public and to improve operational efficiency.
- Enhancement of data logging and report generation capabilities
- Significantly reduce energy consumption.
The controls for the SCADA system shall include activating or recording the following minimum capabilities:
- Water flow measurement from each well.
- Kilowatt measurement (energy usage for each gallon pumped).
- Pressure measurement.
- Water level measurement - to know how full the tank is and to automatically activate water well pumps to maintain proper water pressure.
- Status monitoring - to know what is running and what is ready to come online when needed.
- Automatic failure transfer to existing manual controls.
- Historical data logging - continuously records how the system is responding to water demand.
- On/off control.
- Chlorine Flow Detection.
- VFD control capability - allows some well pumps to vary their pumping speed and related pumping rate to match the water supply with the City’s water demands.
- Nitrate analyzers adaptability.
The SCADA system is a step forward in the City’s monitoring and controlling of the water distributions system that we all use and will be more energy efficient and safer.
The SCADA system will have capability for expansion to serve other City of Woodland utilities and facilities as necessary. The system shall be designed to support and be inclusive of the existing wastewater treatment SCADA system and the SCADA system shall also be expandable in the future to track the operations of the storm-water facilities which consist of a dewatering station, 3 storm-water pumping facilities, and 1 storm-water gate.

Water Tank Retrofit
The City of Woodland at present has one elevated water storage tank in the water distribution system along with 20 groundwater wells that pump water to the residents of Woodland. The purpose of the water tank is for water storage to help meet peak hourly water system demands, provide additional water capacity during emergencies such as fires, and to assist in providing the correct water pressure to customers.
Unfortunately, since the conception of the elevated water storage tank in 1955, the City has grown and its demand on water has also increased. As the City grew the water tank became less and less viable for providing system wide reliable water pressure. The old current tank met the building codes of when it was built. Current building codes provide much higher safety factors for wind and seismic design. A major overall would be required if the old tank was to remain which is not feasible since it is at the end of its useful life expectancy. Utilities Engineering staff is now working with consultants on a new replacement water storage tank plan and is seeking public comments. Likely to occur is some water distribution main enlargement near the tank to improve its flow. The replacement plan will address key issues with the water distribution system and help correct areas of the City that do not receive enough water pressure at certain peak times. In conjunction with the SCADA system plan the tank replacement project will bring a new technological element to allow more efficient ways to manage the water distribution.
