Water Rate Study
The most recent water Rate Study was completed and approved by City Council in 2008. The study determined appropriate rates to fund the ongoing operations and maintenance of the Cities water system. A copy of the final study is available here.
City of Manteca – Report to Consumers on Water Quality
Date of Report: June 2015
(El informe contiene información importante sobre su agua potable.
Tradúzalo o hable con alguien que lo entienda bien.)
The Safe Drinking Water Act requires that utilities issue a water quality report to consumers in addition to other notices that may be required by law.
This report details where our water comes from, what it contains, and the risks our water testing and treatment are designed to prevent.
The City of Manteca is committed to providing you with a safe and reliable water supply. Informed consumers are our best allies in maintaining safe drinking water.

The City of Manteca Water Conservation Program runs all year long, starting January 1, 2015.
The City of Manteca water supply comes from 15 groundwater wells, each with a limited capacity for production. With a conscientious Water Conservation Program we can allocate the existing supply to more homes and people, while slowing down the rate at which we need to build new wells.
In addition, the increased usage pulls water from the aquifers faster than it is being replenished. This creates an "over-draft" of the groundwater supply, thereby lowering the water table. The water table level in the Central Valley has been dropping steadily for over 30 years and it is time to reverse this trend.
If you think about water conservation before using water, it becomes easy to use less. The majority of over-use of water is landscape watering - the tendency for the majority of the population is to use more water than is necessary which leads to run-off and waste.
Inside Water Conservation Tips
- Install a low-flow showerhead.
- Install a soak and soap valve in the shower to allow you to reduce or stop the flow without adjusting any settings.
- Install faucet aerators.
- Turn off the water while shaving, washing or brushing your teeth.
- Run full loads in dishwashers and washing machines.
- Do not use the toilet as a trash can since it requires water to flush the trash.
- Install an ultra low flow toilet. You could save up to 20% on your water bill. Old toilets use up to 7 gallons per flush, but by switching to a new toilet you can reduce that to 1.5 - 2.0 gallons.

- Adjust the water level in your clothes washer to fit the load being washed.
- Place a container of drinking water in the refrigerator instead of running water to get a cold drink.
Outside Water Conservation Tips
Data and underlying analysis relied upon to determine the conservation standard reported to State Water Resources Control Board
- Plant native or warm-season grasses and drought-tolerant or water-efficient plants.
- Use a broom, NOT WATER, to clean sidewalks, driveways, patio and other non-landscaped areas.
- Cover your swimming pool to reduce the amount of evaporation.
- Install drip irrigation. It saves water and reduces weeding by placing the water only where you want it.
- Early morning watering is ideal when temperatures and wind speed are the lowest. Mid-day watering in hot weather wastes water due to high evaporation rates.
- Coordinate your watering schedule with the California Irrigation Management Information System (CIMIS): http://www.cimis.water.ca.gov/
- Check your sprinkler system weekly to guard against misdirected or broken sprinklers. Position the sprinklers to water your lawn and shrubs and not paved areas
- Water your lawn only when it needs it. Monitor your irrigation schedule if you have an automatic timer. Adjust or deactivate your sprinklers accordingly, as needs change.
- Mow your lawn higher during hotter months. Longer blades of grass cool the surface of the ground and reduce evaporation.
- Use an auto-shutoff spray nozzle while washing your automobile or watering your garden.
