Water Conservation

The City of Manteca Water Conservation Program runs all year long, starting January 1, 2015.

The City of Manteca water supply comes from 18 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. 

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.

Don't use the toilet as a trash can; every flush can use up to 7 gallons of water.

Install an ultra-low-flow toilet. You could save up to 20% on your water bill. The toilet will end up paying for itself with the savings!

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.

Plant native or warm season grasses and drought-tolerant or water-efficient plants.

Use a broom, NOT WATER, to clean sidewalks, driveways, patios, 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):

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.
