The Los Angeles County Waterworks Districts are offering a free water survey to determine if residents’ homes are wasting water.

Services provided at no cost include: checking faucets and replacing aerators if needed; checking for leaks in toilets, sinks and baths; checking showerhead flow rates; checking washing machines and other water-using appliances; providing an outdoor watering schedule, and checking the sprinkler system for problems.

Waterworks officials say that benefits include improving overall water use efficiency; teaching residents how to find leaks in their home and sprinkler system; helping the community conserve water; and potentially lowering residents’ water bill.

Water conservation rebate programs are offered as well, with $150 for a high efficiency clothes washer; up to $150 for a high efficiency or dual-flush toilet; $150 for a smart sprinkler controller; $4 each for a rotating sprinkler nozzle; 30 cents per square foot for synthetic turf; $60 to $120 for an upgrade to a commercial waterless urinal and $150 for a new installation; and $50 for drip irrigation.

To cut water use by 15 percent both outdoors and indoors, the following recommendations are made:

Water the yard between 5 p.m. and 10 a.m. to reduce evaporation from wind and heat.

Install rotary sprinkler nozzles, a weather-based sprinkler controller or drip irrigation.

Check the sprinkler system weekly to make sure you’re watering plants and not the sidewalk.

Fix all leaks, indoors and outdoors, and fix broken, leaking or clogged sprinkler heads.

Reduce outdoor watering to two days per week, and replace the lawn with native and drought-tolerant plants or permeable surfaces such as concrete grids or stone surfaces.

Use a broom instead of a hose to clean sidewalks and driveways. Take the car to a car wash.

Use an automated shut-off hose nozzle. Don’t use decorative fountains, waterfalls or ponds unless they have a recirculation system, and cover swimming pools and spas when not in use.

Indoors, install low-flow showerheads and faucet aerators, install high-efficiency toilets, a high-efficiency clothes or dish washer, and run only full loads in the dishwasher and clothes washer.

Install a tankless water heater; turn off the tap when shaving or brushing teeth; take a five minute shower; use a bucket to capture water that runs through while waiting for it to get hot and use the excess to water plants.
