10 Water Conservation Tips for San Diego Homeowners

Living in San Diego means we are all too familiar with water restrictions and drought conditions. But water conservation is not just about following rules, it is about protecting our environment and saving money on utility bills. Here are my top 10 water-saving tips that can make a real difference for your household.

1. Fix Leaks Immediately

A dripping faucet might seem minor, but it can waste over 3,000 gallons per year. A running toilet can waste 200 gallons per day. I have seen water bills double or triple because of undetected leaks.

Check your water meter when no water is being used. If it is still moving, you have a leak somewhere. Common culprits include toilet flappers, faucet washers, and outdoor irrigation systems.

2. Install Low-Flow Fixtures

Modern low-flow showerheads and faucet aerators use significantly less water without sacrificing performance. A standard showerhead uses 2.5 gallons per minute, while a WaterSense labeled showerhead uses 2.0 GPM or less, a 20% savings.

The best part? These fixtures are inexpensive and easy to install. Most homeowners can swap them out in minutes with no special tools required.

3. Upgrade to a High-Efficiency Toilet

If your toilets were installed before 1994, they probably use 3.5 to 7 gallons per flush. Modern high-efficiency toilets (HETs) use just 1.28 gallons or less. For a family of four, upgrading could save 16,000 gallons per year.

Many San Diego water agencies offer rebates for toilet upgrades. Check with your local water district to see what incentives are available.

4. Shorten Your Showers

Every minute you cut from your shower saves 2 to 2.5 gallons of water. A family of four each reducing their shower time by just 2 minutes can save over 7,000 gallons per year.

Try using a shower timer or playing a 5-minute song to keep track. And turning off the water while you lather up can save even more.

Pro Tip from Isaac

Install a hot water recirculation system if you find yourself running the tap for minutes waiting for hot water. These systems keep hot water ready at the tap, eliminating waste and providing instant hot water. They can save the average household 12,000 gallons per year.

5. Only Run Full Loads

Whether it is your dishwasher or washing machine, wait until you have a full load before running it. Modern dishwashers actually use less water than hand washing when fully loaded, typically 4 to 6 gallons versus 20 gallons or more for hand washing.

If you must run a partial load, adjust the water level settings accordingly. Many newer machines have sensors that automatically adjust water usage based on load size.

6. Insulate Your Hot Water Pipes

Insulating hot water pipes reduces heat loss, which means you waste less water waiting for it to heat up. Pipe insulation is inexpensive and a simple DIY project. Focus on the first 6 feet of pipe from your water heater.

7. Capture and Reuse Water

Place a bucket in the shower to capture water while you wait for it to warm up. Use this water for plants, cleaning, or flushing toilets. You can also reuse cooking water from pasta or vegetables once it cools.

Consider installing a rain barrel to capture rainwater for outdoor watering. While San Diego does not get much rain, every bit helps during the rainy season.

8. Water Your Lawn Wisely

Outdoor watering typically accounts for 50% or more of residential water use. Water early in the morning (before 6 AM) to minimize evaporation. Check your irrigation system regularly for leaks, broken heads, and proper coverage.

Better yet, consider replacing thirsty lawns with drought-tolerant landscaping. Many water agencies offer turf replacement rebates of $2 to $4 per square foot.

9. Check Your Water Heater Settings

If your water heater is set too high, you mix in more cold water to reach a comfortable temperature, essentially wasting the energy used to overheat the water. Set your water heater to 120 degrees Fahrenheit for optimal efficiency and safety.

10. Schedule a Plumbing Efficiency Audit
