5 Ways to Cut Your Water Bill With a Smarter Sprinkler System

Is your water bill too high? If you're in Erie or Longmont, you already know that summer water bills can jump to $200-$300 a month once the lawn sprinklers kick on. The good news? Most yards are overwatering by 30-50%, which means there's real money sitting on the table.

Here are five upgrades we install all the time that pay for themselves, usually within one season.

1. Install a Smart Controller

This is the single biggest bang for your buck. A smart controller like the Rachio 3 or Hunter Hydrawise connects to local weather data and adjusts your watering schedule automatically. Rain in the forecast? It skips the cycle. Hot and windy? It adds a little extra.

Most homeowners save 20-40% on water just by swapping out their old timer for a smart controller. That's $40-$80 a month during peak summer. The controller itself runs $150-$250 installed, so you're looking at a payback inside of one season.

Even better, many Front Range water districts offer $50-$150 rebates on smart controllers. The Town of Erie and City of Longmont both have programs. We can point you to the right one.

2. Fix Your Sprinkler Head Spacing

This is the one nobody thinks about. Your heads need to throw water far enough that each one reaches the next head in the row. That's called head-to-head coverage. When heads get knocked out of alignment or the wrong nozzle is installed, you end up with dry spots and soggy spots. Most people just crank up the run time to fix the dry spots, which wastes a ton of water on the spots that were already fine.

A quick nozzle audit and adjustment takes about an hour and can save 10-15% on your water use.

3. Switch to MP Rotator Nozzles

If you've got standard pop-up spray heads, they're putting down water at about 1.5 inches per hour. That's way faster than Colorado clay soil can absorb it, especially on slopes. The water just runs off into the gutter.

Hunter MP Rotator nozzles drop that rate to about 0.4 inches per hour. The water actually soaks in instead of running off. They cost $4-6 per head and we can retrofit them onto your existing spray bodies. For a typical yard with 30-40 heads, that's $200-$300 installed and you'll see the difference on your next bill.

4. Add a Rain Sensor (If You Don't Have a Smart Controller)

If a full smart controller isn't in the budget, at least add a rain sensor. A basic wired rain sensor runs $30-$50 installed. It shuts off your system when it rains and prevents the most obvious waste: sprinklers running during a thunderstorm.

It's not as smart as a Rachio, but it's better than nothing. We see systems running during downpours every single week in summer. That's money down the storm drain.

5. Set Up Cycle and Soak Scheduling

Clay soil is everywhere from Erie to Lafayette. It absorbs water slowly. If you run a zone for 20 minutes straight, the first 10 minutes soak in and the last 10 run off into the street.

Cycle and soak means splitting that 20 minutes into two 10-minute cycles with a 30-minute break in between. The soil absorbs both cycles fully. You use the same total run time but get way better results. Every smart controller does this automatically. On a basic timer, you can set it up with multiple start times.

This alone can cut runoff by 50% and save $15-$25 a month.

Add It All Up

Stack a couple of these together and a $250/month summer water bill can drop to $150 or less. We've seen it happen plenty of times across Erie, Longmont, Louisville, and Lafayette.
