Saving Money on Sewage Fees with a Dedicated Irrigation Meter in Pflugerville
If you live in Pflugerville and have a large lawn or pool, you are likely paying sewer fees on water that never enters the city’s wastewater system. The City of Austin’s wastewater averaging program charges you based on your highest winter water usage, assuming that peak represents indoor consumption. But in Pflugerville’s hot Central Texas climate, much of that water goes to irrigation or pool filling. A dedicated irrigation meter separates outdoor water use from your sewer bill, potentially saving you hundreds of dollars per year. City of Austin Water Utility.
The solution is straightforward: install a second water meter dedicated to outdoor use. This meter tracks only the water used for irrigation, pools, and other exterior needs. Since that water does not enter the sewer system, it is not subject to wastewater fees. The upfront cost of installation is often recovered within one to two years through lower monthly bills. Pflugerville homeowners with large landscapes or pools stand to benefit the most. Water Heater Maintenance Tips.
Before you start, understand that this is not a DIY project. The City of Austin requires permits, inspections, and specific backflow prevention devices to protect the public water supply. A licensed Master Plumber must handle the installation to ensure compliance with local codes and to avoid fines or water service interruptions.
How Austin’s Wastewater Averaging Works Against Outdoor Water Use
The City of Austin calculates your annual wastewater fee based on your average monthly water use during December, January, and February. The logic is that these are the months when you use the least outdoor water, so your usage reflects indoor consumption that actually enters the sewer. But in Pflugerville, many homes continue to irrigate during winter on warm days or maintain pool levels. That water is metered but never reaches the sewer, yet you still pay the full wastewater fee on it. Plumbing Pflugerville.
For example, if your winter average is 10,000 gallons per month, you are charged wastewater fees on 10,000 gallons every month of the year—even though your summer irrigation might use 30,000 gallons monthly. A dedicated irrigation meter eliminates this overcharge by tracking only the water that actually goes to the sewer..

Step-by-Step Process to Install an Irrigation Meter in Pflugerville
The process begins with a site assessment by a licensed plumber. They will locate your main water line, determine the best placement for the new meter, and verify that your property meets city requirements. Next, you apply for a plumbing permit through the City of Austin Development Services Department. The permit ensures the work meets the International Plumbing Code as adopted by Austin with local amendments. Plumbing San Marcos.
Once the permit is approved, the plumber purchases the appropriate meter—often a 1-inch or 3/4-inch disc meter depending on your irrigation system size. The meter is installed in a buried valve box near the main line, with a dedicated shutoff and a testable backflow prevention assembly (BPA). The BPA is critical: it prevents contaminated irrigation water from siphoning back into the city’s potable supply. Austin Water requires annual testing of the BPA by a certified tester.
After installation, the city inspects the work. If it passes, Austin Water will activate the meter and update your account to track outdoor usage separately. You will receive two bills: one for the main meter (indoor use with sewer fees) and one for the irrigation meter (outdoor use without sewer fees).
Cost-Benefit Analysis: When Does an Irrigation Meter Pay for Itself?
The break-even point depends on your current water use and the size of your landscape. In Pflugerville, where summer temperatures often exceed 100°F, irrigation systems can easily use 20,000 to 40,000 gallons per month. At Austin’s current wastewater rate of approximately $5.94 per 1,000 gallons, that’s $119 to $238 per month in sewer fees you could avoid.
Installation costs vary but typically range from $1,500 to $3,000, including the meter, backflow preventer, permit fees, and labor. If you save $100 per month on sewer fees, the investment pays for itself in 15 to 30 months. Homes with pools or large gardens often see faster returns.

City of Austin Permit and Inspection Requirements
Installing a secondary water meter is not a simple add-on. The City of Austin requires a plumbing permit from the Development Services Department. The application must include a site plan showing the meter location, the type of backflow prevention assembly, and the plumber’s license information. The permit fee is based on the project scope and typically ranges from $100 to $300.
After installation, a city inspector checks that the meter and backflow preventer meet code. The International Plumbing Code requires that the backflow preventer be installed on the supply side of the irrigation meter to protect the public water system. If the installation fails inspection, the plumber must correct the issue before the meter is activated.
Austin Water also requires that the backflow preventer be tested annually by a certified tester. The test ensures the device is functioning and not allowing reverse flow. Test results must be submitted to Austin Water, and non-compliance can result in water service disconnection.
Why Hire a Licensed Austin Plumber for This Project
Many homeowners consider DIY or unlicensed work to save money, but this project carries risks. An improperly installed meter or backflow preventer can contaminate the public water supply, leading to health hazards and city fines. Unpermitted work can also void your water service agreement and result in costly retrofits.
A licensed Master Plumber understands Austin’s specific requirements, including the correct meter size, valve placement, and backflow assembly type. They also handle the permit process, coordinate inspections, and ensure the work meets all local codes. If a problem arises, a licensed plumber is insured and bonded, protecting you from liability.
Additionally, plumbers familiar with Pflugerville’s soil conditions know how to protect buried lines from the region’s expansive clay. They can install proper bedding and compaction to prevent future leaks or meter damage from soil movement.
Maintenance and Winterization Tips for Your Irrigation Meter
Central Texas winters can bring hard freezes, especially in January and February. While your irrigation system may be inactive, the meter and backflow preventer must be protected. A licensed plumber can install freeze protection, such as insulated covers or heat tape, to prevent damage. Texas State Board of Plumbing Examiners.
During the growing season, check the meter box for debris, standing water, or signs of tampering. If you notice a sudden jump in usage, it could indicate a leak in the irrigation line or a faulty backflow preventer. Annual testing of the backflow device is not optional—it is required by Austin Water and ensures your system is not contaminating the public supply.
If you plan to renovate your landscape or add new irrigation zones, consult your plumber before making changes. Adding zones may require a larger meter or a different backflow assembly to maintain compliance.
