Nashville sprinkler and irrigation installers face a Middle Tennessee climate that swings from humid August stretches above 90 degrees to January freezes that drop below 20 degrees. That range pushes design choices on zone count, head selection, freeze drain placement, and winterization blowout pressure. Davidson County properties served by Metro Water Services must follow Tennessee Department of Environment and Conservation Rule 0400-45-01 cross-connection control standards, which require a tested reduced pressure principle assembly or pressure vacuum breaker on any new lawn irrigation tap. Backflow assemblies must be tested annually by a Tennessee Backflow Prevention Assembly Tester (BPAT) holding ASSE 5110 certification. This guide profiles three Nashville-area firms with documented track records on residential and light commercial irrigation work across Davidson, Williamson, and Sumner counties. Verified phone numbers, addresses, and founding details follow each profile. Reference sources include the Tennessee Department of Commerce and Insurance at https://www.tn.gov/commerce.html and the Irrigation Association at https://www.irrigation.org/.

1. Aqueduct Irrigation #
Aqueduct Irrigation has worked Middle Tennessee lawns since 1988 from a base serving Nashville, Franklin, and Brentwood. The firm pairs irrigation with outdoor lighting under the Southern Light brand, allowing crews to share trenching and conduit routes on combined projects. Aqueduct lists landscape irrigation design and installation, system activation, repair, winterization, backflow testing, coverage audits, irrigation pump service, and annual maintenance as core services.
Backflow and Cross-Connection Service #
Tennessee requires annual backflow testing on any irrigation tap connected to a potable supply. Aqueduct performs backflow assembly testing and replacement, which keeps Metro Water Services and Harpeth Valley Utility District customers in compliance with TDEC Rule 0400-45-01. Crews replace failed reduced pressure principle assemblies and pressure vacuum breakers, then file the test report with the local utility.
Coverage Audit and Zone Rework #
The firm runs zone-by-zone coverage audits using catch cups to measure precipitation rate and distribution uniformity. Audit findings drive head replacement, nozzle adjustment, and pressure regulator additions on zones running outside the 30 to 65 psi rotor and spray operating window.
Winterization #
Aqueduct schedules October and November blowouts. Compressed air at controlled cfm clears lateral lines and pop-up bodies, which protects PVC laterals and brass valve seats from freeze damage during Davidson County cold snaps.
Address: Service area covers Nashville, Franklin, Brentwood, Belle Meade, and Hendersonville; physical office address not published online
Phone: (615) 256-5293
Hours: Monday through Friday, daytime appointment-based scheduling
2. Southern Irrigation #
Southern Irrigation opened in 2005 and operates out of 2931 Dickerson Pike on the north side of Nashville. The firm runs residential and commercial irrigation crews across Arrington, Brentwood, College Grove, Franklin, Gallatin, Hendersonville, Lebanon, Mount Juliet, Murfreesboro, Nolensville, Smyrna, and Spring Hill.
Commercial Grading and Booster Pumps #
Southern Irrigation handles commercial grading on light commercial sites and installs booster pump systems for properties with low static pressure from the meter. Booster packages typically pair a centrifugal pump with a small bladder tank and pressure switch, which lets rotor zones reach the 45 to 65 psi range that delivers proper rotation arc.
Seasonal Start-Up and Winterization #
The firm offers spring start-up and fall winterization on annual service plans. Start-up checks include valve actuation, controller program review, and head adjustment after winter heave. Fall blowouts use compressed air at zone-appropriate cfm to evacuate water from poly and PVC laterals.
Lighting Integration #
Southern Irrigation also installs outdoor lighting, which lets the firm share trench paths on combined irrigation and low-voltage lighting projects.
Address: 2931 Dickerson Pike, Nashville, TN 37207
Phone: (615) 332-7933
Hours: Appointment-based scheduling for installations and service
3. B&E Irrigation and Landscaping #
B&E Irrigation and Landscaping has worked Nashville lawns since 1988 from 219 Whitsett Rd in the 37210 ZIP, south of downtown near the Fairgrounds and Wedgewood-Houston corridor. The firm pairs irrigation design and installation with full-service landscape maintenance, having expanded in 2011 through acquisition of a Nashville landscape company. Crews cover both residential and light commercial sites across Davidson and Williamson counties.
Residential and Commercial Scope #
B&E runs separate residential and commercial crews. Residential work covers full-yard sprinkler design and installation, repair, controller programming, and ongoing maintenance plans. Commercial work covers HOA common areas, multifamily property landscapes, and small commercial sites that need a single contractor handling both irrigation and turf upkeep.
Irrigation and Landscape Integration #
Pairing irrigation with landscape maintenance lets a single contractor coordinate trenching, sod placement, mulch refresh, and seasonal cleanups under one schedule. That coordination matters on new construction lots in Brentwood and Forest Hills where landscape installation runs parallel to irrigation start-up.
Service Plans and Long-Tenure Crews #
The firm publishes annual maintenance plans that cover spring start-up, mid-season audits, fall winterization, and controller program review. A 1988 founding date places B&E among the longer-running Nashville irrigation firms, with field crews that have worked Davidson County soil profiles across multiple drought and freeze cycles.
Address: 219 Whitsett Rd, Nashville, TN 37210
Phone: (615) 834-5356
Hours: Monday through Friday 8am to 5pm, closed weekends
Selection Methodology #
Three signals shaped the editorial selection. First, verified tenure in Middle Tennessee: Aqueduct Irrigation dates to 1988 and Southern Irrigation to 2005, which spans multiple drought cycles, the 2010 Nashville flood recovery, and the February 2021 freeze event. Tenure matters because Tennessee soils run from Davidson County limestone clay to Williamson County silt loam, and crews need years of field exposure to read each soil type’s percolation rate. Second, regulatory framework alignment: each firm offers backflow testing service, which TDEC Rule 0400-45-01 and Tennessee Code Annotated Title 68 Chapter 221 require annually on potable-connected irrigation. Third, scope breadth: each firm handles design, installation, repair, and winterization in-house rather than subcontracting any leg. Firms operating purely as repair-only outfits, or firms without a verifiable Nashville-area physical or service presence, were excluded. The Tennessee Department of Commerce and Insurance license lookup at https://verify.tn.gov/ and the Irrigation Association certified contractor directory at https://www.irrigation.org/ were consulted as cross-references during research.
Frequently Asked Questions #
Q: Does Tennessee require a separate license to test backflow assemblies on irrigation systems?
A: Yes. The Tennessee Department of Environment and Conservation requires that any annual cross-connection test on a reduced pressure principle assembly or pressure vacuum breaker be performed by a certified Backflow Prevention Assembly Tester holding ASSE 5110 certification. Metro Water Services in Davidson County accepts test reports filed by certified BPATs only. Test reports must be filed within 30 days of test date.
Q: What pressure setting do Nashville installers use for fall winterization blowouts?
A: Compressed air blowout pressure should stay at or below 80 psi for PVC mainlines and 50 psi for poly laterals, with cfm sized to the zone flow rate rather than to a fixed pressure number. The Irrigation Association recommends moving air at a rate roughly equal to design gpm. Excess pressure cracks fittings and pop-up bodies, which surfaces as zone failures during spring start-up.
Q: Are any of the three firms paid placements?
A: No. The three profiles above are editorial selections drawn from publicly verifiable sources. No firm sponsored placement.
Q: How does a smart controller like WeatherTRAK, Rain Bird ESP-TM2, or Hunter Hydrawise change water use on a Davidson County yard?
A: Smart controllers replace fixed clock schedules with daily evapotranspiration adjustments tied to local weather data, which typically reduces seasonal water application 20 to 40 percent on Middle Tennessee fescue and zoysia lawns. The U.S. EPA WaterSense program at https://www.epa.gov/watersense lists qualifying weather-based controllers. Controllers paired with rain or soil moisture sensors also satisfy current municipal water conservation rules.
