Zimmerman, MN · Sherburne County
Sunshine Sprinkler Systems serves Zimmerman, MN with sprinkler installation, repair, spring startup, winterization, and commercial irrigation. Zimmerman has nearly doubled in population since 2000 and remains one of the younger, faster-growing communities in our service area. The city operates its own municipal water system and takes an unusual approach to irrigation restrictions: there are no standing seasonal rules. Watering restrictions activate only when a drought emergency is declared — and when they do, the schedule is nighttime-only, 8 p.m. to 8 a.m., odd/even by address.
Service 01
Zimmerman sits on the Anoka Sand Plain — the same fast-draining sandy soil formation that runs through Ramsey and much of the corridor north of the metro. Sandy soils drain quickly and don't retain moisture between waterings, which has a direct effect on how we program new systems here. A standard single-run schedule that works fine on heavier loam soils will leave sandy Zimmerman turf dry well before the next cycle. We program every new Zimmerman installation with cycle-and-soak scheduling: shorter runtimes repeated across the same watering window so water soaks in rather than running off before it can penetrate.
Zimmerman's municipal water comes from two separate plants with meaningfully different hardness levels. The 4th Ave Water Plant produces water at 9.7 grains per gallon (166 ppm) — moderately hard. The 6th Ave Water Plant runs softer at 8.2 GPG (140 ppm). Mineral content at those levels won't stain concrete or equipment the way iron-heavy water can, but it does deposit scale in drip emitters and rotary nozzles over time. We select heads and nozzles with this in mind and note it during system design so servicing technicians understand the water chemistry they are working with.
Zimmerman's median age is 32.3 — the youngest community in our service area — and the population has nearly doubled since 2000. That combination means a high share of first-time homeowners who have never owned a sprinkler system before. Jon takes time during the estimate to explain how the system works, how the controller is programmed, and what to watch for between service visits. A customer who understands their system calls us for service rather than trying to fix things themselves and making a larger problem.
Additional Services
Sandy soils shift more than heavy clay, which can displace heads and affect spray coverage over time. We also see nozzle clogging from mineral deposits in Zimmerman's moderately hard water, particularly in drip zones and rotary nozzles with small orifices. We carry Hunter, Toro, and Rain Bird parts on every truck and service all makes and models, including systems we did not originally install.
Spring startup in Zimmerman includes pressurizing the system, running every zone, inspecting all heads and spray patterns, and verifying the controller program reflects current scheduling preferences. For first-time system owners, we walk through the controller during startup so you understand exactly how your system is programmed and how to adjust it yourself if needed during the season.
Every irrigation system in Minnesota needs a compressed-air blowout before freeze-up. Sandy soils drain quickly on their own, but water remains in lateral lines, valves, and heads until it is blown out. Any water left in the system will expand, crack pipes, and damage heads over winter. We schedule fall winterizations throughout Zimmerman each season — call in September to secure your spot before the fall rush.
Commercial Irrigation
Zimmerman is primarily a residential community, and the commercial market here reflects that. The Highway 169 corridor carries the city's retail and service businesses. Zimmerman's city park system and athletic fields represent the most consistent commercial irrigation need in the area. Zimmerman Elementary and the school district facilities are additional accounts for seasonal service.
For commercial properties along the Hwy 169 corridor — businesses, professional offices, or any property with maintained grounds — we provide installation and full-service irrigation contracts. The growing residential base means more commercial support services arriving over time, and we are positioned to serve those accounts as the community continues to build out.
Request Commercial ServiceWhy Sunshine Sprinkler Systems
We have been installing and servicing irrigation systems in the west and northwest metro since the mid-1980s. Sandy Anoka Sand Plain soils, cycle-and-soak programming, and moderately hard well water are all familiar territory for our crew.
Jon personally designs every new installation. He measures your property, assesses slope and soil type, checks water pressure, and delivers a written quote on-site. For first-time system owners, this walk-through is part of what you are paying for.
Jon, his son Sam, and Jolene run this business. When you call, Jolene picks up. When we come to measure, it is Jon. When install day comes, it is Jon and Sam on your property — not a subcontracted crew.
More Google reviews than our local competitors. No franchise fees, no shortcuts. Every system is one we stand behind, and our track record in the Sherburne County market shows it.
Zimmerman has no standing seasonal irrigation restrictions. There is no mandatory odd/even schedule that begins May 1, no summer blackout window that applies every year. In a normal non-drought year, Zimmerman homeowners can irrigate on any schedule that makes sense for their lawn and soil type, with no city-imposed limitations.
When the city declares a drought emergency, restrictions activate. The schedule becomes odd/even by address and limits irrigation to the nighttime window: 8 p.m. to 8 a.m. only. Zimmerman strengthened its drought enforcement ordinance in 2021 after a period of violations during a previous drought declaration. The city modeled its updated ordinance after Andover's regulations. Fines apply for violations once restrictions are in effect.
A smart WaterSense controller handles drought compliance automatically. When restrictions are active and the allowed window is 8 p.m.–8 a.m., the controller runs only within that window. The weather sensor skips cycles on rainy nights, so the system is not watering when drought restrictions are most likely to be scrutinized. Zimmerman is not in the Met Council seven-county area, so no rebate program is available for controller upgrades — but the efficiency savings are real regardless.
