Watertown, South Dakota, sits in Codington County and experiences a humid continental climate with cold winters and warm, moderately humid summers. The growing season typically runs from late April to early October, giving homeowners and commercial properties a clear window for lawn and landscape irrigation. The local market is driven by residential lawns, golf courses such as the Watertown Municipal Golf Course, and agricultural operations in the surrounding farming community. Many older homes still use manual watering or outdated sprinkler systems, creating strong demand for both new installations and system upgrades. Competition includes a few established plumbing and landscape companies, but specialized irrigation contractors are less common. With increasing awareness of water conservation and smart irrigation technology, a new business can capture market share by emphasizing modern, efficient systems. The proximity to Lake Kampeska and several recreational areas also means that lakeside properties often require irrigation for turf and gardens.
South Dakota does not have a statewide contractor license for irrigation systems, but you may need a plumber’s license if your work involves connecting to a potable water supply. The South Dakota Department of Labor and Regulation handles licensing. For most irrigation installations, a plumber’s license is not required as long as you install a backflow prevention device certified by a licensed backflow tester. However, it is prudent to hold a general contractor license for projects above $10,000 in value, which is available through the South Dakota Contractors Registration Program.
Watertown follows the South Dakota Department of Environment and Natural Resources rules on cross-connection control. You must use an approved backflow prevention assembly and have it tested annually by a certified backflow tester. Many irrigation contractors get their own backflow tester certification to offer this service in-house.
You need a City of Watertown business license. Apply at the City Finance Office, providing proof of liability insurance and Workers’ Compensation coverage. Pulling permits for underground sprinkler systems is required; inspections are performed by the Watertown Building and Inspections Department. Additionally, if you use any groundwater from a well, you must register with the South Dakota Department of Agriculture and Natural Resources.
General liability insurance ($1 million minimum) and commercial auto insurance are essential. Workers’ compensation is mandatory if you hire employees. Consider bonding to reassure clients in case of incomplete work.

Pricing in Watertown is moderate compared to larger metros in South Dakota like Sioux Falls. Below are typical ranges based on local data:
Charge by the job rather than hourly for transparency. Offer bundle packages (spring startup + summer checkup + winterization) for $250–$350 to encourage repeat business. Competitive rates in Watertown should be 10–15% lower than Sioux Falls but slightly higher than rural areas like Milbank or Brookings.
