Public swimming pool chemical and opening requirements are listed below. View information on residential swimming pools and spas.
Swimming pools / special purpose pools disinfectants
- Free chlorine residual: 1.0–10.0 ppm
- Calcium hypochlorite, sodium hypochlorite, chlorine gas
- Bromine: 2.0–20.0 ppm
Spas / whirlpools
- Free chlorine: 2.0–10.0 ppm
- Bromine: 4.0–20.0 ppm
When combined chlorine is 0.5 ppm or higher: superchlorinate
- Raise free chlorine residual to approximately 10 times the combined chlorine levels
- An approved pool shock chemical equivalent to superchlorination standards may be used if shown effective.
- Try to let pool chlorine residual naturally return to approved levels instead of using de-chlorination chemicals.
- All pool types: pH 7.2–7.8
- For best results:
- Chlorinated pools: pH 7.2–7.6
- Brominated pools: pH 7.5–7.8
- Minimum 50 ppm, maintain 80–120 ppm
- If bromine is used as a disinfectant: 100–120 ppm
- Chlorinated outdoor swimming pools and spas: not to exceed 100 ppm. Recommend 10-20 ppm
- Pools and spas: maximum 104 degrees F (28 degrees C)
Outdoor swimming pools, spas and indoor pools must pass city inspection. An inspection must also take place after any major maintenance procedures, including resurfacing. Call 952-939-8200 to schedule an inspection.
Please complete the following items prior to the inspection so the pool can be opened and a license can be issued:
- Ensure all outlets (except for unblockable drains) are equipped with covers that have been stamped by the manufacturer that state they are in compliance with ASME/ANSI standards; and that all covers and grates, including mounting rings, have been inspected to ensure that they have been properly installed and are not broken or loose.
- All required safety equipment must be accessible. This includes a life ring and a rope (1.5 times the pool width, but not more than 60 feet), and a minimum 12-foot fixed length shepherd’s crook or life pole for each 2,000 square feet of water surface. Signs stating “Emergency Use Only” must also be posted by all safety equipment.
- Ensure all pump room equipment is provided and operating properly. This includes pressure gauges, sight glasses, flow meters, thermometers and disinfectant feeders. The required pool turnover rate must also be met.
- Your pool test kit must be approved and can test “free chlorine” (0-10 ppm), combined chlorine, pH, alkalinity, and cyanurates (if used).
- All depth markers at the deep end, shallow end and sides of the pools are tiled or painted at least four inches in height and are a maximum of 25 feet apart using a minimum “ft” or “in” designation.
- In locations where diving is not allowed, you must post the words “No Diving” with the letters at least four inches in height, or a universal “no diving” symbol at least four inches in height with the words “No Diving” at least a half-inch in height. These must be in contrasting color at all ends and sides of the pool, spaced a maximum of 25 feet apart. This does not apply to spas or wading pool.
- Steps and ladders must have contrasting front edges tiled or painted at least 0.5–2 inches wide.
- A contrasting stripe at least six inches wide must be present on the pool sides and bottom between all slopes or transition lines. For example, between the shallow and deep ends of the pool.
- All fences and gates must be self-closing and self-latching, capable of being locked and not readily climbable. Fence openings can’t be wider than four inches, and no taller than two inches below the fence. Other requirements may apply (i.e. chain-link fences).
- All signage should include complete updated information, including bather load, rules and emergency signs.
- The first-aid kit and supplies must be accessible to pool users.
- Ensure the safety of all pool users by checking the overall structure and condition of the pool and pool equipment (smooth surfaces, no peeling paint, etc.).
- All pool water chemical levels must be within acceptable ranges.
- Label and identify all piping, including arrows showing directional flow.
- Ensure all pool equipment operational manuals are available.
- Post or provide proof of successful completion of a National Certified Pool Operator’s Course. This certificate must be revalidated every five years. Visit the Minnesota Department of Health’s website for a list of Certified Pool Operator (CPO) training courses.
- Please notify the city of all equipment changes or alterations to the pool such as changing the recirculation system (pump, piping and filter system). These changes may require submission of plans or obtaining permits from the city. All pool equipment must meet National Sanitation Foundation (N.S.F.) standards.
- Please review the previous inspections to ensure all corrections have been completed.
