The material contained in this appendix is for clarification purposes only. The notes, illustrations, etc., are numbered to correspond to the number of the rule as it appears in the text of the code.
A–390.03 (26) Plan submittal and fees. The following is a listing of when the department may waive submittal of pool plans and fees for the reconstruction and alteration of existing pools.
1. A disinfection system equipped with a positive displacement pump is replaced by an approved pass-through (erosion) type systema or vise versa, the replacement of a gas chlorine system with a positive displacement pump or approved pass-through feedera.
Note: The installation of a gas chlorine system will require plan submittal and a fee.
2. A circulation pump is replaced by another pump from a different manufacturer provided that the new pump is the same make and model or equivalenta.
3. A filter is replaced with an approved filter of the same make and model or equivalenta.
4. The replacement of metal piping and fittings with the same size PVC piping and fittings used to repair a small section of the circulation system (less than 10 feet).
A supplemental disinfecting systema
is installed (e.g., Ozone, Ultraviolet Light, etc.) provided that the halogen residual is maintained as stated in ch. ATCP 76
and that there is no decrease in the required water circulation flow rate.
For the installation of a slide 6-foot or less in height, a slide structural plan review in accordance with ch. SPS 361
is not required. Such slides shall meet the guidelines listed in Table 390.30–1.
7. Minor repair of basin or deck.
a All equipment under the scope of NSF 50 must be listed to comply with NSF 50.
A–390.05 (2) Authorized inspection agents. In addition to department staff, the department has authorized representatives to conduct inspections of construction or modification of any public swimming pool or water attraction that require approval under s. SPS 390.04. The cities of Madison, Milwaukee and Racine do inspections for those installations located within their jurisdiction.
A–390.11 (8) Measuring the transitional radius between the wall and floor of a basin in less than 5 feet of water.
A–390.11 (10) Design of the vanishing edge basin.
A–390.12 (3) Deck-mounted hand rail installations.
A–390.13 (5) Outdoor pool deck drain storm sewer connection.
A–390.14 (1) Turnover rate calculation for water slides.
Imaginary Plunge Pool (IPP) = 6,700 gallons that requires one turnover recirculation.
(15 ft C 20 ft C 3 ft = 900 cu ft = 6,700 gallons)
The concept of the imaginary plunge pool is applied to a single waterslide or runout slide that is associated with a pool and uses water from the associated pool for its operation. When more than one waterslide or runout slide is associated with a pool, each additional runout slide or waterslide contributes 4,500 gallons to the imaginary plunge pool quantity of water.
(10 ft C 20 ft C 3 ft = 600 cu ft = 4,500 gallons)
Calculation examples using the IPP concept:
1. Addition of one waterslide or runout slide to a 70,000 gallon pool
70,000 gal pool = 6,700 gal 1hr IPP + 63,300 gal 6hr pool
6,700 gal ÷ 60 min = 112 gpm recirculation
63,300 gal ÷ 360 min = 176 gpm recirculation
288 gpm total recirculation requirement
70,000 gal ÷ 288 gpm = 4 hr turnover for addition of one waterslide or runout slide
2. Addition of one waterslide or runout slide to a 170,000 gallon pool
170,000 gal pool = 6,700 gal 1hr IPP + 163,300 gal 6hr pool
6,700 gal ÷ 60 min = 112 gpm recirculation
163,300 gal ÷ 360 min = 454 gpm recirculation
566 gpm total recirculation requirement
170,000 gal ÷ 566 gpm = 5 hr turnover for addition of one waterslide or runout slide
3. Addition of two waterslides or runout slides to a 170,000 gallon pool
170,000 gal pool = 11,200 gal 1hr IPP + 158,800 gal 6hr pool
11,200 gal ÷ 60 min = 187 gpm recirculation
158,800 gal ÷ 360 min = 441 gpm recirculation
628 gpm total recirculation requirement
170,000 gal ÷ 628 gpm = 4.5 hr turnover for addition of one waterslide or runout slide

f For stormwater, the plumbing treatment standards are based on an annual average. Evaluation of research to prove compliance with this table is based on the geometric mean of the data acceptable to the department or an equivalent method.
