						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).
5. 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.
6. 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.
Note:
The Department maintains a list on the
						Division of Industry Services Web page at
http://dsps.wi.gov/programs/industry-services
that is subject to change.

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

						in accordance with Table 382.38-1.
2. The discharge from deck drains serving indoor pools
						shall be directed to the sanitary sewer via an air-gap.
3. The discharge from deck drains serving outdoor pools
						shall be directed to the storm sewer by way of an air-gap or to grade.
