(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

SPS 382.33 (9) (k)
(k) Swimming pools. 1. The backwash and drain wastewater from a swimming pool, wading pool or whirlpool shall discharge 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.
4. The requirements for sewer connections as specified in ch. SPS 390 applies to all public swimming pools.
Note: An alternate system approval exists to allow backwash discharge via air break.
