How to Use This Calculator
  1. Enter Splash pad area (sq ft), Peak child capacity, and Water system.
  2. Set Operating hours/day and Season length (days).
  3. Review Recommended features and Construction cost ($) ($).
  4. Use Ground spray jets and Arch / curtain sprays to inform your decision.

What each input means

Splash pad area (sq ft)
Total spray pad surface area.
Peak child capacity
Maximum children using the splash pad at one time.
Water system
0 = Flow-through (drain to waste), 1 = Recirculating (filtered + treated).
Operating hours/day
Daily hours the splash pad runs.
Season length (days)
Number of operating days per year (e.g., Memorial Day to Labor Day ≈ 100-120).

What each result means

Recommended features
Total water play features (ground sprays, arches, interactives, centerpiece).
Ground spray jets
In-ground nozzles and jets.
Arch / curtain sprays
Overhead arches and water curtain features.
Design flow rate (GPM)
Total system flow rate with 20% safety margin.
Pump size (HP)
Recommended pump horsepower.
Daily water usage (gal)
Estimated daily water consumption.
Seasonal water cost ($)
Estimated water bill for the operating season.
Construction cost ($)
Total estimated construction cost (pad + features + mechanical).
Annual operating cost ($)
Water + electric + chemicals + maintenance per year.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Splash pad area (sq ft) = 1500, Peak child capacity = 30, Water system = 1, Operating hours/day = 8 = 5 input(s) provided
  2. Calculate Recommended features
    Recommended features
    20 = 20
  3. Calculate Construction cost
    Construction cost
    152500 = $152,500
  4. Calculate Ground spray jets
    Ground spray jets
    9 = 9
  5. Calculate Arch / curtain sprays
    Arch / curtain sprays
    4 = 4
