Maintenance window
Definition
A regularly scheduled recurring time block — often Tuesday mornings or the first Monday of the month — when the splash pad is closed for filter backwash, sensor calibration, and routine inspection.
Maintenance windows are different from emergency closures. They are planned, recurring, and posted on the park sign at the start of the season. A typical municipal splash pad has a 2–4 hour weekly window plus a longer monthly window for deeper service.
During the window, the pad runs through automated cleaning cycles, sensors are recalibrated against handheld test kits, and the operator visually inspects every nozzle, drain cover, and ADA path. Skipping maintenance windows is the #1 reason mid-season pads end up with extended unplanned closures.
