Safe Water Program - Recreational Water

Water testing

Halton Region wants to keep its residents safe and part of that commitment is preventing and reducing water-borne illness and injury related to recreational water use.

Public recreational water facilities are regulated under 2 categories:

  1. Regulated facilities, including public pools and public spas.
  2. Non-regulated facilities, including public wading pools, splash pads/spray pads, and water slide receiving basins.

Public Health Inspectors inspect recreational water facilities to monitor the safety of these facilities. Public Health Inspectors also monitor water quality at
some of Halton’s public beaches.

Submit Notification to Open Pool or Spa

Pool/spa operators must notify the Health Department if they are planning to open or reopen a pool/spa.
