Why these restrictions exist in Waterloo Region
The Region of Waterloo enforces annual outdoor water use restrictions from May 31 to September 30 each year. During this period, lawn watering with a sprinkler is limited to once per week on your assigned day. Assigned days are based on the last digit of your address: odd addresses water on odd-numbered dates, even addresses on even-numbered dates. Watering hours: 5:30–10:00 AM and/or 7:00–11:00 PM. Watering with a watering can, bucket, or rain barrel is allowed at any time. Gardens, trees, shrubs, and other outdoor plants can be watered every other day using a hose connected to municipal supply during the same hours. The region does not issue warnings before laying charges — bylaw enforcement officers may charge on first observation. Temporary 14-day watering permits are available for new sod, grass seed, or nematode application (one per property per year, applications open early May). This applies to Kitchener, Waterloo, Cambridge, Woolwich, Wellesley, Wilmot, North Dumfries, and all other Region of Waterloo municipalities. Vehicle washing with a hose must be on your assigned day. Commercial car washes are unrestricted. Complete pool filling is unrestricted; top-ups follow the schedule.
How to keep your Waterloo Region lawn alive
9 tips for Waterloo Region homeowners.
Identify your assigned date parity first — odd-numbered addresses water on odd-numbered calendar days; even on even.
Set sprinklers to deliver a deep 25 mm in a single session within the 5:30–10:00 AM or 7:00–11:00 PM windows — deep infrequent watering builds drought-tolerant roots.
Mow at 75–90 mm during summer; Kitchener-Waterloo's Kentucky Bluegrass lawns shade the soil better at higher cuts.
Apply for a 14-day exemption permit if installing new sod or grass seed in May — applications open in early May, one per property per year.
Use a rain gauge — Waterloo Region averages 75 mm of rain in May, June, and July; skip your assigned day after any 10 mm+ rainfall.
Install a rain barrel — captured rainwater is unrestricted and may be used any day, any time.
Hand watering of gardens, trees, and shrubs is permitted every other day with a hose during the same morning/evening hours — prioritise food crops and mature trees.
Apply 50–75 mm of mulch around shrub beds to retain moisture between weekly waterings.
Monitor regionofwaterloo.ca/water-conservation through summer — Level 1 (voluntary) and Level 2 (mandatory deeper cut) escalations layer on top of the annual schedule in dry years.
