Outdoor Water Use Restrictions

 

Outdoor water use

During extended periods of hot, dry weather, water demand can increase by up to 50% largely due to outdoor water use. However, there are limits to the volume of water Halton is allowed to draw from our water sources, and to the capacity of the water treatment and distribution system.

If necessary, outdoor water use restrictions may be put in place to ensure there is enough water for:

  • essential use
  • emergency firefighting use

Water restrictions

If necessary, Halton Region may issue a change in outdoor water use restrictions. The criteria used for changing restriction levels include:

  • Volume of water treated
  • Water reservoir levels
  • Permits to Take Water
  • Well field aquifer levels
  • Long and short term weather patterns

Current water restriction level

Restriction Level

Level 1 - Careful use

Details

  • No serious shortage at this level.
  • Voluntary reduction of outdoor water use.

When to water your lawn: odd/even lawn watering

To balance peak water demand, Halton Region asks residents and businesses to water lawns according to the odd/even rule:

  • If your address number ends in an odd number, water your lawn on an odd calendar day.
  • If your address number ends in an even number, water your lawn on an even calendar day.

You do not need to water the lawn on every odd or even day. Watering deeply once or twice a week helps encourage deeper root growth, and a stronger, healthier lawn, better able to withstand periods of drought.
