Why does the Region have a Program to monitor outdoor water use?

During the hot summer months, water consumption can increase by 50%.

Despite the increase in demand for water, there are limits to both the amount of potable water any given treatment plan can produce and the amount of water the Region is permitted to take from any given water source.

The Region may enforce outdoor water use restrictions to make sure there is enough water for emergency and essential services, such as firefighting and flushing the drinking water system.

What does the Program do?

The Outdoor Water Use Program monitors:

The Region's drinking water systems. Specifically, the amount of water being produced and delivered from the Water Purification Plants.
Source water levels.
Risk factors that strain our supply of potable water (i.e. weather patterns).

When certain indicators show that our water system is stressed the Region will issue a change in restriction level.

Depending on the current restriction level in effect, residents may be asked to reduce or stop outdoor water activities, until water levels are higher again.

How does the Region decide what level should be in effect?

Halton Region has a set of criteria for changing between levels.

The criteria includes:

Water production rates.
Daily reservoir levels.
Aquifer levels.
Weather patterns.

Regional staff monitor conditions on a daily basis. When preset levels for the different criteria are reached, the process of changing from one restriction level to another begins.
