Watering and Water Usage

By-law (in French only)

Drinking water by-law CO-2008-536

As drinking water is a precious resource, Ville de Longueuil adopted a new by-law for its entire territory to promote a better use and management of drinking water.

The following summarizes the by-law's main provisions and does not replace the official text of the by-law passed by the city's council. For legal purposes, please refer to by-law CO-2008-536's official text.

Main provisions:

With a special permit, watering new lawns is permitted at all times except between 5:00 p.m. and 7:00 p.m. The permit, available for $20, is valid for 15 days and is not renewable.

Filling swimming pools

Filling swimming pools is prohibited between 5:00 p.m. and 7:00 p.m. It is also prohibited to fill a swimming pool with a hose having a diameter of over 2 cm.

For pools having a volume of over 9000 litres, citizens may use a hose whose diameter exceeds 2 cm, but a $20 permit is required. The permit is valid for 4 days and is not renewable.

A maximum of two permits can be issued the same year for the same building.

Car washing

Car washing is permitted with a hose with a water spray gun or with an automatic shutoff valve.

Fire hydrants

The use of watermains, fire hydrants, valves or other components of the water supply system is prohibited without a permit issued by the city. A fee of $100 for the first 5 days and $20 for each additional day applies.

Permits

For any information about permits, please visit one of our tax counters.

Other regulations

There are other regulations also designed to prevent wasting drinking water. For instance, it is prohibited to use drinking water to clean driveways, sidewalks and patios, to operate fountains and artificial waterfalls and basins without a recirculating pump, or to use a refrigeration or air conditioning unit requiring drinking water.

Infractions and penalties

In the summer, a team patrols the city's neighbourhoods to make sure that the regulations are complied with. Notices are issued to raise awareness about the regulations as needed. These notices are compiled in a computerized database.

Anyone who contravenes a regulation commits and infraction and is liable to a fine and costs.

If the infraction continues, it is considered as an infraction for every day it continues.

Municipal sewer and water systems

Sewer system

Sewer back up

If your sewer backs up, first try to locate the obstruction. We suggest that you contact your neighbours to see if they have the same problem. If such is the case, the problem is most likely due to the watermain in your street, therefore on public property, and you should immediately call the Service des travaux publics (public works), which will send a team to fix the problem.

However, if your neighbours don't have the same problem, the problem is usually on your property, in which case you should call a plumber.

Manhole covers

The manholes located along street curbs collect stormwater.

If you notice a manhole that is damaged or moved, please call the Service des travaux publics (public works) immediately. Also, the openings of a manhole grate must run perpendicular to the curb or sidewalk to prevent bicycle wheels from catching in the openings.

Water supply system

Rusty water

The quality of the drinking water we get from our faucets is excellent since it was first treated by the regional water treatment plant.

If the water from you tap has an unusual or rusty colour, it is usually due one of the following:

  • Cold water: presence of deposits in the watermains. To remedy this situation, the borough drains the watermains in the affected sector.
  • Hot water: it may be due to your hot water tank. We suggest that you drain your hot water tank with the valve at the bottom of the tank, following the manufacturer's instructions located on the tank. If the problem persists after draining, we suggest that you call a plumber.

Water pressure

A loss of pressure is usually due to defective plumbing or a break in the municipality's watermain.

If you have a water pressure drop, please contact the Service des travaux publics (public works) and the borough will send an employee as quickly as possible to determine the cause of the pressure drop. If the problem is due to municipal lines, the borough will immediately perform the work required to fix the problem.

However, if the problem is in your own plumbing system, the borough's employee can provide you with useful tips before your plumber arrives.
