Ville de Laval launched its gutter disconnection programme in 2014, which is based on
Bylaw L-11870 (PDF, 6.5 MB) and is intended to upgrade gutter connection standards.
An issue with non-compliant rainwater gutters exists, specifically in sectors with pitched roofs.
Since 2014, inspections have been carried out in the Auteuil, Vimont, Laval-West, Chomedey, Sainte-Rose, Fabreville, Laval-des-Rapides, Pont-Viau, Duvernay and St-Vincent-de-Paul sectors.
In 2019, Laval plans to conduct an initial inspection of rainwater gutters in homes located in the neighbourhoods shown on the following maps:
Auteuil ─ between the rainway and Terrasse Coutu, 3,59 Mb (French only)
Duvernay ─ between rue des Hiboux and Place Berthelot, 1,80 Mb (French only)
Saint-François ─ between rue Rondeau and rue Guindon, 1,60 Mb (French only)
Saint-Vincent-de-Paul and Duvernay ─ between avenue Breault and rue St-Jean, 2,81 Mb (French only)
Sainte-Rose, 4,21 Mb (French only)
The importance of properly connected gutters
Gutters that directly or indirectly empty out into the municipal sewage system constitute a threat to your property, they overburden the water purification plants and they contribute to the deterioration of the water of our rivers.

The visit from the City representative
The objective of the gutter disconnection programme is to encourage best rainwater management practices.
The first step consists of ascertaining the gutters' current condition. In that respect, this summer, properly identified Ville de Laval representatives will be patrolling streets to check and to document each home gutter connection for the areas shown in the plans.
A second visit will be carried out this summer in areas that have already been inspected once, in order to evaluate the effect of the actions taken by the citizens.
Your presence is not mandatory during the representative's inspection, as it is carried out from outside of your home. Please note that some gutters may be photographed in order to document the visit.
Three common examples of non-compliant gutters
Connection to the foundation drain (or French drain)
Emptying out directly onto the street
Emptying the water onto an impermeable surface which is slanted towards the streetéversement de l'eau sur une surface imperméable inclinée vers la rue
Gutter disconnection is one of the most effective techniques.
Before disconnecting your gutters wait for the city visit report summary.
Stages of disconnection of non-compliant gutters
One good practice consists of channeling the water coming from the roof and from paved surfaces, towards permeable areas.
Ville de Laval would like to first and foremost emphasise the positive effects of gutter disconnection and urges citizens to comply with Civil Code clauses 976, 979 and 983 regarding their neighbourhoods. Particular attention should also be paid during correction work so as not to direct the water to a neighbouring properties.
