The Context
Materials and know-how for the compliant management of stormwater
Municipal regulation aims to restrict the flow of storm water from private land to prevent overloading of sewers. In addition, the client was aware of the new provincial regulations requiring that storm water be captured for transport to a wastewater treatment plant, subsequent treatment (optimal sediment removal) and storage with a view to re-infiltration. As a private investor, he was concerned about the cost of infrastructure.
