Water resources

Climate change causes heavier rainfall that must be managed, removed, and filtered intelligently and strategically to protect our communities. By implementing viable solutions, the engineering sector provides stormwater management that significantly minimizes the risk of flooding and landslides to ensure the safety of the public and the integrity of private property and public infrastructure.



A team of specialists

Every day, cities face many stormwater management related challenges: combined sewer overflows, increased stormwater frequency and intensity, aging or undersized stormwater systems and basement flooding are just a few.

Our team of stormwater management experts apply strategies and measures that can adapt to urban growth and densification to limit the impact on their systems. We can manage infrastructure assets to determine their life expectancy and the best way to upgrade them to meet your long-term growth plans. Our experts can also assist municipal clients with the development and retrofit of their stormwater management systems.
