Construction Site and Wastewater Management
The City wants to better understand the needs of industry partners when it comes to the Construction Dewatering Program. This program will help protect the environment by mitigating flooding & enforcing water quality requirements established by the By-law and provide a clear process for submitting a permit application.
The City of Hamilton Sewer Use By-law No. 14-090 requires City-issued permits for wastewater discharges that fall outside of the Sewer Use By-law standard terms and conditions. The Construction Dewatering Sewer Discharge Permit is designed for dewatering discharges from construction, land development, renovation, repair, maintenance or demolition activities. The Construction Dewatering Sewer Discharge Permit is required prior to the start of dewatering.
The purpose of the Construction Dewatering Program is to:
- Ensure the City can successfully manage the conveyance sewer infrastructure and associated water quality treatment systems required to support construction dewatering activities from development projects.
- Ensure capacity in the stormwater, sanitary and combined sewer systems, and receiving Woodward Avenue Wastewater Treatment Plant (WWTP) and at the Dundas WWTP.
- Abate potential risks of backups in the City’s conveyance system causing overflow events and associated damages
- Help protect the environment by mitigating flooding and enforcing water quality requirements as established by the Sewer Use By-law and provide developers with a clear process for submitting a permit application.
- Recover the costs associated with administering and monitoring construction dewatering discharges
- Recover the cost of treatment (for discharges to the sanitary or combined sewer system).
