Municipal Consolidated Linear Infrastructure Environmental Compliance Approvals (CLI ECA)

Sanitary and Stormwater System Alterations

If you need to request an alteration to our sanitary or stormwater system, find the process and application below.

1. About the process

The Ministry of the Environment, Conservation and Parks (MECP) has approved and granted the Township the authority to approve certain Environmental compliance Approvals (ECAs) to the Consolidated Linear Infrastructure (CLI) under certain conditions. Township’s CLI-ECA approval process covers most alterations that meet the preauthorized MECP requirements for the entire municipal sewage collection system and stormwater management system owned and operated by the Township of Wilmot. Development projects no longer need to submit individual pipe-by-pipe MECP application for future alternations; even though will need to make sure they:

• are designed and constructed in accordance with the following MECP Design Criteria
• meet the requirements as defined in the CLI-ECAs (Sewer Collection and Stormwater management) 
• satisfy other provincial and municipal approved conditions:

If the project does not meet the MECP criteria for CLI-ECAs, you may also need to apply for an individual ECA from the MECP or submit an application for an CLI-ECA alteration with the Region of Waterloo

2. Types of Alterations

There are two types of alterations related to the Township’s CLI-ECA applications:

• Sanitary (sewage) collection system: all connected sewage collection works within the Township of Wilmot and owned and/or operated by the Township of Wilmot including pumping stations and pipes.
• Stormwater management system: all connected stormwater management works within the Township of Wilmot and owned and/or operated by the Township of Wilmot, including pipes, stormwater management facilities, and Low Impact Development (LID) infrastructure.

3. When to request an Alteration 

You need to request a CLI ECA alteration for the following types of projects:

• changing, replacing or extending sanitary sewers and storm sewers, including extensions into new residential developments
• changes that are on city-owned property that includes parks and community centers serving a single parcel of land
• adding new sewage pumping stations or changing existing sewage pumping stations
• adding new stormwater management facilities or changing existing facilities (examples: wet pond, infiltration basins, engineered wetlands, oil grit separators)
• adding new or changing existing equipment with emissions to air (examples: emergency power generators or venting for odor control) related to sanitary and storm sewers, sewage pumping stations and/or stormwater management facilities

If you have any questions or are unsure if your project will need CLI ECA alteration, send us an email (engineering@wilmot.ca).

4. When you don’t need to request an Alteration

You don’t need to apply for a CLI-ECA alteration for privately owned sewage works on industrial or commercial land.

For these projects, you may still need an individual ECA from the MECP or a building permit.
