RainWise rebate program

Apply for a stormwater rebate through the RainWise Rebate Program for projects that can help reduce the risk of your property flooding during a major rainstorm event.

Program overview

The RainWise Rebate Program is a three-year pilot program that makes it easier and more affordable for Edmonton residents to protect their properties from flooding and reduce flood risk in the community through effective stormwater management.

If you are a property owner or renter in Edmonton, you are eligible for rebates from EPCOR on projects that help manage stormwater on your property.

Rebates are available for projects that help to:

Reduce the quantity of stormwater entering the collection system.
Improve the quality of stormwater released into the collection system.
Prevent overland runoff and sewage from entering homes and businesses.

How to apply

Follow these three simple steps to get your rebate

Step 1: Get approved

Before you move forward with any work, make sure your project is approved through the RainWise Rebate program.

The RainWise rebate program is not retroactive. Projects completed before the application is approved are not eligible for the rebates.
Make sure your project meets our rebate requirements by reading through the specific project details page.
Submit your application form and view guidelines for filling it out.
After you submit your application, it may take up to 10 business days to hear if your project has been approved.

Step 2: Complete your project

Complete your project by yourself or hire a contractor (EPCOR reserves the right to require professional design/construction when projects are considered to be advanced. Examples include rain barrel/storage tank below or above grade (≥ 2.0 m) or modular underground storage for MF and ICI applications).
Keep all receipts.
Complete your project within one (1) year of the application approval date to remain eligible for the rebate.

Step 3: Submit for reimbursement

Ensure you have all necessary photos and documentation (e.g. receipts) so your claim can be processed efficiently and accurately.
After you submit your claim form, it may take up to 10 business days to hear if your claim has been approved. View guidelines for filling out your form.

The end of a white downspout releasing water into an area of soil surrounded by dense plants and ground vegetation. The downspout rests on a small concrete splash pad, with leaves, stems, and natural debris visible around the drainage point.

Downspout disconnectionsDetach your downspout from the standpipe that directs stormwater to the drainage system.

Project details

A brown rain barrel positioned beside a house and connected directly to a downspout to capture roof runoff. It sits along a concrete walkway next to garden plants, illustrating a typical residential setup for harvesting and storing rainwater.

Rain barrels and storage tanksA rain barrel/storage tank is a container, often connected to a downspout, that collects and stores rainwater from a roof.

Project details

Vibrant residential rain garden filled with layered ornamental grasses, flowering perennials, shrubs, and small trees. The naturalized planting design supports stormwater absorption while enhancing the home’s curb appeal with rich textures and colours.

Rain gardens and box plantersThese gardens with specially blended soils are designed to collect stormwater runoff.

Project details

Permeable pavementPermeable pavement/pavers are specially designed hard surfaces that allow water to soak into the ground.

Project details

Absorbent landscaping*Landscaping that looks similar to grassed areas and can include other plants and trees.

Project details

Soil cells*Soil cells are plastic milk crate-like structures, which are filled with loose, specially blended soil, designed to be installed beneath hardscape surfaces.

Project details

Soakaway pitsSoakaway pits are holes typically filled with rocks or gravel that let water gradually seep into the ground.

Project details

RainWise projects marked with an * are for multi-family and industrial, commercial, or institutional customers only.

Why is flood resiliency important?

Future changes in Edmonton’s climate could lead to increased instances of heavy rainfall and increase risk of flooding. This rainwater can be referred to as stormwater which also includes water from melting snow and hail. Stormwater runoff is the portion of this water that is not absorbed into the ground and goes into the stormwater and combined sewer systems.

One way to slow the entry of stormwater into the drainage system is through green infrastructure, which includes low impact development (LID). LID is a site development technique that aims to mimic natural processes to manage stormwater runoff close to its source. Examples of LID features include rain gardens, bioretention basins, box planters, soil cells, and absorbent landscaping. LID technique’s manage rainfall in ways similar to nature.
