RAIN is a RESOURCE

Reducing pollution in rivers, lakes and streams

MANITOBA ECO-NETWORK WATER CAUCUS is now part of GREEN COMMUNITIES CANADA’S RAIN program to address the impact on lakes and streams of stormwater runoff in urban areas. We are working with municipalities and homeowners to reduce run-off contamination by slowing stormwater flows and maximizing natural filtration.

Stormwater contamination is a growing concern

The proliferation of hard surfaces in our cities and towns means that falling rain has nowhere else to go than the storm sewer system.  Weather events generate large volumes of run-off, carrying pollutants from roads, parking lots, and lawns (e.g. pet waste) through storm sewers into local waterways. Contaminants threaten source water, wildlife, and recreational uses like swimming.

Run-off volumes can overwhelm the capacity of the engineered stormwater management systems, resulting in flooding and erosion, and in some cases combined sewer overflow results in untreated human wastes flowing directly into waterways. With climate change, an increase in severe weather events is expected.

Stormwater infrastructure is very costly, and budget-constrained municipalities find it difficult to keep up with the growing demand resulting from urban development.

Maximizing nature

The goal of RAIN is to maximize natural hydrologic processes through a variety of practical and positive solutions like rain water harvesting, porous paving, dog waste composters, and rain gardens. Measures like these can divert thousands of litres of polluted stormwater from entering the system. Diverted rain is then filtered naturally by the soil and recharges our precious groundwater aquifers.
