PFSV Educational Series - Part 1

Aug 26, 2014

Over the coming months, the Pritchard Farms Southlands Village (PFSV) blog will present an educational series on the PFSV Southlands Creek.  This month’s topic is the stormwater retention basin (SRB).

Stormwater Retention Basin

While Southlands Creek is a SRB, Qualico Communities has retrofitted it by adding natural wetland material and plantings.  You may be wondering, what is the difference?   A SRB is designed to hold a specific amount of water indefinitely.  Southlands Creek accepts water and through the land drainage system it slowly discharges water after rain events until a normal water level is achieved. A wetland is nature’s water purifier and acts as a filter by removing sediment and other pollutants from stormwater, filters decomposing vegetation, and recycles nutrients.

Many of the pollutants that come in with runoff are then exposed to sunlight and naturally broken down into less harmful elements.  Aquatic plants, such as cattails, also use excess nutrients, such as nitrogen and phosphorous, for their own growth and are passed on to future generations as these plant communities continue to grow.  The waters in the pond and those that flow outward are in a much cleaner state due to the SRB’s ability to permanently remove excess pollutants.

The soil is usually dark brown in colour due to the presence of mineral and organic matter, but why does it smell?  It’s because hydrogen sulfide is produced in the process.  Wetlands do much more good than harm and that odour means the ecosystem is thriving.  So next time you catch a whiff of hydrogen sulfide in your area remember, it may smell bad, but it’s really all good.

Although a SRB can never replace all the functions and attributes of a natural wetland, the wetland science applied makes PFSV a much better community to live in.
