The city government thinks it can finally kill the stench coming from a stormwater pond in Riverside South.
The pond between Dusty Miller Crescent and Limebank Road stinks. The sulphur smell has made the area reek like rotten eggs in the winter. It’s been on city hall’s radar for years, but it hasn’t been able to stop the stench. Construction of new stormwater ponds in the community have made residents nervous.
But now, a $150,000 solution for the stinky pond is in the works and it could finally clear the air in this corner of the southern suburb. City staff brought in researchers from the University of Ottawa, and together, they believe they have come up with an answer.
The pond stinks because of the hydrogen sulfide gas produced by naturally occurring bacteria. Researchers have suggested increasing dissolved oxygen levels by installing an aeration system at the pond. The stench has been particularly terrible in the winter months when the pond freezes over, lowering the oxygen level and allowing the bacteria to grow.
In 2012, the city paid $30,000 to increase the dissolved oxygen with an electromagnetic instrument. The city couldn’t tell if the device actually eliminated the odour, so that idea was scrapped. Draining the pond became the only solution to removing the stench.
The city has preliminary plans to build a mechanical pump aeration system, according to information provided to the community by Gloucester-South Nepean Coun. Michael Qaqish.
The city would have to build a precast concrete building beside the pond and run an electrical supply from Limebank Road. The building would have an air blower and control panel. The bottom of the pond would be outfitted with eight aeration units that release air bubbles into the water.
“After years of rotten egg odours emitting from the pond, I believe we have a permanent solution to the problem,” Qaqish said. “Once implemented, residents can enjoy more pleasant walks along its pathways and the neighbouring park.”
The city plans to start construction in July or August and finish before next winter. Some of the pathways around the pond will have to close during construction. The city doesn’t expect there to be noise issues with the anti-stink measures since the components of the aeration system will be enclosed.
