Sewer Overflow Reduction Program Latest Infrastructure Improvement

When your goal is to be true to your town’s 135-year-old motto, ‘Let New Glasgow Flourish’, one of the first places you start is by rebuilding the infrastructure. And it’s not just a phrase; it’s a way of life and path of guidance for the mayor, town council and residents of this town.

The latest project focused on those ambitions is a Combined Sewer Overflow (CSO) program for the city of nearly 10,000 to remove storm water from its sanitary sewer system. The installation of new storm sewers for 12 streets and upgrading of 12 pumping stations will help remove the storm water from the sewer system and make the East River Environmental Control Centre operate more efficiently.

“We are upgrading our infrastructure at every chance we get because it’s important,” stated Barrie MacMillan, Mayor of New Glasgow. “We want to separate the storm water and we’re doing that at a couple of areas within the town. The major area being upgraded is a tidal estuary for salt and fresh water, and is the centerpiece of our riverfront revitalization. This combined sewer overflow reduction is a critical project for us on a number of levels.”

“Today, this is a prime concern for the majority of municipalities across North America” observed Tony Radoszewski, executive director of the Plastics Pipe Institute, Inc. (PPI), a non-profit trade association that promotes plastic pipe.

“In the past, rainwater flowed into the sanitary sewer system and was then treated. Extra storm water would, during times of a heavy rain, create an overflow. This Combined Sewer Overflow generally discharged into a nearby water body. With the latest EPA Phase II requirements in the United States and similar regulations approved by the Canadian Council of Ministers of the Environment in 2009, controlling and managing storm water runoff is imperative, not only for the good and welfare of people, but also to meet these new governmental standards,” Radoszewski continued. “New Glasgow has found the way. Their program is a cutting edge blueprint for successful storm water quality improvements that deliver to federal Canadian mandates requiring the reduction of combined sewer systems. Their example is a good one to lead the way for achieving broad reaching compliance.”

New Glasgow has seen the effects of weather pattern changes and experienced recently more severe storms. A few years ago the north coastal city was pounded by several 100-year storms, which resulted in flooding of the downtown area. Even the flow volume from smaller storms due to the combined sewer and storm water system would overload the treatment plant. It was in 2009 that the city decided to take a closer look at the causes and find a solution to its combined sewer system.
