Description
The Town of St. Andrews will upgrade its 30-year-old wastewater treatment plant to meet and exceed current provincial and federal environmental standards, minimize its environmental impact, and eliminate a barrier to economic development.
The town will deepen one of its two wastewater treatment ponds, install a new clay liner and control structure, and convert it to an aerated pond. It will also introduce a submerged aeration system for both of its treatment ponds, add a UV disinfection system for tertiary treatment, replace pumps in its wastewater pumping station, and install a monitoring and control system. The new monitoring system will allow the town to quickly respond to problems and equipment failures and minimize the release of untreated effluent into the environment. The UV system will ensure that there is no residual chlorine in disinfected water released into the marine environment.
By upgrading existing facilities, rather than expanding onto adjacent lands, the town will be able to increase its wastewater treatment capacity while controlling costs and avoiding the environmental impact of extensive new construction. The upgrade is part of a broader, ongoing wastewater plan that includes separating the town’s storm sewer connections from its sanitary collection system and encouraging citizens to remove foundation drains from their sanitary sewer service lines. It is projected that for most of the year the Total Suspended Solids (TTS) will be reduced from a maximum of 30 to 3 mg/L, the five day Carbonaceous Oxygen Demand (CBOD5) will be reduced from a maximum of 20 to 3 mg/L, and the system will not require the use of chlorine.
The upgraded system will improve the quality of life in the town by reducing health risks, cutting noise pollution and minimizing offensive odours. Increased wastewater handling capacity will also open the door to more sustainable growth and make the town more environmentally friendly.
