It's unlikely the biofilter system designed to combat the stink at Lunenburg's wastewater treatment plant will be finished by a Halloween deadline, but that doesn't scare local civic politicians who've been told the project is going to be completed in the weeks ahead.

The $1.1 million procurement, awarded earlier this year to Annapolis County-based Mid Valley Construction, involves the supply and installation of a fan, ductwork, biofilter bed and associated electrical and mechanical work focused on the Starr Street facility.

The biofilter system is expected to resolve odour issues from the plant, which have been the subject of public complaints especially during the warmer weather. "We're very happy this project is soon going to be finished and working," Rachel Bailey told LighthouseNOW during a break at town council's October 23 meeting.

Issues with the Canadian equipment supplier, which custom-ordered many of the components south-of-the-border, "led to delays getting shop drawings approved and then further delays with equipment manufacturing," Lunenburg's town engineer Jamie Burgess said during the council meeting. "There has also been shipping delays caused by issues with customs."

Burgess said the major components have arrived, although there could be challenges with some of the small pipe fittings. Tests of the system are expected in late October and Burgess anticipates the project will be finished before December.

Two-thirds of the funding for the odour control system project comes from a combination of federal and provincial governments with Lunenburg picking up the remainder of the bill.

Lunenburg also paid a Halifax engineering firm, CBCL, to supervise construction and oversee the geotechnical work. The firm determined the main sources of the odours are situated inside the main plant, the dewatered sludge bin room and the aeration building. Town officials have consistently maintained the plant operates within its design capacity and meets federal and provincial treatment test standards as verified by independent and accredited labs.
