With the withdrawal of the 2.5million grant for leachate treatment the Council has the opportunity to consider new options that might be more effective and less toxic to the environment than running a forcemain from the landfill site, along Grey Rd 13, Grey Rd 40, Grey Rd 2 to Clark Street to the sewage treatment plant
Kincardine's new leachate treatment plant up and running

The leachate treatment plant is up and running at the Kincardine Waste Management Centre in Armow.
The $1.7-million facility was officially opened in the fall, as municipal councillors and staff, along with members of the media, took a tour of the plant, courtesy of Shamus Anderson, water and wastewater supervisor.
Drawing leachate from the landfill site, the plant uses a biological process to treat up to 55,000 litres per day. The process basically converts the contaminants into solids which are settled out of the liquid. That liquid is then discharged into a stormwater pond where it is further filtered naturally and then, eventually, works its way into the North Penetangore River and to the lake. The sludge and solids are dumped into the landfill site.
Anderson said this state-of-the-art treatment facility is the only one of its kind in Bruce County. It replaces the trucking of leachate from the landfill site to the sewer lagoons in the Town of Kincardine, which had become a costly process.
“This is far more effective and efficient,” said Anderson.
The process mixes methanol, phosphoric acid and aluminum sulphate with the leachate to settle the solids and clear off the liquid. It's not a pleasant facility to stand around in as the odour can be quite pungent. However, once you move from the mixing chambers to the clarifying tank and into the office, the air is clearer.
Anderson has six operators who can work in this facility. The plant is operated through a computerized system that monitors all the inputs and outputs and provides data reports every day. If there is a problem, an alarm will sound, and steps are taken to rectify the situation.
Kincardine mayor Anne Eadie thanked the staff for the hard work in getting this facility up and running.
“With this plant in operation, the municipality has less risk, less cost and it's more environmentally-friendly,” she said, adding that the project was completed with the assistance of a federal government Economic Action Plan grant.
Three years after the Municipality of Kincardine began looking at options for dealing with leachate from two landfills it is now operating a state-of-the-art leachate treatment facility.
Municipal staff and Mayor Anne Eadie were on hand last Tuesday for a tour of the new facility at the waste management centre in Armow. Back in 2013, Kincardine council sought input from consultants at Conestoga Rovers and Associates on options to handle leachate – water that comes in contact with landfill waste. The municipality had been trucking upwards of 45,000 litres of leachate each day from the waste management centre and the now closed Ward 1 landfill site to the municipal wastewater treatment plant. However, the wastewater treatment plant was not designed to treat leachate and trucking the waste is costly.
The municipality required a long-term solution, given the fact that leachate is produced for as many as 50 years after a landfill closes. It determined that a treatment facility on site at the waste management centre made the most economical sense and would be a better solution from an environmental standpoint. The municipality used government gas tax rebates to construct the $1.7 million facility.
Pipes run from the landfill cells at the waste management centre to the facility where any solids are removed and the leachate is treated with menthol, phosphoric acid and aluminum sulphate to remove nitrates and phosphates. The entire process is computerized, requiring only one trained operator to be onsite for monitoring purposes.
Water and wastewater supervisor Shamus Anderson said the treatment of leachate at the new facility is subject to provincial regulations and sampling is conducted at several stages throughout the process, not only within the facility but in wetlands before discharged treated water reaches the Penetangore River. He said processing the leachate at the facility is the safest way to get rid of it, far more so than trucking it.
Eadie said she is pleased that the facility is finally up and running.
“It’s more cost effective and better environmentally.”
