Liquids (rain/melted snow) that pass through a material is called leachate. Landfill leachate contains a wide range of organic and non-organic material, while organics wastewater contains mainly biodegradable material. If not properly managed, these materials could pose risk to the natural habitat of the surrounding environment.
Landfill leachate generated at the former Sackville Landfill (Highway 101) has been treated at an onsite facility for over 30 years. Organics wastewater from the two municipal compost facilities (Burnside and Goodwood) is collected and transported out of province for treatment.
The current proposal is to treat organics wastewater from these compost facilities at the Sackville Landfill Leachate Treatment Plant, which is operating well under capacity.
A 2011 review conducted by CBCL consultants determined that the leachate treatment facility at the Highway 101 site is more than capable of processing compost facility organics wastewater. Nova Scotia Environment has indicated that following public consultation and Regional Council approval, a permit to receive organics wastewater from the two municipal compost facilities would be obtainable. This change in practice could see savings in the hundreds of thousands of dollars.
The business case for this proposal was endorsed by Regional Council on September 10, 2013 (Item 11.2).
The Municipality will be hosting two public meetings to present this information to the community and allow for questions. Please note the following CHANGE of LOCATION & TIME for the second public meeting:
Monday, September 22 – 6:30 p.m.
Please note that the old landfill site in Sackville is not being reopened. There is more than enough plant capacity to deal with the small amount of organics wastewater to be processed. The addition of organics wastewater will not change the outflow quality. Outflow is strictly monitored to ensure it remains within water quality guidelines set by the Canadian Council of Ministers of the Environment (CCME) and adheres to provincial requirements.
Also, making use of available capacity at a municipal facility gives Halifax more control over the treatment of organics wastewater generated from our own operations and reduces reliance on third-party operated sites.
