Yorkton to pipe leachate from landfill to treatment plant

The project was submitted as a capital budget request in 2022, which was approved for $565,000.

YORKTON - A project to get leachate water from the city landfill to the city’s sewage treatment plant will move ahead after Yorkton Council approved a project tender Monday.

The need for a pipeline was outlined by Aron Hershmiller, Director of Public Works with the city at the regular meeting of Council.

The City of Yorkton's new landfill cell has been operational since the fall of 2022, he explained.

The landfill cell in lined so within the new cell, any precipitation that falls (snowmelt/rain) must make its way through the refuse material and into a collection system which is then pumped into the leachate collection cell, explained Hershmiller.

The leachate cell holds the leachate water until it is able to be treated or until it evaporates.

Dealing with this excess leachate has very limited options.

Most sites either truck this liquid for treatment or use a pipeline to a wastewater treatment facility. This project is a proactive plan that will serve us once completed and for future years, said Hershmiller.

Yorkton is opting not to use trucks.

The project will consist of directional drilling / installing approximately 1,000 meters of 3 inch HDPE pipe from the leachate cell to the Wastewater Treatment Plant’s headworks manhole, said Hershmiller.

The leachate will then be treated at the plant.

Infrastructure such as a concrete access vault, pumps, valves, flow meter and controls in addition to the work required to tie into the Wastewater Treatment Plant is all included in this project. Pipeline alignment and provisions will be made in order to easily tie into the future new/upgraded Wastewater Treatment Plant, he told Council.

The project was submitted as a capital budget request in 2022, which was approved for $565,000.

“The project was approved by Council and is one of the many capital projects planned in the city for 2024,” said Hershmiller.

Two tenders were received, the lowest from Triple A Directional Drilling Ltd., for $358,562 plus taxes. With taxes, contingency, electrical and engineering services, the total projected cost is $525,242, an amount approved unanimously by Council.
