Existing soils failed hydraulic conductivity requirements for cell expansion, prompting the converstion of a landfill to a transfer station.

A rural municipality was proposing to expand their current Class 3 Waste Disposal Ground as well as implement a Waste Trasnfer Site. However, geotechnical investigations concluded the native soils did not meet the minimum hydraulic conductivity requirements for cell expansion. BMCE completed a feasibility study and class D cost opinion to assess the costs and practicality of active cell expansion in conjunction with a waste trasnfer site. It was determined that transferring all of the waste was the most economical solution due to initial capital costs.

In accordance with environmental guidelines, BMCE completed a topographical site survey to generate an existing site plan and assess existing drainage patterns. Geotechnical investigations were completed to determine soil stratigraphy; monitoring wells were also installed so that ground water depth and water chemistry could be obtained. Considerations for the movement of large trucks and ease of traffic flow were made in the design of the site. BMCE provided construction administration services inlcuding tendering, project management, resident engineering and final approvals.

The municipality continues to boast the simplicity and seemless design of their new trasnfer station, it is often used as an example to surrounding communities to demonstrate the benefits of conversion to a transfer station.
