The town of Banff
The Town of Banff decided to expand and upgrade their existing Wastewater Treatment Plant (WWTP), through the use of the Design/Build/Operate (DBO) project delivery model. The DBO project delivery model presented a unique opportunity for the Town of Banff to truly find the most efficient process to meet its needs. In order to be successful the proponent needed to select the most effective design based on both the capital as well as the long-term operational costs. The DBO team included Earth Tech (Canada), Maple Reinders (Canada) and Christiaens Group (NL). The tunnel composting system utilizes aerated static pile technology, and is based on a process-control system developed by the Christiaens Group. The control system allows a high level of control over all phases of the composting system and requires little operator attention over the 21-day composting cycle.
