Much of Canada's water service infrastructure is in need of replacement as this centralized infrastructure has reached its design life. Future water service options that improve upon economic, environmental and societal goals include separate collection and treatment of blackwater (toilet and kitchen food streams) from the remaining household grey water. The overall goal of the proposed research is to develop a robust bioreactor system with high biomethane production and low environmental risks for source-diverted blackwater energy recovery that suits the cold Canadian conditions. This research will focus on engineering a recently discovered metabolic pathway for methane production, known as direct interspecies electron transfer (DIET). The proposed research is expected to provide fundamental knowledge for developing technology with dramatic life-cycle cost and environmental health risk reductions and to facilitate sustainable urban water development.

加拿大的大部分供水服务基础设施需要更换，因为这种集中式基础设施已达到其设计寿命。未来的水服务选择，改善经济，环境和社会目标，包括分开收集和处理黑水（厕所和厨房食物流）从剩余的家庭灰水。拟议研究的总体目标是开发一个强大的生物反应器系统，具有高生物甲烷产量和低环境风险，用于适合加拿大寒冷条件的源头转移黑水能源回收。 这项研究将集中在工程最近发现的甲烷生产代谢途径，称为直接种间电子转移（DIET）。预计拟议的研究将为开发具有显著生命周期成本和环境健康风险降低的技术提供基本知识，并促进可持续的城市水资源开发。
