Development Of A Feasibility Framework For Trickle Fill Water Distribution Projects
Abstract
Lacking economies of scale, most Canadian small water systems do not have the financial capability to maintain sustainable operations, resulting in hundreds of drinking water advisories every year. In Alberta, an alternative to small rural systems has been emerging due to government investment in regionalization. With the “trickle fill” option, treated water is provided from regional supplies via small-diameter piping. This study outlines a feasibility assessment framework for trickle fill regionalization and conducts a case study for an area in Rocky View, Alberta. The case study develops a concept design and calculates the corresponding average end-user cost to be $165.03/month/home with ~80% of the cost due to regional system owner rates. While the study finds that the option is more sustainable than existing systems in the case area, either subsidies or a reduction in connection fees would be required to make it affordable for homeowners.
