Small Water Systems: Design Challenges and Opportunities to Meet Current Regulation

Description:There are numerous small water systems located in remote communities in BC, which are nearing the end of life on mechanical components and do not meet the current regulations. Small water systems generally have inadequate funding, but are required to provide high quality water analogous to larger systems. TerraVista and Akiskinook strata community are located in the East Kootenays and draw water from Lake Windermere. The systems were installed in the mid-1970s and only chlorination was provided for treatment. Interior Health Authority (IHA) has mandated that all water treatment suppliers work toward meeting the "4-3-2-1-0" Drinking Water Objectives. These communities have insufficient capital and providing a cost-effective system that provides safe drinking water at all times, is a challenge. Although many high-cost options were provided, the recurring theme of inadequate resources, funding and government's lack of support to small systems dragged solutions on and maintained Boil Water Notices to the detriment of all parties. A safe and cost-effective treatment option for these communities is the provision of multi-barrier safeguards including filtration with cartridge-filters, UV disinfection to provide an additional barrier and chlorination with a residual. The phased upgrade approach is generally feasible and economical for small systems. The challenges of providing a water treatment system design that meets the current regulations and is affordable for small communities will be elucidated in this paper.
