Unfolding ‘big’ problems of small water system performance: a qualitative study in British Columbia

Abstract In this study, small water systems (SWSs) serve a population of less than 5,000. This paper includes responses to a qualitative questionnaire from 66 SWSs (33% out of 200 SWSs) that identify the major problems within these systems across British Columbia (BC). Focusing on four interrelated components of SWSs (water quality issues, treatment and disinfection, water quality monitoring and water governance challenges), the identified major problems include: insufficient water monitoring programs; inadequate treatment prior to disinfection; insufficient funds to build water infrastructure; high turbidity; iron and manganese in source water; microbial contamination, especially in distribution networks; and high disinfection by-product formation. Based on the findings, the authors recommend implementing efficient water policies suitable for SWSs and strengthening funding support from governments. Developing long-term plans for effective management of water resources, while building strong communication among relevant stakeholders (ie municipal managers, operators and consumers), can also play a significant role in ensuring safe drinking water supplies. The findings can help BC policymakers understand the major problems of SWSs and their root causes.
