Knowledge, Satisfaction, Water Quality, Water Treatment
Conditions
Brief summary
The objective of this study is to evaluate the effects of a novel financial and capacity strengthening intervention (the 'Water Quality Assurance Fund' program) on water safety management in rural Ghana and Kenya. The investigators hypothesize the intervention will improve water system operator knowledge, chlorination practices, and water quality at the point of collection, as well as improve consumer satisfaction, awareness, and willingness-to-pay for water that is tested and treated.
Detailed description
Regular water quality monitoring by water suppliers is essential for maintaining adequate treatment processes and verifying safe water quality to protect public health. Yet, many small water suppliers are unable to conduct regular water quality tests due to financial, logistical, and capacity constraints. The goals of the Water Quality Assurance Fund program are to address these constraints by incentivizing established laboratories to extend their services to these smaller water systems and, in parallel, promote the use of water quality data for better water safety management. The objective of this study is to evaluate the effects of a novel financial and capacity strengthening intervention (the 'Water Quality Assurance Fund' program) on water safety management in rural Ghana and Kenya. As part of the intervention, written legal agreements between water systems, centralized laboratories, and the organization facilitating the Assurance Fund will provide water systems with regular water quality testing and provide laboratories a guarantee of payments if water systems fail to pay for testing services on time. The Assurance Fund program will also deliver capacity strengthening, technical guidance, and community sensitization activities. The investigators hypothesize the intervention will improve water system operator knowledge, chlorination practices, and water quality at the point of collection, as well as improve consumer satisfaction, awareness, and willingness-to-pay for water that is tested and treated. A secondary aim is to assess implementation challenges and enabling factors associated with the expansion of water testing services by existing professional water quality laboratories to rural water suppliers.
Interventions
* At the water system level: Written legal agreements between water systems, centralized laboratories, and the organization facilitating the Assurance Fund will provide water systems with regular water quality testing and provide laboratories a guarantee of payments if water systems fail to pay for testing services on time (for up to three concurrent unpaid invoices). Regular debrief meetings will be held with water operators and local government authorities to discuss test results and water treatment options, and to encourage water systems to share water quality information with their consumers. Technical guidance to improve water treatment will be provided, if requested by water system operators or local government authorities. * At the community level: Community engagement, primarily at the onset, to inform the community about the water quality testing program and answer questions.

Eligibility
Inclusion criteria
Eligibility to receive the intervention was determined by water system criteria: Inclusion Criteria: * The district or county government was interested in participating in the Assurance Fund program and water systems within the district/county were accessible to a partner central laboratory that was able to provide water sample collection and testing services for a fee. * Water systems were functional. * Water systems were piped water systems (Kenya, Ghana) or mechanized boreholes with a single tapstand (Ghana). * Water systems could afford regular water quality testing from the selected laboratory.
Exclusion criteria
* Water systems did not meet above inclusion criteria. To be eligible to participate in household surveys, participants need to be at least 18 years of age and a customer of a eligible water system.
