Impact of Household Water Treatment Education on Safe Drinking-Water Practices among Rural Households in Nigeria

Abstract

Access to safe drinking water is an essential component of public health, yet many rural households in Nigeria continue to depend on water sources that may be vulnerable to contamination. Consumption of contaminated drinking water can contribute to diarrhoeal diseases and other waterborne infections, particularly where sanitation and hygiene conditions are inadequate. Household water treatment is an important public health intervention that can reduce microbial contamination of drinking water at the point of use. Household water treatment education provides individuals with information and practical skills concerning appropriate water treatment methods, including boiling, chlorination, filtration, solar disinfection where appropriate, safe water collection, hygienic storage, and protection of treated water from recontamination. Safe drinking-water practices include treating water appropriately, using clean and covered containers, avoiding contamination during collection and storage, using clean utensils to retrieve stored water, and maintaining hygienic conditions around household water sources and storage facilities. In Nigeria, inadequate knowledge of household water treatment, limited access to treatment materials, dependence on unimproved water sources, poverty, and poor sanitation facilities may affect the adoption and consistent practice of safe drinking-water behaviours among rural households. Effective household water treatment education may improve knowledge, practical skills, and adoption of appropriate water safety practices. Against this background, this study investigates the impact of household water treatment education on safe drinking-water practices among rural households in Nigeria. The study is anchored on the Health Belief Model, Social Cognitive Theory, and Knowledge-Attitude-Practice framework. The Health Belief Model explains preventive health behaviour through perceived susceptibility, perceived severity, perceived benefits, perceived barriers, and cues to action, providing a basis for understanding household decisions regarding drinking-water safety. Social Cognitive Theory emphasizes the interaction between knowledge, self-efficacy, behavioural capabilities, social influences, and environmental conditions in shaping household water practices. The Knowledge-Attitude-Practice framework provides a basis for examining how improved knowledge and attitudes resulting from household water treatment education may influence safe drinking-water practices. Collectively, these theoretical perspectives provide a suitable framework for explaining how household water treatment education may influence safe drinking-water practices among rural households in Nigeria. The study will adopt a quantitative quasi-experimental research design. Primary data will be collected from selected rural households in Nigeria using a structured interviewer-administered questionnaire and a household water and sanitation observation checklist. Where feasible, water samples may also be collected and tested using appropriate microbiological procedures to provide objective evidence of drinking-water quality. A multistage sampling technique will be employed to select states, local government areas, rural communities, households, and eligible adult respondents. Where feasible, selected communities or households will be assigned to intervention and comparison groups. Households in the intervention group will receive structured household water treatment education covering sources of drinking water, risks associated with contaminated water, appropriate household water treatment methods, safe water collection, hygienic storage, prevention of recontamination, cleaning of water containers, and appropriate hygiene practices. Safe drinking-water practices will be assessed using indicators such as household water treatment, frequency and consistency of treatment, appropriate treatment method, safe water storage, use of covered containers, cleaning of storage containers, use of clean utensils for water retrieval, and protection of treated water from contamination. Descriptive statistics will be used to summarize household characteristics, exposure to water treatment education, and safe drinking-water practices. Inferential statistical techniques, including chi-square tests, paired-sample tests, independent-sample tests, and multiple regression analysis, will be used to determine the impact of household water treatment education on safe drinking-water practices. Appropriate diagnostic tests will also be conducted to assess the reliability of the research instrument, model assumptions, goodness of fit, and robustness of the findings. The study is expected to find that household water treatment education has a significant positive impact on safe drinking-water practices among rural households in Nigeria. Households exposed to structured water treatment education are expected to demonstrate improved knowledge of drinking-water safety and greater adoption of appropriate household water treatment and storage practices. Education may encourage regular treatment of drinking water, appropriate selection and application of treatment methods, hygienic water collection, safe storage, regular cleaning of water containers, and prevention of recontamination. Where water-quality testing is conducted, improved household practices may also be associated with better microbiological quality of stored drinking water. However, education alone may not guarantee sustained safe water practices because rural households may face barriers such as limited access to safe water sources, cost and availability of treatment materials, inadequate sanitation facilities, poverty, distance from water sources, and difficulty maintaining treatment practices consistently. Consequently, household water treatment education is expected to be most effective when supported by reliable access to safe water, affordable treatment materials, improved sanitation infrastructure, and community-based water, sanitation, and hygiene programmes. The study is expected to contribute to the literature on water, sanitation and hygiene, household water treatment, environmental health, health education, infectious disease prevention, and rural public health in Nigeria by providing empirical evidence on the impact of household water treatment education on safe drinking-water practices among rural households. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, Federal Ministry of Water Resources and Sanitation, National Primary Health Care Development Agency (NPHCDA), state ministries of health, rural water and sanitation agencies, local government authorities, environmental health officers, community health workers, development partners, humanitarian organizations, and policymakers regarding strategies for improving household drinking-water safety. The study will also provide evidence-based recommendations for strengthening household water treatment education, expanding access to affordable water treatment technologies, improving rural water infrastructure, promoting hygienic water storage, strengthening community-based WASH programmes, and reducing exposure to contaminated drinking water among rural households across Nigeria.
