Small piped water supply systems are often unable to provide reliable, microbiologically safe, and sustainable service over time, and this has direct impacts on public health. Circuit Rider (CR) post-construction support (PCS) addresses this through the provision of technical, financial, and operational assistance to these systems. CRPCS operates in low and high-income countries; yet, no rigorous studies of CRPCS exist. We measured the impact of CRPCS on ‘water quality’ and ‘sustainability’ indicators (technical and administrative capacity, and water supply protection) in El Salvador. In this field-based study, a case-control design was utilized in 60 randomly selected case (28 CR) and comparable control (32 noCR) communities. Microbiological water quality tests and pre-tested structured key-informant interviews were conducted. The operational costs of CRPCS were also assessed. Data were compared using parametric and non-parametric statistical methods. We found communities with CRPCS had significantly lower microbiological water contamination, better disinfection rates, higher water fee payment rates, greater transparency (measured by auditable banking records), greater rates of household metering, and higher spending for repairs and water treatment than comparable control communities. CRPCS is also a low-cost (<$1 per household/year in El Salvador) drinking water intervention.

Abstract Inter-household patterns in drinking water access, consumption, perception, and quality among residents can vary in Rio das Pedras (RdP), a large favela in Rio de Janeiro, Brazil. While unreliable water quality can influence residents to diversify their drinking water supply, household drinking water management practices are not generally known for this community. Household surveys, and indoor tap, piped water before entering the home, filtered, or bottled dispenser water samples were collected. Respondents reported storing water (91%) and near-daily access to piped water (78%). A majority of households reported cleaning water storage tanks at least once every 6 months. Also, residents rely on bottled water and a considerable proportion supplemented their water supply with at-home filtered water. The quality and safety of these sources are not necessarily superior to indoor tap water, especially under conditions of appropriate water storage tank cleaning. Higher prevalence of total coliform detections was found in indoor tap, filtered, and bottled water. Household characteristics such as home ownership, residence type, and residence time exhibited a positive association with improved tank cleaning. Community health practitioners could evaluate practices in water storage, at-home filtration maintenance, and bottled water dispenser systems using household characteristics to promote protective actions.

Abstract The work is an attempt to assess piped water quality in four counties located in east central Poland. Piped water was analysed for three successive years in each county. Water samples were tested for the following physical and chemical parameters: turbidity, colour, conductivity, taste, odour, pH, nitrates (III), nitrates (V), iron and manganese. They were compared with the current standard values. Preliminary data analysis included an analysis of maximum and minimum values of physical and chemical parameters, and it revealed that turbidity, colour, iron and manganese contents exceeded the permissible standards in all the counties. Percentages of parameters exceedances and mean values of the exceedances were used to rank the counties in terms of water quality. The ranking was obtained by means of multidimensional comparative analysis. It was demonstrated that best quality water was supplied by Węgrów County water supply system which was followed by Mińsk Mazowiecki County. The third rank was assigned to Łosice County and the poorest quality water was found to be supplied by Siedlce County water supply system.
