Our work in rural water supply service delivery addresses institutional and regulatory aspects, finance and economics, political economy, technology, climate change, and water science.
Rural water supply in Vanuatu: assessment of coverage and service levels
This project sought to characterise the coverage and service levels delivered by rural water supply systems in Vanuatu. The assessment was based on data from the country’s rural water supply inventory, which comprises information on almost 5,000 water sources across 46 islands. Performance measures assessed included functionality, service continuity, gender equity, and sanitary conditions.

Beyond the Finish Line: Inclusive and Sustainable Rural Water Supply Services in Nepal
Client: SNV Netherlands Development Organisation
Rural areas in Nepal have high coverage of basic water supplies, but it is not clear whether everyone receives acceptable quality drinking water, and climate change threatens to disrupt water system sustainability. This research examines two areas: 1) Drivers of water contamination in rural area of Nepal and how these can be addressed, and 2) Service provider strategies for maintaining water service levels against climate impacts. Addressing these areas is critical for meeting safely managed water criteria and sustaining service levels.
Responding to climate change to sustain community-managed water services in Vanuatu
Clear conceptualisation of the different ways that community-managed water services are affected by and sustained against climate change is needed to inform appropriate adaptation interventions.
This research project examined the impacts of climate change on two communities in rural Vanuatu using risk-hazard, vulnerability, and social-ecological system resilience perspectives, and developed a conceptual framework to facilitate interdisciplinary research on climate change impacts on community-managed water services.
Evaluation of WaterCredit Project, India
Microfinance is a key pathway to support access to WASH services.
This project is examining the impact of a water and sanitation microfinance initiative in urban India. The assessment included a large household survey, focus group discussions, key informant interviews.
Groundwater and poverty in sub-Saharan Africa
Client: UPGro programme
A commissioned systematic review of the relationship between groundwater and poverty in sub-Saharan Africa. The work featured as Chapter 5 of the report ‘Groundwater and poverty in sub-Saharan Africa’.
Enterprise in WASH
Client: Australian Development Research Scheme Award (ADRAS) Grant
This research investigated the role of small-scale enterprises in sustainable WASH service delivery, with a focus on equitable outcomes for the poor. Conducted in partnership with civil society organisations and local research institutions in Indonesia, Timor-Leste, Vanuatu, Cambodia and Vietnam.
Research outputs focused specifically on rural water supply include:

Blue Pump performance evaluation
The BluePump is an emerging rural water supply technology, which utilises lever-action reciprocating handpump technology as an alternative to mainstream hand pump technology in rural sub-Saharan Africa.
Claims about the BluePump's durability and minimal maintenance requirements have provoked significant interest in the rural water sector. However, there are questions about the BluePump's initial cost, maintenance cost, and operational performance
In partnership with Oxfam, in the context of Kenya and the Gambia, ISF-UTS assessed the Blue Pump’s operational performance and other factors affecting the suitability and sustainability of the Blue Pump.

Rural water entrepreneurs: prevalence, predictors and prospects
This project investigates the role and impact of market-based approaches to rural water service delivery in Asia and Africa.
Based on fieldwork in Cambodia, Vanuatu and Sierra Leone, the research evaluates the prevalence, success factors, motivations and sustainability implications of rural water entrepreneurs.
This research applies critical mass theory to community waterpoint financial contributions in rural sub-Saharan Africa for the first time, to explain the initiation and spread of community behaviours. It also suggests that there is a tension between financial sustainability and universal access to water and sanitation, which requires further examination to ensure that rural water services are both sustainable and inclusive.

Sustainable service delivery in Timor-Leste
Client: Australian aid program Rural Water Supply and Sanitation Program (BESIK)
The Timor-Leste rural water supply sector faces a range of challenges, including imbalances between capital investment and recurrent costs, limitations in technical oversight and cases of poor quality construction.
The current institutional framework places communities as responsible for the operation and maintenance of small rural water systems. However, a balance needs to be struck between community and government responsibility.
Improving the sustainability of rural water service provision in Timor-Leste requires reorientation of the sector from an infrastructure focus to a service delivery approach.
This research provided recommendations on ways to shift the institutional arrangements for Timor Leste’s rural water supply sector from the current infrastructure focus, to a service delivery approach able to provide on-going sustainable services to rural populations.
