Reference excerpt

The Rural Water Supply Network (RWSN) is a global, multi-stakeholder network focused on achieving universal access to safe, affordable drinking water for all rural people worldwide. Established in 1992 as the Handpump Technology Network (HTN), the organization originally concentrated on the development and maintenance of handpump technologies. Over time, it expanded its scope to address broader rural water supply issues, and in 2004, it was rebranded as RWSN. The network has no legal structure and instead is a loose collaboration. RWSN operates on the principles of collaboration, knowledge sharing, and capacity building among its members. The network is organized into various thematic groups, such as sustainable groundwater development, self-supply, and the professionalization of community water management. RWSN runs webinars, facilitates online discussion communities and publishes peer-reviewed guidelines and case studies. Funding for RWSN comes from a combination of membership fees, grants from international donors, and contributions from partner organizations. The RWSN secretariat had income for the period 2018-2020 from 15 sources of partner contributions and project funding. The largest single contribution (30%) was from the Swiss Agency for Development and Cooperation (SDC). The secretariat complements its core funds with project based work.

Rationale and regional focus The RWSN networking activities focus on rural people most in need of safe access to drinking water, which means its geographic focus by default is developing countries in sub-Saharan Africa, Latin America and Asia. However, in principle anyone living in a rural area anywhere in the world could benefit from the network's activities. The underlying problem that a network such as RWSN is trying to solve is that millions of people in rural areas of developing countries have no access to safe drinking water. For example, an estimate in 2016 put the figure at 300 million people without safe drinking water in rural Africa. The Joint Monitoring Programme for Water Supply and Sanitation of WHO and UNICEF said in 2022 that 411 million people in Africa (3 out of 5 people) still lacked basic drinking water services in 2020. The situation is worse for rural areas in Africa where only 22% had access to basic drinking water services in 2020 compared to urban areas with 59%. Target 6.1 of Sustainable Development Goal 6 is: "By 2030, achieve universal and equitable access to safe and affordable drinking water for all". Through its work, RWSN aims to address the challenges faced by rural communities, such as inadequate infrastructure and limited financial resources. Since around 2021, RWSN is also explicitly working on aspects that are related to the impacts of climate change, such as climate resilient water services in rural areas.

Activities

The aim of RWSN is "to improve the quality of rural water services and their management".

Knowledge sharing and networking Key activities of RWSN include the development of technical guidelines and standards, the dissemination of research findings, and the promotion of innovative technologies and approaches. RWSN participates in the creation of peer-reviewed guidelines and case studies which are hosted in the RWSN virtual library on their website.

RWSN regularly runs activities around knowledge sharing and networking, such as online discussion groups and webinars in English, French and Spanish on topics relating to rural water supply and WASH (water supply, sanitation and hygiene). For example, the World Bank and RWSN ran their first joint webinar series in 2012. WHO and RWSN had a joint "Launch webinar for WHO guidelines and tools to enhance small water supplies" in February 2024. RWSN provides a platform for raising awareness around chronic failures in water supply systems. The platform also supports activities around research and drilling professionalisation and new service delivery models. Every year at the World Water Week in Stockholm that is organised by Stockholm International Water Institute, RWSN is convener and co-convener of several sessions to advance the debates around rural water supply.

International standard specifications for handpumps When organisations specify handpumps in contracts, there are often questions around specifying the pipes and rods. To help with this problem, RWSN has published international standard specifications for some handpumps, for example the India Mark II and III handpumps. These specifications have to be regularly updated and maintained, and RWSN facilitates this process. This can be done for example by leaning on international standards bodies, in particular ASTM and ISO.

Organising global conferences Every five years since 1992, RWSN has organised a global conference dedicated to rural water supply, called the RWSN Forum. So far, there have been seven RWSN Forums. All of them, except for one in India, took place in Sub-Saharan Africa:

The International Handpump Workshop in Kenya in 1992. 2nd HTN Workshop in Malawi in 1997. 3rd International HTN Forum in India in 2000. 4th Forum in South Africa in 2003 (called 4th International HTN Forum). 5th RWSN Forum in Ghana in 2006. 6th RWSN Forum in Uganda in 2011. The most recent conference was the 7th RWSN Forum in Abidjan, co-hosted by the Government of Cote d'Ivoire, in 2016. It was opened by the then Prime Minister Kablan Duncan. One of the main sponsors of the event was the African Development Bank through its Rural Water Supply and Sanitation Initiative (RWSSI). The 8th RWSN Forum in 2021 was postponed due to the COVID-19 pandemic. There have been no announcements of upcoming RWSN Forums since then.

Structure

Secretariat and members The secretariat has been hosted from the start and until now by Skat Foundation in St. Gallen, Switzerland. It coordinates and runs the network activities, in partnership with theme leaders and under the supervision and guidance of the executive steering committee. Membership for individuals and organisations is free and not time-limited. RWSN has over 16,000 members in 168 countries (as of 2023) from government agencies, non-governmental organizations (NGOs), research institutions, and private companies.

Worked examples

Example 1 — a first encounter with Rural Water Supply Network

Start with the simplest possible case. Write down what Rural Water Supply Network claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Rural Water Supply Network before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Rural Water Supply Network ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Rural Water Supply Network

In research: Rural Water Supply Network appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Rural Water Supply Network in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Rural Water Supply Network is common in secondary-school and first-year university syllabi. It links to neighbouring topics Water organizations, so understanding it makes those chapters shorter.
In everyday life: Look for Rural Water Supply Network outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
