WSUP has long-term partnerships with some of the most renowned trusts and foundation which has enabled us to rigorously test and scale-up innovative models that improve services for the urban poor.

Our trust and foundation partners

  • Bill and Melinda Gates Foundation and WSUP’s multi-country partnership began in 2007 and ended in 2018, helping provide at-scale improved water and sanitation services in Bangladesh, Ghana, Kenya, Madagascar, Mozambique and Zambia.

    Comic Relief has partnered with WSUP to help achieve its goal of a more secure, well-planned and healthy Lusaka, where empowered communities in urban settlements have improved livelihoods and increased fulfilment of their basic rights to equitable and quality services.

    Dubai Cares began supporting WSUP in 2017, working in Antananarivo and Mahajanga in Madagascar on a project aimed at improving access to safe water, sanitation and hygiene (WASH) in schools. In 2019, Dubai Cares extended support to WSUP through support of a project in Bangladesh which will improve WASH facilities in Bangladeshi schools in the target areas of Rangpur, Chattogram and Gazipur.

    Halcrow Foundation began supporting WSUP in 2017, working in the capital city of Madagascar, Antananarivo, on a project to increase access to safe water and basic sanitation for people living in low-income areas, whilst also improving hygiene behaviour.

    In 2019 the James Percy Foundation awarded WSUP a three-year grant to support the government-mandated water utility and a local water trust to improve the water supply in Chazanga, a peri-urban area within the city of Lusaka in Zambia.

    The Mulago Foundation has played a vital role in supporting WSUP’s strategic aims since 2015. The partnership has enabled WSUP to develop more efficient and financially viable services for low-income urban customers through strengthening utilities as well as public and private sector providers

    The Skoll Foundation awarded WSUP a prestigious Skoll Award for Social Entrepreneurship in 2013. In 2017, following a rigorous due diligence process, WSUP received a new investment from the Skoll Foundation to expand our SWEEP programme over four years.

    Stone Family Foundation (SFF) has supported WSUP since 2011, and in 2016 entered a four-year strategic partnership to support WSUP’s 2016-2020 Business Plan.

    Wasser für Wasser and WSUP have been partners since 2014, initially supporting projects focused on improving water supply in low-income areas across Lusaka. Our partnership with WfW has now expanded to Livingstone in Zambia where WfW are an enabling partner for WSUP and Southern Water & Sewerage Company in Livingstone, and to Maputo, Mozambique where we are working sanitation and hygiene interventions in low-income communities.


  • Improved water and sanitation services, along with improved hygiene practices, have a close connection to many other development challenges, such as health, gender equity, employment, inequality and children’s well-being.

    We work closely with trusts and foundations to identify how best to align their aims and objectives with our mission and goals, ensuring they are involved throughout.

    At the heart of many of these partnerships is a commitment to sharing and disseminating knowledge gained during the projects for replication and scale-up by the sector at a national and international level.

    In addition, our trust and foundation partners are invited to WSUP’s regular series of events, which aim to share learning and stimulate discussion in the sector.

It’s really hard to get water and sanitation to the people – all the people – who need it the most: we like the systematic way that WSUP brings together all of the key actors in a complicated landscape to drive lasting solutions that focus on the poor.
