The fourth National Level Learning Alliance platform (NLLAP) took place on Thursday 4 March 2010 on the theme, “Sustainable Services at Scale”. The platform hosted the Triple-S project's research validation workshop which aimed to create awareness and share information about the Triple-S initiative, confirm the findings from baseline research, identify any gaps in the research and highlight opportunities and challenges in the water sector that affect sustainability of services delivery. This communiqué is intended to share the issues brought up during the meeting with the wider WASH community.
