Over 300 million people in rural sub-Saharan Africa lack basic water service due to high infrastructure costs. Self-supply can increase basic water supply by stimulating families to co-invest in Household Water Systems (HWS) using Smart, Market-based, Affordable and Repairable technologies (SMARTechs). Examples include manual drilled wells ($200), locally produced hand pumps, solar pumps, rainwater harvesting and household filters. These technologies provide basic water service in areas with >200mm annual rainfall at $25/person average investment – often 50% less than conventional communal supply models. During this session, we’ll share experiences demonstrating how this sustainable approach reduces rural water supply costs whilst improving pump functionality and impacting multiple SDGs including poverty, food security, gender equality and climate action.

In flood-prone regions, standard sanitation systems fail, forcing communities into a “build-neglect-repair” (BNR) cycle that perpetuates health risks. This session spotlights successful Flood Resilient Toilet (FRT) technology piloted in India and Bangladesh through WASTE’s FINISH Mondial programme. By elevating toilet pits, sealing chambers with porous growth media, and enabling natural treatment when waterlogged, these units remained functional during major floods without contamination. The enabling environment proved equally critical – microfinance partners in India provided post-flood loans ensuring households could repair WASH hardware, preventing service gaps. You’ll hear firsthand from local partners, financiers and innovators who developed this technology as they share lessons and explore policy levers and collaborative pathways. Expect to leave with an understanding that climate-resilient WASH requires integrated hardware designs and responsive institutional support.

Malnutrition rates in developing countries remain high. While the majority of the population is small-scale farmers, most rely on rain-fed mono-cropping, hence their investment capacity is limited. The abundance of agro-workforce offers great potential to increase food security. However, financial capacity of small-scale farmers is limited, and fields are often too remote to leave equipment overnight. During this session, we’ll demonstrate that portable solar pumps help farmers double food production, increase crop diversity, and provide domestic water access right at the doorstep.
