A household water treatment implementation framework: lessons learnt from the diversity of implementation worldwide

Household water treatment (HWT), the use of simple accessible technologies for treating water within the home, is gaining momentum globally. As estimates of worldwide users top 1.1 billion and efforts focus on scaling up existing HWT programs, there is a need to document lessons learned from HWT implementation to date and disseminate them among new and existing implementers. CAWST’s review of current implementation practices coupled with years of experience working with implementers worldwide has demonstrated that while no one standard model exists, successful program implementation shares common factors. These factors have been developed into an implementation guidance framework, focused on five key areas; creating demand, ensuring supply, monitoring and improving implementation, building human capacity, and sustained financing

Power of knowledge in executing household water treatment programs globally

This paper presents a case study of five organizations from five countries: Haiti, El Salvador, India, the Philippines and Pakistan, demonstrating that knowledge transfer can be a catalyst for locally-driven water programs for the poor. Each organization received training and technical consulting from the Centre for Affordable Water and Sanitation Technology on Project Implementation for the Biosand Filter. Each then established an independent project resulting in cleaner water for 156,000 people in six years, and widespread biosand filter acceptance among users. Lessons learned are that knowledge transfer can result in effective, sustainable and scaleable technology implementation; transfer takes place one person at a time, making education at all levels crucial; pilots/demonstrations are essential motivators to technology adoption; involvement of mainstream government can result in faster implementation and widespread acceptance; and technology training is not enough. Organizations need to learn how to plan, implement and monitor programs
