Distribute locally-manufactured ceramic pot filters that cost under $10 and last 2-3 years. These filters remove 99.9% of bacteria and are already used successfully across Southeast Asia and Central America. Pair with a community education program on maintenance.
Factory-built modular housing units can be produced 30-50% faster and 10-20% cheaper than traditional construction. Units are built in controlled environments (no weather delays), transported to site, and assembled in days. Companies like Factory OS and Katerra have demonstrated this at scale.
