Need to solve some of these:
- Storage. Single most expensive component of rainwater harvesting systems. Sintex tanks ain’t cutting it.
- Demand reduction
- Wastewater : its water + muck. The good news – Filtering this is a solved problem! So how do we create micro-water-cycles with only evaporation losses so we pump out as little “waste” water as we can. Basically, reduce the delta needed everyday as a household, community and fix #2 differently!
