Project idea question: Could funding be raised from utility companies to implement water conservation measures using simple weighted, reused bottles for displacement in toilet tanks? Next step questions:
1) What is the amount of electricity saved per liter of water pumped?
1a) Are there meaningfu differences implied in multi-unit residential structres with multiple stories?
2) Are water utilities facing similar incentive programs to those recently faced by electricity providers, to reduce total energy use? If not, why?
