water supply

[jesm]

Indeed Don, I feel every homeowner should have some amount of on-premise storage. Tinaco, cistern, something to carry on thru a short-term shortage. Very inexpensive insurance IMO. Most water utilities figure an average household uses around 75 gallons per day, exclusive of irrigation uses. An 1100 liter tinaco would be good for 3-4 days, or much longer if you went to any form of deep conservation, then you are at a week or more.
As mentioned GTO city is hghly dependent on ranfall fed reservoirs for much of our available water. One or two low rainfall years and we are back again to a mandatory, but mild (every other day) conservation program. With a tinaco you never even know it happens.
