the concept--
if an average american roof collects 4, 50 gallon barrels of water, after a 3 inch rainfall, times 100 roofs in the neighborhood, 20,000 gallons of water is diverted from the sewer system, as each roof acts as a collector, and the barrels at each corner of the house, are storage bins, if, after the rain has subsided, and the streets are dry( or the flood-threat has passed), the barrels could then be pumped empty( via a sump-pump in each barrel), to be ready for the next large rain-fall, thus eliminating flooding in low-lying areas--
note--
for those that garden, the water is of use for irrigation, but, for all, there is the benefit of flood-water diversion, if this problem exists in the area...
here are the rough numbers i gathered in my head, while walking the other day( and the reason i believe, a rain-gauge should be 1 inch square, and graduated in milliliters, to make math easy for roof-top rain collection computations)--
the numbers--
a roof 50 ft x 100 = 5,000 square feet
5,000 sq feet x 144 sq inches = "roof sq inches" (720,000 sq inches)
720,000 "roof sq inches" x milliliters of rain in rain-gauge = "total milliliters collected" by roof
"total milliliters collected", is then converted to "gallons expected" in rain barrels
gallons per home x number of homes in flood-zone = "gallons of water prevented"( flood waters)...
(the longhand of these figures will be posted soon)--
the point--
i feel that stemming a flood, by delaying a large volume of the rain-fall, until after the rain stops( a pre-set number of hours), and then releasing the stored/prevented water, in a second, controlled "micro-flood", may prove effective...
"smart-barrel" construction--
the device to accomplish this, could be a simple automatic drain valve, for a person's rain barrels on the gutters of their home, consisting of, a simple 12 volt electric water valve( like those used in RV's), a battery to power it, a solar panel to charge the battery, a timer, and a sound-sensor( that hears the droplets of water hitting the top of the barrel...thus turning the timer on), this electronic timer, would then count the minutes/seconds that pass, after sensing the rain has stopped( no sound of rain-droplets hitting the top of the barrel), immediately following the pre-set time having passed( three time-settings, or off ), the drain-valve would then open, or a pump would turn on( 12 volt RV water pump), thus emptying the barrel...flood averted--

Flood and water damage is a serious problem people should not take lightly. It is dangerous to you and your family, or maybe your workers in your office. Mold growth and damage to your home or office will become worse if a full staff of professionals do not come in and repair and restore your home to a useable condition. Water will creep its way into small crawl spaces, drywall, ceiling tiles, cabinets, ect.

in a city with great numbers of homes built close together, rain barrels can stem huge amounts of water from the sewer system, due to the close proximity of the roof-tops that are acting as rain collectors(if rain-barrels are used), in rural areas, with roof-tops very far apart, the concept works less well(although, water diverted from a big city's sewer system upstream from a rural area, that goes into a lake there, might prevent the banks of the river in that rural area from over-flowing)...it all adds up-- best wishes, john k
