Perhaps another pipeline
I suggest we build a massive flood-control pipeline to move water from Harris County to West Texas. Floodwater could be pumped out of reservoirs and detention ponds into the pipeline and transported to a reservoir somewhere in West Texas or the Panhandle. The water could then be processed and used for irrigation.
In addition to alleviating flooding, it also would reduce the depletion of aquifers because so much irrigation involves the use of ground water.
I realize that such a pipeline would be very expensive, but over the long haul, it would less costly than repeatedly repairing flood damage.
Water is a precious commodity, and we must learn to manage it instead of reacting to it. A flood control pipeline could be the answer.
