What about rainwater storage?


Both Shorewood and Whitefish Bay are experiencing the shortcomings of storm water systems designed many decades ago under standards not too far advanced from those of the Romans. 


A few years ago we experienced heavy rains that overwhelmed theses “undersized” drainage systems.  It seems that the engineering problem is one of preventing flooding as economically as possible under restricted surface absorption characteristics.


Last year we had drought conditions in this area.  If the time spread of water of over our area over the last number of year would have been more even, we may not have experienced sewer backups and perhaps not had drought conditions even in our built-up communities.


It seems that the more even quantity of rainwater over an impervious surface can only be achieved by engineering solutions involving more rapid drainage perhaps combined with large capacity storage. 


I’m not sure as to whether storage systems separate from sanitary water have been considered.  In economic situations where most of the land surface must be covered and most of the remaining uncovered land is imperious, it would seem that a lot of hydraulic engineering intelligence should be devoted to storage and use of drainage water in dry periods.  


There must be some techniques of this nature that have been explored in other parts of the world.  Financial bookkeeping policies alone, usually take us back toward the old Roman techniques.  Shouldn’t we consider some unique methods for water reservoirs?
