Have you ever Googled “Arizona Drywell”? You may find a definition of a simple rock filled pit or even better, a MaxWell Drywell. Well, the historic Arizona drywell did start as a shallow, rock filled pit.
It was in 1972 that the Arizona drywell began to revolutionize. As a result of increasing construction developments and residential growth, stormwater runoff had no place to go. The City of Phoenix was forced to address their stormwater flooding problems by developing a new drainage ordinance requiring on-site stormwater retention. Soon after that drywells began to flourish throughout Phoenix in grassy retention areas as well as other areas that suffered from flooding.
Since the historic Arizona drywells had no type of filtering device to filter out silt, sediment and debris, they quickly began to clog and became useless. Year after year, the MaxWell team at Torrent Resources continued to research, evaluate and develop a more effective drywell system, the MaxWell Type IV Drywell and the MaxWell Plus Drywell.
With over 75,000 MaxWell Drywells throughout Arizona and California, the team at Torrent Resources continues to grow this number of drywell installs each day. Our MaxWell Drywells provide the pretreatment necessary to infiltrate clean stormwater into the subgrade and replenish groundwater supplies. The MaxWell Drywell has now become the standard for Arizona drywells as well as the standard for California.
