These sediment flushing systems are designed to remove settled debris from storm water detention tanks, combined sewer overflow (CSO) retention tanks, sanitary sewer overflow (SSO) equalization tanks and reservoir floors, as well as sewer inverts, using a single flush. They can and have been used in CSO, SSO, agricultural and in industrial applications to clean any batch process tank, reservoir or basin.
These systems operate by releasing a torrent of water resulting in a flushing wave which progresses down the entire length of the flush way, pushing the settled debris ahead of it. The re-suspended debris is then carried by the flush water to the treatment plant for disposal.
These systems are designed to maintain maximum water storage levels upstream of the weir, thus allowing full usage of all the available upstream storage volume, while not adversely affecting the overflow weir capacity.
These systems are designed to remove debris from storm water overflow systems, combined sewer overflow (CSO) systems and sanitary sewer overflow (SSO) systems.
These systems are designed to maintain a constant and accurate flow (+/- 5%) from a minimum of 16 gpm (1L/s) to a maximum of 32 000 gpm (2000 L/s) and for upstream water levels varying from 0 to 40 feet (12 m).
These systems are designed to prevent flooding and backflows caused by high downstream water levels.
These systems are designed to reduce floating debris from entering the storm water overflow systems, combined sewer overflow (CSO) systems and sanitary sewer overflow (SSO) systems.
