This study evaluated the water-quality benefits of a new urban best management practice design called the multichambered treatment train (MCTT). The study consisted of collecting flow-weighted water-quality samples at influent and effluent locations for 15 consecutive storms. Device
efficiencies were based on load reductions of 68 constituents. Total rainfall amounts for the 15 storms ranged from 0.45 to 3.48 cm, yielding 1.7 to 8.9 m3 of water treated by the device. None of these storms surcharged the unit. High reduction efficiencies were found for all particulate-associated
constituents, such as total suspended solids (98%), total phosphorus (88%), and total recoverable zinc (91%). Dissolved fractions had substantial but somewhat lesser removal rates (dissolved phosphorus, 78%; dissolved zinc, 68%). Total dissolved solids, which originated from road salt storage,
yielded 4 times the total suspended solids load. No appreciable shift was seen between influent and effluent particle size distributions.
