Under a City of Ventura Storm Drain Maintenance contract, Downstream Services Stormwater Department discovered a vault with 160 Contech cartridges that had more than 17 inches of sediment causing the cartridges to clog, hold water and not function as designed.
Due to the amount of sediment, four transportable treatment bins were setup for solid waste removal and dewatering for transportation. Once all cartridges were removed, the vaults were cleaned and cartridges reinstalled in record time.
