The natural ability of the ground to control water is compromised by the construction of buildings, roads and parking lots on previously undeveloped areas. The problems associated with stormwater quantity and quality are becoming more apparent with increasing urbanization and changing weather patterns. Stormwater runoff from impervious surfaces often carries a high pollutant load that has a detrimental effect on the bodies of water into which it discharges. Hydro International provides solutions to challenging stormwater problems.

Municipal wastewater treatment plants (WWTPs) require significant investments in high performance treatment processes such as membrane bioreactors and digesters. To protect this equipment, effective grit separation and dewatering is required to prevent abrasion, grit deposition, and equipment failure. As plant process equipment becomes filled with grit, operational efficiency decreases until the processes have to be shut down to remove the grit. Hydro International’s grit removal systems are designed to provide the highest level of grit removal efficiency with minimal maintenance, energy, and operational requirements.

Wet weather events are one of the leading causes of water quality degradation nationwide.  Wet weather runoff can hydraulically overload sewers and treatment facilities, causing overflow events known as combined sewer overflows (CSOs) or sanitary sewer overflows (SSOs).  These overflows discharge a mixture of untreated stormwater and wastewater carrying human waste, trash, debris and toxic waste directly into a receiving water body. Today’s municipalities require innovative technologies to economically and effectively address the growing problems associated with Combined Sewer Overflows (CSOs) and Sanitary Sewer Overflows (SSOs) caused by wet weather. Hydro International is the leading expert in wet weather management, providing efficient, cost effective solutions to prevent, treat or abate wet weather overflows.
