What is stormwater?

Stormwater is rainwater or melted snow that runs off streets, lawns, and other sites, which is typically absorbed into the ground and ultimately flows into streams and rivers. Impervious surfaces such as pavement and roofs, however, prevent stormwater to naturally soak into the ground. The water instead runs rapidly into storm drains, sewer systems, and drainage ditches, which can cause a wide range of problems, including downstream flooding, stream bank erosion, sewer overflows, infrastructure damage, contaminated streams, rivers and coastal water.

Stormwater Management Products

UltraTech International Inc. offers a comprehensive line of stormwater management products to effectively prevent various types of pollutants and contaminants, including hydrocarbons, dirt and sediment, from entering waterstorm systems, storm drains, catch basins and curb inlets.

Cost-Efficient Solutions

Advanced erosion control products from UltraTech International Inc. are cost-efficient solutions to prevent erosion and minimize sediment runoff found in stormwater. All UltraTech International Inc. dewatering bags, silt dike barrier systems, and gravel bags are designed to effectively capture trapped sediment and oil and to prevent erosion and infrastructure damage.
