Diverse Stormwater Solutions

A Complete Range…

We engineer and manufacture a complete range stormwater products, each designed to satisfy a specific application or achieve a regulatory requirement.

of Flexible Systems and Assistance.

Our pretreatment, detention, bio-retention, infiltration, rainwater harvesting and water quality systems are flexible. They can be deployed as stand-alone solutions or assembled as parts of a management solution into treatment trains for achieving high effluent water quality.

Jensen Stormwater Systems’ experienced team provides the following assistance and support materials to meet even the most stringent project requirements:

  • project designs
  • hydrology, hydraulics
  • plans, drawings, and specifications
  • installation guides, operations and maintenance manuals
