Modular, Efficient Stormwater Storage System for Volume Control Applications
The Jensen Underground Stormwater Detention and Infiltration Reservoirs are precast modular stormwater storage systems that achieve the most economical means to meet small and large scale volume control requirements for both public and private projects. Our underground stormwater detention systems supports project-specific goals including storage volume, runoff flow rates, water quality, and erosion control. Underground stormwater detention systems maximize the land use of the development, especially where space is tight and land costs are significant.

How It Works
- Diverted stormwater runoff is captured and pumped into precast concrete detention and infiltration structure.
- Stormwater runoff is pretreated for removal of trash and debris through Jensen Deflective Separator.
- Coalescing separators and filters perform advanced treatment of stormwater runoff pollutants.
- Treated stormwater runoff is stored via rainwater harvesting package for irrigation use or slowly released via infiltration into the ground.
