Stormwater Management and Best Management Practices

Every project must meet local, state and federal laws, regulations and rules governing the impact of property development or redevelopment on stormwater run-off. Engineers and contractors are challenged to meet regulatory permit requirements while seeking to maximize the utility and economics of the site and its improvements.

Low Impact Development (LID)

Most building jurisdictions have low impact development regulations for stormwater management. Compliance is required to get permits. Stormwater Manuals or guides often provide the local rules about stormwater run-off containment, water quantity flow control into storm drains, sewers or wetlands, stormwater detention, infiltration into underlying soils and longer term retention of stormwater.

  • Low Impact Development solutions often include underground systems for temporary stormwater detention, retention or storage that preserve the surface utility of higher value land instead of building large detention ponds.
  • RainSpace™ Stormwater Management Chambers are the most cost-effective means of meeting Low Impact Development stormwater management rules under parking lots, driveways and roads or under athletic fields, playgrounds, schoolyards, public plazas and open spaces.

NPDES – National Pollutant Discharge Elimination System

The NPDES permit requirements address stormwater runoff flows over land or impervious surfaces to reduce pollutants that harm rivers, streams, lakes, and coastal waters. Stormwater controls known as Best Management Practices (BMPs) reduce harmful pollutants by controlling them at the property. Best Management Practices often involve water treatment in stormwater detention or retention systems. BMPs may also use engineered bioswales to reduce pollutants.

  • The capacity of these bioswales engineered wetlands can be significantly increased with RainSpace Chambers under the soils and the surface footprint area reduced, leaving more useful land available on the site for alternate uses.
  • RainSpace Stormwater Management Chambers are the most cost effective means of meeting NPDES Best Management Practices when greater water storage capacity is desired under bioswales or engineered wetlands.

Collaborative Stormwater Management Planning 

  • Each RainSpace Stormwater Management system design and installation is the result of a collaboration between the project engineers and contractors and our design staff at Rain Tech, Inc. We work together to provide the best and most economical system design.

Stormwater Management Installation

  • RainSpace Stormwater Detention and Retention Chambers are installed quickly and easily.  The installing contractor lines the excavation with geotextile filter fabric (and an impermeable liner, if required for long term water storage) and the patented structural core tube bundles are quickly placed inside. Storm drain hook ups are made, the top is covered with the geotextile and the sides and top are back filled.
  • All the materials are lightweight and are easily handled at the site and quickly installed without using cranes or large equipment. A typical commercial or institutional installation takes a small crew one or two days to complete. We send a senior technician to each installation site to advise the installing contractor’s crew during the installation.
