Bioretention & LID

EQRs’ experience spans over 25 years installing and maintaining many different types of LID/ESD projects and has been one of the leaders in the industry developing specifications and details for the design community. These systems include rain gardens, bioretention facilities, infiltration and filtration swales, gravel wetlands, high flow media systems, permeable pavements, cisterns and proprietary filter systems. Our trained crews understand these facilities are designed to retain water and filter pollutants and follow quality control procedures to make sure we meet regulatory and design parameters.


Additional functions are pollutant filtering, heavy metal removal, thermal pollution reduction, reduction of high energy flow levels, evapotranspiration while providing habitat for birds and beneficial insects in an attractive native landscape.  Many bioretention areas and other LID systems require underdrains, (piping), cleanouts and observation wells and stone storage layers.  Most include highly engineered soils, mulch, and native plants.
