Rain garden

Rain Gardens

  • Collect storm water directly from your roof
  • Store and repurpose it for many uses


Non-point source pollution is the term used by the EPA to define pollution from rainwater run-off. This type of pollution is recognized as the leading case of degradation in our lakes streams bays and coastal waters today.

Rain gardens are a storm water management tool that uses biomass to absorb water during a rain to prevent it from "running off". Generally they are just a shallow bowl in the earth with loose sandy soils and deep rooting vegetation, but do not let the simplicity fool, they are a very effective means of preventing non-point source pollution.

During rains water from rooftops and driveways tends to end up running into the street and becoming a burden on the municipal sewer system. Municipal systems are designed to handle the amount of rain that falls on them, not every house and property that abuts the street. In rural areas too many rooftops and large driveways can produce significant water volumes which transport silt, fertilizers and pollutants into the streets. This water volume can lead to flooding of lower lying homes, overflowing of the municipal storm-sewer and contamination and flooding of small creeks and streams. In cities, especially older ones, run-off water can combine with a sanitary sewer which causes an overflow into waterways of combined storm and sanitary sewer water.

A rain garden can be very simple yet effective means of slowing down this water, removing some (or all) of the pollution load and taking the energy and heat from the roof or drive. Rain gardens can be simple swale or dish based planters with unassuming natural grasses to ornate gardens with hardscapes.

A rain garden can also be coupled with other water-saving devices such as rain barrels or cisterns.
