Five Ways to Improve Stormwater Management at Home

Stormwater runoff from the roof and driveway often flows to the street and directed into the municipal storm sewer system. As the runoff travels, they pick up harmful substances like heavy metals, salt and oil which can end up in water bodies like lakes and streams, harming aquatic habitat and water quality.

Improving stormwater management on your property is important to improve drainage that can in turn reduce the risk of basement infiltration, flooding and erosion. Below are some tips to better manage stormwater at home.

Make your Own Rain Garden

A rain garden is designed to capture, filter and infiltrate rainwater. It can make an appealing detention area that allows runoff to soak into the ground. Compared with a traditional lawn, rain gardens allow a minimum of 30 percent water infiltration into the ground. Browse the web to get dependable ideas on building type of garden.

 

Grow some Trees

Increasing the amount of green space around your house can be done by planting native trees. Trees minimize stormwater in many ways. They capture and store canopy rainfall and release water into the atmosphere through the process called evapotranspiration. The leaf litters and roots of trees make soil conditions which promote rainwater infiltration into the soil. This helps in replenishing the groundwater supply and maintaining streamflow during the dry season. Also, trees help in slowing down and storing runoff temporarily, which is important to decrease flooding and erosion downstream.

Use Rain Barrels

These barrels serve as aboveground water storage vessels. They are designed to capture runoff from the roof with a gutter and downspout system. These tools are made with a drainage valve for storing water which can be used between rain events. Once opened, the valve allows water to empty out, decreasing runoff and increasing infiltration.

Keep the Stormwater Clean

Storm water can easily pick up sand, oil, bacteria and litter while flowing over the land and carry the pollutants to water bodies. Paved surfaces like parking lots, roads and rooftops can be sources of runoff which contributes huge amounts of polluted stormwater. Reducing the amount of pollutants can go a long way to make the stormwater clean while flowing into the water bodies.

Consider Permeable Pavement

Permeable pavement allows stormwater to infiltrate percolate through the surface into the soil below where natural water filtration and pollutant removal by a subsurface drain take place. It can be used in place of standard concrete or asphalt for surfacing driveways, walkways and parking areas.
