The Best Ways for Enhancing your Stormwater Management Strategies

A bio-retention cell or a rain garden is a porous backfill-containing depressed area that’s beneath a vegetative surface. Frequently, such areas feature an under-drain for encouraging filtration and infiltration, especially in clayey soils. These cells provide pollutant removal, runoff detention, and groundwater recharge. They are stormwater solutions that are effective in parking areas or urban areas, in which there is limited green space.

Curb and gutter elimination:

Curbs and gutters convey flows to stormwater drains quite fast without allowing inlet filters to infiltrate or remove pollutants. Eliminating them can decrease runoff volumes and raise sheet flow volumes. Maintaining sheet flow by eradicating curbs and gutters that convey runoff into vegetated bio-retention swales and basins helps in preventing stormwater soil erosion. It also helps in preserving hydraulic conditions (pre-development). A level spreader (a channel designed for changing concentrated runoff into sheet flow before uniformly spreading it across a slope) could also be included. This is also to further prevent soil erosion.

Green parking designs:

When applied jointly, these decrease the contribution to total impervious covers from parking lots. Techniques for designing green parking lots include setting the maximum number of spaces a parking lot shall contain, minimizing the dimensions of each parking lot space, using bio-retention areas for the treatment of stormwater, using alternative types of pavers in parking areas that are overcrowded or very busy, and many other incentives that are valuable in promoting structured parking. These techniques can be truly effective for stormwater management.

Infiltration trenches:

These trenches are rock-filled and they do not feature any channels. Whenever there is a storm, they collect runoff, and through infiltration, release it into the soil. They can be used together with other devices that are meant for stormwater infiltration by means of using an inlet filter. This combination will certainly offer peak flow attenuation and significant water quality control. Runoff which contains high levels of sediments or hydrocarbons which could clog outlets might need pre-treatment through the use of other techniques like water quality inlets.

Inlet protection devices:

These are also called hydrodynamic separators. They are flow-through structures that feature a separation or settings units for removing grease, oil, trash, and so on. This technology can be used effectively for the pre-treatment of the other varying inlet protection devices. They are very commonly utilized in potential stormwater areas. And these areas are the ones that always feature significant high pollutant concentrations.

Permeable pavement:

These boost the recharge of groundwater considerably. Some of these pavements are used in creating voids on all the corners of the used pavers. Concrete grid paver systems are the ones made from concrete blocks. They are used to generate voids inside the blocks, and this is done by cleaning out any fine particles that might happen to be inside them.

These are some of the ways by which you can enhance your stormwater management plan or strategy, but they are not all there is. There are several others. Just use anyone or a combination from the list and you will certainly see positive results for your efforts. But if you need any assistance with your next green construction project, you can always contact experts and seek their help.
