Six Ways to Enhance Stormwater Management

A rain garden or a bioretention cell is a depressed area containing a backfill that is porous under a vegetated surface. Often, these areas have an underdrain to encourage infiltration as well as filtration, especially in soils that are clayey. Bioretention cells provide pollutant removal, groundwater recharge, and runoff detention. They are an effective solution in urban areas or parking lots, where green space is limited.

Gutter and curb elimination

Gutters and curbs transport flow really fast to a stormwater drain without allowing for pollutant removal or infiltration using an inlet filter. Eliminating gutters and curbs can reduce runoff volumes and increase sheet flow. Maintaining sheet flow by removing gutters and curbs that direct runoff into bioretention basins and swales that are vegetated helps to prevent soil erosion by stormwater also helps retain hydraulic conditions (pre-development). A level spreader, which is a channel designed to transform concentrated runoff into sheet flow and distribute it uniformly across a slope, may also be included in order to prevent soil erosion.

Grassed swales

They are shallow outlets covered with grass that help to slow down runoff while facilitating infiltration. The sustainability of grassed swales depends on soil type, land use, imperviousness of the watershed that is contributing, and the slopes and the dimensions system of grassed swale. Grassed swales can be used to manage runoff from the drainage areas that are less than four hectares in size. It is encouraged that you use natural areas that are low-lying and drainage courses that are natural should be utilized.

Green parking design

These, when applied together, reduce the contribution of the parking lots to total cover that is impervious. Green parking lot design techniques include minimizing the dimensions of parking lot spaces, setting a maximum number for parking lots of spaces, utilizing alternative pavers in overcrowded parking areas, making use of bioretention areas to treat stormwater and incentives for structured parking.

Infiltration trenches

They are rock-filled trenches without any channels. These trenches collect runoff when there is a storm and release it into the soil through infiltration. These trenches maybe used in conjunction with the other devices meant for infiltration of storm water using an inlet filter. This will provide peak flow attenuation as well as the quality control of water. Runoff that contains high levels of hydrocarbons or sediments that may clog the outlets may need to be pre-treated using other techniques such as water quality inlets.

Inlet protection devices

These are also known as hydrodynamic separators and are flow-through structures with a separation or a settling unit to remove oil, trash, grease, etc. You can use this technology for the pre-treatment of the other inlet protection devices. They are commonly used in the potential stormwater areas, where there is a high concentration of pollutants.

Permeable pavement

They promote the recharge of groundwater. Some pavements are used to create voids on the corners of the pavers. Concrete grid paver systems are made of concrete blocks, which are used to create voids inside the blocks, by clearing the finer particles inside them.

6 Green House Considerations

Because of the many environmental concerns, threats and considerations, many buyers, as well as homeowners, today, have become more – and – more concerned with various factors, often referred to as green real estate. There are many considerations, and variations, as well as degrees of greening individuals are interested in. Some (however a minority) are real environmentalists, and want their home, to exhibit their concern and attention, to this very important issue. Others merely want to proceed in a somewhat balanced manner, and want to include reasonable green characteristics. This article will be a basic one, and discuss, in general terms, 6 considerations, regarding making your home, a greener one.

1. Windows and doors: Obviously, energy conservation is a major environmental concern. We often speak about a business’ carbon footprint, but, obviously, certain houses are far more energy – efficient than others. When were your windows replaced and/ or upgraded, and are they efficient? Do they keep out most of the cold, in the winter, and minimize the amount of heat, which enters in the hottest weather? What materials are your windows and doors, made of? Do your doors leak? Begin by having someone do an energy inspection, and see if you are losing much heat, because of inefficiencies. Doors can often be made more efficient, by having them re – hung, and putting a properly installed, sweep, on the bottom of the door. How much money, and energy are you wasting?

2. Solar, geo – thermal, etc: Some houses are candidates for solar panels, while others are not! What direction does your roof face? Are there any large trees blocking your roof? How many hours a day, of sun, does your roof, experience? Have you had your home examined, to discover whether you might be a good candidate for geo – thermal? This often requires a combination and evaluation of your property, pitch, location, and layout.

3. Energy – efficient burners/ boilers, and air conditioners: When was the last energy efficiency evaluation, you had performed? How old is your burner/ boiler, and is it efficient? What type of air conditioning do you use, and what it the Energy Efficiency Rating?

4. Roof: Light – colored roofs reflect heat, while darker ones, absorb it. Therefore, doesn’t it make sense, that warmer climates should use lighter ones, and colder ones, darker? What is the material being used? Is it efficient, effective and safe? How old is the roof?

5. Insulation: What is the rating of your insulation, and how well insulated, is the house? Have the walls (especially outside ones) checked, for efficiency? Older houses tend not to have updated insulation, or may contain less than the safest materials. An ounce of prevention, makes lots of sense!

6. Materials: Are you using safe, sustainable materials, in your house? This is generally more relevant, in newer houses, or extensions, but if you are concerned with the environment, you should consider the sustainability, safety and impacts of your home!

There are numerous environmental considerations. Whether you are truly committed to the environment, or merely want to be responsible, and save money (and be safer), it makes sense to think green!
