There’s always the possibility that a faulty stormwater drainage system will cause problems for the homes and businesses surrounding it. One of the reasons these drainage designs are so unpredictable is due to the fact that new buildings are built or added to, landscaping in close proximity occurs and both of these actions (plus a host of others) can negatively impact what was once a very effective drain design. As a result, it’s important for building owners and home owners to take matters into their own hands when dealing with two surfaces that they can generally control – the rooftop and the street.
In this article, I am going to talk about those two sections and how they can be improved to stop the rainwater from ever getting to the drains – more accurately, how to cost-effectively reduce the amount of runoff so that the drains are able to work properly even if their design has become outdated based on the new additions to the area.
Protecting your home (or even corporate office building) from water is important and when a drainage system is not properly designed it can have negative effects on the health of the roof as well as the way water drains throughout the rest of the property. There are two effective methods that both generally work depending on the feasibility and design of each individual home owner’s roof (for large building structures, I generally the weir-system because it’s the least expensive for many customers).
By using weirs on top of a roof, these little contraptions are designed to retain stormwater by creating ponds of water that are contained for certain periods of time before being released – this is the most cost-effective method and can also be helpful in the summer as the design works to reduce air conditioning usage through the cooler temperature of the rooftop.
A green roof is made up of a ecologically-sound plant-spread, sitting in a very absorbent soil system that can retain a lot of rain water while helping to absorb air and noise pollution. In addition, many larger cities are offering tax breaks for people who implement green roofs at an average rate of $3.72 per square foot of green roof.
There are many effective ways to curb runoff water in the street and many cities are taking green initiatives in this movement. One way is to create clusters of trees that are planted with the intention of absorbing as much water as possible due to the specific nature of the soil and other vegetation surrounding the base of the trees.
It is very important (and easy, might I add) to create these tree clusters because half an inch of rainwater can produce 3,000 gallons of runoff that will most definitely affect any city street or even residential neighborhood. In tree clusters roughly 5×20, they are usually able to gather nearly 900 gallons of stormwater runoff, an effective use of scenery that can be implemented on a city block just as easily as a residential area.
