Storm water is that portion of the rain or melted snow that falls on the ground and requires removal so that it does not lead to waterlogging or flooding of any residential areas. Storm water, if not managed adequately can lead to problems with safety, health issues, and environmental concerns. This is where the proper installation and management of residential storm water drainage has to be given high importance.
Residential storm water drains can consist of a series of pipes buried under your property and designed to catch and retain excess water after rains. It can also be in the form of drains, pipes, and layers of gravel to absorb the runoff. It is not correct to allow sewer systems to handle this excess water, as at times, during storms, the runoff can be high, and lead to sewers overflowing and leading to unhealthy conditions all around the home. There could then be problems for not only the homeowner but the community in general. If your yard or area around your home gets muddy after even a slight drizzle, you will need to look at installing a proper drainage system for the stormwater.
Proper drainage of stormwater can help to protect your landscape and all the plants and lawn that you have so painstakingly planted and nurtured. Excess water in gardens can lead to plant diseases and damage to shrubs and flowering plants. Water around your home for long periods of time can lead to the weakening of foundations and lead to a settlement that can act to damage the structure of your home. When the flow of water is excessive and unmanaged it can erode the land.
To start the building of a proper drainage system for the stormwater, study the lie of your land, and the catchment area it serves that brings in stormwater. If this build up occurs before your property you may need a cut off drain at the perimeter of the property to trap this outside water before it enters your area. This can be in the form of raised walls that divert the water or drains to trap and lead the water to other city drains. On your own property, you need to understand how the rainwater accumulates and flows so that you can train it to be led away to the desired outlets. You can create channel drains, permeable paths, and pavers, or gravel beds that can absorb the rainwater. You will need to pay attention to runoff from gutters on roofs.
Once all the water is collected, you must study the existing city stormwater drainage systems and see how you can link up to them, so that the excess water gets adequately removed. In most cities, before you start building on a property, you will be informed about the main stormwater drainage installations adjoining your property to which you will have to direct the water that you collect in your residential stormwater drainage system.
In natural settings runoff from stormwater gets partly absorbed in the ground, while the excess finds its way to the nearest stream or river. In urban settings, the high incidence of areas that are covered by impervious material leads to a greater amount of excess stormwater that does need disposing of. The scarcity of water and it’s being a limited resource has led to many communities insisting on rainwater harvesting, in which stormwater drainage is led into tanks within a property and stored for use in gardens and washing.
Residential stormwater drainage systems require careful management and make for a critical aspect in any urban projects, and can greatly help in managing scarce resources, while at the same time ensuring flood control management.
