Because parking lots, driveways and structures are less permeable than natural surfaces, property development leads to run off problems: excess water in certain areas causes flooding and increased flow rate, which in turn leads to increased erosion.
Because parking lots, driveways and structures are less permeable than natural surfaces, property development leads to run off problems: excess water in certain areas causes flooding and increased flow rate, which in turn leads to increased erosion. Man-made surfaces also lead to reduced water quality through contamination, a problem the developer is then responsible for solving.
Part of developing is designing and installing runoff management and treatment systems. The problem is that they take up usable space. If you already have limited space, due to property being expensive or unavailable, you can maximize the usable space by putting your retention system underground. The above ground area can then be used for structures, driveways, or parking.
Construction and design
The containment chambers used to hold runoff in underground systems can be made into any practical size and shape, so they can fit into almost any space. Available materials include steel, aluminum, concrete, and synthetic materials like plastics. The appropriate material will be determined by the design parameters, like whether the containers will be pipes, rectangular tanks, or some other shape.
Is it right for my project?
Due to an intensified engineering and construction process, underground retention ponds yield a larger price tag. But these costs are covered, and then pay back, in some situations. The installation costs need to be weighed against the costs of acquiring more real estate and the risks of flooding. Just as important is the upside of maximizing your usable property as value-added space. If you can use it for parking, production, or retail, you/re making money off that space.
