Stormwater is the product of significant precipitation (rainfall) and snowmelt, and it soaks into the ground in most cases. However, this isn’t always practicable, in which case surface runoff is referred to. It is a problem since stormwater can raise water levels, resulting in flooding and environmental harm. As a result, if stormwater is contaminated with chemicals, germs, or something worse, such as sewage, it can lead to pollution and the spread of water, which can have serious consequences and threaten human life.
Therefore, it is important to use stormwater pits technologies to gather and store surface runoff and filter and purify the stormwater so that it may be kept and reused. Stormwater harvesting is a core use of stormwater management technologies that allows a specific metropolitan region to become self-sufficient in water usage.
What Is the Purpose of Stormwater Management?
As changing climate has become even more of a concern in the UK (as evidenced by recent flooding in the south of England), regulatory controls and requirements to make urban areas stormwater-ready have been implemented – also known as Sustainable Urban Drainage Systems (SUDS). Schedule 3 of the Flood and Water Management Act of 2010 spells forth the goals and reasons why stormwater runoff must be handled safely and efficiently:
- Mitigating the effects of flooding
- Improving the quality of water
- Environmental protection and improvement
- Keeping people’s health and safety in mind
- Ensure drainage systems are stable and long-lasting
Stormwater Management Solution Types
So, to safeguard people and the environment, various stormwater pits technologies are utilized throughout the developed world, particularly in urban areas. Installing underground tanks and pipelines for storage and drainage is one of them. However, because of the digging of the earth and other factors, these can be costly undertakings that require a lot of work.
Underground stormwater infiltration tanks are one alternative to these technologies. During times of high water, these hold water and slowly release it once the levels have dropped. It reduces erosion in rivers and other natural waterways. Drainage and Stormwater Management is one of the challenges that arise with urbanization in densely populated places. Stormwater is water that collects due to precipitation, but it can also come from melting snow. Surface runoff occurs when the ground does not absorb rainfall.
Unlike the traditional approach of installing an entire network of plumbing, the stormwater boxes can be placed with as few as two groundworkers. Excavating on the ground and layering geotextile fabrics before stacking the boxes together in a grid configuration until the appropriate system size is established is how the installation is done. The pipes are linked to the ground, the tank is covered with extra geotextile fabric, and the box is filled. That is all there is to it.
