Street and stormwater drainage systems provide vital services for keeping our streets, homes and communities protected against the worst of the wet weather. Among all types of constructions used to control runoff water, stormwater pits are one of the most successful and widely applied. It can sound like a daunting task to undertake a stormwater pit but is one of the simplest procedures if well executed can help in draining excess water effectively to help prevent flooding occurrences.
In this blog post, we’re going to walk you through the process of how to install a stormwater pit, as well as other crucial information you’ll need regarding the purpose of such a pit, legal requirements regarding the installation of the pit as well as how the installation process is undertaken.
To proceed with the installation process, it will be helpful and necessary to understand what a stormwater pit is and how it functions.
A stormwater pit is thus a system that has been designed with the main role of capturing stormwater and conveying it to a designated drainage system. Stormwater pits are normally placed in the ground and they receive water that has formed on roads, driveways as well as other hard surfaces. They assist in directing the water into the stormwater royals where there it safely transports it away from estates or business premises.
Usually, stormwater pits are also of different sizes based on the area of coverage with concrete and the amount of water expected in the pits at any one time. Some of the stormwater pits are of small size and are used for housing estates while others are larger to contain the stormwater supplements from a number of buildings within neighbourhoods or business districts.
A stormwater drainage system is incomplete without the stormwater drains. They are conduits that are intended to convey or direct stormwater from the pit to a drain or a river, lake or stormwater retention pond. These drains play various roles of mitigating or assisting in controlling water in places that can cause local inundation, or cause soil erosion or even destruction of structures.
Stormwater pits and proper drain installation involve a lot of planning, utmost care in installing, and, possibly, extensive knowledge of local laws. This is a cumulative process, which entails evaluating the site to selecting and placing the right kind of materials.
As a precursor to the construction of your stormwater pit, there must be a site survey conducted. This covers an assessment of the property to establish where the pit should be made, the rate of water flow and how to ensure that underground utilities such as gas or electrical are not distorted.
Once the location of the stormwater pit has been determined, the next thing is to lay out the entire drainage network.
The following procedure is to prepare the ground for the pit in which the stormwater is to be collected from the rooftop. The depth and size of the excavation will depend on the system which has been planned by you. Installation requires attention to avoid impact on underground utilities and to be certain the system will fit correctly in place.
For deep pits, you will need heavy working equipment like excavators or backhoes for the pits. He added that for the small residential pits, the operator could use only a shovel or mini-excavator. There must be assurance that the excavation will be to the right depth as well as the pit must be level.
Perhaps the stormwater pit could be formed after the excavation is done maybe during the construction of the pit. The majority of stormwater pits are constructed from concrete, plastic or other more resistant materials required to hold or transport water. The pit should be situated according to the point of lowest elevation in the excavated area for water harvesting.
Once the pit and drainage pipes have been well installed, then the excavation site should be refilled with soil, gravel and or any relevant materials. Pay specific attention to the fact that the backfill settles over time and make sure it is compacted. When backfilling is completed, then turn on the pipe to run water through the stormwater pit to check if the system is functioning properly or not.
Getting a stormwater pit should not be an easy task, especially when it comes to large-scale systems or complicated premises. These residential pits can, however, be installed by the homeowner provided that the homeowner hires professionals so that the job can be well done and with adherence to the set code of regulation.
Putting up a stormwater pit involves some key procedures, which ought to be followed carefully. Let’s break it down:
Stormwater pits are structures that hold water runoff for a brief while and then drain the water safely through the use of drains to a water course or stormwater holding pond. In its simplest form, the primary responsibility of a stormwater pit is to hold water that flows over rooftops, roads, and driveways. This water is then channelled by drains or channels directly into this pit.
Stormwater pits are usually served by stormwater drains that lead the water to other parts of the structure where it is to be discharged. It can be discharged slowly or treated before being let into a water source in its surrounding region.
In many places, you will need planning permission to place a stormwater pit installation. There may be state or local ordinances by a particular local council or municipality that you should take full advantage of before the installation. While stormwater system installation might not need permission, there might be other legal considerations that one is bound to, say the stormwater system should not affect other properties in a given neighbourhood.
Installing a stormwater pit is one of the most appropriate measures to control excess water in the event of a downpour. If you are in commercial real estate or managing a few properties, it is crucial to identify the different installation methods and legal contexts surrounding your HVAC system.
Always ensure that you give priority to these steps by consulting professionals where necessary, and ensure lots of awareness on the functions of your stormwater pit, which will go a long way in increasing the drainage systems of your compound, and therefore avoiding cases of water damages as well as flooding in your compound or your neighbour’s compound.
