After heavy rain, water can build up in gutters, driveways, and open spaces, creating a flood-like situation. If excess water is accumulated in drains, then it can cause the pipes to burst with excess pressure. And, in worse conditions, it can cause flooding leading to excessive damage to public and private assets. To avoid it, every residential project must comprise a stormwater attenuation system.
Stormwater attenuation tanks are useful in storing, capturing, and storing excess rainwater, thereby avoiding water logging or flooding. Used in both commercial and domestic projects, they provide a natural way to groundwater infiltration. Due to being simple, cost-effective and easy to install, they have become an everyday item found in almost all types of construction projects. Unlike natural soakaways, which are essentially a hole dug into the ground and filled with pebbles, stormwater attenuation tanks are durable cylindrical-shaped structures made up of plastic or cement.
These tanks are installed below the ground and comprise outlets to divert water slowly into the main drainage system. The tanks are covered by a durable surface on the top which can withstand up to 80-tonne vehicles.
Stormwater attenuation system rests on the ability to capture floodwaters, before releasing it slowly into their natural drainage pathways. Therefore, it must comprise an elevator that elevated the level of the ground and creates a space in which the floodwater can be accumulated through a tank. The tank is generally 2.5 m deep but can be customized to fit large-scale demand.
In some cases, stormwater attenuation tanks can be used along with soakaway crates to capture water and store it elsewhere. And, a separate tank can capture water from a very wide area using connected pipes.
At Carlo Concrete, we have the requisite products and staff to help you build a proper stormwater attenuation system.
