Frequently Asked Questions
Why do you need attenuation ?
Attenuation offers a lasting remedy for mitigating the risk of flooding resulting from water runoff during extended periods of rainfall. These systems incorporate a flow control chamber designed to regulate the volume of water discharged into a nearby sewer system or watercourse, such as a river or reservoir.
How close can stormwater attenuation system be to a building?
Unlike a soakaway system, underground floodways can be positioned much closer to a building. The critical consideration is ensuring that the building load or foundation load does not impact the tank. Ideally, if you were to draw a 45-degree angle from the foundation, that line should not intersect the tank. However, this may vary depending on the depth of the tank. Nonetheless, they can be situated in proximity to the building.
What are critical factors to consider with stormwater?
The main factors to check out to choose the best system for your project are :
- Stormwater System Application
- Sizing
- Footprint
- Cover Depth
- Base Preparation
- Stormwater System Construction Equipment
- Backfill
- Product Material
Stormwater System Total Installation Cost
How do flood tunnels work ?
An underground floodway channels surplus flood or stormwater from the surface into subterranean tunnel facilities. Constructed incrementally, these flood tunnels are situated in regions where river channelization is impractical due to existing urban infrastructure.
How does attenuation work?
Attenuation serves as a straightforward system for storing excess water, receiving water from various inlets like pipes and channel drains while typically having a single outlet. Acting as a void, the tank allows water to accumulate, preventing downstream drains from becoming overwhelmed during heavy storms. The outlet usually incorporates a flow control device, such as an orifice plate or vortex flow control, to regulate the discharge rate of water. Tank size is determined based on factors such as rainfall, surface area, and considerations for climate change.
Properly designed tanks should consistently accommodate the site’s water volume.
