Attenuation crates and construction
Attenuation crates store surface water and release it slowly to reduce peak flow to the drain or watercourse. They are often specified on new developments. We install attenuation systems to design with the correct storage volume and flow control.
The commercial value of resolving attenuation crates and construction early is fewer delays, clearer budgeting, and reduced repeat disruption.

When to consider this guidance
Teams usually investigate attenuation crates and construction when early warning signs start affecting reliability, compliance, or project timelines. This is often the point where decision makers move from observation into scoped technical action.
Signs and common situations
- Planning or design requires attenuation
- Storage volume from drainage design
- Crates with geotextile and connections
- Flow control orifice or chamber
- Adoption or maintenance agreement
How this is usually carried out
We work from your drainage engineer's design. We install the crate system, connections and flow control.
If this matches your project stage, send drawings and site details for a scoped quote — or call to talk through programme and access constraints.

We deliver attenuation to design with commissioning. We provide as-built and handover for adoption if required.
What affects cost and complexity
Cost and complexity usually depend on access constraints, total scope, existing condition, and whether related works need to be coordinated in the same programme window.
