Securing planning permission for residential extensions often requires a clear strategy for managing surface water. Nimbus Engineering recently worked with a homeowner in Oxford to deliver a fully compliant SuDS Report and infiltration testing, ensuring their proposed single-storey extension met all local authority drainage requirements.

Attenuation tanks are a key component of Sustainable Drainage Systems (SuDS), designed to manage surface water runoff in a controlled and sustainable manner. Their primary purpose is straightforward: to temporarily store excess rainwater and release it slowly, helping to prevent flooding and reduce pressure on [...]

Permeable paving is a type of hard surface that allows rainwater to pass through it rather than running off into conventional drainage systems. As an important component of Sustainable Drainage Systems (SuDS), permeable paving helps manage surface water at the source, reducing flood risk, improving [...]

A swale is a shallow, vegetated channel designed to manage surface water runoff as part of a Sustainable Drainage System (SuDS). Swales provide a natural alternative to traditional underground drainage pipes by slowing, storing, filtering, and conveying rainwater across a site. Widely used in modern [...]

A raingarden is a shallow, planted feature designed to capture, store, and treat rainwater runoff close to where it falls. As part of Sustainable Drainage Systems (SuDS), raingardens help manage surface water in a natural and sustainable way. They can also improve the visual appearance, [...]

One of the most common questions from developers, homeowners, and planners is whether SuDS are expensive to implement. On the surface, Sustainable Drainage Systems can appear more complex than traditional drainage systems. However, the real answer depends on how SuDS are designed, when they are [...]

Surface water flooding is one of the most common and disruptive forms of flooding in the UK. It typically occurs when heavy rainfall overwhelms drainage systems, causing water to flow across roads and gardens and into properties. Unlike river flooding, surface water flooding can happen [...]

In construction, success isn't defined solely by the buildings themselves — it's also shaped by how the surrounding land is designed and integrated. External levels design, a core element of civil engineering, plays a crucial role in ensuring developments are functional, accessible and resilient. At [...]

Why Below-Ground Drainage Matters Below-ground drainage systems are responsible for safely managing wastewater and surface water across a site. When designed effectively, they protect buildings, infrastructure, and surrounding environments from flooding, waterlogging, and contamination. Poorly designed systems, on the other hand, can lead to costly [...]

Why Discussing SuDS at the Planning and Site Design Stage Is the Smartest Move Sustainable Drainage Systems (SuDS) are no longer a “nice to have” feature in development — they are an essential component of resilient, future-proof design. Yet, too often, SuDS are treated as [...]
