Drainage Systems.

Brava provides expert drainage and flood management solutions as part of our groundworks and civil engineering services, supporting residential and commercial projects across Bedfordshire and Hertfordshire. We install safe, reliable and UK-compliant systems to manage surface water, wastewater and stormwater effectively.

Our services include foul and surface water drainage, soakaways, attenuation tanks, permeable paving, and linear drainage channels, alongside sustainable solutions such as SUDS swales, retention ponds, and detention basins. We also deliver culverts, French drains, headwalls, outfalls, and flood defence measures to protect properties and infrastructure from water damage.

Whether for housing developments, commercial sites, or industrial projects, we combine expertise, compliance, and modern techniques to ensure every site is properly drained and protected from flooding.

Foul Water Drainage Systems

Safely remove wastewater from buildings to the public sewer or treatment system, using pipes and manholes built to UK regulations.

Surface Water Drainage Systems

Collect rainwater from roofs, paved areas, and highways, directing it to soakaways, watercourses, or attenuation systems.

Combined Sewer Systems

Older urban networks that carry both foul and surface water, used in areas with historic infrastructure.

Soakaways

Underground pits filled with stone or rubble, allowing rainwater to naturally drain into the ground. Ideal for small residential sites with permeable soil.

Attenuation Tanks / Cellular Storage

Underground storage units that temporarily hold stormwater and release it gradually, reducing flood risk on developed sites.

SUDS Swales

Shallow, vegetated channels designed to slow, store, and filter runoff, commonly used in housing estates, highways, and car parks.

Permeable Paving Systems

Paving that allows water to pass through into the ground or storage system, helping to reduce surface runoff on driveways, car parks, and pedestrian areas.

Linear / Trench Drainage Channels

Long channels with grates installed along roads, car parks, or around buildings to efficiently collect and divert surface water.

Retention Ponds / Detention Basins

Open water areas designed to temporarily store excess runoff during heavy rainfall, helping manage peak flows and reduce downstream flooding.

Culverts

Covered or underground channels that allow water to pass under roads, railways, or embankments, helping manage both drainage and flood risks.

Headwalls & Outfalls

Structures at the end of drainage pipes or channels to safely discharge water into watercourses while preventing erosion.

French Drains / Filter Drains

Gravel-filled trenches with perforated pipes to redirect water away from structures, commonly used around basements and low-lying areas.

Flood Defence & Riverbank Works

Embankments, revetments, gabions, and sheet piling designed to protect developments from river or fluvial flooding.

Rainwater Harvesting Systems

Collect and store rainwater from roofs for non-potable uses, reducing surface water runoff while providing an eco-friendly water supply.

Drainage, SUDS & Flood Management Services.

Brava provides a full range of drainage and flood management solutions for both residential and commercial projects, ensuring water is safely and efficiently managed on every site. From traditional drainage systems to modern SUDS (Sustainable Drainage Systems), our expert team delivers compliant, reliable solutions tailored to each project.

Our services include foul water drainage to remove wastewater, and surface water drainage to manage rainwater from roofs, paved areas and highways. We install combined sewer systems, soakaways, attenuation tanks, and permeable paving systems to control water flow and reduce flood risk.

We also provide SUDS solutions including swales, linear drainage channels, retention ponds and detention basins to manage surface water sustainably. Culverts, headwalls, outfalls and French drains are installed to protect buildings and infrastructure from water damage, while flood defence measures such as embankments, revetments, gabions and sheet piling safeguard sites in high-risk areas.

For projects aiming to combine sustainability with functionality, we also design and install rainwater harvesting systems, reducing runoff and providing an eco-friendly water supply for non-potable uses. Whether for new housing developments, commercial sites, or large infrastructure projects, our team delivers UK-compliant drainage, SUDS, and flood management solutions across the Home Counties and within a 40-mile radius.
