Foul and Surface Water Drainage Installation

Foul and Surface Water Drainage Systems

We deliver complete drainage installation packages for:

• Housing developments (plot drainage)

• Roads, car parks, and industrial yards

• Schools, care homes, and public facilities

• Commercial units, depots, and retail parks

Systems include:

• Foul drainage: 110mm–225mm pipes to public sewer or treatment plant

• Surface water: 150mm–1200mm+ pipework, channels, and gulleys

• Soakaways and crate systems: for SUDS compliance

• Outfalls and headwalls: for discharge into ditches or swales

• Attenuation tanks: to control peak flow discharge

Installation Process

Our experienced drainage teams carry out full installation from excavation to backfill, including:

• Setting out levels and falls using laser and pipe lasers

• Trenching with tracked excavators or mini diggers

• Pipe bedding and surround using shingle or stone

• Pipe laying and jointing (uPVC, clay, twinwall, concrete)

• Backfilling in layers with compaction

• Gully and inspection point installation

• Reinstatement of surfaces where required

All drainage runs are constructed to meet building control, NHBC, and local water authority requirements.

SUDS-Compliant Design and Drainage

Modern drainage systems often require sustainable features to meet planning conditions and water management regulations. We install:

• Permeable base layers and filter drains

• Swales and ditches

• Perforated pipework

• Flow control chambers and orifice plates

• Soakaways and infiltration trenches

We can work with design teams or install to pre-approved SUDS drainage drawings.

Drainage for All Ground Types

Our drainage installation service includes options for:

• Greenfield developments

• Brownfield and remediated sites

• Confined urban plots

• Heavy clay or wet ground

• Deep drainage or overpumping

We can stabilise trench walls or provide trench boxes where required, and use pumps or diversions in waterlogged conditions.
