Surface Water Drainage Systems

Domestic and Industrial

Surface water drainage systems transport rainwater away from gutters, patios, driveways, roads and fields to prevent flooding. Surface water drain pipes normally discharge to a watercourse or indirectly into the groundwater via a soakaway.

Types of drainage

Hepworth Type Drainage Gully
Drainage gullies are the most common means of surface water collection. Positioned at the lowest point of the surface, which on a driveway is often slightly ‘dished’ these hoppers vary in size and design depending on requirements. Pictured above is clay gully with a cast iron grid suitable for heavy vehicle usage, however for a domestic driveway, plastic units are usually suitable.

Grates are always removable to remove debris from the bottom of the gully which can be connected to an existing storm drain, or linked to a SUDS (Sustainable Urban Drainage System) for natural dispersion by gradual infiltration.

ACO Channel Drains
Ideal for large surface areas, ACO channels are the perfect solution to prevent water ingress through the full width of a garage entrance, or to prevent surface water from your property entering the public highway, thereby complying with council planning laws.

Available with plastic, galvanised steel or heavy duty cast iron gratings, ACO’s are extremly versatile and suit many applications.

‘French’ Drains – Slip Trenches
Ideal for where water run-off can be directed by means of a definate incline or camber, a French drain can be dug from the soft ground surrounding a solid surfaced area (a lawn for example).

These trenches are often left open or infilled with gravel depending on the environment and location.

Soakaways
A soakaway system is a means to release collected surface water slowly into the earth. For an average driveway the soakaway may be excavated to approximetely one cubic metre, infilled using ‘single sized’ stone, and capped off with concrete.

Surface water will fill the gaps between the sones and disperse naturally. This type of ‘SUDS’ system must be constructed 5 metres or more from any buildings, (BS 8301) be lower than the point of collection, and not be deep enough to disturb the water table.
