Surface Water Drainage Systems
Domestic and Industrial
Types of drainage
Hepworth Type Drainage Gully
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
Available with plastic, galvanised steel or heavy duty cast iron gratings, ACO’s are extremly versatile and suit many applications.
‘French’ Drains – Slip Trenches
These trenches are often left open or infilled with gravel depending on the environment and location.
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.
