An interceptor drain, also known as a curtain drain, is a drainage system that is installed to collect, channel and remove surface and subsurface water within permeable soil as it flows across an impermeable soil layer.
The types, location and functions of surface drainage are as follows: Interceptor Drain Interceptor drains are located along the uppermost edge of cut slopes where the cutting begins, and along the edge of the cut slope descending towards the lowest point of the natural watercourse to collect water from upstream of interceptor and from bench drain.
Aug 2, 2023 · What is a Drain Interceptor? A drain interceptor is a term which can be easily confused. The first use of the term is for an interceptor trap, a device which was introduced widely during Victorian times as a means to prevent the spread of airborne diseases.
Apr 6, 2017 · A drain interceptor is a tank installed within pipework to collect and hold contaminants, allowing the remaining wastewater to be discharged safely into the main sewerage system. Drainage interceptors are referred to by other names, including interceptor traps, interceptor tanks, and filter tanks.
Jul 26, 2023 · To ensure proper drainage of cut and fill slope surfaces, surface drains must be installed both at the top and downslope areas. In addition to the normal interceptor drains at the top of the slope, cascade drains with handrails should be provided to facilitate future maintenance.
Interceptor drainage is a term used to describe how tile captures water as it moves down slopes in the subsurface. For a drainage tile to be an interceptor drain, it must be placed perpendicular to the flow of water, or more generally perpendicular to the rising slope of a field.

Collector drains generally provide temporary storage for ground water before being expelled into a safer place away from the house. Interceptor drains, on the other hand, capture water runoff on the surface before it reaches vulnerable structures such as a home’s foundation.
• Interceptor drains that aim to remove flows from a particular soil stratum or an aquifer should clearly penetrate the stratum and should extend to a depth of 150 mm to 300 mm into the impervious strata below. • Where the subsoil drain is intended to lower the general groundwater level, the determination of the
Interceptor drains are used to remove water as it seeps down a slope to prevent the soil from becoming saturated and subject to slippage. They are installed across a slope and drain to the side of the slope.
