A twinwall polypropylene plastic pipe, laid in an excavated trench that has been backfilled, to move water under and away from the path.

Stone headwalls pipe culvert drawings the pipe ends and retain the pipe bedding and backfill materials. It is the commonest drainage feature used in lowland path construction. Pipe culverts are also used for pipe culvert drawings paths where a pipe is a practical way to channel large, fast flowing streams, and where there is no suitable stone available to build stone culverts or cross drains.

How does it work? The plastic pipe channels water from one side of the path to the other, from a ditch installed close to the path.

Pipe culvert

Stone headwalls are built around the ends of the pipe to hide it, but also to retain the pipe bedding and backfill materials, and to support the path edges, which would otherwise collapse over the pipe ends, stopping water getting into and out of the pipe.

What are the benefits? Path drainage features such as cross drains create physical barriers, making access for most path users difficult or impossible. Pipe culvert drawings culverts will not pipe culvert drawings barriers, as they provide a continuous path surface over the top of the pipe.

This is essential when a path is expected to be used by people on foot, wheels or horseback.

It is important to use the correct size pipe culvert drawings of pipe for the expected volume of water, otherwise the flowing water will spill over onto the path surface and damage it.

There are various methods to help you choose the right size: Make pipe culverts the same size as, or slightly bigger than, any existing culverts in the area that are working well. Speak to local people and land managers about known stream pipe culvert drawings ditch water levels.

Visit your path site in the wettest weather possible and determine the rate of discharge that the culvert needs to cope with. This can be quite a complex calculation, involving measuring the area and depth of any flooding.


Pipe culverts should never run full pipe culvert drawings ideally, they should be no more than two thirds full in the worst case water flow. For deep, slow moving ditches or streams, use a pipe size which is twice that of the watercourse's depth.

Twinwall polypropylene plastic pipe is available in various sizes - mm, mm, mm, mm, mm, pipe culvert drawings mm. For ditch systems, use several mm or mm diameter pipes set at regular intervals — every 10m to 20m depending on the amount of water flowing into the ditches.

How much will it cost?

How do you install it? Good locations for pipe culverts are: The lowest points in the side ditch beside the path.


Where flowing water will cross under the path via its own gravity. Where small streams or water springs flow across the path.

Where dispersal of water away from the path is easiest. On small streams, place pipe culverts on a straight section, preferably where water speed is likely to be low.

A trench was excavated across the line of the path. The trench must be long, wide and deep enough to take the required length and size of pipe, as well as compacted bedding and backfill materials. The bottom of the trench must be angled enough to provide pipe culvert drawings required fall.

Remove sharp stones which could puncture the pipe wall. Cut the pipe to the exact pipe culvert drawings required.
