The Environment Agency Culvert Policy sets out the guidelines of the Environment Agency relating to the use of culverts and maintenance of culverts. In this post, we take a look at some of the key areas of consideration. Read on for more information.

What Is a Culvert?

A culvert is a tunnel that carries a stream or open drain under a road or railway. They are typically used to carry water from one side of an obstruction to another. They may be made from a number of different materials, including pipe or reinforced concrete.

Environment Agency Culvert Policy

The Environment Agency policy states that a watercourse should not be culverted unless it is absolutely necessary. The reason for this recommendation is to maintain the quality of the water contained within the watercourse, to avoid risk of blockage and to improve access, which may be required at times when maintenance is needed.


A blockage in a culvert can be very difficult to remove. It is an extremely problematic issue that can pose a serious flood risk. As such it can require a great deal of maintenance to ensure that blockages do not form. For this reason, the Environment Agency suggests that the provision of a screen at the entrance of a culvert be considered.


In the event that a culvert is required, at Wrightfield, we have a range of products that can help to bring the culvert in line with the recommendations of the Environment Agency. This includes weed screens, gratings and grilles. These provisions can help to prevent the entry of debris, including weeds, rubbish and even animal cadavers.
