Replacement: BS EN 12201 replaced BS 6572 and is the latest standard for plastic pipe systems for water supply. However, in some circumstances, pre-laid ducting is often installed by the groundworker to allow for MDPE pipe to be installed at a later date. Your duct system may also need duct access chambers depending on your project, which come in a various sizes to suit.

Some water authorities allow MDPE to be laid at a shallower depth, depending on circumstances, but must be insulated; check local water authority guidance. It is intended for the underground distribution of potable water and is constructed from MDPE material, commonly known as alkathene, to ensure long-lasting use and resistance against corrosion. Check with your local water authority before using for potable drinking water as blue MDPE may be required.Water caution marker tapes are commonly used as additional indications, alerting presence of the pipes. In the UK, 25mm MDPE is the standard size of new water supply pipe for domestic properties, however, if less than 40m of continuous below-ground water supply pipe is required, check with local water authority specifications for your project as certain areas may vary. A duct is designed to protect the pipe from damage and alert others to the presence of duct in the ground. Also suitable for hydroelectricity schemes, geothermal pipework, irrigation, aquaculture, marine outfalls and many other projects.

Consult WIS 4-08-01 for details on bed and fill materials; in some instances MDPE may be laid directly onto the trimmed trench bottom where the soil is uniform, fine grained and free from large stones and flints. The light blue indicates this is suitable for below ground potable (drinking) water mains supply distribution, popular for both domestic and commercial properties. Our Blue MDPE pipes are used for the transportation of above ground and underground clean water supplies MDPE is the ideal solution for new installations, pipeline replacement, and rehabilitation.Drawcord must be inserted into the ducting and gas marker tape must be laid at a minimum of 75mm above ducting to avoid future interference, and may include tracer wire.
