REHAU's high specification sewerage pipes have been chosen for a diversion installation on the Thatchers Cider factory site in Sandford, Somerset.

REHAU's AWADUKT HPP SN16 250mm pipework was requested for the installation by Wessex Water because of its outstanding durability and strength. The diversion of sewerage required on the Thatchers site, meant that the pipework would be laid underneath where a new building is to be constructed, so Wessex Water needed a robust solution which would be up to the challenge.

The AWADUKT HPP SN16 is the strongest sewerage pipe on the market, with a minimum ring stiffness of 16KN/m3. It has high static and dynamic load bearing capacity, so is ideal for applications such as those used at the Thatchers factory. For added peace of mind, it comes with a 10-year manufacturer's warranty and it has a 100-year service life (as certified by the LGA Nuremberg).

The 220 metres of pipework required for the sewerage diversion in Sandford was carried out by contractors Dancourt Construction. Including excavation works, the diversion took just three weeks to complete.

Matt Reay from Dancourt Construction said: "This was the first time we'd used REHAU's AWADUKT HPP sewerage pipes and we were very impressed. Considering how strong the pipes are, it was remarkably light and easy to install, largely because cutting the pipe and joining it was so straightforward. Thanks to the success of the Thatchers installation, I'm sure Wessex Water will be keen for us to use it again on other jobs where a similarly robust and durable solution is needed."

REHAU's heavy-duty sewerage pipes - available in 1m, 3m and 6m lengths - also feature unique COOL COLOUR Technology, which uses infrared reflecting colour pigments to reduce the heating of the pipe should it be exposed to sunlight.

Understanding that high quality pipes require joints to match, REHAU's AWADUKT HPP SN16 can be fitted with a safety-lock sealing system to ensure seals are not accidentally pushed out during connection, and that the installation is sound enough to be used in water protection areas (II and III). The pipes and joints have also earned the IKT seal of approval to show they are impermeable to external water getting into the system too.

As well as being built to last and easy to install, REHAU's AWADUKT HPP SN 16 sewer pipe systems are also very sustainable. The SN16 has achieved Cradle to Cradle certification with Gold status, ensuring it is made and recycled in accordance with the principles of an endless, ecologically healthy cycle. For example, the production of the pipes generates very low CO2 emissions or other greenhouse gases as it is made in a factory where extrusion lines are operated by 100 per cent green electricity. And at the end of its lifecycle, the pipe material can be wholly recycled and reused to make new pipes.

Steve Richmond from REHAU said: "40 years of experience in polymer processing has gone into the design of our AWADUKT HPP heavy duty sewer pipe systems, to ensure they are up to the toughest challenges our customers are faced with. They can be used under extremes of pressure and load, without compromising on performance, and are becoming increasingly popular in municipal drainage, transport terminals, industry and - like the Thatchers site - where they will be laid underneath a building. They are the most robust sewerage pipes on the market, and our customers can fit and forget them, safe in the knowledge that they will stand the test of time."
