More than ever before, the construction of water supply networks is about sustainability, not only in terms of service life, but also in terms of the design of the various components.
When it comes to the sustainability of AEP networks, Elydan has positioned itself as a company supplying pipes perfectly adapted to meet these challenges. This article, written in collaboration with Marc PALOMARES, Elydan's Technical and Innovation Director, shows just how.

PE100 RCD is a new-generation material that combines all the advantages of PE100 RC and PE100 RD polyethylene.
In concrete terms, our TEC 1 RCD AEP is highly resistant to severe disinfection conditions (high concentrations of chlorine, chlorine dioxide, etc.) and high temperatures (RD). In addition, PE100 RCD offers very high resistance to slow crack propagation, and allows the reuse of existing materials for backfilling trenches - without sand encapsulation (RC).
Pipes can react with certain transported chemicals, which can compromise their structural integrity over time or shorten their service life.
Polyethylene PE100 RCD networks are insensitive to a very large number of chemicals, making them highly durable, especially for industrial applications.
This PE capability allows our products
💠 increased durability
💠 reduced maintenance
💠 improved safety
💠 installation flexibility.
Installing polyethylene pipes means choosing peace of mind.
PE100 RCD pipes offer significant advantages over traditional materials in terms of resistance to slow cracking. PE100 RCD offers excellent resistance to the propagation of stress cracks, considerably extending the service life of piping systems.
PE pipes absorb and dissipate forces, reducing the risk of cracking.
Another important advantage is that, thanks to their high mechanical strength, our PE1 RCD pipes can be covered over by alluvial soil. This saves time and money.
This resilience translates into lower maintenance costs and fewer service interruptions, making PE pipes particularly suitable for industrial and infrastructure applications where long-term reliability is crucial.
Because of the presence of joints, mechanical connections can become a weak point, particularly in the event of ground movement, inadequate installation conditions or operating conditions (water hammer), leading to leaks. These are very common conditions.
Polyethylene PE100 RCD networks can be welded by electrofusion or mirror welding; deployed in long lengths or in bars, they reduce the risk of leakage to zero at each connection.
PE pipe networks are a choice that greatly reduces the risk of long-term leaks.
This is one of the most common problems affecting drinking water pipes.
⬇️La Corrosion can be internal, caused by water;
⬆️ou external, caused by moisture and acidic soils.
Corrosion inevitably leads to leaks or ruptures.
Polyethylene PE100 RCD networks are corrosion-proof and durable for over 100 years.

Over time, minerals and other substances in the water can build up inside the pipes, reducing their flow capacity. This can also affect water quality over time.
Polyethylene PE100 RCD networks are perfectly smooth on the inside, with no coating, thus limiting deposits and ensuring the right flow rate thanks to controlled head losses throughout their life.
By choosing PE100 polyethylene pipes TEC 1 RCD AEPpolyethylene pipes, you're opting for a reliable, long-lasting solution that guarantees optimum flow and exceptional chemical resistance, even in demanding environments.
Soil movements caused by seismic phenomena, but also by increasingly intense climatic and meteorological phenomena, can jeopardize the durability of underground installations. Fortunately, PE networks are adapted to these changes.
48% of France's territory is located in zones with moderate or high exposure to clay shrinkage and swelling (georisques.gouv.fr). Rigid pipes can be damaged by ground movements, despite their relative ductility. One of the many strengths of PE networks lies in their flexibility.
Drought, freezing and thawing of soils, shrinkage and swelling due to water flow, are all phenomena that do not worry PE pipe networks.
Polyethylene PE100 RCD networks are flexible and robust, making them highly resistant and adaptable even under extreme conditions, particularly in seismic zones.
PE100 polyethylene pipes are distinguished by their ability to absorb major deformations without suffering structural damage.
Numerous feedbacks from gas networks following earthquakes prove this (Kobé - Japan, Armenia - Colombia, L'Alquila - Italy, ...).
Today's local authorities are facing budget constraints, but they still need to continue investing to maintain water services for their customers.
Polyethylene PE100 RCD networks are a much more economical solution than traditional materials in terms of investment, and they are also much less expensive to run than older networks, thanks in particular to the reduction in pressure losses and consequent energy savings of around 15%.
No more need for concrete stops, locking joints, sand for backfill, or cathodic protection; the financial gain is real and immediate.
From a logistical and environmental point of view, PE is also a real ally: lighter and, above all, more flexible, packaging in 18m bars, coils and reels means much more linear space can be loaded by truck.
PE100 RCD, the material of the 21st century, is the best choice for economical, long-lasting installations.
