Barrier Pipe FAQs
What is a Barrier Pipe?
A barrier pipe features an additional layer that creates a more effective barrier than plastic alone can provide, protecting water systems and preventing contamination of their contents.
Where are Barrier Pipes Commonly Used?
Barrier pipes are used to transport water supply across land previously used for purposes that may have contaminated the soil with substances that are hazardous to health, including:
- Refineries and chemical processing plants
- Fuel stations, forecourts and vehicle storage or repair facilities
- Manufacturing and processing
- Landfill, scrap yards and hazardous waste treatment sites
- Agriculture and horticulture
Barrier pipes are also used inside buildings for water supply, central heating and underfloor heating, where they prevent oxygen and other gases from entering the pipe and causing corrosion and contamination. This extends the life of the system and protects against leakages.
What are the Benefits of Barrier Pipes?
Barrier pipes offer several important benefits for underground water supply systems and building service installations, including:
- Protects water supply from contamination
- Safe routing of potable water through contaminated ground
- Reduced risk of corrosion and oxygen ingress
- Long-lasting and durable performance
- Compliance with water industry standards
What Materials are Used in Barrier Pipes?
Barrier pipes are typically manufactured using durable polyethylene materials such as MDPE (Medium-Density Polyethylene) and HDPE (High-Density Polyethylene). These materials are widely used within water supply systems due to their strength, flexibility and resistance to corrosion.
What Regulations do Barrier Pipes Comply With?
Barrier pipes are manufactured to meet strict industry standards and water safety requirements for potable water applications. These include the Water Supply (Water Fittings) Regulations 1999, which indicate that every water fitting shall be of an appropriate quality and standard.
What Fittings are Needed to Connect With Barrier Pipes?
Common fittings used with barrier pipes include flexible adaptors, connectors and transition fittings for connecting barrier pipes to standard MDPE water supply systems.
