REHAU, a global supplier of polymer-based solutions and leading North American PEXa manufacturing company, is offering two additional cross-linked polyethylene PEXa pipes in its municipal piping program. In addition to MUNICIPEX water service line, the expanded product range now includes MUNICIPEX pre-insulated for cold-weather applications and MUNICIPEX force main for wastewater applications. From new construction to replacements and repairs, the MUNICIPEX line offers ease of installation, longevity and resiliency for municipal projects.

“With more than 1 billion feet of REHAU PEXa pipe installed worldwide and many North American water service projects, municipalities have reason to trust MUNICIPEX to safely and efficiently transport potable water,” says Dale Gentry, REHAU MUNICIPEX national account manager. “Now, with our expanded line including pre-insulated and force main, we are building on this proven performance with cold-weather and wastewater solutions. These products offer the efficient installation and longevity that municipalities have come to expect from MUNICIPEX water service line.”

MUNICIPEX Water Service Line

MUNICIPEX water service line delivers potable water from the water main to any residential or commercial structure. This durable cross-linked polyethylene (PEXa) pipe is a clean, easy and cost-effective alternative to copper, HDPE and other materials. It is available in 3/4- to 2-inch diameters and coils up to 1,000 feet. MUNICIPEX water service line is backed by a 25-year limited warranty and has been trusted by municipalities for more than 20 years. It is certified to AWWA C904, CSA B137.5 and ASTM F876.

MUNICIPEX Pre-Insulated

Specifically for water distribution in colder climates, MUNICIPEX pre-insulated provides an extra level of protection from freezing, particularly useful when laying pipe below the frost line is not possible. A MUNICIPEX carrier pipe is surrounded by a solid layer of CFC-free polyurethane foam insulation and a corrugated LDPE outer casing that provides superior durability. Next to the carrier pipe is a conduit through which heat trace wires can be run. MUNICIPEX pre-insulated is available in 1- and 2-inch diameters and coils up to 300 feet. It is certified to AWWA C904, CSA B137.5 and ASTM F876 and is backed by a 25-year limited warranty.


MUNICIPEX force main is used in publicly owned treatment works systems for conveying wastewater under pressure from the discharge side of a pump or pneumatic ejector to a discharge point. The pipe is color coded with a green coating that helps installers easily identify wastewater applications. It is available in 1 1/4- to 2-inch diameters and coils up to 1,000 feet. MUNICIPEX force main is certified to AWWA C904, CSA B137.5 and ASTM F876 and is backed by a five-year limited warranty.

Properties of MUNICIPEX

The advantages of MUNICIPEX begin immediately upon installation. Designed and engineered to make installing the pipes easy, MUNICIPEX is supplied in long, flexible coils that help reduce the number of couplings, minimize waste and speed up the installation process. Unlike other competitive plastic solutions, MUNICIPEX is easier to bend and resists kinking. Beyond its natural properties that promote efficient installation, there are no special tools required to make connections, ultimately simplifying the installation process. In water service applications, MUNICIPEX is up to 70 percent lighter than copper, making it easier and safer to carry and uncoil. 

Once installed, MUNICIPEX is highly engineered to perform in the toughest environments and will last for years. Unlike other municipal service lines that need to be replaced frequently, MUNICIPEX is resistant to corrosion and mineral buildup, chlorine and chemicals, and freezing, as well as impact and abrasion. The highly crosslinked polyethylene (PEXa) structure of MUNICIPEX pipe increases its ability to withstand harsh conditions without compromising performance. Compatible with native backfill and resistant to UV, slow crack growth and abrasions, MUNICIPEX surpasses alternatives regarding resilience and environmental sustainability.
