CPVC Saves Installation Time For Wastewater Treatment Plants

Every year, wastewater treatment plants across the U.S. treat an estimated 61 cubic kilometers of wastewater – roughly the same volume of water that flows over Niagara Falls in 12 months. The wastewater treatment process requires large vessels and piping systems to handle the polluted water and highly corrosive and caustic chemicals.

Metal piping is seldom an option for wastewater treatment plants because of the highly corrosive environment. CPVC piping has proven a practical choice based on its excellent hydraulic capabilities, corrosion resistance, mechanical strength, and lower life-cycle costs.

CPVC piping also requires significantly less time for installation, which is essential whether the plant is new, expanding, or replacing an existing piping system. The cost savings can be substantial since installation time and related expenses can account for more than half of a piping system’s total price.

CPVC Systems Cost Savings ComparisonLess Labor and Equipment

Corzan CPVC’s comparably low installation cost reflects the fact that its significantly faster and easier to install than traditional metal systems. CPVC weighs 1/8th as much as comparably sized steel piping. A 6” schedule 80 Corzan pipe weighing about 6 lbs per foot compared to 25-29 pounds per square foot for the same size steel piping. The weight difference translates into fewer workers required to handle, install, and secure the CPVC piping. The system is also easier to install in close quarters, with no need for heavy equipment to lift the piping material into place.

Simple Two-Step Solvent Cement Installation Process

CPVC piping is fused using a straightforward, two-step solvent cement process. Solvent cementing requires about half the time to join pipe and fittings compared to welding. Solvent cement chemically fuses the CPVC pipe to the fitting for a highly reliable joint that becomes the strongest part of the entire piping system. These joints are able to withstand the harsh chemicals, high temperatures and pressures present in wastewater treatment plants. Any trained mechanical contractor or plant maintenance engineer can change, repair, or modify a CPVC piping system without specialized equipment. Proper training is essential however, as incorrectly applied solvent cement or cement used in the wrong application can cause joints to fail. Training is available through your local RHFS Service Center.

Versatility and Performance

Sewage, industrial, agricultural and other types of wastewater treatment plants depend on CPVC piping in applications around the globe. CPVC piping can be used virtually anywhere piping is employed to transport fluid or another medium, as illustrated above.

Corzan CPVC piping systems save installation time and offer many performance and maintenance advantages. They are also durable and reliable over the long term. Corzan piping is backed by a 60-year history of success across a wide range of industries worldwide.
