Demand for 1,000-gallon septic tanks was greater than Infiltrator Water Technologies could supply. The company’s solution was developing the CM-1060, a compression-molded septic tank manufactured from recycled polypropylene.

“Infiltrator developed the new tank based on the need to increase production capacity,” says Josephine Alfiero, content marketing coordinator for Infiltrator. “Compression molding is a new manufacturing process to Infiltrator. This process allows us to greatly increase production rates and overall volume.”

According to Infiltrator, compression molding provides an improvement in thermoplastic septic tank design, offering long-term strength and watertightness. 

The tanks design makes it relevant to many water storage applications. “The Infiltrator CM-1060 is suitable for use as a septic tank, pump/trash tank or rainwater storage/harvesting tank,” Alfiero says. “It can be installed as a single tank or in serial tank configurations.” 

Along with versatile use, Infiltrator made sure the design was built to last. Each CM-1060 has reinforced structural ribbing and fiberglass bulkheads, along with two, 24-inch access ports structurally reinforced to help eliminate distortion during installation and pump-outs. The tanks can be pumped dry during pumpouts and no special water-filling requirements are needed. 

The CM-1060 has a total capacity of 1,309 gallons and a working capacity of 1,111 gallons. The dimensions are approximately 62 inches wide by 134 inches long and 54.5 inches tall, and each tank weighs roughly 331 pounds. The tank can be installed with 6 to 48 inches of cover, and heavy-duty green lids interconnect with EZsnap risers and pipe riser solutions. The plastic tanks contain inboard lifting lugs for delivery and handling. The tanks have a two-piece design for shipping and storing efficiencies.

“We spent years developing the process, and we’re pleased with the result and features it will bring to our customers,” says Roy Moore, executive vice president of Infiltrator Water Technologies. “Most importantly, the addition of the CM-1060 represents significant increased tank production capacity to support customer demand.”

Though the product is fairly new, Alfiero says the debut was well received by pumpers and installers. “Those who viewed the tank at the 2022 WWETT Show shared positive comments about the rounded ends of the tank, thinking it would translate into more structure.” 800-221-4436; www.infiltratorwater.com
