Graf HD Septic Holding Tanks

Web Id: 1601

With high stability and strength, these German-engineered Carat S tanks by GRAF exceed industry standards. You’ll love them for their versatility, ease of installation and use, and low shipping and operating costs. Use the Carat S as a septic tank, pump chamber, or wastewater treatment system. These belowground Carat S tanks are also ideal for rainwater harvesting and stormwater retention/detention. The groundwater stable tanks feature long-lasting water-tightness, thanks to a circumferential profile gasket, and they are suitable for vehicle loading.

The GRAF Carat S tank range is produced using a method that is as yet unique for tanks of this size. The injection compression process gives the products an incomparable stability – all Carat S underground tanks are suitable for vehicle loading and can be installed in groundwater up to the middle of the tanks. Additionally, the new method guarantees that the components will fit; a result that cannot be achieved with conventional production methods.
