Prefabricated Grinder Vaults


Prefabricated Grinder Vaults handle the most difficult water conditions for pump and lift stations. This includes wastewater with a high concentration of solids or blow down water containing mineral contents. Romtec Utilities can design prefabricated grinder vaults with any brand or grinder design that will meet specific project goals complete with all product documentation and drawings. We completely preinstall all the fittings, piping, grinder units, and any additional components so that your grinder vault is delivered onsite ready for installation.
