About JWC Environmental Inc.
- Monster Industrial marine sewage system grinders are used to keep your onboard wastewater system flowing freely. They grind up all kinds of debris into small particles minimizing solids backups that require clean out. This not only reduces maintenance costs, but also protects the health of the crew. 1-HYDRO & 3-HYDRO grinders will protect pumps from rags, hygiene products and other items that should not be flushed in the first place.
