The Franklin Miller grinder manholes include a powerful TASKMASTER® grinder, a prefabricated FRP manhole enclosure, controls and many optional features. These units are custom-designed for your site conditions. This watertight unit is corrosion-resistant and engineered for the extreme conditions of sanitary and industrial flow streams, making it a durable, long-lasting choice. The complete manhole system can quickly be up and running, protecting downstream equipment and providing savings for the district.


Plug and Play

The complete packaged FRP manhole makes installation a snap – simply dig a hole, drop it in and hook it up. The system is constructed specifically for a TASKMASTER grinder which is installed in a built-in channel. With available depths from 5 – 35 feet and diameters in 48”, 60” and 72”, the manhole is fully customizable to your site. The manhole’s lightweight design results in much lower installation and material handling cost as well as minimizing of the plant downtime, with typical installation at a prepared site being between 3 – 4 hours. The units are provided with an access ladder, a choice of hatches and optional grinder siderails.
