Addendum No. 1

September 11, 2026 clarification/additional information:

1) Regarding the "Muffin Monster" installation, points of clarification:

1. The well is intended to be a fiberglass well to replace the existing concrete M.H.

at Station 8+27 (approx) per the attached drawing C905 provided by JWC Environmental.

SEE ATTACHED REFERENCE MATERIALS.

Muffin Monster® Manhole

Drop-in ready manhole with integrated grinder for pump protection anywhere The Muffin Monster Manhole makes it easier to install a grinder into sewage systems. The fiberglass reinforced plastic (FRP) manhole can accommodate the channel mounted 10K, 30K and 40K series Muffin Monsters.

Users can also select a Channel Monster® CMD single drum grinder for dealing with higher flow levels. With this flexibility, the Muffin Monster Manhole can now treat difficult solids and eliminate costly pump breakdowns for flows up to 2,060 GPM. Designed and built off site, the Muffin Monster Manhole makes for a quick, clean installation. On site, a hole and a concrete slab to put the FRP manhole onto are all that is required before you are ready to install the chamber, connect the power and the sewage line, and begin operation.

Using a 48” diameter standard barrel and prefabricated channel design to suit the relevant grinder model, the height, pipe size and choice of traffic or hatch top cover makes the Muffin Monster Manhole a cost-effective and customizable solution for ease of installation in gravity sewage systems.

Traffic grade opening with 30K grinder and integral bypass weir (optional)

40K grinder with single lifting point and OSHA compliant ladder

Hatch access for above ground installation

Dual-shafted Muffin Monster Grinder

• Low-speed, high-torque grinder handles rags, rocks, wood, clothing, plastics and other debris that cause problems in wastewater systems

• Adding the Channel Monster CMD to the Muffin Monster Manhole processes higher flows while minimizing upstream level increases for shallow networks, or when upstream levels are critical

• JWC-exclusive immersible motor ensures continuous operation even in flood conditions

Manhole

diameter varies with grinder model.

• Hatch choice: Lid style for above ground installation and H-20 rated traffic style for below grade installation

• Two standard channel trough configurations to suit either 10K / 30K grinders or 40K / CMD grinders

• Integral guide slots eliminate the cost of an additional grinder frame

• Floor recess for grinder maximizes flow capacity, minimizes upstream head and seats grinder correctly

maintenance access

Installation and Maintenance

• Less than 8’ deep, guiderails are optional. At greater than 8’ deep, guiderails are mandatory.

• Minimal maintenance with semi-annual inspection

Optional

• 60” and 72” manhole barrel diameters available as special orders to meet specification

• Single point lifting frame and haul chain available for all models
