## Abstract

A wet well design that utilizes recycled material in sectional components to construct wet wells on site is disclosed. Traditional wet well components are made of pre-cast concrete. Green Recycled Material Component Wet Well components are constructed using recycled plastic, recycled steel and recycled Styrofoam. The method described herein for constructing the components and assembling the wet well on site addresses several logistical problems associated with the pre-cast concrete design including reducing project start to completion time, delivery costs, large crane rental costs and power line relocation costs. This design also enables construction of oblong wet wells in medians and other restricted areas as components can be straight or curved sections. Finally, this design eliminates the shifting of traditional cement well components due to uplift from underground water pressure through the use of a new anchoring system. Shifting can result in groundwater intrusion into the well.

## Claims

### Claim 1

Green wastewater pump station circular and oblong wet wells constructed by stacking 2, 3, 4 and 5 modular circular cylinder and straight sections for required well depths of 12′, 18′, 24′ and 30′ respectively and having a mechanical anchoring system; said modular cylinder and straight sections constructed from recycled plastic, recycled Styrofoam and recycled steel scraps in the form of welded wire mesh forming the walls of the wet well and by wet well top and bottom slabs enclosing the modular cylinder wet well walls; said circular and straight sections comprising identical top and bottom frames made of recycled plastic with an inner diameter equal to the desired wet well diameter, vertical members constructed from recycled PVC materials, Styrofoam space refill that fills the space between the vertical members, connecting angles used to connect said vertical members to said top and bottom frames and module stacking connecting bolts that connect said top module frames to vertically stacked bottom module frames; said vertical members having layers of wire mesh reinforcement attached by staples to vertical members' inner and outer surfaces; said inner vertical member surfaces having stucco, stainless steel or galvanized sheet metal coverings and said outside surfaces to be covered by stucco; said mechanical anchoring system consisting of top modular cylinder helical ground anchors and wet well bottom slab helical ground anchors having a minimum 40,000 lb. axial compression load capacity and each comprised of a seamless steel pipe six feet in length and three inches in diameter with two low pitch helical steel cutting blades and being threaded at the top end for attachment to a second seamless steel pipe six feet in length and three inches in diameter threaded at the bottom connecting end and having an eye at the top of it's end; said anchoring system helical steel cutting blades comprising a bottom blade cutting diameter of 8 inches and a top blade cutting diameter of 10 inches and installed with a minimum of 3 top modular cylinder anchors per top modular cylinder installed at a depth of 6 ft. below the top of the well surface and at 120 degrees off each other and 3 bottom slab anchors per modular cylinder attached to the wet well bottom slab at 120 degrees off each other and at 60 degrees in respect to the top modular cylinder anchors.

### Claim 2 (depends on 1)

Circular and straight sections recited in claim 1 having a length of 38 inches on the inner side and vertical members, said vertical members connecting the top and bottom frames and having dimensions where the width is 2 inches, the depth is 4 inches and the height of each vertical member is 68.5 inches,

### Claim 3 (depends on 1)

Vertical members recited in claim 1 wherein the vertical members are placed in a 4 inch wide by ½ inch deep groove cut into the top and bottom frames recited in claim 1 and installed at 18.85 inches center to center of the inner circle of the frames.

### Claim 4 (depends on 1)

Inner and outer surface reinforcing layers of wire mesh recited in claim 1 constructed from cold worked welded wire mesh with yield strength of 70,000 psi to 80,000 psi applied to the vertical members by staples or other suitable hardware.

### Claim 5 (depends on 1)

Space refill recited in claim 1 constructed from high density recycled Styrofoam having dimensions of 18 inches wide by 4 inches deep by 68 inches high and a curvature matching with 4 inch width by 0.5 inch groove for the top and bottom frames.

### Claim 6 (depends on 1)

Connecting Angles recited in claim 1 that are galvanized having dimensions of 2.5 inches by 2.5 inches by 0.1875 inches and a length of 3.75 inches with the necessary holes to attach the top and bottom frames to the vertical members.
