Timp-Nebo Conservation District

Request for Proposals: Centrifugal Separator for Dairy Manure near Elberta, Utah

Introduction

The Timp-Nebo Conservation District is requesting proposals for contractual work in the design, implementation and installation of a centrifugal separator for dairy manure. Project completion date is July 2026.

Please submit by email a proposal to Daniel Gunnell and Katie Ottmann by 5:00 pm, April

17th, 2026.

Daniel Gunnell, Resource Coordinator

(435) 749-0853 drgunnell@utah.gov and katieottmann@utah.gov

Proposals are limited to 10 pages; resumes and references are not counted toward the page limit and may be included in an appendix. A certain level of technical expertise is required to design and install a centrifugal separator. Potential contractors should have a high level of expertise and understanding about implementing centrifuges on dairy operations and the associated manufactures requirements for installation. The process also requires working with an agricultural producer and government agencies.

Project Overview

The Timp-Nebo Conservation District is working with a local landowner, as well as the Utah

Division of Water Quality, and the Utah Department of Agriculture and Food for the installation of a centrifugal separator.

The Timp-Nebo Conservation District is looking for a contractor who will design and install a centrifuge for use on a dairy operation. The dairy is currently implementing a sand lane to separate sand bedding from the raw dairy manure waste stream. After the sand is removed, the raw waste is separated into solids and liquids through a gravity screen separator and screw press. After separation, solids are sent to an on-site composting facility and liquids are sent to liquid waste storage facilities.

The dairy is looking to add a centrifuge after the solid/liquid separation step to further remove remaining solids and impurities (currently approx. 4-9% solids) from the liquid waste stream prior to the liquids being sent to the liquid holding facilities. The dairy would like the centrifuge to remove enough solids and other impurities that the treated liquid would be able to be distributed around the operation through center-pivot irrigation systems. Liquids coming out of the centrifuge should be 2% solids or less.

This bid must include all design and engineering services, including final approval and signature by a Utah Professional Engineer, the centrifuge, and all necessary components for the system to be fully operational, including (but not limited to) plumbing, supply lines, pumps, electrical work or upgrades, etc.

For any operational or design-related questions related to this project, please contact the dairy owner/operator Jason Bateman at jasonjbateman@gmail.com by April 15th, 2026 at

5:00pm.

Project Specifications

The dairy currently milks 9,500 dairy cows per day, and generates 400 gallons of liquid waste per minute, 365 days a year. The proposed system must be able to handle this rate of waste generation at a minimum.

The location of the liquid storage facilities, inlet box, sand lane, and solid/liquid gravity separator are shown on the following map. The gravity separator is already situated in the west half of the existing building. The proposed centrifuge site is located in the east half of the building. The system must be able to fit within the existing building at the centrifuge site location. Interior dimensions of the building that the centrifuge will need to fit in are:

Length: 25 ft

Width: 60 ft

Height: 14 ft

The bid will need to include the following items at a minimum, as well as all necessary components for the system to be fully operational, including (but not limited to) plumbing, supply lines, pumps, electrical work or upgrades, etc:

● Design plan

● Centrifuge

○ 200-400 gpm feed capacity

○ 165 HP total installed power

○ No larger than 6 m x 2 m x 2 m (L x W x H)

● 11.8 inch minimum wet well pump

● 25 HP motor, 1800 rpm

● 8 inch flush pump for 14 foot pit

● 30 HP frame motor

● Pulleys, belts for all motors

● 5 HP air compressor

● Powder coated stand

● Oil/air lube system

● Flow meter

● All electrical panels, wiring, and upgrades

● All necessary supply lines (approx 3,500 feet)

● Any other components necessary for the system to be fully operational
