Gayle Manufacturing - Commercial Project Case Study

Background

From their origins in Sacramento, California, Gayle Manufacturing expanded quickly from one man machine shop in 1968 into one of the top 5 commercial structural steel manufacturers today. Gayle expanded to Nampa, Idaho in 1997, and in 18 short years, found they needed a new and much larger facility. A location was selected in nearby Caldwell and as part of the planning process, a waste treatment and disposal system was needed for the future workforce.

Design and Construction

In 2015, Mason & Stanfield, Inc. of Nampa, Idaho was hired to handle the civil portion of new Gayle project. Scott Stanfield contacted R.C. Worst & Co. for help on the wastewater permitting and design. Working with South West Health District and the Idaho Department of Environmental Quality, R.C. Worst & Co., was able to work within the time constraints the project presented. Collaboration between the people of Gayle Manufacturing and Mason & Stanfield, R.C. Worst & Co. provided a comprehensive package to include two solid sewage lift stations, a wastewater treatment facility using Orenco’s new AXMAX AdvanTex treatment package as the core component. A septic tank made by Xerxes was selected due to the presence of shallow groundwater at this site, and the design team wanted no issues with the tank leaking into the adjacent water table. Once treated, the disposal field was designed and constructed to handle the daily design flow using a series of four, 6’ wide by 158’ long trenched. Each trench was pressure dosed insuring equal coverage over all the infiltrative surface area. Presenting a hydraulic design challenge, the field is located hundreds of feet from the facility and treatment system. This issue was solved by pumping directly from the discharge tank of the AXMAX system. Two Orenco high head pumps provide the muscle to more the water to the field. Delivered and installed during the week of February 29th, 2015, a member of the R.C. Worst & Co. design team supported a successful installation by Lurre Construction also of Caldwell, Idaho. The Lurre team was top notch and proved to be an excellent construction partner. By the end of that week, one lift station, the tanks and the field was ready for the next phase.

Operation

The Gayle Manufacturing system has is still under construction, but updates to this project will be posted as they happen.

System Design Detail Summary

Project Referral - Written By Scott Stanfield, PE

I am a civil engineer located in Nampa, Idaho. I recently had the pleasure of working with R.C. Worst & Co. on a local industrial project. I worked directly with Allen Worst on the septic treatment system. The project was complex and the site has high groundwater with very high nitrate levels. The project had a rapid schedule. The owner and I reached out to Allen and he responded professionally and quickly. His performance exceeded my expectations. His experience, knowledge, and relationships with the approving agencies (State and local) was refreshing. His work started with assisting us in gaining approval of the Level 1 Study. He was very proactive and quickly moved onto the design stages. He continued working with us throughout our design process. He paid attention to our work on the water system, the drainage system, the onsite well, etc., knowing what we were doing, and thus avoided conflicts between site features not related to his product. He stayed in contact with us almost daily, making sure we had what we needed (and gently reminding me of tasks I needed to complete). I highly recommend R.C. Worst for your treatment needs. Let Allen assist you. Don’t have the attitude that many engineers have toward outside help!! Allen and R.C. Worst has the experience and knowledge and an in-house licensed engineer to make your project a success!!!
