Projects
Cunningham Containment Wells
The Cunningham Containment Wells Project broke ground on September 14, 2012 in Cunningham, Kansas. This project required the abilities and experiences of our team at Serco to complete a total of two withdraw wells, three injection wells and the installation of approximately 18,700 linear feet of 4-inch high density polyethylene (HDPE) pipe to interconnect all five wells. The construction of the containment withdrawal wells involved installing an actuated valve, a meter, an isolation valve and associated piping. All installed piping was pressure tested according to the client's engineering standards. Helical piers were installed to support two prefabricated instrument buildings. Installation of electrical work for the two withdraw wells was finished and then a six foot fence was erected around each well site. The two new withdrawal well sites were then graveled.
The construction of the three injection wells involved installing control valves, meters, a holding tank, a seal pot and associated piping, as well as all electrical work. Helical piers were installed to support the building foundations and the holding tank foundations. A six foot security fence was erected around the three injection well sites. The three injection wells were then graveled. Finally, approximately 18,710 feet of new HDPE pipe was installed to interconnect all five well sites. All HDPE pipe was pressure tested according to the client’s engineering standards.
The Cunningham Containment Wells Project was completed in March 2013 with no injuries, on schedule and within budget.

Palmyra Building #2 Automation Project
In March, 2014 we began the Palmyra Building #2 Automation Project, located in Palmyra, Nebraska. During the construction of this project, we expect to run approximately 2820 linear feet of ¼” stainless steel tubing. About 640 linear feet of tubing is required from the engine to the unit control cabinet. Another 2180 linear feet of stainless steel tubing is needed from the engine to the transmitter rack. New electrical conduit and wiring will also be installed from existing PLC’s to three existing engines inside a compressor building. Two cable tray stanchion supports will be fabricated and installed and three existing cable tray stanchions will be modified to support the new electrical conduit. We plan to remove and replace nine 600 pound valves, 3 each 11/2”, 2” and 6”. The valves will be tested and painted. It will be necessary to remove approximately 8 ½” of 20” OD piping in three locations. Our crew expects to install three 20” butterfly valves on three separate 20” air filter lines.
Approximately 72 linear feet of 2” irrigation line, spigots and cap ends will be removed to make necessary room for a new annex building. Then we will build a new 48’ x 24’ annex building foundation. Finally, approximately 490’ of 12” waste water discharge drain pipe will be removed and replaced we will install with approximately 650’ of 6.9” ductile iron pipe and backfill. Our plan is to complete the job with 2500 linear feet of backfill.
This job is currently underway.

Replace Damaged CO₂ Header
Hereford Renewable Energy, LLC
The Hereford Renewable Energy project to replace the damaged CO₂ header above the fermenter #2 was done in two separate phases. The first phase occurred at the end of 2013 and consisted in erecting a temporary 100 foot tall pipe rack to support the existing CO₂ header in order to remove and replace the damaged fermentation tank. Two cranes were used (100 ton and 140 ton) to set up the temporary pipe rack. Once the pipe rack was set in place, the damaged fermentation tank was removed and replaced by others. The second phase consisted in replacing the damaged CO₂ header vent piping and was finished the early part of 2014. Most of the fabrication of the new header vent piping was done in the shop to reduce the amount of field welds and was then delivered to the site ready for installation. The header piping was fabricated using stainless steel which consisted of 16-inch, 20-inch, and 22-inch piping and respective fittings. After the new CO₂ header was installed, the temporary pipe support was removed and dismantled as well as all the scaffolding used for the downcomers of the fermentation tank. The project was completed in March of 2014 with no injuries, on schedule and within budget.
