In 2007, Old North Utility Services, Inc. (ONUS) was awarded a 50-year contract to operate, maintain, repair, upgrade, and improve the water and wastewater utility systems at Fort Bragg, Pope Army Airfield, Simmons Army Airfield, and Camp Mackall. Fort Bragg is the home of the Army's airborne (including the famed 82nd Airborne Division) and special operations forces, while Pope Army Airfield is the home of the 43rd Airlift Group and the 18th Air Support Operations Group. Fort Bragg is located in the Sandhills Region of the south-central portion of North Carolina - ten miles northwest of downtown Fayetteville. The Fort Bragg complex, including Pope Army Airfield and Camp Mackall, encompasses over 160,000 acres and extends across portions of four North Carolina counties.
In an effort to provide reliable wastewater collection service to the military complex, the force main from Lift Station 1 needed to be reinforced and upsized to 18-inch diameter. ONUS project manager Brannon Richards noted: "In my previous position as a consultant, I designed an HDD water crossing using Fusible PVC® pipe, so when it was determined that certain sensitive areas along the Lift Station 1 force main alignment would require trenchless installation, I strongly encouraged our consultant to consider both types of butt fused plastic pipe. In the marketplace, the Fusible PVC® pipe won out, saving ONUS and Fort Bragg construction dollars."
|Pipeline Details and Project Summary|
|Project:||Lift Station 1 Force Main|
|Location:||Fort Bragg, NC|
|Owner/Operator:||Old North Utility Services|
|Consultant:||URS of North Carolina|
|General Contractor:||State Utility Contractors|
|Subcontractor:||Hi-Tech Construction Company|
|Description:||Install 11,000 LF of 18 inch force main, including installation of approximately 1,300 LF of 18 inch force main via horizontal directional drill (HDD)|
Hi-Tech Construction Company, Inc. of Myrtle Beach, SC bid a turnkey package of horizontal directional drilling (HDD) to prime contractor, State Utility Contractors of Monroe, NC. When State was awarded the contract, Hi-Tech immediately began preparations for what would be winter work on Ft Bragg. Hi-Tech's favorable Fusible PVC® pipe bid was based on a combination of material and labor savings over the HDPE pipe alternate option. Both products needed to be at least 17.5-inch inside diameter and rated at 200 psi operating pressure. For Fusible PVC® pipe, that meant 18-inch DIPS DR21, but for HDPE, 24-inch DR9 was required. Said project manager Jim Thomas: "Although this was not our first experience with Underground Solutions' fused PVC products, the size and length of these drill shots made this a critical application. We took particular care to maintain entry pits according to information provided by Underground Solutions and supported their cold weather fusion. All said and done, this project went very smoothly for us."
