Looped Water System
Briar Chapel, Water Systems
McAdams has assisted Newland Communities with a number of development phases at the Briar Chapel Community in Chatham County. This site is approximately 1,600 acres and was initially permitted in 2004 for nearly 2,400 residential units and continues being developed in a phased approach. McAdams has been involved in Briar Chapel since its initial steps towards entitlement in 1999 and has provided land planning, surveying and civil / site engineering design and permitting for the initial and several subsequent phases of approximately 800+ lots to date.
Design of the initial water system for Briar Chapel involved coordination with Chatham County for connection to the County water system and coordination with Chatham County Fire Chief, Tom Bender, in regards to fire flow requirements. Working with the proposed land plan, McAdams developed the preferred routing to create an efficient and effective water system into and through the Briar Chapel Community in order to create a looped water system that serves as the “spine” from which the various Briar Chapel residential pod networks feed. McAdams’ efforts involved considerable WaterCAD modeling to ensure that Briar Chapel would have sufficient flow and capacity, not only for the phases under construction but also for future phases as build out progressed. These modeling efforts resulted in Briar Chapel water system connection points to existing Chatham County water mains along Highway 15-501, Andrews Store Road and Manns Chapel Road. In addition, McAdams’ modeling efforts also resulted in the developer installing approximately one mile of a larger than required water main (12-inch versus 8-inch) along Andrews Store Road from the end of the existing 8-inch main to the entrance of the Briar Chapel development in order to facilitate future water system improvements that the County may wish to implement by upsizing approximately 1,500 linear feet of existing 8-inch waterline along Andrews Store Road to a 12-inch main to connect to the existing 12-inch main along Highway 15-501.
Briar Chapel is in a primarily rural setting where no wastewater treatment facility existed in the area. McAdams served as the lead for the permitting of a 750,000 gpd on-site reclamation treatment facility and spray irrigation system through NCDENR. McAdams also designed and permitted three pump stations (371 gpm, 673 gpm) and developed the preferred routing for the gravity collection system to the initial pump stations and the force main from the larger pump station to the reclamation facility approximately one mile away.
