Under a Creek and through the Woods… and a Golf Course, Dog Park, Baseball Fields… and Trail System

The Trinity River Authority of Texas (TRA) Segment 09BC-1 project is located within TRA’s Central Regional Wastewater System (CRWS). The CRWS service area is the largest within TRA, serving 21 customers by collecting and conveying wastewater flow through over 200 mi (322 km) of pipelines to its treatment plant. The Segment 09BC-1 project includes the replacement of five miles (8 km) of 30- to 54-in. (762- to 1,372-mm) unlined reinforced concrete pipe (RCP) originally constructed in 1984. The design and construction of the replacement pipeline were completed in three phases and involved extensive coordination with recreational properties, including a golf course owned by an international airport and a city park system with baseball fields, a dog park, and trail system. The construction of each phase highlighted certain challenges, such as maintaining project schedule for easements with time constraints, material waste due to unlocated utilities, and review of construction submittals for newly approved manufacturers.
