BACKGROUND
This project is to provide a 48-inch diameter treated water pipeline to convey water from the existing Leonard treated water pipeline in the vicinity of Farm-to-Market Road 981 south to the existing Farmersville delivery point. The alignment selected during the initial phase of design is approximately 11.5 miles long. This scope is a continuation of the project design stage, advancing from 30% Preliminary design to the completion of bid documents and procurement of the project.
PROJECT PURPOSE
• The proposed 48-inch pipeline will provide additional capacity to the East System to meet projected demands through the year 2050.
• This project was identified in Project No. 101-0588-21, the Water Transmission System CIP Update.
• The Opinion of Probable Construction Cost is $65,000,000.
PROJECT COMPONENTS
• This project includes the design of approximately 61,000 linear feet of 48-inch pipeline from a new branch connection on the existing 84-inch Leonard pipeline to a tie-in location near Farmersville Delivery Point No. 1.
• The proposed project alignment crosses numerous streets, highways, and creeks. Most of the proposed alignment would be performed by open cut, with multiple short sections of jack and bore.
• Consultant services include Right-of-Way (ROW) services for right of entry to all parcels and final land acquisition of all parcels.
ADDITIONAL SERVICES
• Final Engineering Design to develop the 100% design set and provide Bid Phase support.
• Special Services as needed to support the design development, including:
o Real Estate Consultant Services
o Environmental / Cultural Resources / Archeological Services
o Geotechnical Services
o Survey Services
o Corrosion Services
o Subsurface utility investigation at potential critical conflict locations
FUNDING
Funding to HDR Engineering, Inc. in the amount of $5,199,428 is to be made available in the Regional Water System Capital Improvement Fund.
