What is the latest on Northeast Interceptor?
Jun 9, 2026: Council approves $95,000 Kimley-Horn amendment for construction-phase services through May 2026. On June 9, 2026 the council approved, 5-0 on the consent agenda, Amendment No. 3 to the Kimley-Horn agreement for $95,000, bringing it to $5,441,800, for a project representative and materials testing from January through May 2026, funded from water and sewer revenue bonds (CIP No. 530042).

How far back does this record of Northeast Interceptor go?
To Feb 23, 2021: Council approves $5,248,300 Kimley-Horn agreement to design the Northeast Interceptor. The storyline has 16 dated events in all. Read the event

Phase 1 of the Northeast Interceptor, about 13 miles of gravity sewer main carrying northeast Amarillo wastewater to the River Road Wastewater Treatment Plant, was built under a $71,266,760.15 contract awarded in October 2023 (later $72,862,527.80) and reached substantial completion in May 2026. Phase 1 also took an Imhoff tank and a lift station out of service; City staff said it would move about 1 million gallons per day off the overloaded collection system that feeds the Hollywood Road plant. The council hired Kimley-Horn to design it in February 2021 ($5,248,300, later amended to $5,441,800) and approved easement and surface-damage agreements with landowners in 2022 and 2023. Two bids were opened on September 14, 2023. On October 24, 2023 the council awarded Phase 1 to S.J. Louis Construction of Texas, with $23,826,635.15 to come from revenue bonds still to be issued. On December 12, 2023 it authorized the New Series 2024 water and sewer revenue bonds ($19,300,000 issued), which the staff memo tied to the interceptor, and in January 2024 approved an AEDC agreement to pay half that debt service. Two change orders brought the contract to its final amount; a June 2026 staff memo reports the substantial completion.

    Council approves $5,248,300 Kimley-Horn agreement to design the Northeast Interceptor

    On February 23, 2021 the council approved, 5-0 on the consent agenda, a $5,248,300 professional engineering services agreement with Kimley-Horn and Associates for the planning, design, procurement and construction phases of the northeast wastewater interceptor line. The agenda description said the line was essential for future growth, including the future expansion of Centerport, and would serve or relieve underserved areas on the east side of the City.[1][2]

      A January 2024 amendment describes the Kimley-Horn agreement as dated February 24, 2021, for design and construction services for about 80,000 linear feet of sanitary sewer mains in Potter County, and says funding for the project was approved in the FY 16/17 through FY 20/21 Community Investment Program.

      The two CIP editions that list the interceptor describe it differently. The FY2020/21 edition calls it "a multi-year pipeline project to help eliminate strain on the wastewater collection system" that would "open up gravity flows on the Northeast side of Amarillo and potentially eliminate the need for future lift stations and the Imhoff tank." The FY2022/23 edition says it "will run from I-40 north to the RR WRF" (River Road Water Reclamation Facility) and "will Move water currently going to HR WRF [Hollywood Road] to RR WRF." [3][4]

      Phase 1 consists of about 13 miles of sanitary sewer pipe and the abandonment of an Imhoff tank and a lift station in the northeast basin. The memo says the lift station being abandoned serves the prison and nearby industrial park and pumps about 1 million gallons per day, which is pumped five more times before reaching the Hollywood Road plant; that previous studies showed this system to be overloaded per TCEQ requirements; and that the interceptor would move that flow by gravity to the River Road plant. It says the interceptor was a high-priority need in the 2012 Wastewater Master Plan and the Northeast Basin Study, and lists added service to the Centerport industrial area, growth and reduced pumping as long-term benefits.
