As of February 24, 2017 the project is more than 98% complete and remains on schedule to be in service by the end of March 2017.

We are completing inspections and testing of the pipeline, going above and beyond where possible all state and federal requirements.

Prior to being put in service, testing includes checking coating integrity, x-raying 100% of the welds (which is well above the 10% required by federal regulation), internally inspecting the entire length of the line by using an in-line inspection tool known as a caliper pig, and hydrostatically testing the pipeline to 125% of the maximum operating pressure.

The hydrostatic (water) testing is always done after the pipeline is buried in order to ensure the integrity of test results (i.e., the pipe in its final conditions) and for safety. We use fresh water with no additives to hydrostatically test the pipeline. We will use approximately 6.4 million gallons of water acquired from a private water well in Pecos County to test 26 segments. Each segment is individually permitted and will use the same water in order to minimize water needed. The total amount of water needed to hydrotest the entire Trans-Pecos Pipeline will not exceed the approximate 6.4 million gallons of which 1.2 million gallons will be used for the first two segments of the pipelines, and the remaining 5.2 million gallons will be used for the remaining 24 segments.

Once testing is complete, the water is then tested and filtered prior to proper discharge in strict compliance with state regulations. Our application for these permits explains that the 1.2 million gallons will be discharged at the north end of the pipeline and the remainder will be reused and discharged near the south end of the pipeline in Presidio County.

Trans-Pecos Pipeline Overview

The Trans-Pecos Pipeline is a Texas intrastate pipeline designed to transport 1.4 billion cubic feet per day of clean-burning natural gas as part of an agreement with Comisión Federal de Electricidad, Mexico’s federal electricity commission.

Texas-based Energy Transfer Partners is responsible for constructing and operating the 148-mile, 42-inch diameter pipeline which will originate at the Waha Hub outside Fort Stockton, Texas in northern Pecos County. The pipeline will include delivery locations for local towns and utilities in Central West Texas and terminate custody at the U.S.-Mexico boundary near Presidio, Texas.

The Trans-Pecos pipeline will provide new market outlets for domestically produced clean-burning natural gas, thereby encouraging continued production in the U.S. energy sector. Construction is anticipated to start by Q1 2016 and the project is expected to be in service by the end of Q1 2017.

Approximate Mileage Per County:
Pecos: 47 miles      Brewster: 34 miles      Presidio: 67 miles


The Trans-Pecos Pipeline has begun surveying the area as part of its process to identify the desired route that creates safe and reliable transmission infrastructure. To accomplish this, we are performing civil, environmental and endangered species surveys.

As currently planned, the 148-mile pipeline will originate at the Waha Hub outside of Fort Stockton in northern Pecos County where there will be one compressor station providing all necessary horsepower for the entire route. The pipeline will include delivery locations with local towns and utilities in Central West Texas and terminate custody at the U.S.-Mexico boundary near Presidio, Texas.
