Understanding the Hickory Pipeline

- We are looking at how the Hickory Pipeline works to bring water 62 miles from the Hickory Aquifer, located in the nearby McCulloch county, to the old Water Treatment Plant in San Angelo.

The trip to the Hickory Pipeline begins at the Surface Water Treatment Plant in San Angelo. Then the pipeline travels to the highpoint tank, which holds half-a-million gallons of water, at the Hickory transmission line.

"It's about 50 feet in diameter and about 30 feet tall. Now, this is the high point of the transmission line. This is the line that runs from the Hickory Aquifer to the city of San Angelo," stated Kevin Krueger.

From the highpoint tank, the water travels downhill to the booster pump station at the Hickory Aquifer.

"We are in the booster pump station electrical control room and this is where the computer system and the instrumentation and control comes together," continued Krueger.

The booster pump station is the heart of the Hickory Pipeline. Engineers can remotely control how much water is pumped from the wells, choose which well will be pumped, and the amount of water in the high point tank.
Nine water wells are already operating and six new wells are being drilled.

"The system can be operated from this building at the Hickory Aquifer and it can also be operated at the water treatment plant using the same system," Krueger said.

With the addition of six new wells, a new pump will be added as well.

From the booster pump station, the water will go to the nine exisiting wells. Once the six addional wells are complete, they will connect to booster pump station.

To reach each well, the well's depth will be anywhere from 1,000 to 2,000 feet,  depending on the depth of the well.
