When you enter the water treatment plant, there is some mixed mesquite hackberry woods on the left (south) side of the road. Scan these woods for woodland species.

Follow the road until it makes a 90° left turn. Do not enter the interior fenced area of the water treatment plant.

Instead go on the left side of the fence, parking anywhere in that area. A good place to park would be close to the first dividing crossover berm.

One can walk out to and then around the three north-south linear ponds.

Hargesheimer WTP stands for Water Treatment Plant—which is another term for the city's sewage treatment or wastewater treatment.
