This 5.4 million gallon tank was built at 157’ diameter by 40’ tall, with a knuckle roof, and overlooks the new housing development of Audie Murphy, but can be seen from surrounding communities to the west. One of the unique things about this tank is that, when you’re looking for it from the east end of town, it is painted to blend in with the hillside that it was built into, so you really have to scan to find it. In order to make room for this site footprint, and to set the tank at the proper elevation, over 25,000 cubic yards of dirt /rock had to be blasted and removed. As a customer preference the reservoir was designed with a modified structure to support the large roof platform as the additional weight required rafters, poles and a girder to be increased in thickness. Along with their preferred platform design, this customer is extremely particular about operator safety, so they design all of their tanks to have 360 degree handrail, roof tie off cables, and fall resistant grading shields, located on all roof access hatches. As you can see in the picture, the tank is fitted with 5 custom aluminum roof vents, which really standout against the dark color of the tank and hillside.
