Haulers unload grease and septage from 6 a.m. to 6 p.m., but the bays’ lighted canopies are equipped to allow for 24-hour delivery in the future.
Once the driver swipes a Dallas key and enters load type (septage or grease), the unit automatically directs a three-way selection plug valve to select the corresponding pipe position. The driver gets a printed receipt when the delivery is completed.
Haulers used to dump directly to the treatment plant’s headworks through a single hole in the ground. Now discharge bays have three-way plug valves that direct flow to the appropriate screening area.
