Septage Receiving Station Procedures

The plant treats hauled septic tank, holding tank and industrial wastes. These wastes discharge to the City system at the Septage Receiving Station.

Components
The station consists of a:
  • 2 discharge stations
  • Computer system
  • Control gates
  • Printer
  • Scale
Weighing Trucks
Trucks are tared (weighed empty) when they register. The weight is entered into the computer and the truck is assigned a key card. That key card identifies the truck, company and tare weight to the computer.

Scale Area
The scale area consists of the scale, a key card reader, an entry keypad/display and a set of lights. To start the process, the truck pulls up to the scale.

Lighted Posts
On the driver's side of the cab are located two posts. The furthest post has red and green lights.
The green light signals the driver that the scale is ready for use. If the light is red, there are operational problems or the scale is in use.

Driving Through the Posts
  1. When green, the driver pulls up to the post in front of the light to the card reader and the keypad/display.
  2. He passes the key card in front of the reader, an audible signal is given to show that the card has been read and the light changes to red.
  3. He then answers a series of questions through the keypad.
  4. The information is fed into the computer and the display alerts him that the data has been accepted and that one of the gates is opening.
  5. As he pulls off of the scale the light changes back to green.
  6. The driver passes through the open gate.
  7. The gate closes automatically
Receiving Building
The driver then proceeds to the receiving building to pick up the computer-generated manifest and a sample cup. The manifest consists of a 3-part form containing the following:
  • Preprinted label with sample number
  • Truck license plate number
  • Hauling company
  • Material type (holding tank, septic, industrial, etc.)
  • Origin (industrial wastes)
  • Sample number
  • Date
  • Time
  • Gross weight
  • Tare weight
  • Net weight
  • Gallons
Gallon Amount & Identification
The gallons are calculated by the computer from the net weight of the waste. The hauler must identify the source of the waste, the address from which the waste originated and the approximate volume.

Discharge Process

  1. Next, the driver connects the hose and begins to discharge.
  2. Midway through discharge he dips a sample from the port and pours it into the cup on which he has placed the preprinted label.
  3. He deposits the cup and the top copy of the manifest into the Receiving Building and disconnects.
  4. The driver empties the hose and washes the area with the flushing water provided.
Charges
Haulers are billed monthly for the wastes that are treated at the plant. The rates are based upon the strength of the waste.
