Septage Receiving Station Procedures

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


The station consists of:

  • 2 truck discharge lanes
  • Scale
  • Control gates
  • Computer system
  • Printer

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, and an entry keypad/display. To start the process, the truck pulls up to the scale.

Starting a Transaction

  1. The driver pulls up to the kiosk on the scale.
  2. He passes the key card in front of the card reader, and an audible signal is given to show that the card has been read.
  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 processed.
  5. The display directs the driver to pull forward, and one of the gates opens.
  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 2-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. The driver must sign the manifest. In cases where the scale or computer system are down, the driver must fill out a manual manifest and may be billed for a full load.

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.


Haulers are billed monthly for the wastes that are treated at the plant. The rates are based upon the strength of the waste.
