Remote 200 Man Work Camp Sewage Treatment Plant

Case Study

Customer: Origin Energy

Location: Near Euthulla, QLD

Specifications & Features:

Water Use:
Dowdens Pumping and Water Treatment were contracted by Origin Energy to design, manufacture, supply, install and commission a Rotating Biological Contactor (RBC) and Ultrafiltration (UF) Sewage Treatment Plant (STP) for a 200 man work camp located at their Spring Gully site - Euthulla (near Roma).

The treated effluent is discharged to an onsite Pongamia plantation via an irrigation system in accordance with criteria from the Class A recycled water guidelines.

STP Water Quality Output:
Class A recycled water

Daily Treated Water Production: 60kL


Plant Description:

Incoming raw sewage is deposited in primary holding/settling tanks where primary settlement and anaerobic digestion occurs.

The retention capacity in the holding tanks ensured proper settling of bio-solids and anaerobic digestion occurred. The settling tank effluent then flows through to the rotating disc stage where aerobic treatment takes place.

Effluent from the rotating disc stage then passes through the clarifier. Treated effluent from the clarifier is then pumped through the UF system to further reduce the suspended solids level to meet final treated effluent quality.

The effluent is then dosed with liquid chlorine enabling effective disinfection prior to use for onsite plantation irrigation.

STP Components:

  • System is capable of treating 60m3/day of raw sewage into to Class A effluent
  • 12.2m3 pump station complete with duty stand-by maceration pumps
  • Emergency 30m3 peak flow storage tank
  • 2x 1.1kW Rotating Disc Rotor Units
  • Electrical Control Panel, Chlorine Disinfection and Filter Room all and housed in refurbished shipping containers with air conditioning and lined panels
  • 4x 47kL treated effluent/wet weather storage tanks with interconnecting pipe work
  • Class 'A' UF Polishing System Components:

    • UF polishing system housed in a refurbished shipping container with air conditioning and lined panels
    • Chlorine dosing system with 200L tank, level sensor and 2x dosing pumps
    • 650L filter backwash tank with level sensor
    • PLC based control panel with HMI Touch Screen
    • Fully automated irrigation system supplying treated water to Pongamia plantation

Oil and Diesel Fuel Pump Set

Case Study

Customer: FK Gardner & Sons Group

Location: Rockhampton, QLD

Specifications & Features:

Dowdens Pumping and Water Treatment have successfully installed and commissioned a specialised oil and diesel fuel pump set for Hastings Deering (Rockhampton) on behalf of the FK Gardner & Sons Group.

Project Requirements: The objective of the project was to transfer large quantities of oil and diesel fuel as quickly and efficiently as possible from an onsite fuel store to the 'Engine Dyno' rooms.

Plant's Critical Requirements:
  • Supply of oil had to be delivered at a minimum of 20L/min per hose reel
  • Diesel fuel was to be transferred from bulk onsite storage tanks to smaller 1000L 'day tanks' - then transferred directly to the 'Engine Dyno' rooms


Key Plant Features:
  • Fuel transfer is triggered via ultra sonic level sensors which tell the pumps to start once a minimum level is reached, once the maximum level is reached pumps automatically switch off
  • Wilden Air Pumps were used to transfer both the oil and diesel fuel to the 'Engine Dyno' rooms
  • 63mm Dura Pipe PLX was used for the diesel lines - this particular poly pipe utilises a durable internal lining to handle diesel fuel
  • The process used for the joining the Dura Pipe PLX was 'Electrofusion'
  • Existing onsite pipes were 63mm Calair Oil Pro Pipe which is used to transport oil to supply the oil reels in the 'Engine Dyno' rooms
  • The process used for the joining of the Calair Oil Pro Pipe was 'Socket Fusion'
