Samford Valley Wastewater Treatment System Project

We recently had a client who was looking to sell their home but could not get a final home inspection. We were contracted to design and install a suitable wastewater system for their Samford Valley property. 

Our team first assessed the area, completing a site and soil check and a site and soil assessment before designing the wastewater system.

  • Reason for application - no final inspection

Water supply and treatment facility

  • Water supply - reticulated
  • Treatment plant and water quality - Bioseptic secondary effluent
  • Capacity - 6000L
  • Disposal method - heavy droplet spray irrigation

Design calculations

  • Hydraulic load (person/day) - 120
  • Equivalent persons - 6
  • Design flow Q (litres/day) - 720
  • Design sizing calculations - 720 / 3.5 = disposal area 206m2

The existing septic system was retained and our team designed an additional wastewater treatment system to comply with Queensland plumbing and wastewater code, plumbing and drainage regulation as well as the relevant environmental act and regulations.

After we completed the design plans, submitted them to the council and installed their wastewater system, our clients received the final ok to sell their homes.
