Samford Valley Wastewater Treatment System Project
Published: August 03, 2020 Last Updated: October 12, 2020
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 firstly assessed the area, completing a site and soil check and a site and soil assessment before designing the wastewater system.


Details of the property:
- Allotment Area - 1.5 hectares
- Slope - 10%
- Dwelling - 4 bedrooms
- Weather - fine
- Existing waste disposal - Bio septic HSTP
- Reason for application - no final inspection
- Soil - loam / clay loam
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 watewater code, plumbing and drainage regulation as well as the relevant environmental act and regulations.



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