Our soil testing, CAD site plans and NorBE-compliant reports meet AS/NZS 1547, WaterNSW and local-council requirements, giving you a clear, cost-effective wastewater solution that speeds up development approval.
The golf course was given unlimited access to secondary treated wastewater, but needed to make sure that stored wastewater, at a prime location within the golf course next to urban development.
This Equestrian Centre with a residential dwelling and amenities for workers had been utilising a septic tank and trench, the system had failed and upgrade was needed.
This required an on-site wastewater system incorporating a system design.
With limited soil depth and available land, this project needed an Aerated Water Treatment System and 4 sand mounds.
