The Firm has conducted numerous wastewater assessments and reports over the last two decades. Clients have included single residential allotments through to large scale residential and commercial developments including factory sites, multi-residential subdivisions and retirement villages and hostels.
Wastewater assessments require a detailed site investigation to be conducted inclusive of soil test work to establish the capacity of a development site to accept wastewater. Consideration is given to the scale of the development, the likely volumes of wastewater generated and the site constraints (eg: soil characteristics, topographic features and site drainage conditions).
Reports are prepared referencing the Environment & Health Protection Guidelines, the AS/NZS Standard 1547:2012 and the local council’s approvals policy for new installations of On-site Management Systems.
On-site wastewater systems can occupy a large area so it is important to factor them in on property developments where reticulated sewage is unavailable.
A range of on-site wastewater management options are available. Each site is different as are owner-opertator expectations. We at Harvest Scientific Services will tailor-design each system to suit accordingly.
