We offer Wastewater (sewerage/septage/foul water/black water) and grey water disposal designs. For rural properties not connected to public sewer systems, we can advise what level of treatment is required i.e. Primary treatment, Advanced Primary treatment, or Secondary treatment. We can then design septic tanks or advanced treatment systems as appropriate for the site and proposed development, with effluent disposal fields operating on gravity or pumped as site topography dictates. When there is a public connection available but councils also require engineering design to connect to these services, or for development of subdivisions, we are also able to provide infrastructure design services.
