Onsite Wastewater

GWE Consulting has a history of offering innovative, appropriate and environmentally sustainable solutions for onsite wastewater systems from single lot through to community and subdivision developments. Our team of engineers are able to provide practical, economic solutions from a range of treatment and disposal technologies whilst meeting the community’s environmental, social and cultural needs.

Pre-purchase Inspections and Due Diligence

The purchase of rural and lifestyle property presents a number of risks not present with urban lots, including reliance of on-site treatment and disposal systems for the management of domestic wastewater. GWE offer a comprehensive assessment of existing on-site wastewater systems to provide peace of mind for prospective property purchasers. GWE can undertake condition assessment of existing treatment systems and provide advice for future development and change of land use.

Wastewater Treatment

GWE works in partnership with New Zealand’s leading wastewater system suppliers to offer affordable solutions that meet your individual needs. We provide designs specific to our client’s needs and site conditions including:

  • Primary treatment – grease traps, septic tanks and effluent filters
  • Secondary treatment – aerated treatment systems, activated sludge, bio-filtration, trickling filters and packed bed reactors
  • Tertiary treatment – UV, chlorine, ozone disinfection
  • Alternative systems – greywater reuse, composting systems

On-site Disposal

A range of options are available for the on-site disposal of treated wastewater. GWE have experience with the design of:

  • Pumping and siphon controlled distribution systems of treated wastewater
  • Shallow irrigation systems including drippers, subsoil, and spray irrigation
  • Conventional irrigation trenches, mounds and beds

Resource Consenting

Many on-site wastewater systems will require a regional resource consent for the discharge of wastewater onto land. GWE prove our clients with advice on the resource consent requirements and produce technical and planning reports – including assessment of environmental effects (AEE) to support resource consent applications for new and renewal of on-site wastewater systems.
