Small Wastewater And Natural Systems (SWANS)

Welcome to the homepage for Water New Zealand's Small Wastewater And Natural Systems Special Interest Group (SWANS-SIG)

Background

SWANS-SIG has been set up to represent the interests of Water New Zealand members involved in research, practice and administration in the small wastewater flows area. It encompasses interest in all aspects of on-site domestic wastewater systems through to small community wastewater servicing, and includes the use of natural systems such as waste stabilisation ponds, constructed wetlands and land treatment processes in managing small wastewater flows within the environment.

The aims and objectives of SWANS-SIG include:
  • to provide a forum for interaction and discussion between participants in the small wastewater and natural systems industry
  • to facilitate the exchange of information between members and related organisations and agencies
  • to assist development of and provide support for training programs for participants in the small wastewater and natural systems industry
  • to organise seminars, workshops and other meetings to support the objectives of the group; and to promote education and public understanding of small wastewater and natural systems issues.

On-Site Effluent Treatment (OSET) National Testing Programme (NTP)

This SWAN-SIG initiative was started in 2008 with the intention of introducing a national testing programme for assessment of the performance of domestic on-site wastewater treatment plants. The project is well underway, with the upgraded facility commencing its first national testing run with Trial 4 (November 2008 to July 2009), the second run being Trial 5 (November 2009 to July 2010).

On-Site NewZ

“On-Site NewZ” is a newsletter and information service for the on-site domestic wastewater industry in New Zealand. It began as a quarterly newsletter in 1996 to provide update information on design practice and new technologies as a support service to users of TP 58, the Auckland Regional Council’s 1994 design manual for “On-site Wastewater Disposal from Households and Institutions”. As well as producing four issues of the newsletter each year, On-Site NewZ provides from time to time a range of ‘special reports’ dealing with summaries of conference proceedings/discussions, and coverage of latest information on technical issues related to on-site wastewater servicing.

On-Site NewZ Information Services has produced a “Directory of Manufacturers/Suppliers of On-site Domestic Wastewater Treatment Plants, 2010”. This Directory lists those companies supplying residential domestic wastewater treatment units in the NZ market, and indicates which systems have undergone performance testing at the Rotorua based OSET NTP.

On-Site Wastewater Special Interest Group (OSW-SIG)

OSW-SIG is an affiliated sub-group of SWANS-SIG, and consists of representatives of on-site wastewater treatment plant manufacturers who have as their goal “to raise the standard of on-site wastewater manufacturers and influence councils regarding quality on-site practices and standards”. OSW-SIG has maintained a presence on the committee reviewing joint Australia/NZ standards for on-site wastewater systems, and has supported the production and distribution of the On-Site NewZ booklet “On-site Wastewater Systems – Selecting a System for Your Property”.

This information booklet for homeowners explains modern approaches to on-site systems, the treatment and land-application systems now available, and the process of selecting, installing and maintaining a system for long-term sustainable wastewater servicing.
