Foreword and Acknowledgements

The New Zealand Waste Strategy, launched jointly with Local Government New Zealand last year, identified the need to complete and publish a Sewage Treatment Handbook for small communities.

Coastal settlements, small towns, and low-density rural settlements will all face wastewater management decisions at some time. The issues are complex and challenging, and finding solutions will involve thinking about how big the community will grow, what kind of community it will be, how clean the local stream or estuary will be, even the layout and form of the settlement.

Sustainable Wastewater Management: A handbook for smaller communities, provides a framework to assist small communities identify and evaluate alternatives for improving sewage treatment and disposal. The aim of the handbook is to help communities understand and navigate the issues, plans, legislation, and technical advice provided by consultants.

The government's Sanitary Works Subsidy Scheme will assist small communities to upgrade substandard wastewater treatment facilities and provide a healthier environment. This handbook has been designed to help everyone get involved in the process.
