Overview

Completion of Stage 2 Upgrade to the Paxton WWTW

The Stage 2 upgrade to the Paxton Wastewater Treatment Works has been completed. The upgrade to the WWTW included Hunter Water's first successfully commissioned membrane bioreactor (MBR).  MBR is advanced membrane technology which provides a more robust treatment process and reduces the amount of phosphorous in treated effluent.

The upgrade will provide additional treatment capacity to service unsewered homes at Millfield and Ellalong which will allow residents to replace port-a-loos, septic tanks and other on-site wastewater disposal systems. The upgraded WWTW will also service new homes at Paxton, Millfield and Ellalong and will cater for anticipated commercial and residential growth in the next 20 years.

A water quality and aquatic ecology monitoring program and effluent reuse investigations are currently underway at Paxton WWTW. Hunter Water will utilise outcomes from the monitoring program and effluent reuse investigations to assist in developing the long term effluent management strategy for the Paxton WWTW. Input from the community and other key stakeholders will be invited to inform this process. A decision regarding the most appropriate long term effluent management strategy for the Paxton WWTW is anticipated by the end of 2013.

Future Plans

Planning is now underway to develop a long-term effluent management strategy. Hunter Water has commenced investigations to determine the most sustainable long-term effluent management strategy for the Paxton WWTW.

We currently reuses some of the treated effluent on site to irrigate an existing tree plantation, with the remainder discharged to Congewai Creek.

In 2004, we assessed potential additional recycled water opportunities from the WWTW as part of the Review of Environmental Factors (REF).

A number of studies were conducted covering a variety of perspectives including woodlots, irrigated pastures and crops, and option studies.

The reuse investigations concluded that there was limited potential for a recycled effluent scheme from the plant.

However, we have now commenced additional effluent reuse investigations to review the findings of previous effluent reuse investigations and assess the feasibility of new reuse opportunities.

The results will be incorporated into a sustainable decision making process with the aim of determining the most appropriate solution for the community and environment.

We will be seeking input from the community and other key stakeholders to inform this process.

A decision regarding the most appropriate long-term effluent management strategy for Paxton WWTW is anticipated by the end of 2013.

Reuse Investigations - May 5, 2011

Consultants have commenced preliminary reuse investigations as part of Stage 3 future planning activities, one being the suitability of Hardy Holdings land adjacent to the site. Soil sampling of this site is currently underway. These investigations will feed into future re-use options.
