Watercare provided an update on the South-West Wastewater Servicing Scheme last night at a meeting in Glenbrook!

Watercare had been busy reassessing options over the past year and shared its preferred solution for wastewater servicing in Kingseat, Clarks Beach, Glenbrook Beach, and Waiuku.

After extensive community feedback and detailed analysis, Watercare's preferred option was a decentralized scheme (Option 3) utilizing existing Clarks Beach and Waiuku sites. This approach was designed to service up to 29,000 "population equivalent" (PE) and offered several benefits.

What this means for our communities:

* Clarks Beach: Will have a more permanent Wastewater Treatment Plant (WWTP) with a capacity of up to 9,000 PE.

* Waiuku: A new WWTP with a capacity of up to 20,000 PE will be built.

* Glenbrook Beach & Others: A treated effluent conveyance pipeline will run from Waiuku to Clarks Beach.

This preferred option better aligned with updated population growth projections, which are slower than previously anticipated. It made use of what has already been built at Clarks Beach, avoiding starting from scratch. It was also more aligned with feedback from the community and independent commissioners and required less new consenting. Watercare stated it reduced their spend at the time, aligning better with projections for when growth would occur, and future-proofed the area with room to scale up as needed.

Watercare was in the planning phase at the time of the announcement. Initial steps included the construction of permanent tidal storage at the existing Clarks Beach WWTP site and making this plant more permanent. An interim upgrade of the existing Waiuku WWTP was also planned, along with the design of the new Waiuku WWTP and the conveyance infrastructure. Additionally, Watercare would be looking into renewing and upgrading the local wastewater networks in Clarks Beach, Glenbrook Beach, and Waiuku to meet current and future needs.

WASTE TREATMENT PLANT UPDATE - Please have your say!

Watercare recently held community events at Clarks Beach, Glenbrook Beach and Waiuku touting new options for future wastewater servicing in our communities.

Disappointingly, three of these 'options' include building a poo plant on the land at 372 Glenbrook Beach Road. This is despite the independent commissioners advising Watercare at a hearing that they could not use this land for wastewater treatment purposes. Watercare accepted this decision, yet here we are with more stubborn short-sighted decision making from them.

PLEASE provide feedback to Watercare on what option/s you think are a great idea, and which ones you think stink.

You can email them at [email protected] (they are presenting the short list on 18, 19 and 20 March so get in before then!).

We don't want to tell you what to do, but if it's a bit tricky to get your head around the info, or if you just want someone to steer you in the right direction, we reckon Option 3 looks like a pretty good choice:

- It keeps the Tasman Sea discharge option on the table.
- Involves poo plants at Clarks Beach and Waiuku on land already owned by Watercare and used for waste treatment purposes.
- No raw sewage pump stations.
- Only one pipe (cheaper and less road disruption) however, we should really be encouraging Watercare to put the pipeline in the Harbour like they already do between Clarks Beach and Glenbrook Beach.
- Note, each option meets the supposed need for increased capacity for future growth and that the wastewater produced at all plants will be of equal quality.
