Seadown Water Scheme Upgrade

Water Supply


Back in January 2022, consultation was done regarding the future of the Seadown water supply.

We received a total of 59 submissions and it was great to see thoughtful consideration of the issues. The feedback we received was consistent with the discussions at our in-person meetings held in November 2021, which over 100 people attended. (Please see the full consultation document and results below)

Based on feedback, Council decided at its Infrastructure Committee meeting on 26 August 2022 to reconfigure the scheme over time to convert it to a fully restricted trickle-feed supply. This will address the issues of equity and fairness, while also improving scheme performance in terms of flow and pressure, and will make it consistent with Council’s other rural water supplies such as Te Moana and Downlands.

These changes to the scheme were proposed to be developed and coordinated with scheduled asset renewals over an extended period of time, such as the next 10 years.

What's happening now?

Work will shortly begin to install the new trunkmain that will supply the Seadown scheme. We will be reaching out to the residents and landowners that are affected as part of Stage One of this upgrade with the next steps and what will be required going forward.

Once the installation of the trunkmain is established we can proceed with engaging with residents of stage two. (the rest of the scheme)

Frequently Asked Questions

I have a question that I can't find the answer to, how do I get in touch?

Please email all enquiries to and we will be in touch as soon as possible.

What size water supply tank will I need?

A minimum of 10,000 litres or 3 days storage supply on your current allocation, whichever is greater. Use the water supply calculator below to determine your supply.

I currently have troughs on my property that are directly connected to the Seadown scheme watermain, can they remain?

You may keep the number of troughs you have but they must be supplied directly from your one principal tank.

 Will I need to relocate my tank or install a pump?

Possibly, this will depend on your individual set up. At this stage we are aware that the best location for your tank would be as close to the roadside of your property boundary, adjacent to the main as possible. If you have questions on this send them to

I need to install a new pump or have my current one relocated, who can do this?

It is essential that a Council approved contractor does this. To find a list of suitable contractors visit: (Refer to the contractors highlighted in green for the work required)

How much water am I entitled to?

65 litres per hectare per day for stock water, with an additional 1,000 litres per dwelling per day. To work out the maximum number of units you’re eligible fo, use the water supply calculator below under "Resources".

Was this consulted on?

Yes, please see the 2022 consultation document here:

and the consultation results here:

Will you be digging up my property?  

No,  the installation of the new pipes will be within  the road corridor.

 When do I need to have the works on my property completed by?

Stage one properties are required to be hooked up to the new main by July , 2025.

Stage two completion date is undetermined at this time.

Why does the scheme need to change? 

As it is currently, the Seadown water scheme doesn't meet the standards set by Taumata Arowai, New Zealand’s water regulator. These upgrades will ensure that all properties are connected to the same scheme style as other rural schemes managed by Timaru District Council. This will improve scheme safety, address demand issues, and ensure there's consistent water for all users.
