Lyell Creek Sewer
Our sewer infrastructure was badly damaged by the 2016 earthquake, including damage to several wastewater pump station structures, rising mains and gravity sewers along Lyell Creek.
This sewer takes a large percentage of the wastewater for the whole of Kaikōura township. The repair and replacement of the sewer is the largest project in the horizontal infrastructure rebuild at an estimated $6million.
The project involves replacing about 3km of wastewater reticulation from Lyell Creek pump station to the Mill Road pump station. A new sewer line will be installed along Beach Road and include pressure sewer collection tanks to service properties between Beach Road and Lyell Creek. A number of meetings and home visits with affected community members and stakeholders have been held to help home owners understand what this means for them.
The project runs from Lyell Creek pump station all the way up to Mill Road pump station (a length of about 2.9km). The sewer is the main sewer line for the township of Kaikōura and is therefore one of our most critical assets. We have looked closely at the damage that was suffered during the earthquake and have a much better understanding of what that means. The most damaged sections of the pipe are from the Hawthorne Road Bridge up to Mill Road pump station. Less damage was seen between Lyell Creek pump station and Hawthorne Road, but there is still work to be done in that area.
Once we understood all the damage, we considered a number of options for how best to fix the pipe. After evaluating each option against a wide range of criteria, it was decided that the best option was to replace the entire current sewer system and relocate it to Beach Road. The benefits of this options include ease of construction, minimal disruption to home owners, low visual impact, new technology, cost effective for initial installation and long term maintenance, and the most resilient option for future environmental events (more flexible for future earthquakes).
Council continues to work with affected residents and home owners. If you have questions regarding the Lyell Creek Sewer upgrade, please email firstname.lastname@example.org

Currently the project is in detailed design stage. The preferred design is being drawn up in detail, so that contractors can provide costs and plan the construction methodology and programme.
Detailed design should be complete by mid-October 2018. The contract should be awarded by Christmas 2018 and construction should start in January 2019.
Construction is expected to take just over 12 months and should be complete by March 2020 with the handover of the asset completed by June 2020.
We are very mindful that Kaikōura’s busiest time of the year is over the summer and this has been factored into the construction works programme. In terms of impacts to Beach Road, we are going to need to work to make sure those impacts on the town are minimal for the community. Will Doughty, Rebuild Director

As a result of the earthquake, the existing gravity sewer along Lyell Creek was badly damaged. Council and its rebuild funding partners have determined that a pressure sewer system is the best option for a sustainable and resilient system to service the Beach Road area into the future.
To discuss this with the community, Council arranged for a public meeting in April 2018, which was held to inform residents of the pressure sewer system being installed in Lyell Creek. A further update has now been provided on the pressure sewer system proposed for houses near the Lyell Creek catchment.
Council have appointed Stantec as the consultant to carry out the design, and to undertake the consultation with the affected parties (including property owners and occupants). The new system is currently being designed and further information will be available as the design progresses.

We are working with property owners along Lyell Creek to understand the land damage caused by the earthquake and what this means for properties.
Part of this work is setting up one-on-one meetings with around 50 property owners along the creek to talk through the situation and understand more about their plans.
Chief Executive Angela Oosthuizen says Council staff have been working closely with the Crown, Environment Canterbury, EQC and other agencies to understand the land damage and how it may affect properties and infrastructure in the long-term.
“It’s important that we involve property owners in our discussions so we understand what the community thinks about the situation and their wishes for the future.
“No decisions have been made about what, if anything, needs to be done to address the most significant areas of land damage along Lyell Creek. We need to hear first from property owners before we consider the various options,” she says.
Early geotechnical investigations indicate some significant land damage near the creek, such as bank collapse, lateral spread and land stretching on properties along the creek’s edge. It’s not likely that it will be cost-effective to repair buildings on properties affected by the most significant damage. The Council will work through what happens next with these property owners.
Properties with less damage will be able to push ahead with earthquake repairs. Additional building consent requirements may be necessary for rebuilds or future structural work on these properties.
“The nature of the land damage means the situation will vary from property to property so we’re talking through the specifics with property owners.”
Lyell Creek is one of a number of areas across the district affected by natural hazards as a result of the earthquake. The Council is working through investigations in all of these areas and will be talking in more detail to other property owners soon.
