Kepa Road wastewater system improvements

• Project typeWastewater system repairs
• Project scheduleStage 4: October 2024 to June 2025
• Completion Date30 June 2025

The wastewater system in the Kepa Road area in Ruakākā carries wastewater from several locations to a pumping station on Sime Road. 

From there, the wastewater is pumped to the Ruakākā Wastewater Treatment Plant.

Timeline of issues

In early 2023, Council’s Waste and Drainage Department was alerted to the fact that sections of this wastewater system had failed in the area. Following investigations, it was decided that the faulty parts of the gravity wastewater pipeline and faulty manholes in the area would be repaired as a matter of urgency.

Sections were repaired in stages and, by the end of 2023, stages 1, 2 and 3 had been completed.

Further evidence of faulty pipes and manholes was brought to Council’s attention in December 2023.

Planning for Stage 4 commenced shortly after this with physical repair works starting at the beginning of October 2024 and remediation was completed in June 2025. In the interim, wastewater flow control was managed through bypass pumping.

What we did

We:

• replaced the faulty concrete pipeline with polyethylene and PVC pipelines
• installed new manholes to replace faulty ones where they were not salvageable
• coated existing manholes where they did not need replacing to protect from corrosion
• kept the area clean
• put up signs to alert people to the ongoing works
• kept a back-up pump on-site to help bypass the problem area when needed
• monitored flow levels in parts of the wastewater system and prevented any spills
• kept affected parties updated on progress, including NRC, DHB, and nearby property owners.
