Water Main Replacement Waikato

A damaged or ageing water main can lead to costly leaks, reduced water pressure, and even property damage. At The Leak Detection Company we partner with our sister company Trench Right, to provide expert water main replacement services across the Waikato – delivering fast, reliable solutions to restore your water supply and prevent ongoing issues.

When to Consider Water Main Replacement

You may need your water main replaced if you notice:

  • Frequent leaks or repairs on the same line

  • Low or fluctuating water pressure

  • Discoloured or rusty water

  • Pipes made from outdated or unsafe materials

  • Signs of corrosion or pipe collapse

If you’re unsure, our team can carry out a water main inspection to confirm whether a full replacement is the most cost-effective option.

Our Water Main Replacement Process

Assessment & Planning – We locate and assess your existing water main, noting its depth, material, and condition.

Leak Location & Marking – Using advanced pipe location and leak detection technology, we map the full line to avoid unnecessary excavation.

Safe Removal – The old water main is carefully removed or decommissioned.

New Installation – We install a high-quality, durable replacement pipe that meets NZ building and plumbing standards.

Testing & Backfilling – The new main is pressure tested to ensure a secure, leak-free supply before the site is reinstated.

Terms & Conditions

Disclaimer – Please Read Before Engagement

This agreement outlines the terms under which The Leak Detection Company provides underground water leak detection services to the person or organisation engaging us (“you”).

You acknowledge that our services are designed to assist with the identification of potential underground water leaks and buried services. While The Leak Detection Company utilises the latest technology and industry-accepted best practices for underground leak detection, we cannot guarantee a detection survey will result in the positive location of any/all leaks. This is subject to several factors that are out of our control, including but not limited to ground conditions, external noise sources, pipe/leak depth and leak size/volume. 

No assurance can be given about the exact location of any underground leak or utility identified by The Leak Detection Company. The only way to confirm any such finding is through visual verification. (Refer: AS 5488.1.2019 – Subsurface Utility Engineering (SUE), Quality Level A).

The accuracy of our detection tools and techniques can vary. Any positions or depths indicated should not be considered exact. You are responsible for confirming all positions and depths using hand digging or hydro excavation methods prior to any mechanical excavation.

The Leak Detection Company accepts no responsibility for any damage, disruption, or harm caused to underground services, or for any injury, financial loss, or other consequences resulting from such incidents—whether affecting you or any other party such as contractors, owners, customers, service providers, councils, or others. You agree to fully indemnify The Leak Detection Company against all such claims, damages, and associated costs.

If, despite the above, any liability does arise on the part of The Leak Detection Company (in contract, tort, or otherwise), that liability will be limited to the total amount paid by you for our services. We are not liable for loss of income, contracts, business opportunities, or any indirect or consequential damages.

These limitations and protections extend to all staff, agents, officers, and contractors of The Leak Detection Company.

You acknowledge that this document forms the entire agreement between you and The Leak Detection Company, and no other terms, representations, or assurances—unless documented here—are part of the agreement.
