SurePave Case Study | Balmoral-Tuapeka Water Treatment Plant

The Balmoral-Tuapeka Water Treatment Plant is a newly constructed facility that draws raw water from the Clutha River to supply treated drinking water to the local community. Completed in 2025, the project included the installation of a new intake system designed to ensure resilient and reliable water supply.

As part of the overall site development, surface improvements were undertaken around the car parking areas, tanks, and supporting infrastructure to create a durable, safe, and environmentally responsible operational environment.

The Problem

As a new-build facility, it was critical that the yard areas surrounding the tanks and intake equipment were designed to withstand long-term operational demands from day one. These areas needed to support heavy vehicle access, resist erosion, and prevent water pooling.

Without proper surface reinforcement, exposed ground could quickly become uneven, muddy, and prone to wear. This would create safety risks for staff, restrict heavy vehicle movement, and increase long-term maintenance requirements. Stormwater runoff also posed a potential environmental risk, particularly at a site responsible for delivering safe, clean drinking water.

The installation of intake infrastructure required a stable surface capable of supporting heavy lifting equipment and delivery vehicles. Health and safety was a key consideration, as a firm, mud-free environment reduces the risk of slips, trips, and falls around tanks and operational areas. Environmental management was equally important, with permeable paving identified as a practical way to manage stormwater on-site and reduce the risk of pollutants entering nearby waterways.

The Solution

SurePave was selected as the surface reinforcement system for the new facility due to its ability to meet the unique demands of a water treatment plant. Its permeable design allows water to infiltrate naturally, preventing puddling and excessive runoff – particularly important at a site with regular vehicle traffic and environmental sensitivities.

By enabling stormwater to filter through the ground, the system helps reduce the risk of oils, chemicals, or other contaminants being washed into the Clutha River.

SurePave is strong and durable. Its cellular structure distributes heavy loads evenly, preventing ruts and potholes from forming under constant vehicle use. The system was filled with angular 8mm–20mm aggregate, creating a firm, stable surface suitable for both foot traffic and heavy machinery. This enhanced the functionality of the plant’s operational areas while improving site safety and cleanliness.

The system can be easily cut and installed around tanks, pipe inlets, and other infrastructure, ensuring a neat and integrated finish. Made from recycled materials, SurePave aligns with sustainable construction practices and offers long-term, low-maintenance performance compared with traditional paving options.

The Result

The completed surface installation has delivered a modern, resilient yard area that supports the performance of the new Balmoral-Tuapeka Water Treatment Plant. The reinforced SurePave system provides a permeable yet stable surface capable of withstanding heavy vehicle traffic while remaining safe for staff movement.

By reducing runoff and allowing water to infiltrate naturally, the solution contributes to a cleaner operating environment and minimises environmental impact.

Around the tanks and pipe inlets, the SurePave surface has created a tidy, accessible area that enhances operational efficiency. Staff can move confidently across the site, while vehicles benefit from reliable access even in wet conditions.

The Balmoral-Tuapeka Water Treatment Plant now balances strength, sustainability, and practicality – ensuring the facility is built to perform for the long term.
