Background
To ensure that the people of Tauranga have access to high-quality water, the City Council is committed to the continuing management, upkeep, and development of the drinking water supply catchments and water treatment operations. The Tautau and Waiorohi streams are the two natural springs from which our city draws water.
Objectives and Constraints
Tiaki Engineering Consultants were engaged by Tauranga City Council to design an additional 10-megaliter reservoir to supplement the existing reservoir at the Joyce Road Water Treatment Plant. This project would result in a doubling of the current storage capacity at the water treatment plant to ensure the resilience of the infrastructure and an uninterrupted water supply. The reservoir measures 46 metres in diameter and is mostly buried below the final ground level. The water-retaining structure comprises precast concrete walls with in-situ concrete floors, wall stitch joints, and an aluminium geodesic dome roof, allowing a columnless design.
The project required careful sequencing, incorporating a complex and substantial amount of earthworks, and temporary shoring. As part of the project, new interconnecting chambers and pipework for the reservoir inlet, outlet, overflow, and scour were installed. This was done in collaboration with the Tauranga City Council to ensure that the existing supply was not interrupted or contaminated during the construction and tie-in process.
Project Outcomes
Our team proudly partnered with the Tauranga City Council in this endeavour. We are adapting to keep up with Tauranga’s growth, with daily water needs ranging from 44 to 58 million litres. Modern microfiltration technology at Joyce Road Reservoir guarantees crystal-clear water quality. The project’s effective completion within the allotted timeframe serves as an example of the Tiaki team’s outstanding accomplishments.
