For engineers tasked with maintaining our vital water infrastructure, the choice of cleaning method is critical. We’re not just looking for efficacy; we need solutions that align with our commitment to sustainability, minimal environmental impact, and responsible resource management. In this context, a comparison between NO-DES and ozone cleaning reveals significant advantages for NO-DES, particularly in…
Water utilities in Australia and New Zealand face the ongoing challenge of maintaining the integrity of their vast pipeline networks. Pressure transients are typically triggered by rapid changes in flow, such as pump start-ups or shutdowns, valve operations, or unexpected system failures. Pressure transients are known to cause the majority of pipe bursts, significantly reduce…
Inflow and infiltration (I&I) in wastewater networks pose significant challenges for water utilities and councils across Australia and New Zealand. Traditional methods of detecting and managing I&I are often time-consuming, costly, and require substantial manpower. However, advancements in technology offer more efficient solutions. By creating mini-catchments and deploying smart sensors, utilities can revolutionise their approach…
In the pursuit of optimising infrastructure management and ensuring the reliability of its water supply network, a leading water utility in Australia had initiated a comprehensive pipeline rehabilitation and replacement project on what it described as “one of the most critical assets in their entire water network.” This approach, while straightforward, often leads to unnecessary…
Water utilities and councils across Australia and New Zealand face the ongoing challenge of maintaining clean and efficient water distribution systems. Traditional methods like flushing, air scouring, pigging, and ice pigging have been mainstays, but an innovative technology called NO-DES (Neutral Output Discharge Elimination Solution) is emerging as a superior option. Why is NO-DES a game-changer…
Water utilities and councils worldwide face a monumental task: managing extensive networks of water pipelines that span hundreds of kilometers. Yet, amidst this challenge lies a critical opportunity—an opportunity to revolutionise pipeline management through proactive and strategic measures, starting with condition assessment. Why Condition Assessment Matters The ageing infrastructure of water pipelines, often comprising various…
When it comes to water and wastewater management, the battle against inflow and infiltration (I&I) poses a significant challenge for municipalities and water utilities globally. I&I occurs when groundwater or stormwater enters sewer systems through leaks, cracks, or faulty/illegal connections, leading to overwhelmed treatment facilities, increased costs, and environmental concerns. To address these issues sustainably, innovative…
