This paper highlights the challenges of reducing operational energy costs at a large water utility and the exciting possibilities presented by ever-more affordable distributed electricity generation technologies such as solar PV and battery storage, as well as next-level wastewater treatment technologies that optimise the production and use of biogas.
This paper outlines both the Ice Pigging process and the many advantages to the technique. Further to this it will look in detail at several Ice Pigging projects undertaken by Suez that demonstrate these economic, operational and reduced customer impact benefits.
This paper will help water authorities understand how the standards can be applied to their organisations in a manner that provides the national consistency intended by the standards whilst addressing the particular characteristics and challenges of individual networks.
This paper will describe a major asset capitalization project undertaken with Waipa District Council in which conventional (manual) data entry workflows were replaced with data automation and systematic verification processes.
This paper will discuss evolution of Advanced Metering Infrastructure (AMI) technologies, presenting examples from projects around the world relevant to New Zealand’s unique water environment.
This paper summarises recent case studies describing four emerging approaches to reducing wetland area through process intensification: super-oxygenation for nitrification, zeolite-anammox media filtration for deammonification, biochemical reactors for denitrification, and geochemical augmentation in surface flow (SF) wetlands for phosphorus removal.
This paper will discuss the collaborative safety in design approach, contracting approach and the breakdown of traditional barriers, from concept design through the six major phases to operational handover.
The quantity and quality of water supply is always a significant concern following an earthquake. Water for drinking and cooking is vital, and it is also needed for firefighting, medical systems, and post-earthquake reconstruction.
When a natural disaster strikes, the immediate and necessary response is to get the systems back up and running as quickly as possible. However, soon after the initial response effort, the funding of the response and recovery phases becomes an obstacle that must be addressed.
