Cover story: Contained services for conurbation
Nestled between two national parks in Queensland lies the conurbation of Agnes Water and Seventeen Seventy where Captain James Cook first came ashore along the northern coastline. This article details the need for integrated water services through the area and the works to be involved in the water and wastewater augmentation project.

Cover story: Valley of potential
With an outlook for continued strong population growth in southeast Queensland, options for future water supply include tapping into the high-yield potential that exists with building a dam in the Mary Valley. Preliminary design and environmental assessment processes for this option continue. Water Engineering Australia takes an engineering snapshot of the project to date.

Cover story: Treatment in a remote community
A shire council in rural NSW has developed a scheme for the tertiary treatment of sewage for a remote community that was previously serviced by septic systems. By combining low pressure sewage grinder systems with an intermittent decant extended aeration sewage treatment plant, the system is monitored remotely and operates with minimal operator attendance.

Cover story: Banking on recharge
After five years in development, the $10.4 million Wateer Reuse in the Alice project was full commissioned by Northern Territory's Power and Water Corporation in May. The project features an upgraded water reclamation plant and a 6.2km pipeline to a series of infiltration basins for managed aquifer recharge. The pilot project will be thoroughly monitored to provide essential information for the development of national guidelines for water recycling.

Cover story: Military engineers avert disaster
The cover photo, released by China's Xinhua News Agency, shows the drainage of the Tangjiashan quake lake, in southwest China's Sichuan Province on Tuesday 10 June. A lake was formed by massive landslides from the 12 may earthquake blocking the Tongkou River flow. The level of the lake swelled through the month of May as soldiers rushed to construct a diversion channel to drain the rising waters.

The cover story takes a close look at 'Threading pipelines under a river'. The southeast Queensland Water Grid has moved a step closer to completion following the major crossing of water channels along the pipeline route. Contractors used horizontal directional drilling technology to bore under the river bed and thread the pipeline through, minimising surface disruption in an ecologically sensitive area.

The cover story take a look at 'Desalination discharge: The case against dissolved oxygen depletion'. Prior to the construction of Australia's frst major desalination plant in Perth there was public concern for the effects of the discharge of desalination concentrate, specifically the extension of stratification events and resultant dissolved oxygen depletion. After more than $1 million of studies monitoring the dissolved oxygen levels in Cockburn Sound, the Water corporation has released a report stating that dissolved oxygen trigger levels for management intervention are not required.

The cover story of the April issue take a look at 'Project Contamination Cleanup'. One of Australia's largest pump and treat projects continues at Botany Bay Industrial Park in Sydney. After decades of industrial contamination to the underlying aquifer, Orica has built a $110 million extraction well network and treatment plant, to treat an average of 5ML/d of groundwater. The plant is designed to operate for 30 years and refinements to the process continue, one such example being a lower operating temperature for the thermal oxidiser which was revised late last year.

The cover story of the March 2008 issue take a look at 'Sourcing urban alternatives'. With a plan to provide dual reticulation systems to all new reidential developments in the Port Macquarie-Hastings area, the local council has led by example and introduced recycled water within existing urban areas to aid the education and promotion of recycled water schemes. It is a project that was widely recognised for its excellence with a number of awards late last year.

December 2007

The cover story of the December issue takes a look at the planning behind a 450GL dam proposal for the Hunter Region that plans to secure water for the growing region for 60 years. Other stories include an Engineers Without Borders water project in Bali, and a wastewater improvement project for Townsville that will reduce the nutrient loading in the receiving waters of the Great Barrier Reef. The magazine also includes a feature on the growing practice of sewer mining – providing small decentralised wastewater treatment plants to create recycled water opportunities to areas previously considered unviable to supply due to the pipeline distance to the main wastewater treatment facilities.

November 2007

The cover story of the November issue of Water Engineering Australia takes a close look at a greenfield development on the Gold Coast, Queensland to find out about the integrated water management approach that aims to reduce potable water consumption by a staggering 84%. Other issues covered include desalination for small communities and guidelines for managed aquifer recharge. The magazine also includes a feature on the value of metering and monitoring water use to better understand water consumption patterns.

October 2007

The first cover story of Water Engineering Australia examines the Western Corridor Recycled Water Project in south east Queensland, Australia’s first planned major indirect potable reuse project that produced its first water in August for use in a nearby power station. Other articles in the publication cover topics such as the groundwater replenishment scheme in Orange County, US, and the possible structure of a Water Futures Market on the Australian Stock Exchange. The magazine also includes a focussed feature on stormwater modelling software.
