REACTIVE SOILS CAN BE VICIOUS Des Grevell – Storm Plastics
+Abstract
When we talk about reactive soils, we don’t mean reactive soils as in radio–active soils from a nuclear test site or a toxic waste dump.
While that type of soil may be detrimental or even deadly to health the effect of the reactive soils discussed here can be destructive to buildings and the underground pipes and fittings used to service these buildings, be they large commercial buildings or domestic houses, herein we will only discuss the latter.

BE CAREFULL WHAT YOU WISH FOR- IMPLEMENTING A FILTER INSPECTION PROGRAM John Day – Goulburn Valley Water
+Abstract
As stated in the publication of A Practical Guide to the Operation and Optimisation of Media Filters “filtration is arguably the key process unit in a Water Treatment Plant” In recognising the truth of this statement and to improve the reliability and water quality out of our filters at Goulburn Valley Water, Peter Mosse was engaged to develop a regular inspection program and to train operators to undertake this program. This paper will cover the implementation, results and ongoing outcomes of setting up the system of inspection. The paper will also address, putting together an Action plan, and will cover some of the actions that were implemented.

WATER MANAGEMENT IN REAL TIME – KNOW EXACTLY THE ‘WHEN, WHERE & WHY’ OF YOUR WATER CONSUMPTION Robert Kelso – Australian Metering Solutions
+Abstract
Automatic meter reading, or AMR, is the technology of automatically collecting data from a water or energy meter and transferring that data to a central database for billing and/or analyzing. This saves employee trips, and means that billing can be based on actual consumption rather than on an estimate based on previous consumption, giving customers better control of their use of electric energy, gas usage, or water consumption. AMR technologies include handheld, mobile and network technologies based on telephony platforms (wired and wireless), radio frequency (RF), or powerline transmission.

CASE STUDY: BIO-AUGMENTATION OF DRU POINT WASTEWATER LAGOON AT MARGATE, TASMANIA Craig Griggs – Kingborough Council
+Abstract
The Dru Point wastewater lagoons are located at Margate in the Municipal of Kingborough, Tasmania. Kingborough is located south of Hobart with Margate situated as a satellite township around 10 km below the main Civic Centre of Kingborough.

SEPTICITY OCCURRENCE & MITIGATION WITHIN WASTEWATER TRANSFER SYSTEMS Chris McLaughlin – BioRemedy
+Abstract
The occurrence of septicity within wastewater transfer systems often requires a significant investigative approach to determine the appropriate mitigation response. Septicity of sewage is generally related to extended retention within wastewater transfer systems. Potential effects of septicity, simplistically, are, generation, and emission, of odour to atmosphere, and, eventual infrastructure degradation, by way of formation, in situ, of corrosive compounds.

DEALING WITH TASTE AND ODOUR PROBLEMS ARISING FROM ALGAL BLOOMS IN A RAW WATER RESERVOIR Chris Keogh – Armidale Dumaresq Council
+Abstract
Malpas Dam is Armidale Water Treatment Plant’s primary source of raw water. Since its construction there have been problems with algae, with a number of significant blooms occurring almost every year. If not dealt with these blooms cause taste and odour problems in the treated water and in the extreme may have an impact on human health.

INVESTIGATION INTO ALTERNATIVE METHODS OF TREATING AN ALGAE CONTAMINATED WATER SUPPLY Paul Thompson – Hunter Water Australia
+Abstract
Following on from a small scale investigation when water from Armidale was put through an offsite pilot plant, Hunter Water Australia (HWA) entered into an agreement with Armidale Dumaresq Council to determine the preferred long term treatment strategy for treating water from the Council’s Malpas Reservoir. The supply from this reservoir is affected by algal blooms, especially during the summer, and the Council were looking for a treatment process that would effectively and reliably remove organic contaminants such as algal toxins and taste and odour compounds from the water.

DESIGN AND CONSTRUCTION OF AN OZONATION FACILITY AT AN EXISTING WATER TREATMENT PLANT Andrew Boeren – Bricon
+Abstract
Bricon was selected to provide a tender for the design and construction of an ozonation plant to be located alongside Armidale’s existing Water Treatment Plant.

PRACTICAL ISSUES IN COMMISSIONING A SIMPLE STORM WATER HARVESTING SYSTEM FOR WATER QUALITY Gordon King – B2P Australia
+Abstract
Ku-ring-gai Council in Sydney has been very active in promoting water harvesting and re-use schemes. The St Ives Bowling Club decided to install a storm water harvesting system to replace their reliance on town water as previous drought restrictions had caused damage to some greens. Their Development Application required water quality testing to occur over a six week period which included sampling after at least one high rainfall event. The E. coli levels had to comply with the NSW DECC Level 3 guidelines (<1000/100ml).

CCTV INSPECTION OF SEWERS AND STORMWATER DRAINS, TRAINING OF OPERATORS AND MANAGERS, AND THE CONDUIT INSPECTION REPORTING CODE OF AUSTRALIA Steve Weatherstone – Streamline Learning
CONDITION ASSESSMENT TECHNIQUES FOR WATER STORAGE TANKS Sam Magill – Aqualift Potable Diving
+Abstract
The majority of water utilities have some form of water storage tanks, most often constructed from steel or concrete. These tanks are an integral part of the potable water distribution network but are often taken for granted from a maintenance and condition assessment point of view.

TARCUTTA TREATMENT PLANT IRON AND MANGANESE REMOVAL Peter Outtrim – Riverina Water County Council
+Abstract
Upgrade to the Water Treatment Plant at Tarcutta village. The upgrade was necessary to achieve removal of soluble iron and manganese from the source water prior to chlorination of the village supply. Focus on the process which we went through to find suitable technologies for this removal.

WELL, WELL, WELL – DRIFT WELL RECOMISSIONING, AN OPERATORS PERSPECTIVE Adrian Cameron – Tamworth Regional Council
+Abstract
Tamworth is located approximately halfway between Sydney and Brisbane on the New England Highway. It is recognised as the premier commercial, industrial, agricultural and cultural inland city of New South Wales and indeed it is acknowledged by many to be the real heart of this great State. It has a population of about 40,000 people. The city water supply is all surface water, the majority of which comes from Chaffey Dam (62,000ML). Water is extracted via an intake on the Peel River about 50km downstream of the Dam. Tamworth also has a supplementary supply from Dungowan Dam (6,200ML).

NATIONAL LEARNING RESOURCES FOR THE WATER INDUSTRY Wayne Morling – Government Skills Australia
+Abstract
Access to training and assessment for water industry operations personnel continues to be problematic. With the introduction of national training packages, minimum industry performance standards have been developed. However, it remains difficult for industry to progress its personnel to desired levels of performance, in the absence of suitable training and assessment.

DENITRIFICATION PROBLEMS AFTER UPGRADE OF THE OLD BAR STP Lindsay Walsh – MidCoast Water
+Abstract
The Old Bar Sewerage Treatment Plant was commissioned in 1985 and upgraded 2004. The original plant had two 2000 EP intermittent aeration Pasveer channels with a catch pond of 2ML. Effluent held in two ex-filtration ponds and passed through dunes into the ocean. There were also two sludge lagoons of 700kL and two sludge holding beds. With the expected increase in population over the next 20 years, MidCoast Water decided the plant was in need of an upgrade to cope with this increase.

IMPLEMENTATION OF TEMPORARY WATER FILTRATION AT BRIGHT Rex Humphreys – North East Water
+Abstract
Bright is a sub-Alpine tourist town located in North East Victoria. The Bright water supply is directly taken from the Ovens River with Chlorine disinfection only. Historically, the water quality has met the Australian Drinking Water Guidelines turbidity standard, however since the 2003 and more recent 2006/07 bushfires, the water quality has declined, with sustained turbidity levels exceeding 5 NTU.
