    192. Reticulated Water – Testing Regime


    Coliforms are used in operational monitoring of water distribution systems to indicate inadequate treatment, breakdowns in system integrity or the presence of biofilms.

    1. What are the current guideline levels used by Power and Water to indicate coliform contamination?

    2. On how many occasions during 2008, 2009 and 2010 did monitoring of the reticulated water system in Darwin and Palmerston indicate levels of coliforms above the guideline level?

    3. What were the locations of those above guideline results?

    4. What steps were taken to identify and address the above guideline results?


    1. The Australian Drinking Water Guidelines are utilised for monitoring microbiological water quality. These guidelines specify that at least 98% of samples collected from the reticulation system should be absent of Escherichia Coli (E. coli).

    2. None.

    3. There were no above guideline results.

    4. Steps taken to identify.
      The presence of E. coli in drinking water supply systems is determined by laboratory analysis of water samples. Across the reporting periods 2007-08, 2008-09 and 2009-10 approximately 2000 water samples were collected from the Darwin and Palmerston water supply distribution system. Samples are analysed at the Department of Resources Microbiological Laboratory in Darwin.
      Response to any above guideline results.
      No above guideline results have been identified. A positive result has been detected on three occasions from approximately 2000 samples: Hydrant at East Arm Port in May 2008 and March 2010, and Rapid Creek sample site in December 2008.
      A positive E. coli detection in any sample triggers an immediate review of all bacteriological results from other sites sampled on the same day. Based upon available evidence a response would be formulated and executed by operational personnel. The circumstances and the operational response are communicated to an established contact officer in the Department of Health and Families.
      Such a response may involve a combination of actions including site inspection, re-sampling, field confirmation of chlorine residuals, manual dosing of chlorine and flushing of water mains.

    195. Rehabilitation Services Provision at New Prison


    1. What entities are going to provide the compulsory rehabilitation and treatment services proposed as part of the initiatives announced to complement the new prison precinct at Holtze?

    2. Will these services be situated within the prison precinct and, if not, where will they be situated?
    Home Detention Verification by Voice Recognition:

    3. Voice recognition for identification of individuals is proposed for home detention. What evidence is there that supports the use of voice recognition technology?

    4. How will that process for determining compliance with detention orders be able to be used in remote locations?


    Service providers for external training and rehabilitation programs run at the new Darwin prison precinct will be determined through a standard government procurement process.
      The government is also constructing and/or funding 45 rehabilitation and supported accommodation beds across Alice Springs, Darwin and Katherine. These beds will be managed by non-government organisations, to be determined through a standard government procurement process.

      Home Detention Verification by Voice Recognition:

      The voice recognition system will be an additional monitoring option for offenders and parolees serving their sentence or parole period.

      Voice recognition is currently used, and has proved successful, in both South Australia and New Zealand as a means of monitoring offenders’ compliance with court orders. It operates through designated land lines or satellite phones in set locations, such as a police station, and can include Internet interface, such as a web camera. Voice recognition and other electronic monitoring equipment provide a secure monitoring system, greatly improving procedures in areas where face-to-face checks can be difficult.

      196. Speed Cameras, Guns and Monitoring Equipment


      1. In the 2009-10 financial year, how many motorists were booked for speeding offences in the Northern Territory?

      4. Can you provide percentage breakdowns of the speeds at which motorists were booked in 10 km/h increments?

      5. How much revenue was raised from speeding fines in the 2009-10 financial year and what percentage of that was from fixed and hand-held speed cameras?

      6. How much above the speed limit will a fine be activated?

      7. As at 1 October 2010, how many hand-held speed cameras are in service?

      8. As at 1 October 2010, how many fixed cameras are in service?
