7. Backflow What is backflow? When does contamination occur? What is cross-connection? What happens when a cross connection occurs?

8. Backflow Incidents “Yellow gushy stuff” coming out of some taps in Maryland turns out to be a powerful and highly toxic herbicide from an agricultural facility. Propane gas flowing into a Connecticut water main came from a storage tank which causes a washing machine to explode. “Rusty” water coming out of a Michigan hospital’s drinking fountain turns out to be blood from a nearby autopsy room.

9. Backflow Incidents HUNDREDS of western Sydney residents have became ill after drinking recycled water. Recycled water was mistakenly pumped through drinking water pipes. 82 homes in four streets in Glenwood were cross- connected, allegedly after a plumbing mistake in a house under construction....it was believed a plumber had accidentally crossed the pipes while he connected them.

10. Backflow in Regional Victoria

11. Water Corporations in Regional Victoria ● Barwon ● Central Highlands ● Coliban ● East Gippsland ●Gippsland ● Goulburn Valley ● Goulburn-Murray (W) ● Grampians Wimmera Mallee (W) ● Lower Murray● North East● South Gippsland ● Southern Rural (W) ● Wannon ● Western ●Westernport

12. Regulations Containment protection is regulated in Victoria through: Water (Estimation and Sewerage) Regulations 2014, Part 2 (11) Individual Water Corporation Policies Individual Water Corporation Guidelines AS/NZS 3500 2003 Part 1 water supply

13. Backflow in Regional Victoria Most Water Corporations are doing something about backflow including: Policies or guidelines Separate application for installation Ongoing agreements for the management & maintenance Programs to retro fit devices to existing properties. Fees and charges

14. In 2010-2011 a working group was established in Victoria with representatives from a number of the Water Corporations to workshop a common set of Guidelines across Victoria. In June 2011 the “Backflow Prevention Containment Guidelines” were established

17. Regional Water Corporations think that it is important to have Guidelines in order to protect their water quality. 50% with no Agreements A retro fit or backlog program. Applications are important Fees Backflow in Regional Victoria

18. Water Corporation appear to have their own risk based assessment approach Backflow incidents are thought to generally occur in industrial type buildings A significant proportion of incidents in Australia involves domestic type plumbing A need for education and enforcement of existing regulations

19. Overcoming the Challenges

20. Overcoming the challenges The Past No adequately trained staff in backflow Only a handful of Commercial, Industrial or irrigation type connections Rural setting with rural attitudes

21. The Past 20 years ago Backflow Prevention Devices were being fitted Larger customers and councils began to install and test their devices Plumbers tested the devices and sent in test certificates No further action

22. The Beginning A new start The beginnings of a BP program Accessed all of our filing systems to find any test certificates, we found 266 Our current Customer Relationship Management (CRM) system did not allow for a BP program

23. We reviewed how other Regional Water Corporations dealt with BP An installation & enforcement software program from a neighbouring Water Corporation was chosen Reviewed our CRM to find all non –residential properties 420 properties were separated into High, Medium & Low risks The Beginning

24. Considerations to Develop a BP Program Implications & considerations for business changes Costs Rural properties & farmers Internal budgets & resourcing Justification to business

25. BP Program in Development We now have a list of potential properties and photographs to review

31. The Future is Implementation Western Water is now in the process of developing and implementing a backflow prevention program for all new and existing properties We need to consider the learnings from implemented programs at other Water Corporations? Training staff Education our customers and plumbers

32. The Future is Implementation There is no future in not doing anything If a property has no backflow prevention device at the boundary It can result in a direct threat to the community’s health
