5 The Twinning Project Water PNG and Hunter Water have a twinning arrangement supported by the Asian Development Bank (ADB). An ADB utility twinning agreement facilitated specialist staff being available to assist Water PNG.

6 Our shared goals Water PNG desires to learn from the experience of Hunter Water and seeks their assistance to accomplish measurable improvement in its operational, technical and management performance Hunter Water is keen to share their experience and is willing to assist Water PNG

7 Twinning Focus Areas The project has four main focus areas 1. Reduction of the currently high level of nonrevenue water 2. Water quality 3. Lae masterplan 4. Asset Management.

8 Non-Revenue Water (Lus Wara) recognized to be of major concern for several decades

9 Project Aims Determine the current level of non-revenue water Complete a water balance using international methodology and terminology Identify the major sources of loss Develop an action plan to reduce losses to an economic level

10 How big do we think the problem is? Non-revenue water estimated to be 30% of supply A huge loss of revenue Potential high demand on sources if loss due to leaks

11 Non Revenue Water As part of the twinning process, a specialist from Hunter Water spent a week in Lae teaching local staff how to prepare a water balance.

12 Are all of our sales metered?

13 Are you sure there s a meter here?

16 Losses were greater than we thought The water balance established that the baseline estimate for non-revenue water in Lae was 46%of water produced for The Infrastructure Leakage Index (ILI) was calculated to be 31.1.

19 Action Plan A targeted action plan was developed to deal with the most critical issues in the shortest time. Major initiatives were to improve metering, particularly that of major customers, and reduce illegal connections in settlement areas.

20 Are our meters in good condition?

21 What are the security issues?

22 Focus Areas 1. Accuracy of input flowmeters 2. Failed customer meters 3. Management of large meters 4. Zone meters out of service 5. Unmetered customers

23 Calibration of input flowmeters

24 Replacement of failed meters

25 Repair of zone meters

26 Results? For Water PNG, the gains have been quick and significant in terms of the extra capabilities of its staff and the increasing amount of extra revenue received each month from now on.

27 Revenue Increase Three months later, the Lae branch of Water PNG collected the highest ever amount of revenue ever achieved. Average monthly revenue this year has increased from K1.8M to K2.6M In July and August the average revenue has increased to K3.4M

28 Ongoing Monitoring Local staff had the capability to track progress on the decrease in nonrevenue water to 35% with their new water balance model.

29 Identification of other issues System performance Reservoirs not filling Pumps of their curves Water System Model Wastewater Treatment Plant upgrade Use of telemetry

30 Policy development Hunter Water has also assisted with the development of policies for: Meter installation Meter replacement Trade waste Backflow prevention Water quality testing

31 Why has twinning worked? The availability of experienced specialist staff (all have more than 25 years industry experience) The use of a structured, internationally-recognised model for evaluating nonrevenue water. Ongoing relationships partners, not just advisors

32 Tenkyu!
