1. INTRODUCTION

• Water Utility of Istria, Buzet (WUI) provides drinking water supply service inmore then 60% of the area within the County of Istria

• Thanks to the DRINKADRIA Project, the WUI has implemented the Pilot Project -"Control Water Meters for More Water”

• The aim of the project "Control Water Meters for More Water”, is to identifyleakage and pipe breaks within the WUI water supply system, which willultimately result in decrease of the water losses.

• The activities which have been identified in this project include the analysis ofthe present WSS on the consumption control locations placed in DistrictMetered Areas (DMA) - the control water meters, the activities connected tothe tendering procedures, equipment commissioning, operation of the AMRcontrol 2.0., employees’ training and finally, all the activities connected to theproject results

2. SUPERVISORY CONTROL AND DATA AQUISITION (SCADA)

• We have been implementing and using the SCADA for many years• The SCADA consists of the Dispatching Centre placed in the Buzet and three

sub-centres: Sveti Ivan, Gradole and Butoniga• SCADA main tasks:

- Efficient monitoring and management of the processes of water treatmentproduction and distribution, from its source to the final consumer;

- Secure availability of water - prevention of large disturbances and breaks inwater supply;

- Secure effectiveness of the supply system – coordination between the plantand production process;

- Savings’ plan – minimising of the cost while keeping a high level of watersupply.

3. PARAMETARS FOR THE REDUCTION OF WATER LOSSES

• Monitored parametres:

- Daily consumption (24 hours);- Consumption the day before (48 hours);- Comparison (over, under - realized in %) for the last two days;- Minimal night consumption;- Consumption within the DMA (without the consumers);

• The data gathered via this system will be utilized for the hydraulic (numericalmodelling) as well as for the improvements and the construction of the watersupply network in the future (e.g. reconstruction works and building of newbranches)


4. NEW PROCEDURES

We have applied an operational instruction:

• Operational Instruction for Early Breakages/Leakages Detection within the Water Supply System by following the AMR control 2.0 application

- available to the Management, the Managers, distribution officials, system analysts in the Technical Department, foremen, dispatchers and the officials in charge of losses detection in the Operational Units

• Procedure for Breakage/Leakage Repairs list evidence assistance- The Application is reviewed daily by the officials assigned the task and, if

necessary, the system analyst and the production and distribution official from the Technical Department


5. IMPLEMENTED EQUIPMENT

• The new equipment enables:

- Accurate water distribution measurements, which present the primary module of a supply network management and thus create a basis for a safe water supply system, water balance and efficient picture of losses

- Reliable data acquisition from each of the control locations for the possibility of remote diagnostics and further data analysis in the control center

- Reliable, simple and up-to-date data analysis from the control locations for an efficient comparison of controlled measurements within water distribution, efficient management of losses and efficient adjustments of production and distribution of water to the real water consumption



• Arad Octave Ultrasonic Water Meters with DRINKADRIA labels



• Aplisens - pressure meter PCE – 28



• Inventia MT – 713 HC – logger



• Software AMR control 2.0.



• Software AMR control 2.0.


6. BENIFITS

• Improved water distribution surveillance within zones

• Following possible losses in the network according to the quantity of lost water

• Following possible losses according to night consumption

• Improved measurement accuracy

• Documenting

• Data comparison

• Graphic layout of all data

• Water supply system pressure monitoring

• Displayed battery status and signal strength


7. DIFFILCUTIES

• Document preparation

• Calls for tendering

• Appeal to the Decision and Documentation

• Water meter delivery

• Short deadline (105 days) of System of Remote Reading implementation

• Continuous problems with the mobile connection and the signal for water meter readings being sent to AMR CONTROL 2.0

• Scale


8. REACHED GOALS

• Monitoring the daily and night flow (consumption) of water in the distributionsystem

• Faster responses to failures

• 129 DMA on AMR CONTROL 2.0. application

• Modernization of the existing water supply system

• Key parameters for future surveillance were defined

• The process of system surveillance and leakage repairs was redefined

• Application for informing and evidence of leakage repairs agreed and launched

• Three-month report period on activities of noted and repairedbreakages/leakages was defined.


9. CONCLUSION

• Work on the Drinkadria project still is a great challenge. Nevertheless, thehardest part of work has been completed.

• Future steps:- Updating of the existing GIS base (pipes position, types of pipes and the

diameters)- Zoning: (129 zones) division to smaller zones according to implemented

water meters- Introducing the management of losses according to IWA methodology

or the ILI indicator- Analysis of leakage- Pressure adjustments in the critical zones (according to ILI indicators)
