Control flow measurement and consumption analysis
Based on previously successful cooperation in metering, analysis of the state of the water supply network and fault detection on the same, we were invited by the management of the Business Zone to perform measurements and analysis of consumption in the water supply system within the "Business Zone".
After monitoring the water consumption on the water supply system "Business Zone", the difference in consumption was recorded by reading the main water meter and water meters of consumers who are leased business premises, as well as owned, and who are supplied through it.
According to the data, the difference in the monitoring of consumption by the technical service "Business Zone" is about 100m³ on a monthly basis for about 60 internal consumers.
Flow measurement and consumption comparison
Due to all the above, the engaged team "NMAqua" s.p. is on 05.01.2020. year, the installation of an ultrasonic flow meter was performed. The flow meter is programmed to operate and store data at an interval of 1 min and a time period of 72 hours, in order to obtain the most accurate state of the network.
Due to the impossibility of installing a flow meter in the water meter shaft in which the water meter is installed, through which the complete "Business Zone" is supplied with water, an alternative measuring point has been determined where quality flow control and measurement can be performed, which is in front of the water meter
The main goal was to record the condition of the network, ie to measure the flow at night, in order to eliminate any possibility of any consumption on the installations.
By analyzing the obtained results and flow diagrams, we recorded at that time that there is no water consumption at night in the water supply network, as well as in installations, which indicates a difference in reading the main water meter and total consumption of user water meters, as well as inaccuracies of old meters.
Occurrence and detection of fault location
However, after a short time, there was a problem with an average difference on a daily basis of about 35m³, which indicated abnormal consumption or the existence of uncontrolled discharge.
By engaging the NMQau team, measurements were performed on the arms, with the manipulation of individual parts, as well as the consumers themselves. Based on the data, a malfunction was found on the part of the water supply network on the PEHD Ø110mm pipeline which is supplied to Nova banka.
An acoustic sound detector test determined the exact location of the fault on the asphalted part of the bank's parking lot
An excavation was carried out, during which a fault was confirmed at the pipe joint at the mentioned location.
