Inspection and control of the water supply network

Problem velikog gubitka na vodovodnoj mreži se pojavio u firmi “Eurometal”iz Teslića pri čemu smo kontaktirani da izvršimo pregled mreže i ustanovima mjesto puknuća. Izvršili smo prethodno vizuelni pregled i obilazak kruga fabrike, a s obziorm da nije postojala nikakva katastarska podloga sa ucrtanim položajem cjevovoda, bilo je potrebno isto istražiti. Takođe na osnovu dostupnih informacije koje su bile nepotpune bilo je potrebno sagledati i izvršiti provjeru za sve objekte, jer je od prvobitnog stanja fabričkog kruga izvršena podjela na dva odvojena privredna subjekta, sa samostalnim priključcima na vodovodnu mrežu.

After the preparations and assessment of the scope of work, the routing of pipelines was carried out with the checking of power supply arms for business facilities, i.e. production halls. Having determined the position of the pipeline, an inspection of the internal sanitary and hydrant installation was carried out. The outer ring of the hydrant network around the facilities around the factory was also inspected, and listening to the network revealed an approximate section on the outer hydrant part, where there was a suspicion of failure.

Testing and leakage location

Using the correlation method, the area where the defect was located based on the results of measurements and tests was reduced. A more detailed detection revealed noise on the water supply network of very low intensity, due to the very configuration of the terrain and soil, which is gravelly and absorbs sounds, as well as the material of the PVC pipe on which the failure occurred. After the fault was located, the pipeline was dug up and the fault removed.

According to the results of the water meter readings, the average consumption of this business entity in the period before the failure occurred was about 4.6 m33With the occurrence of the malfunction, and based on the reading of the water meter, the consumption increased many times and on a daily basis in 24 hours it amounted to about 83.3 m3.

By repairing the defect, the daily consumption returned to the normal level of about 3.5 m3.

LEAK DETECTION ON THE HYDRANT NETWORK

At the invitation of the managers from the commercial service of the company of the graphic trade company Atlantik bb Banja Luka, we performed an inspection and review of the water supply network within the company.

The control determined the existence of a fault in the hydrant water supply network with a significant loss.

After tracing the direction of the pipeline, we performed a test with an acoustic sound detector-geophone.

On that occasion, the fault was located in front of the entrance to the office building, which was removed the next day by engaging the necessary mechanization and human resources.

LOCATION OF WATER LEAK ON THE INSTALLATION

Due to the problem of increased consumption and enormous amounts of water that flowed invisibly, we received a call and a request from the management of VAMAL GROUP from Trn in the municipality of Laktasi. Detekcija kvara

We approached the visual inspection and control of internal installations with the manipulation of individual arms on the same.

Since the client could not provide us with the necessary technical documentation of the position of the installations outside and inside the office building, we had difficulties in determining the route. The installation is PE profile 3/4 "and it is very difficult to determine its position more precisely. Istraživanje geofonom

According to experience and with additional equipment, we were able to approximately determine the position of the installation, and performed a fault test with an acoustic sound detector - geophone.

After we precisely located the fault at the entrance to the business hall, and after eliminating the fault, the control determined that there are no more invisible losses on the plumbing installation.

At the request of the management of the County Hospital “Dr. Mihovil Sučić ”Livno and the signed Agreement, by“ NMAqua ”s.p. Banja Luka, during April and May, fault detection works and tracing of the water supply installation within the hospital were performed. Due to the occurrence of enormous consumption, which in just seven days amounted to about 1413m³ or 202m³ / day, unlike the previous period when the average monthly consumption ranged between 760m³ and 820m³, we undertook under the Contract to detect failures and reduce consumption to the previous period. .

Locating the location of the hospital installation

Considering that during the preparation for the execution of works, we received information about the non-existence of a precisely located position of the installation, it was necessary to do that part of the work as well.

In order to detect the uncontrolled leakage of water on the hospital's water supply network as accurately as possible, we first traced its position with precise location of certain points via GPS devices.

After the exact position of the outer ring installations, as well as each position of the place where the installation entered the cliff, as well as the position of the part of the inner installations that was available for tracing, the loss was detected. After a detailed and extensive control, listening and testing of the water supply network with an acoustic sound detector - geophone, a fault was located in front of the hospital, which was located at the fork of the installation around the building.

Significant savings after fault repair

Due to the urgency and reduction of losses, and therefore financial costs, employees of the technical service of the Provincial Hospital "Dr. Mihovil Sučić ”Livno, very quickly approached the solution of the mentioned problem and excavation and elimination of the located fault.

By monitoring the continuous consumption after the elimination of the fault, it is evident that the situation in the supply of the hospital has normalized and the consumption has decreased compared to the previous period to an average of about 720m³/month. It is also important to note that according to the technical service, the pressure on the hospital's water supply network increased by an average of 1.5 bar, which greatly reduced the operation of pressure pumps for certain devices on the third floor of the hospital, which certainly reduces the cost of electricity. In order to complete the work on the works that were agreed in the contract with the County Hospital "Dr. Mihovil Sučić ”Livno, the GIS database was formed with its integration on the WEB platform.

LOW-INTENSITY LEAKAGE

As long-term associates, we received an invitation from the management of the company "Peštan" to help them solve problems in the plumbing installation-hydrant network.

 

The leak was very difficult to notice, because the intensity of water leakage is very low. At the same time, the pressures in this part of the city's water supply network oscillate a lot, which makes it difficult to locate the place of water loss.

As this is a water supply network within the company, which is known to us from previous research, the job of locating a fault on the hydrant network has been made easier, considering the time required.

The correlation method narrowed the circle to the part of the hydrant network around the last building-hall to the north.

As a small part of the network remained, a visual inspection of the terrain around the building, which is in the same range - earth and asphalt surface, was performed. There were no visible signs of loss on the ground, but an inspection of the manholes with plumbing fittings revealed a fault in the manhole at the Ø80 mm pipe connection fitting.

By measuring with an ultrasonic flow meter on the part of the network that remained for the loss investigation, and which was isolated, approximately the same amount of water was determined on the basis of the issued bill for the consumed water for a month.

Gas station leak detection

by with No Comment informacije

For the needs of the contractor on the newly built facility of the gas station "Hifa petrol" in the settlement of Lazarevo in Banja Luka, it was necessary to perform a fault test on the installation from the fuel tank to the filling point.

Namely, after putting into operation, a drop in pressure was noticed on that part of the installation from the pump in the tank to the place where the automatic refueling machine is located. The length of the mentioned control route was about 30 meters.

Since the pressures are very low during the operation of the pump, for a more precise location of the fuel leak, the pressure was raised by the air compressor.

With such conditions where a pressure of about 4.5 bar was reached, the fault location was successfully located.

After the excavation, a leak was found at the marked place and repairs were made.
