Our specialization is water leak detection

The water leakage in water pipes
Data about leakages are based on HONEYWELL Co.:

Monitoring
Wodoserwis offers controlling systems in waterworks especially in water supply systems to reduce water leakages.

The new a data logger specially designed for the needs of water suppliers. The logger is battery powered which lasts for 5 years even with integrated GSM/GPRS module. This unit is available in several configurations with internal sensors and various input channels.
Wireless programming and read out: Yesterday was the time to connect each logger with a cable to program or to read data. In combination with the PC radio interface USB-E-box one can simply program several loggers one by one via radio. The read out process works the same if you use the Reader Box. Simply go near by the logger (radio range up to 20m and more) and collect all data stored in the internal memory of the logger. Transfer the data later to your PC and do your analysis.
Recording: How ever your recording interval should be: you simply program the loggers for your special needs. From 1 sec. up to 31 days an interval can be chosen. The huge internal memory of the logger saves data up to 28 years and if this is not enough one can simply upgrade the memory with standard SD/MMC cards.
Sensors: This unit is available with integrated pressure sensors or simply as a “regular” data logger. All 0-5V or 0-20 mA sensors can be attached and the data can be logged. The accuracy is certainly ± 0.1%.
Telemetry data logger: As a special version the device comes with an integrated quad-band GSM/GPRS modem to transmit data over a long distance. Data are provided via FTP to easily integrate the data into existing telemetry systems.
Alarming: Each channel has individual alarm thresholds. Once this threshold is reached the logger sends a SMS or message to the telemetry system.

The water distribution networks and sewage systems pinpointing
We localize metal networks at the depth of 6,0 m and metal street furniture - 0,5 m underground covered with soil or concrete.
If there are pipes crossings our localization will be at the depth of 6,0 metres.

The recommended standards for water consumption

standards water consumptions

In Poland obligatory standards water consumptions are defined by the Polish Government in official documentary “Rozporzadzenie Ministra Infrastruktury z dnia 14 stycznia 2002 r. w sprawie okreslenia przecietnych norm zuzycia wody (Dziennik Ustaw nr 8 z dnia 31 stycznia 2002 r. - Poz. 70)”.

However, there are another detailed recommended standard the water consumptions based on technical documentary or operator’s manual etc. as given below.

Another detailed, recommended standards water consumption

Air Conditioning

Air Conditioner type KT 2.1
Condenser cooled water temperature: 12 ^o C, water capacity: 400 l/h, inside diameter d= 15 mm.
(based on air conditioner KT 2.1 documentary – Germany, VEB Maschinen und Apparatebau Schkeuditz)
Another type KT:
KT 4: 350 l/h
KT 4.1: 420 l/h

Type CAS (Clivet - Italy), ex: CAS 51: 1 800 l/h
Type K 3 300: 200 l/h

Laboratories

The water consumption in laboratories (data based on installation documentary):
a polish water re-distiller type REL 5 (capacity 5 l/h) - consumption 150 l/h
a polish water distiller type DEM 10 (capacity 10 l/h) - consumption 85 l/h, type DEM 5 (capacity 5 l/h) - consumption 42 l/h

Bakeries

The water intake only for dough production (the water intake as a raw material without sewage for sewage system)
1. The dough production:
100 kgs flour needs 50 l water, it means that 1 kg the flour needs 0,5 l water
2. Steam production in baking oven:
Medium size baking oven needs 870 l water per day
3. Water consumption for steam in steam pot:
1 steam pot needs 1 000 ls the water per month
(Information comes from bakery’s owner in Krakow city consuming 98 600 kilograms of flour a month. Eight tenth of this flour is used for bread and the rest for sweet croissants and doughnuts).
According to “Rozporzadzenie Ministra Infrastruktury z dnia 14 stycznia 2002 r. w sprawie okreslenia przecietnych norm zuzycia wody (Dziennik Ustaw nr 8 z dnia 31 stycznia 2002 r. - Poz. 70)”, all in all the bakery needs: 2,0 m3 the water for 1000 kg bread, it means that 1 kg bread needs 2 l the water.

Canteens

(based on the Polish book: "Wyposazenie stolowek w zakladach przemyslowych" - author: Z. Mirski)

the water for handy dishes washing: 7,5 l for 1 meal
the water for dinner: 30 l/dinner (the first course and main course altogether)
the water for worker regenerative meal: at the table - 15 l/meal, take away meal - 7,5 l/meal.

Hydrants

External hydrants with nominal diameter DN 80 should be provided for water pipe network. Nominal capacity of external hydrants DN 80, with nominal pressure 0,2 MPa (2 bar) on the valve, should be at least 10 dm³/s.
Polish governmental document: an ordinance of Minister of Interior and Administration of 16 June 2003 "on water supply and fire access road for fire protection" (OJ No 121, item 1139)
