many thanks, i appreciate ur feedback ...

Greeting im building sewercad model for a network and im facing minimum velocity problem at the beginning of the line .. the loads are low at the starting point this is my first model can anyone help me many thanks...

greetings i have a water network, where i know the demand at each point and the layout of the network... the network should be feed using pumps from reservoir,,, im trying to figure out how to know what is the total flow and total head which i should chose the pump based on. im using watercad

hi all, i have recived a water network model, this model consists of UPVC pipes 200 mm, when i run the model through watercad i faced some problems mainly that velocity is going higher than 1.5 m/s and lower than .3 m/s and start increasing the pipes diameter but this did notwork to decrease...

thanks for all your notes were very helpful thanks

thanks alot but what i was lookg for is printing the files properties in the folder best

I’m looking for excel sheet that work as directory printer, to print the all the file name, type and other properties in an excel sheet Best regards,

Thanks unclesyd for your advice, did you use the helium before, what is your experience in that? Do you know any website about leak detection using helium for the portable water?? Can you please send me some of these, I will highly appreciate.

thanks alot for you sport, me two new to this technology, i have found something about Hydrogen gas detection method, (( Identifies leak position by detecting the location of hydrogen gas which has been introduced into the water supply. The hydrogen gas (carried in 93% nitrogen) rises to the...

Yes Helium for water, why you are shocked??? I have seen the test done in two areas and the results were excellent, but the main problem (in my opinion) that you will find micro leak and if u don't have enough budget you will have problem. But in case that your network is new and u have enough...

Hi I think we have some illegal use in this area; also the tank that feeds the area is getting empty very fast.

Hi We are planning to use this technology and company will help us in this, the water pipes dose not need to be dewatered, the helium will be pumped with water in the same pressure. We have sounding equip. but the problem is in the technicians, it was very difficult to them to distinguish the...

i will check the flow rate... regarding the mineral deposit , i dont think we have becuse we have a low TDS.

Thank you all. What we are working on is portable water, it distribute water for the whole state, with dimension range from 600mm to 63 mm with more than 700KM. we are planning to test the pipes while it is full of water ( while it is operated ) some of the pipes are more than 10yrs old... the...

Hi I mean geographic information System (GIS). Value engineering is eliminating the unnecessary cost without reducing the quality, that what I understand value engineering. Regards,
