Hi All,
Just wondering if anyone is using pressure diffentials in their design of dual reticulation systems (ie maintain a higher pressure in the potable main than recycled main) so as to minimise risk of cross contamination in the event of accidental cross connections. Im referring to large...
Hi all,
We've got a sewer pumping station where the high point is at the station itself and then it pumps downhill with several intermediate high points, then goes under a creek to the recieving sewer on the other side. Air Valves will be placed at hight points. There will be large amounts of...

Hi All,
If we have a water reservoir (say with a water level of 100m), then 2km of 300mm watermain to a pressure reducing valve, how is the 'maximum allowable pressure drop' across the valve calculated. Just to note that downstream of the Pressure Reducing Valve is a normal water reticulation...
Does anyone use (or know of) minimum velocity criteria when designing new potable water distribution systems to maintain water quality (ie water age).
Thanks in advance for any comments.
