Remember when... Well, I could make this a "period" piece or go on forever - like remember when it was cool to have a pager to keep in touch etc... Whoops, this is a water treatment blog, so I will stick with telling you that now, I am having fun reminiscing with my zero bleed customers .... “hey, remember when we used that solenoid bleed valve for solids control... and now it’s a paper weight on your desk!”
What we do know now however, is that simple math can be scary. If, for example, you were to take into account that you found that all of your cumulative leaks in your tower totaled one gallon per minute; that would be equivalent to over 1/2 million gallons a year. Now let’s say you have the following water cost totals - supply water and sewer respectively, @ $8.67 & $5.309 per thousand gallons. Now, you are looking at $7,347 in out-of-pocket expenses. WOW!... that's worth a great year-end employees’ BBQ with lots of distilled C2H5OH over some crushed cubes of DHMO.
All jesting aside, keeping an EYE ON LEAKS means saving your budget from going down the drain and at the same time doing something good for the environment.
Traditionally, when we treated towers on chemicals, the solids needed to be controlled; very closely, in some cases, or you would suffer the consequences of scale or corrosion - so you would need to bleed water from the cooling tower etc... Ironically, you would be amazed at how many chemically treated systems today are indeed bleeding but not from the bleed solenoid, but rather from leaks and calling it good, all in a day’s work.
Now, that our focus has shifted to water conservation and how we would prefer that no water be lost on a program like WCTI’s zero bleed, we find ourselves tightening bolts that have vibrated loose on the tower sides and basins, fixing drift problems, repairing basins that were creating permanent wet spots around the tower etc...
So, I highly recommend becoming your very own water loss police/detective and get out there and keep your EYES ON LEAKS.
