Our New Water Source

I'm sure almost all of our membership knows that we are now accepting reclaimed water from the Pillsbury plant across the river. The main comment that I get from our golfers is something along the lines of, you won't have any problems putting out water now. In some respects this is true, but using reclaimed water has its draw backs too.
Reclaimed water sources typically have elements in it at unwanted levels. Typically the problem sources are pH, Bicarbonates, and Sodium. They are present in natural water sources also, but usually at an acceptable level. I have some numbers to show acceptable levels, our previous water source and our new water source below.
Acceptable Levels
pH- 6.5-7.0
Bicarbonate- 0-111 ppm
Sodium- 0-70 ppm
Calcium- greater than Sodium
Old Source
pH- 7.2
Bicarbonate- 144 ppm
Sodium - 13 ppm
Calcium - 42 ppm
New Source
pH- 7.5
Bicarbonate- 451.4 ppm
Sodium- 259.17 ppm
Calcium- 50.91 ppm
As you can see the numbers drastically increased in every category with the exception of Calcium. Unfortunately Calcium is the only part of that list that we want to be really high. What this means is that we will have to make more chemical applications and Calcium applications to combat the higher numbers of pH, Bicarbonate and Sodium.
So, yes we will be able to put out more water, and get water to areas on the course that haven't seen anything but rainfall in a long time. At the same time we have to monitor the levels of water that we put out. Sometimes too much of a good thing can turn bad. Hopefully as we can get more of our irrigation system operational, we will be able to get ample amounts of water to the turf within the scope of the irrigation system.
Also, we were able to get some national exposure for the club with the reclaimed water project. Golf Course Industry Magazine used our project as a case study in water management practices in its September 2009 issue. Here is the link for anyone who is interested in reading it.
