    To all who might have input. I've gotten word as of last night that I am to sit in on a panel today to discuss the very real possibility of haveing effluent water used on our golf course. Very short notice for me to do much research on the topic, but its this afternoon. A little background already.

    Located in western north dakota on very sodic soils with very sodic water. We currently use a local river source to fill ponds and in turn treat that water prior to it entering our irrigation system with various chemicals in an injection pump, as well as burning a sulfurous generator to neutralize carbs and bicarbs and balance the pH. We've been able to do an okay job over the past years, and I don't know how the blending or full use of effluent water will alter our chemistry in the short and long term. Obviously, We'll need to do some testing on the final product, as well as blends of river and grey water to find an optimal level.

    So my questions are:
    how does effluent water change your fertility programs?
    How does it affect the pH (usually basic correct), carbonate and bicarbonates, as well as sodium levels?
    Is there an EPA standard to "guestimate" what we'll be looking at for a final product?

    Any other detrimental, or positive effects to add would be welcomed. Thanks to any and all that apply.

    Kyle,

    We've been on partial reuse now for about two years. By partial I mean 100% about 5 nights a week, then back to our wells the other two. Attached is a guideline I got from PACE Turf. It's a guideline, and I'm sure is different in your location. But, by using this as a base, I've realized that we get some really good effluent, comparatively speaking. See below for answers to your questions.

    So my questions are:
    how does effluent water change your fertility programs?Not much. At least not on our sandy soil Yours may be different. We calculated that the 70,000,000 gals per year we apply equates to a little over .25#N/m at the 10ppm Nitrate levels they keep the water. Our plant was going through the denitrification process and trying to bring that number closer to a 4. We worked with them and explained our needs, and now they keep it higher, around a 10-12ppm.
    How does it affect the pH (usually basic correct), carbonate and bicarbonates, as well as sodium levels?Our effluent pH is around 7.2. Not bad. Our ground water is a 7.6. So not much of a change. Also, our bicarbonate level was very low. we do still apply Calcium to flush on a monthly basis, as I see no negative effect of doing this otherwise. Our sodium is still good in the water we receive, therefor no need for additional flushing.
    Is there an EPA standard to "guestimate" what we'll be looking at for a final product? Take a look at the attachment.

    Any other detrimental, or positive effects to add would be welcomed. Get a contract stating how much water you will need to take on a daily basis, and what they will be required to send you. Of course, as long as you have a backup, this may not be an issue. I'd also lock in a price. We pay $.08/1,000 gallons. Others in our area are free, up to $.40/1,000.

    Thanks to any and all that apply.


    I also hired a guy that helped me better understand this stuff. Was well worth what we paid him. I can pass on his number if you would like.

    Great Info Andy.....We at present are doing a 15 mill upgrade to our water treatment facility. The City is looking into the possibilities of effluent here. This will give me some info to give the commission. Be a good topic for a Webinar. Sure it's been done, but would be a good refresher too.

    In discussing effluent water use I would go back to my work with effluent water and seashore paspalum turf in Naples Florida. Its saltwater tolerance and having no issues with the ph levels sometimes fought in effluent water make it a great choice. However not a northern turfgrass delete it from helping you out! I would imagine in your case it will be the ability to treat the water prior to your use, or potentially the rainfall and drainage quantity and quality you get to resolve build up of poor chemistry in your soils.
