Recovery of water--what does that mean??

[John T.]

When someone request that you recover the water does that mean that you have to pick it up or does it mean that you can keep it from pouring down the storm drains and in doing so letting the water evaporate??

I know recovering is the environmentally right thing to do but so is damming the water from going down the storm drains...but once again is that considered recovering??

[Paul Kassander]

Just keep it out of the drains, evaporation is a good thing, less to haul back for treatment.

Question & Answer

Thanks,

Larry,

Good to see you. In looking at the panel of experts, I would assume the seminar specifically would deal with TX policy as it relates to recovery vs. a national approach.

By just damning it and letting it evaporate, doesnt just the water evaporate and the chemicals and sludge that was cleaned off remain until the next rain?
I am getting so confused on what is right and what is not the more I look in to reclaiming. So far I have only done residential so all the water stayed on the property.

I'm mostly talking about cleaning with Hot or Cold water only. I'm with you thinking that if your using chemicals such as Bleach or a degreaser then you probably have to pick up that water to be compliant and not to leave it just do evaporate. But then again I'm not PWNA certified in this dep't yet so I'm not sure what the exact procedure is here. I will be looking to get PWNA certified in this area in the future so I can Market that along with my Wood Certification that I Market now.

If Robert Hinderliter wasn't so far away I would check that above class out to get more insight.

Evaporation is great, but unless it is piping hot outside, you will generate water faster than it can evaporate.
I do almost all my washing at night, so evaporation is not a good friend of mine.
Water does not always have to be recovered, it can be diverted as well. Just depends on your area, and what is in the water.
It used to be that as long as you kept it out of the storm drain ,the no problem, then came the solids issue after evap, and then the issues of what you might be putting down the sanitary. Does it ever end?

[Paul Kassander]

OTP you are correct it does notalways need to be recollected it varys by communities because of many factors. And you will almost always need to recollect some water, the key is to put your collecection point as far away as possible so you collect as little as necessary. You should always do a rins down at the end as well to clean up your runoff.

Interpretation of anything can go many ways. I would gladly rent you my recovery system , what is their meaning of 'recovery'? Taking the waste water and being able to reuse it is possible, without harm to your machine. BUT....what is the scenario?

Problem with putting it farther away is that unless you rinse that in between section, then you still have the solids issue. Rinsing all the way to the recovery can be very time consuming as well. I'd rather pick it up close, and not have to rinse any more than I need to.
In my experience, I use about the same amount of water either way, just save time by not rinsing areas that are not being paid for.

[Paul Kassander]

You can do some damming up close that settles out the solids and let the water run past and evaporate. There is still a little mor to rinse, but if your hauling capacity is light it can help.

The scenario well that would be the big mystery. What would one company consider acceptable for what the reclaiming should be..now that is the Question.

Thanks for the offer to rent your equipment. Its good to have friends in this industry

I have not hauled dirty water in a long time. I discharge onsite either to the sanitary or the landscape. I use to recycle water all the time, but it gets real tough on unloaders, especially K-7's. I have now switched to the ZK1, but have not run any recycled water thru it to know if they last longer than the other.

I am gearing up to recycle again, but will be doing the filters a bit different than before.
