above ground holding tank

We have one at our seasonal - over the last 5 seasons we go 3-4 dumps per season. Never gone more than 4. We're there every weekend plus at least one full week. We do military showers and are careful, but not stingy!

First thing that occurs to me is to wonder how fast that puppy will fill up. I've been involved in some sewer planning projects, and average water use in a residential setting is assumed to be 125 gallons per person per day! Most of which goes down the drain, of course.

I s'pose RV use might be a little lower than that, depending on appliances etc, but still- at $20.00 a pump it won't take long to make your sticks-n-bricks sewer bill look like chump change.

I think you'll find that RV use, particularly when not on full hookups, is considerable less than that. My wife and I can easily go a week before filling our 70 gallon total waste tank capacity without even trying hard, and without using public facilities for showers or anything else.

I was thinking that the O.P. would have a water hookup, too, at the site with the tank.

Folks tend to use more water when it keeps coming out of the tap!

Well call me Green also, I shower every day and DW and I can go a week on internal storage easy. Yes I has my hands during the day, use the RV for all restroom and showers, and washing dishes, Pots and Pans.

I will add that many of the coastal Oregon State parks, have limited or no full hookups, you learn to conserve.

could you adapt this as an indicator? it has a female hose end on it.

When you design for a rv park you have people like me the only reason to stay would be to dump my tanks. Also some people can be very waste full so yo have allow for that.
I don't think someone is going to drive a big truck out to pump one tank for 20$ so the must do it on certain days?

We must be very different. Three adults, no washing machine, use 60 gallons of water every 4 days, without conservation. We do take "Navy" showers.

That works out to 15 GPD? That is 1/10th of what you state is "average normal."

I don't design waste systems so I may be missing something.

There ya go- that's a pump every two to three days. (The O.P. says it's a three hundred gallon tank, at $20.00 a pump). That's $200.00 a month if you conserve.

For comparison purposes, the typical monthly rate for sewer in Seattle, Washington is a little over fifty dollars a month. Link to rate page

He didn't say he's living there full time...

I am a seasonal and about half the campers in our park use them. We were allowed to dig a small pit to put them in, all sand in our park so this was easy to do, they cannot be buried the top must remain exposed. There is a float inside that trips a flag like on a fishing tip up when it is near full. I am on my third year of using mine, me and my handicapped brother, generally have it pumped 4 times a season, May-Oct.

That GPD average use is predicated on 'holding tanks being dumped?

No average RVr is using 100-150 gpd.
