We are finally having plans drawn up for the new house to be built on our property where my pond is at. The house will be built on top of the hill, above the pond. I don't know if I'll have a choice, but if I do, what would you do? Would you place your septic system on the side of the hill the pond is on so some of the water might work it's way down to the pond and help keep it full, or would you put it on the other side of the hill to try and keep the water from it away from the pond. It would probably be about 100' from the pond if I put it on the same side as the pond.
I plan to tell them to direct as much as they can (as long as it don't cost to much ) of any ground run off, roof drains and such towards the pond.
Thanks for any input.

other side.

If the field is 100' away from the pond, and requires a perimeter drain, then it might do some good on the same side as the pond. The perimeter drain could them be directed toward the pond since it should only contain clean water. Be sure to follow local codes though.

I would err on the side of caution. While the impact should be limited, I would prefer that no water could go to the fish to live in that I wouldn’t drink.

I am a MO state certified installer of onsite systems, it depends a lot on what kind of system you are looking at, they do a lot of lagoons in this area because of the heavy soils, I wouldn't put one of those on the same side as a pond because they do have a small amount of discharge, although it should dissipate before it would run 100 ft to the pond, but in a rain event some could get washed into your pond, also you wouldn't want it in the view looking at your pond, any other system shouldn't have any discharge to have any effect at all on your pond or the view of it as long as its working properly, on the same note it wouldn't have any benefit pro or con to your pond. if it was to fail I wouldn't want it failing into my pond, if for no other reason then the effluent is usually extremely high in nitrogen which will create a ton of water problems with weeds and such.

That's why I said other side.

Even if it didn't fail, would the water that leaves the septic field be higher in nutrients than say surface runoff water?

If its not failing, no septic water leaves the septic field.

So, where does the water go? The field is the leach bed, correct? Or is it a mound system?

Thanks guys? It would probably be a drip system, is what I was told.

Never heard of a drip septic till now: https://civilgang.com/drip-septic-systems/

Yipes, that is costly.

Pressure drip onsite waste systems, I put them in everyday, been working on one today actually. got one in my front yard, not enough water to the surface to keep my grass green in these hot days.
esshup, the effluent is absorbed into the ground.

I'm told it will be about 15,000 if it goes good.

I just had a septic system installed. This is the sprinkler kind that waters the field. $10,000.

That is a very good price, I havent seen one put in around here for much under 20K in a long time, there can be around 12K in materials costs, depending on the design, without figuring any labor, and they are very labor intensive to install.

Thanks, I won't hold my breath on that price.

I talked to another builder and he was talking some type of pumped system. I think he said pressurized.

Opposite side of the hill from the pond. I have seen septic systems fail. You wouldn't want that black effluent going into the pond.

It will be on the opposite, for sure. Thanks for all the help guys.
