Sanitary Sewer Questions

Hello

My wife and I are looking at a lot in North Dakota. The lot sits about 200 feet from the city sanitary sewer. A city employee who works with this said the pipe he esitmates is about 48-54 deep.

I read that you need 1/4 per foot of slope for sanitary sewer systems. I think this means that over 200 feet i need just over 4 feet from start to connection.

Am i correct my assessment above?

What options does one have in instances like this?

I should also note that i haven't checked yet with the city but it is not allowed to have a septic system. I am going to do some additional check on this however.

If the city would allow for septic. Is installing one similar in cost to connecting to city sewer? What is the difference in cost between the 2?

Thanks for the help.

 

Yes, normal minimum slope is 1/4" per foot of run.

Personally, no way would I pay to install and maintain septic when hookup to city sewer is available.

 

I do NOT think the city will allow you to install a septic system. When a city expands they usually require those already on septic to disconnect from their septic and connect to the sewer. Plus, a septic system will be much more expensive than tying into the sewer.

If the house is too far from the sewer for a gravity system you will need to install a collection/pump tank. When the tank is full the pump turns on a pumps the effluent out to the sewer. With this system the elevation doesn't matter.

 

Thanks for the replies. So if you do a pump or lift station does that sit in your house or to keep it under the frost line does it sit buried under the ground or how does that work? I would assume this all has to stay under the frost line which here i think is just under 48".

 

The ones I have seen are similar to a septic tank though possibly smaller. Usually they are outside and have an access riser so you can assess the pump and float switches for servicing.

 

I would do a little research on what contractors install the sewer laterals in the area and are bonded for connecting to the city sewer. I am sure they could answer all your questions pretty quickly and give you an idea of cost. You are just looking at a lot at this point so no use asking for a bid just yet.
