    Hello,

    I am building a house on a hillside and I have a decision to make on sewage. I can either install a grinder pump and pump sewage up to the municipal sewer line above the house or install a gravity septic system below the house.

    Any suggestions on which will be more reliable and less long term maintenance?

    Thanks in advance!

    Not sure what a new septic system would cost in your area but in my area they cost between $20 and $30 K.

    I'm sure you'll hear a lot of pros and cons on either arrangement.

    Personally, I would opt for the "pumped to the municipal sewer line above the house", with one caveat. That is, a container/tank on site, sized to allow me to flow by gravity into it from the house and arranged with a level control to have grinder pump start and stop less frequently than it would with a smaller container. The size of the larger container could easily be based on a comfortable margin of safety in case the pump broke down and/or power went out(in the absence of a standby generator).

    How high would you have to pump?

    Thanks for the reply. The sewer is probably 60 ft above the tank and about 50 ft away in lateral distance.

    Yeah, the quote I got was about $25k for the septic, but with grinder pump will be about $15k with a $2k tap in and whatever the cost of pipe is to the public sewer, so I’m not sure how much I will really save with sewer.

    Yes I understand.
    You can estimate your electrical cost to pump as well as other cost related to each system. But in the long run you really don't know what will come along.
    I simply like the idea of getting away from a septic system and the potential problems in the long term. Although I haven't had any problems with my septic system in the 43 years I've lived here. KNOCK ON WOOD. Could have something to do with the fact that I live adjacent to a small wet land area and who knows where all my leachate is going?

    Just out of curiosity, is that pump a package system including a small sump and level controls, completely installed for $15K? I would assume so.

    In most jurisdictions, if you can connect to a regulated sewage system, you are required to make the connection.
