    Agreed! : )

    Local township engineer is ok with the plan, but said you have to see if I can get exception permits from DEP and HOP (phone conversations look ok, but in committee is another thing)

    I'm also revisiting the HDD option (pic attached)

    .…... anyone operate an HDD rig before?

    Thinking about renting a rig and trying it out myself!

    ..…... if it works out well for this pipe install, I'll run it under horizontally on the main highway here for about 500ft and chemically "frack" the hard rock ground strada to increase the water flow into our well water.

    ( just kidding Leonz!! ) : )

    Hello Rick,

    Did you contact the fellow that I suggested you contact to ship all your excess water by rail to communities that desperately need potable water?

    You have a straight shot for that bore, you need a launch pit at the drain line from the apartments to the septic tanks and reception pit near the sanitary sewer line to connect the new branch lateral to the main sewer line with a saddle tap. You are at the point where you need a macerator/grinder for the discharge of the solid waste if they let you create a small diameter force lateral rather than a 4 inch gravity sewer thjaty will require a 4 inch bore and 6 inch back reaming for the pipe.

    The drilling contractor will be the one to decide where the launch pit and reception pit will be as the launch pit will also be where the drilling mud cIeaning plant will be located as you need to be able have the waste mud and gravel removed.

    Hi Leonz! : )

    "Did you contact the fellow that I suggested you contact to ship all your excess water by rail to communities that desperately need potable water?"

    no! …. not yet! That project is on hold (another project needed my immediate attention)

    "You are at the point where you need a macerator/grinder for the discharge of the solid waste if they let you create a small diameter force lateral …… "

    My experience with the sewage lift stations within the motel industry , I prefer not to use a macerator or grinder pumps. I screen (see pics) the really bad stuff (needles and latex stuff) so the pumps never have to deal with them.

    I use a stainless steel screen to do this (pictured)

    Hey!

    DEP said they would entertain my plan to entrain my 2" HDPE thru the culvert! (preparing the required permits now!) He said I'm making an unusual, but reasonable conformance to the code requirements.

    Their main concern was that I first get my PENDOT "HOP" (permission to construct within there right of way). After that, they will review my stream/culvert crossing request.

    The township already indicated probable acceptance to the plan, but only after approval of the other agencies.

    This might be a first! : )

    @PC7060

     "They own the entire culvert and, as Br. Jamie said, will not allow a reduction in capacity."

    The culvert is a 100 year flood design (Big) with very low flow stream running thru it. Its about 5ft high by 12 ft wide and 30ft long.

    Me putting in a 2" HDPE in the absolute bottom corner of this massive box culvert is not going to change any measurable designed flow capacity issues.
