Standard configuration for utilities shall be as such: Potable water spigot located off rear right corner of campsite. Electric pedestal about 12’ from potable water spigot. Sewer about

25’ from potable water spigot. Water and sewer lines shall not cross each other and remain far enough apart and installed to meet MDH laws, codes, and guidelines. MDH laws, codes, and guidelines shall supersede the distances specified above and on attached drawings. See attached drawings for additional details.

The contractor may use the following existing utilities while completing the work at no cost: Contractors may use restrooms located within the USACE, Leech Lake Dam Recreation Area that are available to the public. The contractor can utilize USACE potable water and/or electricity. Use of such utilities must not impede traffic on roadways. All impacts to traffic must be coordinated with USACE staff in advance.

A. Sewer. The existing concrete sewer manhole (which is the starting point) is about 10’ deep and consists of approximately 24” diameter cover on top of a concrete conical riser. There is a seam between the concrete manhole and the conical riser. The depth of this seam is about 4’ from the ground surface. Care must be taken not to damage this seam. Sewage flowing through this manhole runs at the bottom of the manhole. Trench in new 4” SDR Sewer Line starting from and tapping into the existing concrete sewer manhole (see attached drawing for location of this manhole) in-series to the specified locations adjacent to the new campsites. Cleanout riser pipes must be installed at all angles and every 100 feet of distance as applicable to the contractor’s design. Holes cut through the manhole must be a clean cut and shall utilize a modular mechanical sealing system that creates a permanent seal for cylindrical objects that pass through a barrier. A sealer designed for septic/sewer/manholes shall be used to seal any gaps. Sewer lines shall be installed with tracer line attached for future locating needs.

Sewer Design. Contractor shall submit a design that details the sewer installation. The sewer design shall be submitted at the on-site initial meeting. The Sewer Design shall be approved by the Contracting Officer prior to start of work and shall contain the following information:

a. Layout drawing of new sewer plumbing and depth.

b. A list of components with spec sheets.

B. Potable Water. Photos of existing manholes are attached for reference below. Waterlines will be constructed to allow for winterization each fall and restarted each spring by USACE staff. Potable water lines shall be installed with tracer line attached for future locating needs.

All water standpipes specified shall be installed in concrete pads at ground level appropriately sized to support the standpipes. All shut off and drain valves specified shall consist of ball valves. Utilize underground horizontal directional boring to install a new seasonal 200 lbs. poly 2” potable water line with shut off valve starting from and tapping into the existing approximately 24” diameter x 4’ deep, concrete manhole located near campsite #57 that contains approximately 2-1/2” copper piping that exists approximately 12” below the ground surface inside the manhole. The existing concrete manhole located near campsite #57 (which is the starting point) contains an existing gate valve that shall be replaced with a ball valve at the same time the contractor “T’s” into the existing water line inside of the manhole. The contractor shall “T” into the existing copper waterline “upstream” of the new ball valve being installed. Directional boring and new waterline shall be installed to the specified location near the new campsites and install a new approximately 24” diameter PVC manhole with a fiberglass reinforced plastic cover that shall contain a ball shut off and drain valve. Then extend waterline and install a 36” high, 2” galvanized standpipe adjacent to the manhole that includes a shut off ball valve near the top and a hose bib on top. Then “T” underground adjacent to the standpipe and then trench in-series to each of the three new campsites with new ¾” poly waterline including 18” galvanized standpipes, with shutoff valves, and hose bibs on top for each. Place about 12” of approximately 1” rock at the base of the new manhole. Holes cut through the manhole must be a clean cut and shall utilize a modular mechanical sealing system that creates a permanent seal for cylindrical objects that pass through a barrier. A sealer designed for septic/sewer/manholes shall be used to seal any gaps or holes where that system is not applicable.
