  B. Information Required.

  Plans submitted for review shall be drawn to scale, 1" = 10', 20' or 30', or other scale as approved by the division. Plans shall be prepared in such a manner that the contractor can read and follow them in order to install the system properly. Depending on the individual site and circumstances, or as determined by the division, some or all of the following information may be required.

  1. Applicant Information.

  a. The name, current address, and telephone number of the applicant.

  b. Complete address, legal description of the property, or both to be served by this LUWD system.

  b. North arrow.

  c. Lot size and dimensions.

  d. Legal description of property.

  e. Ground surface contours, preferably at 2 foot intervals, of both the original and proposed final grades of the property, or relative elevations using an established bench mark.

  g. Location and dimensions of paved and unpaved driveways, roadways and parking areas.

  h. Location and dimensions of the essential components of the wastewater system including the replacement area for the absorption system.

  i. Location of all soil exploration pits and all percolation test holes.

  j. Location of building sewer and water service line to serve the building.

  k. Location of sewer mains, manholes, clean-outs, and other appurtenances.

  l. Location of easements or drainage right-of-ways affecting the property.

  m. Location of all intermittent or year-round streams, ditches, watercourses, ponds, subsurface drains, etc. within 100 feet of proposed LUWD system.

  n. The location, type, and depth of all existing and proposed water supply sources

  o. Delineation of all drinking water source protection zones located on the project site.

  p. Distance to nearest public water main and size of main.

  q. Distance to nearest public sewer, size of sewer, and whether accessible by gravity.

  3. Statement with Site Plan.

  Statement indicating the source of culinary water supply, whether a well, spring, non-public or public system, its location and distances from all LUWD systems.

  4. Soil Evaluation.

  a. Soil Logs, Percolation Test Certificates, or both.

  b. Statement with supporting evidence indicating the maximum anticipated ground water table and the flooding potential for LUWD system sites.

  5. Relative Elevations.

  Show relative elevations of the following, using an established bench mark.

  a. Building drain outlet.

  b. The inlet and outlet inverts of any septic tanks.

  c. Septic tank access cover, including height and diameter of riser, if used.

  d. Pump tank inlet, if used, including height and diameter of riser.

  e. The outlet invert of the distribution box, if provided, and the ends or corners of each distribution pipe lateral in the absorption system.

  f. The final ground surface over the absorption system.

  6. System Design.

  Details for said site, plans, and specifications are listed in Design in Section R317-4-6.

  a. Schedule or grade, material, diameter, and minimum slope of building sewer and effluent sewer.

  b. Septic tank and pump tank capacity, design, cross sections, etc., materials, and dimensions. If tank is commercially manufactured, state the name and address of manufacturer.

  c. Absorption system details, including the following:

  i. details of drop boxes or distribution boxes, if provided;

  ii. schedule or grade, material, and diameter of distribution pipes;

  iii. length, slope, and spacing of each absorption system component;

  iv. maximum slope across ground surface of absorption system area;

  v. distance of absorption system from trees, cut banks, fills, or subsurface drains; and cross section of absorption system showing the:

  (1) depth and width of absorption system excavation;

  (2) depth of distribution pipe;

  (3) depth of filter material;

  (4) barrier material, i.e., synthetic filter fabric, straw, etc., used to separate filter material from cover; and

  (5) depth of cover.

  d. Pump, if provided, details as referenced in Section R317-4-14 Appendix B.

  e. If an alternative LUWD system is designed, include all pertinent information to allow plan review and permitting for compliance with this rule.

  C. Plans Submitted.

  1. All applicants requesting plan approval for a LUWD shall submit two copies of the above required information to enable the division to retain one copy as a permanent record.
