(a) Design data. A report, written by the designing or consulting engineer, shall:

1. (1) Be presented with all engineering plans; and
2. (2) Give all data upon which the design is based, or which is required for the complete understanding of the engineering plans.

(b) Surface water supply.

1. (1) If a surface supply is proposed, the nature and extent of the watershed with special reference to its sanitary condition and anticipated maximum and minimum water yield shall be fully and explicitly discussed, together with proposed methods and rules for the prevention of accidental or other pollution.
2. (2) A small scale map of the watershed, showing the roads and number and character of the buildings, shall be included in the report.

3. (3) Other features that should be discussed in the report are:

   1. (A) Storage;
   2. (B) Capacity;
   3. (C) Average depth;
   4. (D) General nature and area of the storage reservoir;
   5. (E) Probable water quality of the source; and
   6. (F) Proposed treatment processes.
4. (4) Treatment must be based on a thorough study of raw water quality.

(c) Ground water supply.

1. (1) If a well supply is proposed, the number, depth, size, and construction, method of pumping, type of strainer, geological formations through which wells will be drilled, and probable yield of the wells shall be given.
2. (2) Treatment must be provided based upon a thorough study of raw water quality.
3. (3) If collecting galleries are to be used, describe their construction.
4. (4) A map shall be submitted showing the location of all buildings, privies, sewers, underground conduits, or other possible sources of contamination within one thousand three hundred twenty feet (1,320’) of the proposed wells, galleries, or gravity conduits.

(e) Estimate of cost.

1. (1) An estimate of the cost for the construction of the water supply, source of supply, water treatment plant, and/or distribution system shall accompany all engineering plans.
2. (2) The estimate shall include quantities of the necessary materials.

(f) Plan review fee.

1. (1) In accordance with Acts 1965, No. 1965 as amended (Arkansas Code § 20-7-123 et seq.), a review fee of one percent (1%) of the estimated cost shall be submitted with the engineering plans and specifications.
2. (2) The maximum fee is five hundred dollars ($500).
3. (3) A minimum fee of fifty dollars ($50.00) is required.
4. (4) Unless the maximum fee is paid, a detailed cost estimate must accompany the engineering plans and specifications.
5. (5) No fee is required for preliminary engineering reports.
