Section 61-58.1.C - Engineer's Report

A preliminary engineering report shall be prepared in triplicate for each new surface water intake, surface water treatment plant, expansion or modification to an existing surface water intake or surface water treatment plant, or other projects deemed necessary by the Department. This report shall carry the seal and signature of a professional engineer. The engineer's report shall, where pertinent, present the following information:

(1) General Information (Required for Each Report):

(a) name, address, phone number of owner, corporation, town or utility as well as name of responsible officer;

(b) name, address, phone number of engineering firm and name of engineer responsible for design;

(c) general description of service area and surroundings (type of economy, estimated percent residential, estimated percent industrial, terrain, location, possible rate of development);

(d) number and type of customers to be served, (i.e., domestic, industrial, commercial, agricultural, etc.); and,

(e) approval of any land use and development by area planning council which has jurisdiction.

(2) Surface Water Sources

(a) location map including latitude and longitude of intake;

(b) name of source(s), type (river, lake, etc.) and classification (Water Classifications and Standards, R.61-68);

(c) watershed area;

(d) expected 7Q10 flow and lowest flow of record of source(s);

(e) name and type of discharges within ten (10) miles upstream (industrial, agricultural, municipal and other);

(f) chemical and bacteriological analyses of raw water. This analysis must include all parameters addressed in R.61-58.5;

(g) distance from raw water supply to reservoir or plant;

(h) proposed pumping rate from source;

(i) general description of intake and pump house; and,

(j) a detailed engineering and economic assessment on the feasibility of utilizing alternative water sources, or combinations of water sources, other than the proposed water source.

(3) Water Treatment Plants

(a) Projected maximum volume of water to be treated;

(b) Year when plant is expected to operate at its maximum capacity;

(c) If existing, present operating capacity;

(d) Location map of plant;

(e) Height above the one hundred (100) year flood plain based on the best information available;

(f) Land available for future plant expansion;

(g) Proposed treatment scheme shown in block diagram;

(h) Proposed design criteria (retention times, velocities, weir overflow rates, filtration rates, etc.);

(i) Description of proposed method of handling, treating, and disposing of wastewater from plant (includes clarification sludge, filter backwash water, brines, etc.);

(j) Name(s) and grade(s) of operator(s);

(k) For modifications to existing treatment plant, report must include: Present capacity of raw water pumps, and a brief description of what effect proposed modification will have on existing facilities including velocities and retention times through plant; and,

(l) Detailed description of any pilot testing to be performed.
