(2) The spring outlet shall not be located in a one-hundred year flood plain.

(C) A diversion ditch shall be located on the uphill side of the spring to divert surface water away from the spring construction. The discharge from the diversion ditch shall be a minimum of twenty-five feet and downslope from the spring.

Manholes, if provided, shall be a minimum of twenty-four inches in diameter and shall have a watertight curb with edges projecting a minimum of eight inches above the level of the surrounding surface. The edges of the manhole cover shall overlap the curb and extend downward a minimum of two inches. The spring box cover or manhole cover shall be provided with locks, bolts, or equivalent means to minimize the danger of contamination, accidents, and unwarranted entry.

(J) All joints, connections, and other seams between component parts of the spring construction shall be sealed with nontoxic waterproof material that meets ANSI/NSF standard 61 or materials approved by the department to prevent contamination or the entry of unwanted water.

(K) The following start up disinfection procedures apply to spring boxes:

(1) All loose debris, sediment, mineral encrustation and bacterial slime shall be removed from the spring box prior to disinfection.

(2) A solution of two hundred fifty milligrams per liter of chlorine shall be prepared in a storage container. The quantity of solution prepared shall be of sufficient volume to disinfect the entire spring box and all related storage or pressure tanks, existing plumbing and attached fixtures.
