(A) The top of the well shall be equipped with an approved sanitary well seal that is extended at least 12 inches above the lowest part of the basement floor and 6 inches above the floor directly adjacent to the well. (B) The well pit floor shall be at least 6 inches above the basement floor and sloped to the drain away from the well casing. (j) No pump shall hereafter be installed that uses the well casing for a vacaum line purpo,;e, nor shall any pump be installed having a buried horizontal suction pipe between the building and any below - surface pitless well, except where the suction pipe is encased in pressure pipe.

Each private water supply system must produce a minimum of 1uGU gallons of water per hour for a period of at least 3 hours of test pumping without an appreciable drop in the static level. For residences which have, nr wre to have, more than 2j bathrooms, the minimum well size shall be 4", whieb well shall test pump for 3 hours at not less than 1200 gallons per hour with no appreciable drop in the static level. The owner and inspector shall have the right to observe this test, measure the well or have said well checked to his satisfaction. All such wells shall be fitted with a permanent pump which shall produce not less than 50% of the test pumping rate, but in no case shall the permanent pump produce less than 500 gallons per hour at a pressure of 40 pounds per square inch. 17.08 Log required. A log of the well shall be made showint the nominal size as ep of the casing from outside ground elevatio;L. This log shall also state the results of a flow test made at the completion of the well, the static level of the water in the well and the drop in feet from the static level after pumping at the specified rate per hour for 3 hours. One copy of the log shall be filed with the Village Building Inspection Department and one copy posted in the building near the electric service box. 17.09 Cleaning Before Use. Drinking water supply systems must be disinfected Tollowing cons ruction or alteration. One pound of calcium hypochlorite mixed with 5 gallons of water shall be poured into the well and allowed to remain in the well and supply system for at least 12 hours, following which the water shall be pumped to waste until the odor and tast of the chemical has disappeared. 17.10 Abandoned Wells. Until a well is permanently abandoned, all provisions for pro ec ion of the water against contamination and pollution and for maintaining satisfactory sanitary conditions around the well shall be carried out to the same extent as though the well were in routine use. When a well is permanently abandoned a well permit must be obtained. The well shall be disconnected from the system and the hole filled to prevent contaminating materials from entering the water bearing ground formations through it. The inspector shall witness the filling of the well. Concrete or cement grout are the most satisfactory filling materials. If the well is so large that the use of these materials is not practical, the filling material selected shall be such as to restore natural conditions as far as possible. Neat cement grout, concrete or puddled cla; are satisfactory for filling.parts of wells in rock formations and natural earth or puddled clay may be used in drift sand and gravel sections of wells. In any case, the top ten feet of any permanently abandoned drilled well shall be filled with concrete. 17.11 Wells for Disposing of Wastes. The construction of a well for the purpose of disposing of any iqui , including surface water, air conditioning, or commercial wastes, shall be prohibited unless authorized and approved by the State of Minnesota Water Polution Control Commission. 17.12 Inspection. The Village Building Inspection Department must be notified 'Te rete well is test pumped, as in Section 17.07 or abandoned as in Section 17.10. The Department reserves the right to re- quire inspection of every well, or to spot check in lieu of checking every well, an may inspect the work in progress, the materials, testing, measurements, etc. at their discretion. Any licensee in violation of this section shall be subject to fine or imprisonment, as well as correction of work or materials that do not conform to this ordinance. The well contractor can proceed with his work if the Inspector does not visit the site to check on test pumping within 4 hours after the well contractor notifies the Village Inspection Department of testing operations. If upon inspection the inspector discovers that any part of the system is not constructed in accordance with the minimum standards provided in this ordinance, he shall give the applicant written notification describing the defects. The applicant shall pay an additional fee of $5.00 for each reinspection that is necessary. The applicant shall be responsible for the correction or elimination of all defects, and no system shall be placed or replaced in service until all defects have been corrected or eliminated. 17.13 Objectives.
