Pump Discharge, Well Pit. No well shall hereafter be installed in a pit below the surface of the ground unless such well pit is in an alcove opening directly into the main basement area of the building being served by the well. (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 ahal 1 be at least 6 inches above the base- ment floor and sloped to the drain away from the well casing. (C) Pump restrictions, no pump shall hereafter be installed that uses the well casing for a vacuum line or pressure line purpose, nor shall any pump be installed having a varied horizontal auction pipe between the building and any below -surface pitless well, except where the suction pipe is encased in pressure pipe.

Check valve (if required) on discharge l..ie between ,,ump and tank on well side of union or dresser coupling. Automatic air re -charge system or air saver type tank. -4- Section 6. Community Water Systeme. Community water systems or wells supplying 3 or more residences shall be permitted only after plans have been submitted to, and approved by, the Village Council or its agent. For all community water systems the Village shall employ a consulting engineer to assist the Village Engineering Department in the approval of plazas and in the supervision of the systems duiiog construction. The full fee paid to such consulting u:ngineer shall be borne by the owner. Section 7. Test Pumping Requirements. each private water supply system must produce a minimum of 1200 gallons of water per hour for a pet-iod of at least 3 hours of test pumping wi`hout an appreciable drop in the static level. The owner and inspect- shall have the right to observe this test, measure the well or have said well checked to his satisfac- tion. All such wells shall be fitted with a permanent pump which shall produce not less than 5%o of the test pumping rate nor more than 75' of such test pumping rate, but in no case shall the permanent pump produce less than 600 gallons per hour at a pressure of 40 lbs. Section 8. Log Required. A log of the well shall be made showing the nominal size and depth of the casing from outside ground elevation. This log shall also state the results of a flow test made at the com- pletion 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 rate of 600 gallons 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. Section 9. Cleaning Before Use. Drinking water supply systems must be disinfected following construction 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 taste of the chemical has disappeared. Section 10. Abandoned Wells. Until a well is permanently abandoned, all provisions for protection 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 poss- ible. tr-iat cement grout, concrete or puddled cl�iy are satisfactory for f:.- ..-ig r•w,ts of wells in rock formations ani natural earth or puddled axay may be used in drift sand and gra•-J1 sections of wells. In any case, the top ten feet of any permanently abandoned drilled well shall be filled with concrete. -5- Section 11. Wells for Disposing of Wastes. The construction of a well for the purpose of disposing of any liquids, including surface waters, air conditioning, or commercial wastes, shall be prohibited. Section 12. Inspection. The Village Building Inspection Department must be notified before the well is test pumped, as in Section 7 or abandoned ae in Section 10. The Department reserves the right to require inspection of every well, or to spot check in lieu of cb�icking every well, and may inspect: the work in progress, the materials, testingg maasursments, etc. at their discretion. Any licenses in violation of this ordinance 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 3 hours after the well contractor notifies the Village Inspection Department of testing operations. If upon inspection the inspector discovers that azW 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 35.00 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. Sec. 13, Objectives. The objectives of this ordinance are to provide adequate and safe domestic water supply. Any system of special, unusuil or new design which will satisfy the stated objectives may be accepted as complying with this ordinance, and any permit granted for the construction, installation, alteration, or repair of any such special system shall be subject to such conditions and guarantees as n,ay be stated in the permit. This ordingnoe does not apply to irrigation or -industrial purposes. Shopping Center wells and la-rger system will require the State Board of Health approval. Consideration should be given to locating shopping center wells away from buildings with separate power source, so that they may be used to fight fires. This ordinance applies to wells for domestic and residential use. Seo. 14. Penalties. Any person, firm or corporation violating any of the provisions of this ordinance shall be guilty of a misdemeanor, and upon conviction thereof shall be fined in an amount not to exceed 3100.00 or imprisoned for not to exceed 90 days.
