Application for permit must be accompanied with detailed plans indicating the contemplated improvement and must meet the specifications and requirements as set forth in Chapter 111-1/2, paragraphs 121 (a) through 121 (0) and amendments thereto, of the Illinois Revised Statutes under Department of Public Health. Section 23.504: Sterilization Procedures: All new water mains installed in the Village of Mount Prospect shall be sterilized in conformance with the following procedures. All sterilization of water mains shall be done by an experienced sterilization technician or specialist using these procedures, at which time and place the Director of Public Works of the Village of Mount Prospect or an authorized representative of the Village Of Mount Prospect must be present. The technician or specialist conducting the sterilization shall submit to the Village of Mount Prospect a certificate of insurance prior to commencing his testing. Sampling taps shall be provided on the water main every five hundred I (500) feet in order to afford representative water testing and sample cOllectio~. When long transmissibnal mains are constructed without side connections the distance between each tap may, at the discretion of the Director of Public Works of the Village of Mount Prospect or his authorized representative, be increased. In all cases, a minimu~ of two (2) sampling taps shall be required. Sampling taps shall be provided to collect a source sample and enough represen- tative water samples for laboratory examination. (a) Preliminary Flushing: Each valved section of the completed main shall be flushed prior to sterilization as thoroughly as Possiblell with water pressure and outlets available. If no hydrant is provided at the end of the main section, a tap shall be installed I at the main section extremity, large enough to develop a velocity in the main of at least 2.5 fps. The flushing operation shall be done after the pressure test has been made. (b) Sterilization: Before being placed in service all new mains and existing piping disturbed in any manner by the work shall be sterilized. Draining the water from existing piping or even lower- ing the water pressure more than one-half will constitute disturbance of the piping. The sterilization of water mains, valves and other appurtenances :incorporated into the main construction shall be done by chlorine gas water mixture. This shall be applied by means of a chlorinating measuring apparatus, with proper devices for regulating the flow and providing an effective diffusion into the water within the main being sterilized. /-... i......... ~ .. tbte: In certain instances when the use of chlorine gas is not practical, as in congested or confined areas, upon approval of the Director of Public Works of the Village of Mount Prospect, or his authorized representative, a chlorine-bearing compound of known chlorine content, prepared in solution form, may be substituted for chlorine gas. The recormnended chlorine-bearing compouns shall be high-test calcium hypochlorite (65-70 percent available Chlorine). In the preparation of this solution the powder shall first be made into a paste and then gradually thinned with water to approximately one percent chlorine solution (10,000 parts per million). The point of chlorine application shall be at the beginning of the water main construction and! or any valve section thereof, thereof, through a corporation cock installed close to and on the downstream side of the regulating gate valve controlling the flow of water into the main. The rate of chlorine application shall be in such proportion to the rate of water flow entering the main that the chlorine dose applied shall produce 50 parts per million (420 pounds per million gallons) chlorine concentration in the water within the main . During the sterilizing operations, valves, hydrants and other mechanical devices controlling the flow of water shall be operated to pennit full effectiveness of the chlorine. Valves shall be manipulated so that the strong solution within the main being sterilized will not flow back into the supply line nor flow into mains already in service. A chlorine concentration test shall be made, in turn, at each of the hydrants and/or taps provided for that purpose. (c) Retention Period: After the sterilizing operation has been completed and upon test proved satisfactory, the heavily chlorinated water shall be retained in the main long enough to destroy all non- spore forming bacteria. This period shall be at least twenty-four (24) hours. At the completion of the retention period the chlorine concentration of the water within the main shall be at least 25 parts per million (210 pounds per million gallson) of chlorine. (d) Final Flushing and Tests: After the required period of retention has elapsed, the heavily chlorinated water shall be flushed out completely to waste until the replacement water throughout the length of the main shall, upon test, be proven comparable in quality to the water supply source. When the water in the treated main shall have been proven comparable to that of the source, water samples shall be collected at each of the sampling taps and submitted to the laboratory on two (2) separate days. Under no circumstances shall such samples be collected from hydrants or unsterilized hose connections. All samples shall be taken in the presence of the Director of Public Works of the Village of Mount Prospect, or his authorized representative, and ' tpon completion of sampling all sample bottles shall be turned over to the Village. The Village shall transmit samples to the Cook County Health Department for analysis and written report. The cost of mailing or other expenses incurred by the Village in connection with sterilization shall be paid by the Pennitee. Should the results of the bacteriological examination prove satisfactory, the main shall be placed in service. All turning on and off of existing mains shall be done by or under the supervision of the Director of Public Works of the Village of Mount Prospect. Should the initial sterilization fail to result in approval, the sterilization procedure shall be repeated until satisfactory results are obtained. Section 23.505: Saving Clause: In the event that any section or sections or part or parts of section or sections of this Ordinance shall be held invalid by a court of competent Jurisdiction, then ~ .~, .~ /-.. the remaining section or sections or part or parts of section or sections shall hot be affected whatever by such finding, but shall remain in full force and effect. SECTION 2: This Ordinance shall be in full force and effect from and after its passage and approval in the marmer provided by law. AYES: 6 NAYS: o PASSED THIS 2nd day of January, 1968.
