The preferred equipment for applying liquid chlorine isas solution-feed, vacuum- operated chlorinator: and al booster pump. The vacuum-operated chlorinator mixes the chlorine gas in solution water; the booster pump injects the chiorine-gas solution into the main to be disinfected. Hypochlorite solutions may be applied toi the water main with a gasoline or electrically powered  tot filla a container of! khown volume.  appurtenances.  02667-9    chemical-feed pump designed fori feeding chlorine solutions. Feed lines shall be ofs such material and; strèngth as to safely withstand the corrosion caused by the concentrated chlorine solutions andi the maximum pressures that may be created by the pumps. All connections shall be checked for tightness before the solution is applied: to the main. : : 5. Highly chlorinated water shall not! be released into? the distribution: system nor: shall be discharged into anys sanitary sewer manhole. or other sanitary sewer inlet. The chlorinated water shali remain int thel line until the chlorine residual drops! below! 5 ppm or dissipated by other prior approvedi methods. After this period, the water will be wasted by pumpingi intoi the air to dissipatei the remaining chiorine. residual. Pumping shall be at ar rate not to exceed 25 GPM. Pressure and nozzle: size: shalll be such as to produce an 8 foot (vertical): spray. The system should then be flushed with potable water and the sampling program started. Sampling shall consist oft taking atl least one per linei installation ànd one representative sample every! 5000f feet and ate each blow-off. The: samples shall then bet tested! bya a state approved laboratoryt fori indication of bacteriologically satisfactory water. Two successive negative. samples per line: segment willl be required for certification. Positive: samples will require, re-sterilization per:specifications. Three (3) copies of this laboratory test shall be submitted to The Town. 6. Contractor: shall coordinate alli filing, pressure testing, flushing, chlorination, and de-chlorinationwith the Town and shall payi for water used in the  process based on Engineer's calculations.  3.04 SAFETY  A. The Contractor: shall comply with ail applicable provisions of the. Federal Occupation 1. Where worki ist to be done in state maintained. right-of-ways, the Contractor shall contact the Department of.Transportation (local and/or districtoffice)to determine the peruse requirements: for. barricades; signs, etc.  Safety and Health Act. : "  : 3.05 FINAL CLEANUP  A. Immediatelyaftert the completion of the workfor any substantial unit or portion of it, the Contractor: shall remove all unused materials, refuse, etc., and shall leave the site  of the work naconditionsatisfacton; to The Town. 4. 1 :: .w : - :  : :  : 1. :  : a : e : :14 3ir -  : 1 544173  *.
