KENNETH THURMON D, D.D.S. <br />JE55 wAYNE WEST, R. PH. <br />Subject:, Industrial Plant Water and Sewerage Facilities <br />Chemline Corporation - La Porte Plant <br />Harris County, Texas <br />Dear Mr. Patrick; <br />We have recently received the planning material which you prepared for the <br />subject water and sewerage system construction. It is noted that the water <br />system is to consist of approximately 630 feet of 2 inch steel water line, <br />tied in to an existing 6 inch water line of the City of La Porte, to provide <br />water for human consumption at the office building and shop, and for dust <br />control at the mixing tank. The sewerage system is to consist of a pump" <br />station with duplex pumps, and approximately 2450 feet of 4 inch polyethylene <br />plastic force main. The above facilities are to convey the sewage .to an <br />existing manhole of the City of La Porte, with treatment-to be accomplished <br />by the City's treatment facilities. <br />We have completed our review of the above planning material. and find it <br />appears to have been prepared in accordance with good public health engineering <br />practices and meets our current standards, provided that the steel pipe used <br />in water line construction meets AWWA standards, that the water line and all <br />appurtenances thereof are sterilized with a 50 ppm chlorine solution for 24 <br />hours and bacteriological samples are collected and found. to contain no coliform <br />organisms prior to being placed in service, and that the potable water inlet <br />into the mixing, tank is provided toith a suitable air gap to preclude any <br />submergence•of the potable water outlet. <br />Your assistance in submitting this planning material for our review is appre- <br />ciated and it is hoped that the above facilities can be provided at an early <br />date, If we may be of assistance in the future, please let us know. <br />Very truly yours <br />Mark V.
