<br />According to t01mspeople l;ho have lived in Pico quite some time, <br /> <br />the period of turbidity during spring runoff could last a maximum of <br /> <br />6 weeks, and there are 8 weeks maxirolllll during the SUlJU1ler in ..moh <br />Silver Creek could stay turbid due to afternoon rains. 'Ibis makes a <br />ma:dmuIIl period of 14 weeks of treatlllent for turbidity that should be <br />expected . <br />The proposed treatment facility has a chemical feeder that treats <br />the water w.i th a coagulant before filtration. The coagulant is fed <br />automatically at a prescribed dosage. The water should also be treated <br />wi th a small amolU1t of neutralizing agent to reduce the acidity of the <br />water~ The acidity in the l;ater could corrode the lines and shorten' <br />their lives. <br />The .later quality tests sho.., this water to be completely acceptable <br />for industrial use without treatment. Therefore, the industrial water <br />will be taken out of its present facility and used from an entirely <br />different intake than the conunercial and residential water. <br /> <br />The supply outlet in the 222,350 gallon capacity intake pond is <br />designed to draw the water at a depth of ten to twelve feet on the lower <br />edge of the pond allowing maximum retention time for settling solids <br />and leav.ing one and one-half feet of the bottom for sludge accumulation. <br />Also, the outlet is provided .dth a screen to prevent debris or fish <br />from entering the system. <br />,The pond is designed to be easily cleaned. The vertical tl-1elve inch <br />corrugated metal pipe will be fitted with a collar that can be pulled out. <br />The pipe 'leighs 10,1 pounds per foot, so the operator must lift 130 pOlU1ds <br />to rem.ove the pipe to drain the pond. The pipe is placed directly below <br />the catl-lalk in:~entiona11y to allw the operator to use a come;'along <br />to jerk the pipe if necessary, <br /> <br />- 27 - <br />
