(Th~ inspection revealed a growth on the interior surface <br />of the pipe which apparently increa"ed friction and reduced capac- <br />ity_ Chlorination of the water was started July 7, and by July 31 <br />the delivery had risen from 92 cubic feet per second to 100 c_f_".) <br /> <br />Operation of eitl'II_' alld '"ltlnl/t groves <br /> <br />The 65 acres of citrus and 22 acres of walnut groves near La <br />Verne owned by the District and operated under the superyision <br />of the chief operation and maintenance engineer were reduced in <br />size thi" year to make way for new construction_ An area of about <br />8.5 acres was cleared of trees for the first expansion of the softening <br />and filtration plant facilities_ Normal operation includes cultivating. <br />pruning. irrigating. fertilizing. spraying. and dusting_ It was neces- <br />sary to do some light firing on three nights during the winter for <br />frost protection. Six trees died of quick decline as the disease made <br />its first appearance in District groves. Sixty-five young trees were <br />planted to replace nonproductive trees. A combination of late pick- <br />ing schedules and late rains caused a considerable loss of navel <br />oranges because of rotting and dropping of fruit before harvesting. <br />Total income from sale of oranges, lemons, and walnuts for the <br />fiscal year was $13,134.97. Operating expenses were $16,945_19, <br />including $2.738.62 for taxes, making a net loss for the year of <br />$3,810.22. The total net profit from the groves since beginning of <br />operation in July 1936 is $97,270.20. <br /> <br />Water softening IInd jiltratioll pla."t <br /> <br />The water softening and filtration plant operated continuously <br />without shutdown, during the entire fiscal year 1947-48_ Because <br />the increased demand for water required operation of the plant for <br />58 days at flows greater than the presellt designed capacity of 100 . <br />million gallons per day, it. w~." llPr.p~~ary to discontinue the normal , <br />practice of partial lime treatment for part of this period due to <br />inadequate clarification ill the settling basins and consequent over- <br />loading of the filters_ During the period" of lime shutdown only <br />
