<br />~~S6 <br /> <br />METROPOLITAN WATER DISTRICT <br /> <br />Total income from sale of oranges, lemons, and walnuts for the <br />fiscal year was $16,266.92. Operating expenses were $19,271.88, <br />including $3,075.34 for taxes, making a net loss for the year of <br />$3,004,96, The total net profit from the groves since they were <br />purchased in July 1936 is $94,265,24, <br /> <br />Water sojtening and filtration plant <br /> <br />Except for six days of shutdown in March, the softening and <br />filtration plant operated continuously during the fiscal year 1948- <br />49. This, the first complete shutdown of operation since the plant <br />was put into service in 1941, was necessary in order that all the <br />water might be drained from the plant and pipe lines to permit <br />the installation of piping connections between the existing facilities <br />and the new plant expansion under construction. Because the in- <br />creased demand for water required operation of the plant for 69 <br />days at flows greater than the present designed capacity of 100 <br />million gallons per day, the hardness of the plant effluent water <br />exceeded the desired value of 125 parts per million for a part of <br />this period, Partial lime treatment preceding zeolite softening was <br />used for a total of approximately four months during the fiscal <br />year, while zeolite softening alone was used the remainder of the <br />time. <br />A new peak flow through the plant was reached on June 24, 1949 <br />when 203,6 cubic feet per second, or 131.6 million gallons per day, <br />were softened. This is 31.6 per cent above the present designed <br />capacity of the plant. The monthly average rate of flow ranged <br />from a maximum of 168.5 cubic feet per second, or 108.9 million <br />gallons per day, in August 1948 to a minimum of 52.6 cubic feet <br />per second, or 34 million gallons per day, in January 1949. The <br />average daily flow through the plant for the fiscal year 1948-49 <br />was 106.3 cubic feet per second, or 68.7 million gallons per day, an <br />increase of 5.0 per cent over the corresponding figures for the pre- <br />ceding fiscal year. <br />Due to increasing age and wear of the equipment considerable <br />repair, replacement, and maintenance 'were required, All the zeolite <br />effluent valves on the north side and one on the south side of the <br />softener building were completely overhauled. New metallized <br />leaves and new hook rods WE'rE.' in~t~llprJ in these valves. A new <br />guide bearing was installed on the east flash mixer. The old dilu- <br />tion valve in the zeolite building was replaced by a new one. The <br />tube ends in the carbon dioxide boiler were rolled and calked to <br />
