New Orleans New Filler Plant

New Orleans New Filler Plant

Excavations have been completed for the foundation of the filters for the new $2,000,000 filtration plant for New Orleans, La., which will be a duplication of the present plant. According to Superintendent Earl it is expected that the new unit will be completed some time in 1927 and will double the New Orleans water supply. The present nominal capacity of the system is 40,000,000 gallons a day, but this has been exceeded by several millions on many days.

Referring to the problems connected with the new plant’s construction Superintendent Earl has pointed out that work must be executed alongside of and tying into existing structures in continuous operation.

Regarding the total water consumption in New Orleans from 1911 to 1923 inclusive, the superintendent pointed out that there appears to have been no material difference in the amount of water furnished to the distribution system during 1920, 1921, 1922 and 1923.

The records show that this was accomplished despite the fact that 10,000 more premises were served in 1923 than in 1920. and the revenue from the sale of water has increased more than 11 per cent, without any increase in water rates. Seventy per cent, of the water delivered into the distribution system was recorded by meters in 1923. Careful study of a tabulation has been made from year to year, as issued with each additional year’s record added, to see if any evidence existed indicating error in the assumption of 20 per cent, of the recorded flow through meters as flow passing them unrecorded, and 3,000 gallons per mile as leakage from city side of system.

The superintendent declared that to date these assumptions appear to fit all of the known conditions as well as any other possible assumptions “If by chance, they are actually true” the superintendent continued, “it is obvious that for 1923, if meters could record the actual flow passing them, instead of 80 per cent, thereof, the recorded flow would have been 12,306,000,000 gallons instead of 10,255,000,000 gallons or nearly 84 per cent, instead of only 70 per cent, of the total supply. The difference of 2,051,000,000 gallons represents loss because meters pass certain small rates of flow resulting from leaks and wastes going on constantly 24 hours a day, entirely unrecorded.

“With water even at 10 cents per thousand gallons, this assumed unrecorded flow represents a loss of $250,000 a year. It may easily average a great deal more or a little less.”

During the last year there was an increase in the amount of water consumed by institutions classed as free consumers, in 1922 the amount was 662,027,000 gallons and in 1923 it was 725,186.000. The hospitals headed the list with 179,950,000 gallons and schools next with 144,802,000. The asylums are third with 95,603,000 gallons. The other free consumers are: engine houses. 14,021,000 gallons: libraries, 10,902,000 gallons: markets, 47,637,000 gallons: municipals, 64,511,000: parks, 35,354,000 gallons: police stations, 30,423,000 gallons: sewage and water board, 76,666,000 gallons and water troughs, 25,317,000 gallons. The approximate number of premises supplied (average for year) during that same period follows: 31.000 in 1911: 39,000 in 1912 : 50,000 in 1913: 59,000 in 1914: 67.000 in 1915: 73,000 in 1916 : 76,000 in 1917: 77.000 in 1918: 78,500 in 1919: 80,000 in 1920 : 81,500 in 1921: 84.500 in 1922: 89.000 in 1923.
