WATER FOR ROSKILL

ONE TREE HILL CLERK S REPORT

QUANTITY AND CHARGES

Recently the Mount Roskill Road Board approached the One Tree Hill j Road Board asking for the conditions and charges for a supply of w ater. At a meeting of the One Tree Hill Board last evening, the clerk. Mr. A. Leese, submitted a report which was taken in committee. The report stated that for the seven months from April to October, inclusive, the weekly pumping did not exceed 1.500.000 gallons. The capacity ; of the pump was 3,025,000 gallons a week, so that after allowing for an increase in the district consumption . of 33 per cent, in five years, the board | could still with safety contract for the supply of 500,000 gallons a week ! for that period of the year. It would not seem desirable with the present facilities to contract for the supply of any water for the five ! months from November 1 to March 31. but it might be possible to do so for part of that time, when water was j available. The present daily consumption ot the eastern end of Mount Roskill varied from 46,000 gallons in July to! 93,000 gallons in February, so the j board could easily cater for Bast j Mount Roskills requirements for! seven months of the year for the next | five years at least. For the year 1925-1929 the direct charges for pumping amounted to j £ 1,652, but additional charges had to j be added. On the present consumption the j pumping and filtering cost 7.1,d a 1,000 gallons, but some of the charges were fixed and did not increase with an increased fiow of water. Electric power increased with pumping, so that half of the charges were affected by the fluctuation in the quantity of water pumped. Assuming that Mount RoskiU’s demand increased the water pumped by 25 per cent., the cost of pumping, would decrease by only 12S per cent. At the time of compiling the report no definite figures as to Mount Roskili’s requirements were to hand. Assuming that Roskill would take an average of 60,000 gallons daily for 210 days the total for the seven months j would be 12,600,000 gallons. At lOd , a 1,000, the cost would be. £525, of ! which one-third, £175, would be net! profit. Mount Roskill would save £262, the difference between the proposed | charge of lOd and the oity price of Is 3d. Before a supply could be given it ; would be necessary to make a con- j nection at Greenwood’s Corner and j instal a four-inch meter and the necessary valves. The estimated cost was - £IBO. The clerk suggested that an offer at lOd a 1,000 gallons for five years be made to Mount Roskill, and if it was accepted the net profit be set aside for the purpose of purchasing a | large pump when it became necessary | to do so.
