AN EFFICIENT PRIVATE WATERWORKS SYSTEM
The Thomas D. Murphy company, of Red Oak, Ia., has installed a complicated and extensive waterworks plant in his establishment. It operates three large hydraulic elevators, supplies water for the plumbing system, furnishes a continual supply of fresh water for drinking purposes and operates the press for haling waste paper by hydraulic power. Two wells were first sunk, one at each end of the main building, and from these two water lifts pump continuouslv a supplv of water to a large galvanised tank of t.500-gals, capacitv sunk in the ground outside the building. The water in this tank is pumped by a triplex electric nump. a capacitv of about 1.200 srnls. per hour This is run hv n 5-borsepower electric motor and maintains a pressure of 00 to T20 lbs. on the entire waterworks svstem. Whenever the pressure sinks to the minimum a contact is made of the electric rheostat, and the pump immediatelv starts working A similar contact, when the maximum pressure is reached, stons the ppmn until the pressure again reaches the lowest point. The nressure for the three hvdranlic elevators is stored in each case in a large tank 10 ft high hv a ft. in diameter The air is compressed in tins tank under a pressure of about too lbs. per so. in . and. when the elevator valves are open, forces the water info the large evliridcr. which carries the elevatorplunger. Fach elevator, under the new svstem. lifts a weight of about 3.000 Iks The water used by the elevators is returned dircctlv to the storage tank, so that there is no loss from this source. This was not the case when city water was used, when it was discharged into fhr. sewer. The nnlv water-loss now is that which is discharged through the plumbing system. The drinking water apparatus, when installed, will he operated bv a water lift numning fresh water direct from the well, which will run continuous!’and he discharged into the cistern. Tims wilt he supplied on each floor perfectly pure and cool water, even in the hottest smmnnr days When the svstem is completed and in full operation, the comnapv will laentirely independent of the town waterworks, which will he relieved front supplying .an average of about 15.000 eals per day Connection will still he maintained with the citv norl-s however, so that in case of am accident or failure of spunkon the private system, the city water could he instantly used.
The bursting of the 20-in. pipe, the largest main of the citv waterworks system at Akron. O., shut off all water supply. and the city was at the mercy of fire for nearly twenty-four hours.
