CITY ABLE TO FURNISH lloHT.
(Fssa rsiaay's Dsily)

install an electric light service in con junction with it's pumping plant, was made evident to the party of citizens who with Mayor Goldwater and mem. bers of the Council, visited Del Rio yesterday as the guests of Frank NJ. Murphy, who provided n coach attach ed to his private car, for the trip.
 It was n congeniai crowd that left Prescott at 2 o'clock, and the journey to Del Rio was n pleasant one, the run only consuming an hour. Arriving at the plant, Superintendent C. c. Glass showed the visitors through the powerhousc, and explained the various features of the equipment. The ma chincry was in fine order, and running smoothly, and the visitors were deeply interested in the impressive mechanism that is delivering water into Prescott at the rate of 2i,0OO gallons an hour.
 or the greatest interest to the party. however. was the big dynamo and the electrical equipment. This generates the power that is transmitted to Willow creek station, where . motor lifts the water to the city reservoir, thereby reducing the pressure on the pipe system.
 The indicators on the switchboard showed that only 10 amperes were used for this work. while the actual capacity Is 65 amperes, and with an overload can be run up to so amperes. IL is this surplus power that 1t is proposed to utilize for n municipal lighting plant. It is sufficient for 1000 incandesccnts and 60 arc lights, and can he increased to 6,OO0 incandesccnts simply by shut. ting down the new pump and using the duplicate plant that heretofore has been employed.
 The city owns n wonderful and seem. ingly inexhaustible supply at Del Rio. There are two wells. which are filed with water to the surface, nnd there are thousands of gallons going to waste. The water has been analysed and de. termincd to be as pure as any in the United States.
 The equipment of the new water sys- tenn consists of the following apparatus:
 The boiler is of the water tube type manufactured by the Babcock & Will cox company, and is guaranteed to eva poratc 5000 pounds of water per houI into steam at 600 pounds pressure, ear rying 1902 supcrhcat. Under ,hes' steam conditions this boiler will de liver 400 h. p. to modern compound con
 densing engine. The new engine II known commercially as the Fleming |
 valve tandem compound condensini Corliss engine, having n maximum ea pncity nj 3s cut off on valves will 200 pounds admission steam pressure and %" vacuum of $50 horse power The engine is a very substantial piece of machinery weighing 32 tons, an' mounted on solid concrete foundation 8 feet deep.
 The valve motion on this engine 1 the result of years of study and experi
 ment resulting in . valve construction which will cause the engine to delive its rated capacity on the 'eonsumptio
 of I2 pounds of steam per horse pow CT hour.
 The shaft of this engine ia directl connected to the driving Pinion of th . Gould horizontal tripiex. double ac' U ing pump. which ia very substar . tiai piece of machinery in itself, th
 shipping weight being 20 tons. Tn engine and pump being mounted on th 7 same foundation, makes a very con
 pact and substantial unit, operatin
 apparently without any effort at V
 bration.
 The present system of pumping is
 deliver the water to an auxiliary sti '' ton located at Willow creek, on th
 main pipe line, and by the use (
 electric driven pumps in this statiol '. make second lift, thereby reiicvin e the pressure on the main pipe line fro ,r Willow creek to Del Rio (i5 miles) h d 26O pounds per square inch. Und' n this increased delivery of wat' ,- through the pipe line the total pressu' '. of the delivery is 7lO pounds, of whi' 'e the Del Rio pump delivers against 4 ,r pounds and the auxiliary station 2 'r pounds.
 a. The Willow creek auxiliary static is is operated on the remote control sy ss tenn, it being entirely under the contr
 of the Del Rio power house.
 The dynamo is what is commercial D known ns a Westinghouse 3-phase '
 volving field dynamo, having a cap
 citv of 1S6 amDeres At o200 volts
