 of the reservoir furnishing and faafalling a l6-inch pipe from our .g,t l6-inch main to reservoir and sutting the two idle filters that we -. in operation, which would in- crease our Altering capacity to 3,0OO,- 0ap eallons-the estimate Is Sll1 900. The second proposition would be to continue our 16-inch main from the 55,uer of Church and Pomfret streets f= he square above Bugbee's Corner. From this corner to the corner of Providence and Main streets. replacing fs. present 6-inch pipe with l2-ineh. This would benefit and increase the pressure along that business section a8 on account of the present s-inch mau running westerly on Providence erect the north end of the city would in. greatly benefited. This proposition T5v benefit Mechanics street t0 some estrnt on account of the added pres s5rt given by the higher altitude of the Hrw reservoir. but O what extent we ae unable to say. The estimated cost f this proposition Is S22, ,o00.
 Third Proposition
 The third proposition. which is quite important. would b. ta lay ten-inch main from the corner of Main and Providence streets to the junction of school and Mechanics e replace a six .aeh that has been lad for forty years years and on account of eorrosion can #ot be over five-ineh at present. This would give ample service to the north east side of the town and the foundry -ection. The estimated cost of this sec tfan. Sll .O00
 By installation of these three differ tat propositions the whole city would fe greatly benefited and We consider that the service would be adequate for many years to come.
 The total cost of the proposition as omitted is S150.500 These esti- ates We are informed by our engin- eef have been made very literally and .Hat if there were t3 exist any differ aaee in the actual cost of construction fHat 1t would be lower rather than FEhTT.

 Reservoir:
 Height of present tank. 2sl feet. Height of water in new reservoir feet
 Gain in head. 49 feet
 Gain in pressure. 21 pounds
 New pressure at Main and Union streets. l06 pounds.
 Capacity oi old tank. 2i0 900 gallons New pressure at Main and Provi- dcnee streets. 97 pounds. Domestic consumption (mid-day) 20, ,00O gh.p.
 Suppose pumps out of commission Domestic consumption would empty tank in 3 hours, 20 minutes.
 Three fire streams would empty tank in l hour, 36 minutes.
 But at the end of the first half hour the tank would have but thirty feet of water and streams would be growing weaker and weaker
 New reservoir would furnish ten standard streams in addition to domes- tic consumption for over nine hours and streams would be strong and ef feetiye during the ninth hour.
 Insurance Exchange obtained flow of 1920 g.p.h. at 67 pounds at corner of Main and Providence streets.
 Suppose 6-inch line from this point to corner of School and Mechanics streets be replaced with l0-inch e., 300 fcet).
 Friction loss for 1920 g.p.m. through 2500 feet l0-inch equals 2S feet or lz pounds.
 This would give 1920 g.p.m. at 3s pounds at School and Mechanic. streets equivalent to 5-240 gp.m streams at the present time which IS about 2-200 g.p.m. streams.
 The city should authorize the reser. Yoir and replacement on Providence and School streets at once.
 The replacement on Main street IS very desirable, but 1 feel that it can very well. if necessary. be delayed for time.
 By increasing the capacity of our filter plants to 3,00G.0 .000 gallons g.p.m with this capacity and the proposed reservoir, using the new 3,0OO,OOO gal lon pump, it will be possible to run the plant with one man. ] should not favor urging this expenditure, how ever. until the reservoir and pipe re- placements were cleaned up and out of the way.
