zens an opportunity to look over and
 study the figures and conditions rela-i
 tive to the increasing of the water SUD-
 ply before assembling in the city
 meeting Friday night the date having
 been changed from Wednesday night, the ceport of the engineers of the, Wa ter board is given below, having in addition to the report and figures on
 regarding the other possibilities, Stony
 brook and Gardner lake. The report
 come from the board of water com
 missioners for the purpose of inform ing the citizens and giving them the opportunity of knowing the facts and figures before the report is read at
 the city meeting. instead of trusting to
 the chance of the long report being heard, understood and remembered in
 the town hall long enough for the
 proper discussion of it. The report has been in course of preparation for some time, and is as follows: Report of Water Board. In order that the citizens may un derstand the present situation regard ing the extension of the water supply. the ft flowing facts and estimates are presented:
 The r. esant board of water commis- sionors completed it's organization and elerLed officers July g, 1910. There was on hand in Fairview reservoir at
 
 gallons of water out Of the four hun dred fifty millions which the full res- ervoir contains. This was one hundred thirty seven million gallons less than
 was on hand on the same day Of the previous year. and twenty million gall
 ions less than that on hand in any pre-
 ceding year at the same date since the reservoir was enlarged.
 At the highest point reached during the spring of 1910 the reservoir lacked one hundred forty-four million gallons of being full.
 On the 29th of July meters were in stalled on each of the two sixteen inch pipes leading from the reservoir, and the daily use of water was found to be about two and one-tenth million gall Ions.
 In the light of tlrase facts. the board
 were of the opinion that the time had come when it was their duty to take steps to procure an additional water supply.
 On the 5th day of August. within two weeks after it's organization. the pres snt board of water commissioners adopted Pease brook as source of additional supply. A large majority, at largely attended city meeting held
 Dec. 8. 1910, voted against authorizing the appropriation of money for devel- oping Pease brook as source of addi- tional water supply.
 At said last named city meeting data were presented regarding the develop ment of Gardner lake Stony brook and Jordan brook as sources of water sup ply.
 A former board of water commits sioners had adopted Stony brook as an additional source of supply, and their action had been disapproved by a largely attended city meeting. On the 18th day Of December the board adopted Jordan brook as a source of additional water supply. which action was approved by the court of common council Dec. goth. Each Source Has Advantages. The board of water commissioners are aware that no available source of water supply is better in every respect than every other source and that each source is in some respect better than others. They believe that it is much better for the city to adopt either tha II neither. They believe that Jordan brook will answer the c4y's needs for many years. and that there are excel lent opportunities for adding other sources in the immediate vicinity of Jordan brook when necessary. Report on Jordan Brook. The report of the engineers on Jor- dan brook was as follows: To the Board of Water Commissioners of the City of Norwich: At your request we have made pre- lminary surveys for estimating the ca pacity and cost of Jordan brook as a source of additional water supply for the city of Norwich.
 This brook is q branch of the Deep river which further down is called the Yantic river. Jordan river runs across the Colchester turnpike in the town Of Lebanon about one and one-half miles westerly from the Harrison paper mill. | ,fxsp-N .sJ IF one and three quarters square miles, extending from Goshen Hill to good dam site about half mile northerly from the Colchester turnpike. The ground above the dam site is free from deep mud and well suited for a reservoir.
 The bed of the brook at the dam site is about three hundred and four (304) feet above mean tide, and about eighty-ffve (85) feet above the bottom of Fairview reservoir.
 A dam with it's rollway thirty-four (34) feet above the bed of the brook would flow ninety (90) acres and store three hundred thirty (330) million gal 1 Ions of water. the surface of which would be ninety (9a) feet above high water of Fairview reservoir This | watershed and storage would add twelve CPD hundred thousand gallons daily dependable water to our present supply. This yield can be increased to any needed extent by adding the flow Of adjacent tributaries of Deep river. or by taking water by gravity from Daep river.
 A twenty inch pipe is recommended in order to give capacity to take the waters of such adjacent watersheds when necessary. This pipe while new would deliver about four million gall ! Ions daily to our system. We estimate the cost of this addi- tion to our supply including land and
 rights of way but excluding water rights. at $290,000.
 All of which is respectfully submit ted.
 CHANDLER & PALMER, Civil Engineers. Norwich. Dec. 19, 1910. In order that the relation of our 1 present sources to any additional sources may be plain, the following | facts are given:
 Present and Additional Sources. Our present supply consists of 2.3 l square miles of watershed of which 1.55 1 square miles is at Meadow brook and l three quarters of d square mile at 1 FairVieW The watersheds are con- 1 nected by . tive ty-fJur inch pipe hay l ing carrying capacity under average | conditions of about five million gallons daily. There is sufficient storage ca- pacity at Meadow brook to hold storm | water until the pipe can carry it to 1 Fairview, so the two watersheds may l De treated as one. The sapacity of 1 Fairview reservoi, is 450 million gal lens. The surface of full reservoir is
