Some pipe extension also will, undoubtedly, be request- ed in new streets.
We therefore recommend an appropriation of $15,- 000.00 for construction and the usual appropriation of $28,000.00 for maintenance, including a continuation of the metering program.
Respectfully submitted,
WILLIAM R. MORTON, Chairman, JOHN H. DAMON, JOHN L. MORTON, FRANK D. BARTLETT, RICHARD T. ELDRIDGE,

During the past year the principal activity of the De- partment consisted in completing the construction of the new high service system and putting it in operation.
An appropriation of $45,000.00 was made for this work in March 1926 but there was some delay in beginning construction, due to the fact that the laid out way in which it was desirable to lay the pipe was not graded until 1928.
There was 3,000 ft. of 8" pipe laid in 1928 and the balance of about 7,000 ft. of 8" was laid in 1929. This line connects with an existing 6" line at Liberty Street. There are at present 37 services on this system and 10 hydrants to furnish fire protection.
A small brick pumping station was built on Billington Street near Deep Water Bridge. This station contains two Fairbanks-Morse 200 GPM. pumps, operated by two
Plymouth Six

15 HP. motors, also a recording Venturi meter register as well as a recording pressure gauge and volt meter. The pumps are arranged for either automatic or manual control. Normally, they are on the automatic control and are stopped and started by an electrical device when the water in the standpipe reaches a pre-determined level.
The water supplied to the pumps is taken from a 14" low service main on Billington Street by means of a 6" connection ; a second 6" connection for use in an emer- gency has been made with the 16" old high service main. The suction lines to the pumps have been so arranged that the pumps may be operated separately, or together, and either pump can draft its water from either main.
The new station has been placed in charge of the engineers at the old station.
PROPOSED IMPROVEMENTS
During periods of heavy summer draft, complaints have been made of poor pressure at some points on the old high service system that it would not be feasible to sup- ply from the new high service. One of these sections is the high ground at the top of the hill at Cherry Street and Savery Avenue. The Plymouth Country Club, having enlarged its Golf Course and extended and renewed the piping system used for watering greens, has requested some improvements in the distribution system in its vicinity.
The situation could be improved in both these local- ities by the erection of two standpipes, one on Cherry Street and one on Manomet Road about 750 ft. south of its junction with Warren Avenue.
In order to improve the conditions on Doten Road, which borders the Golf Course on the south-westerly side, it would be necessary to replace about 1,400 ft. of 2" pipe, now in that road, with 6" pipe.
-83-
Several pipe extensions will undoubtedly be requested during the coming year on new street developments. An appropriation of $15,000.00 for construction is suggested if the new work mentioned above is to be carried out.
HYDRANTS
There have been five new hydrants added during the year, including those set on the new high service system. They have all been painted during the year and carefully inspected and are in good condition.
GATES
The regular semi-annual inspection of the gate valves has been continued in 1929. The inspection consists in closing and opening the gate to make sure it is in satis- factory condition.
SAVERY LANE
A 2" galvanized line on Savery Lane was replaced in 1929 with 6" cement lined cast iron pipe. A new hydrant was set on this line about midway between Standish Avenue and Court Street. This new line will improve the circulation in this section and the additional hydrant will furnish better fire protection.
POND HEIGHT AND STORAGE
Plate I is the usual chart showing pond heights and storage fluctuations for the past ten years in Great and Little South Ponds. At the beginning of the year 1929 there was approximately six hundred million gallons in storage which was increased to about seven hundred and fifty million gallons on June 1st due to heavy spring rain- fall. The storage volume then decreased gradually until at the end of the year it was approximately six hundred and fifteen million gallons.

CONSUMPTION
Plate II shows graphically the average daily con- sumption on the old high service system and the low service system. The inset in the upper right hand corner of the plate gives the same information regarding the new high service system.
The average daily low service consumption was 387,000 gallons, compared to 549,000 gallons in 1928, a decrease of 162,000 gallons daily. The average daily high service consumption was 818,000 gallons, compared to 788,000 gallons in 1928, an increase of 30,000 gallons daily. The average daily total consumption for the year was, 1,235,- 000 gallons, compared to 1,337,000 gallons in 1928, a decrease of 102,000 gallons.
The pumping records shown on the following sheet gives in some detail the records kept at the pumping station during the year.
METERS
There were 119 meters set during the year, making the total now in use 1,905, or 63.5%, of all services are now metered.
ANALYSES OF WATER
The State Department of Health has made the usual analyses of samples of water from our supply during the year 1929 and copies of these are on file in the office of the Superintendent.

REPORT ON PROPOSED WATER SYSTEM FOR MANOMET
The Water Commissioners submit herewith their re- port on a proposed water supply system for Manomet, as prepared by the Superintendent, and in accordance with the following vote passed at the regular Town Meet- ing held March 23, 1929.
"That the Town appropriate the sum of $1,500.00 to cover the expense of a preliminary survey and cost esti- mate for the proposed public water supply system for Manomet. Said sum to be expended under the direction of the Water Commissioners."
PLAN
The plan accompanying this report has been compiled from several individual surveys and while it has been necessary to sketch in some of the roads in the new de- velopments the plan is sufficiently accurate to use as a basis for a preliminary cost estimate. All elevations shown are taken from a plan furnished by the Massa- chusetts Department of Public Works and are elevations above mean low water. The houses on the plan are in- dicated by square dots and the hydrants by circles.
An examination of the plan would appear to indicate that there are three sections to be supplied, viz :
(a) White Horse Beach and Priscilla Beach,
(b) Manomet Point development near Life Saving Sta- tion,
(c) Settlement at Manomet Bluffs.
In addition, there would be scattered houses along the pipe lines leading to these sections and possible exten- sions on Beaver Dam Road and Brook Road.
WELLS
One of the first problems was to locate a source of water supply, and to study this, test wells were driven in two localities. The first well driven was on the south side of the Pine Hills on the west side of the State High-
-87-
way. This well was carried to a depth of about 57 ft. Some stones were encountered and then a dense stratum that yielded only a small supply of water. This well was examined by an engineer from the State Department of Health and acting upon his advice, further driving in this location was discontinued, and two test wells were driven on the land of Samuel Stephens at Fresh Pond. One well about 75 ft. from the shore and another deeper one about 150 ft. from the shore.
The deepest of these wells at Fresh Pond was 85 ft. and water rose in this well to within 15 ft. of the sur- face of the ground. The yield from this well was at the rate of about ten gallons per minute. Samples of this. water were analyzed by the State Department of Health and found satisfactory, as indicated in the letter from that Board and which follows this report.
The Commissioners are satisfied that an adequate sup- ply of water of good quality can be obtained from a series of driven wells in the locality where this test well was driven.
DISTRIBUTION SYSTEM
It is proposed to erect two 200,000 gallon standpipes on this system, as shown on the accompanying map. One of these to be on the hill above the pumping station near Fresh Pond and the other on the bluff near the ocean at the northerly end of the Priscilla Beach development.
The distribution system contemplates a 10" main along the State Highway from Fresh Pond to White Horse Road. Then, 8" mains down White Horse Road to the settlements at Priscilla Beach and White Horse, another 8" line down the Point Road to Life Saving Station and an encircling 8" main down Samoset Avenue, southerly along the bluff, to connect with a 10" main on the State Highway near Fresh Pond. Also, cross connecting 6" lines in all streets where the houses are sufficiently numerous to warrant it. It is believed that the size of
-88-
mains and standpipe capacities, as indicated above, are ample to allow for future growth for as long a period in the future as we may reasonably be expected to pro- vide for.
In order to study the adequacy of the system for fire protection, three locations have been selected and the friction loss calculated for the delivery at these points of 600 gallons per minute equivalent to three good fire steams. At the White Horse Post Office on White Horse Road the total friction loss with a delivery of 600 gallons per minute, as mentioned above, would be approximately 51/2 lbs. On Taylor Avenue, at the Brook, this loss would be approximately 20 lbs. and on the Point Road, near the Life Saving Station, approximately 271/2 lbs.
HOUSES AT MANOMET
The table below shows the approximate number of houses that might be possible water takers.
White Horse 170

Priscilla Beach 29
Point Section
50
State Road 52
Manomet Bluff 109

Total 528
We think the 94 houses shown in the Squatter Colony can be disregarded as far as individual house services are concerned. This colony is on a part of White Horse Beach, south of the brook, where no attempt has been made to lay out streets or ways and the houses are simply clustered together. The only suggestion we have to make in regard to supplying water to this section is to put in a pipe across the brook with a metered connection and require some responsible group of house owners in the

Squatter Colony to be responsible for all water passing through the meter.
Excluding the 94 houses in the Squatter Colony leaves 434 houses as possible future takers. We believe a liberal estimate of consumption would be 400 gallons per service per day to allow for actual use and unavoidable leakage in mains. This would make a total daily consumption of approximately 175,000 gallons to be provided and al- though it is pretty certain that not all the present houses would take water the first year it may be fairly assumed that within a period of five years most of them would pre- fer to take Town water. In this connection it may be noted that only 118 people have signed an agreement to take water at a rate of $25.00 per year.
MANOMET WATER COMPANY
The summer colony at White Horse Beach has about 170 houses and about 105 of these are at present supplied by a small water system owned by Clarence Randall of Whitman. The supply consists of a small motor driven pump getting its water from three 21/2" wells. The dis- tribution system contains approximately two miles of 11/2" and 2" galvanized pipe, laid in a trench not more than two feet deep, and a wooden standpipe of 10,000 gal- lons capacity. Mr. Randall estimated that the average daily consumption through the summer was about 15,000 gallons. The system probably serves the community rea- sonably well for domestic use but has no value for fire protection. Since Mr. Randall started his system some of the streets in which his pipes are laid have been laid out by the Town as public ways, and in these laid out streets the Town would have the right to lay pipe. The Town has the right to lay water pipes in private ways provided the owner or owners of the fee comply with the provisions of Ch. 41 Sec. 74 of the G. L. and provided further that the owner or owners of the fee to said priv- ate way could and would grant to the town an easement to lay said pipe.

INSURANCE
A study has also been made of the reduction in insur- ance premium that would be possible if this system was built, substantially in accordance with the accompanying plan, even if no fire company or pumping equipment was located in Manomet. A conservative estimate was $2,- 000.00 annual saving in insurance premium.
ASSESSED VALUES
A study has been made of the assessed value of all the real estate within the limits of the area served by the proposed water supply system.
The assessed value of the buildings is $963,865.00
land, 381,385.00
Total, $1,345,250.00
With an adequate water system, furnishing an ample supply of good water for domestic use and fire protection, the value of all the real estate within the limits of such a system is materially enhanced. On the assumption that the increased value of the real estate would be as much as 15% and the further assumption that the tax rate would be $25.00 per thousand, the following calculations show the annual increase in revenue that would accrue in the tax levy.
Total assessed value, .. . $1,345,250.00 200,000.00 (approximate) 15%
With a tax rate of $25.00 per thousand the annual in- crease would be $5,000.

FINANCING THE PROJECT
The estimated construction cost of the system is $162,- 000.00 and it is our understanding that if an appropri- ation was made to do this work, approximately $6,000.00 would have to be raised from the current tax levy, and the balance might be raised by a fifteen year bond issue of $156,000.00 at 4%, with an annual payment on the principal of $10,400.00.
Table II, which follows, has been arranged to show the annual bond and interest payments that would be required to liquidate the above bond issue of $156,000.00.

The following, Table III, shows the estimated annual total cost and cost per consumer, of operation of the sys- tem, figuring power, labor and depreciation.
The power cost is based on the assumption that we start with 200 takers with a daily use of 400 gallons per taker, which is equivalent to 2,400,000 gallons per month.
The total head to be pumped against is approximately the same as that at the new high service station on Bil- lington Street and the power is the same. The K.W.H. used at the Manomet station would thus be proportional to the K.W.H. at the Billington Street Station, and the annual power cost has been figured on this basis.
