The plan of Mr. Janin, C. E., waterworks superintendent, Montreal, for an increased supply of better water, as well as a greatly increased water power for pumping the drinking water, with estimated cost, has been submitted to two experts, John Kennedy, C. E., consulting engineer of the Montreal harbour commissioners and Ernest Marceau, C. E. Their report is given be low as follows: “The essential features of Mr. Janin’s project, as set forth in the information supplied to us by him, are: (I) The construction of a closed conduit along the north side of the aqueduct from the pumping station to the bank of the St. Lawrence, just above the entrance works of the aqueduct and its extension out into the river to an intake point, where it will be supplied by St. Lawrence water unmixed with shore water and water from the Ottawa river. The shore part of the conduit is to be of watertight concrete construction, and about 57 sq. ft. area of internal section and to have a fall of x in 3,000. (2) The enlargement of the aqueduct from its intake at the river to the pumping station to a cross-sectional area of not less than 1,008 ft. below the under surface of the ice at low water, which is assumed to be at elevation 33 ft. above waterworks datum at the entrance, and having a fall of 1 in 8,333. (3) The remodeling and increase of the hydraulic power pumping machinery at the pumping station, to a capacity of at least 50,000,000 imperial gals, per twenty-four hours and connections for supplying the pumps from the new conduit, also connections with the pumping mains leading to the city, and the rearrangement of the steam power pumping machinery, to conform to the new conditions. (4) The enlargement of the tailracc to the capacity necessary for the discharge of the water from the enlarged aqueduct. (5) Wells, waste-gates and other works requisite for the proper working of the enlarged aqueduct and increased pumping machinery. We are of the opinion that Mr. Janin’s plan as thus outlined is entirely feasible, and that it is an excellent one for improving the quality, increasing the quantity and reducing the cost of the city’s water supply. We are of opinion that the projected works will supply waterpower to pump to the city 50,000,000 imperial gals, per day of twenty-four hours, under the most unfavorable condi lions— that is. at the lowest recorded stage of the river in winter and when the aqueduct is covered with ice, which is the capacity stated in Mr. Janin’s reports. Mr. Janin, in his report of 18th March, 1907, states that the enlarged aqueduct will develop 5.000 horsepower in summer; we are of the opinion that this estimate of power is correct for the most unfavorable summer condition that is. the etdarged aqueduct will furnish water to develop 5,000 effective horsepower at the waterwheels, when the river, at the entrance of the aqueduct is at its lowest recorded depth of 35 85 above datum. Under ordinary summer conditions that is, with higher water, the power which can be developed will, of course, exceed 5,ocx) horsepower. We have checked the estimate of cost of the conduit from the river bank at the intake to the well at the pumping station, and we are of the opinion that Mr. Janin’s estimate of $660,000, is correct. The estimate for the other items will be dealt with in a further report, after the necessary details have been prepared and furnished us. The details of the works, at the entrance of the aqueduct and the intake of the conduit are not yet fully worked out; but, from the fact that the position of the present aqueduct intake is a very favorable one, and that no trouble has ever been experienced from frazil entering it, we are of opinion, that the works can 1K‘ so designed and built, that their operation will not be seriouslv interfered with by frazil.

The existing plant can be modified and enlarged, without its operations being interfered with. The present open aqueduct is 40 ft. wide by 8 ft. deep for drinking purposes. As it now is. dust and dirt get into it; dogs are swum, and boys even bathe in it, although each practice is forbidden. The watercourse, after the proposed enlargement, will be 140 ft. wide by 14 deep. The whole volume of water will be used for pumping pur poses only, doing away with both steam and electric pumps. The proposed covered conduit for drinking purposes only will be 10 ft, in diameter, with a capacity of 50.000.000 gals.
