TRAMWAYS AND ELECTRIC LIGHT.
INTERESTING REPORTS. Mr. R. H. Bartley will report to tonight's meeting of tilt Borough Council as follows. The tramway report for September are as under: Main Route.—Mileage run, 12,9023; passengers carried, 75,404; revenue per ear mile, 10.3d; passengers per car mile, 5.7; average fare per passenger, 1.7 d; total fares, £552 14s. Morley Street Route.—Mileage run, 2588!; passengers carried, 13,702; revenue per car mile, 7.Ail; passengers per car mile, 5.8; average fare per passenger, 1.5 d; total fares, £7O 8s 7d. Combined Routes —Mileage run, 15,Hf)H; passengers carried, 80,286; revenue per car mile, O.ld; passengers per car mile, 5.1; average fare per passenger, l.Od; total fares £032 2s 7d. The returns for the month show an increase of £37 lis 4d on the previous month's working and 3804 additional passengers were carried. The service has been maintained in accordance with the time-table and •without interruption of any kind. The repairs and maintenance to the equipment are quite normal ai:d the plant is working smoothly. ELECTRIC LIGHT DEPARTMENT. An uninterrupted service has been maintained throughout the mouth, and the plant- Iris given very little trouble. The sub-station machinery is working well and the storage battery is in good condition. , Ee tests taken at powerhouse 011 September 14, 1016: As explained in my report dated August 31. 1016, there were certain matters which I was compelled to accept not having carried out any practical tests personally. I took the opportunity 011 the above date of making some tests that should be useful for future reference, and save considerable time in later power station calculations. The chief objects of the tests were: (1) To obtain the absolute maximum capability of the existing tunnel with reference to the discharge of water in cubic feet per minute under the head created by the existing dam. (2) To ascertain the effect 011 head of water in the dam relative to the discharge from tunnel and inlet from river. (3) To ascertain the head lost in delivery pipes between forebay and power station. (4) To ascertain the maximum amount of power-cap-able of being generated at power house with the tunnel delivering at its maximum. also available head. (5) To ascertain the reasons as to why certain nia-i-hines as per previous record would not work up to full load and overload. (6) To compare record of the test with those figures given in my report, which were calculated.
Procedure.—The intake gates at the Waiwakaiho river were open six inches. The water in dam flowing over spillwav three or four inches. The water level in forebav normal, showing 126 feet head at powerhouse. Four of the machines at the powerhouse were arranged on artificial loads, the remaining one supplying the town load. The artificial load was increased until the water in the forebav dropped to the level of the top of the tunnel, and the load was retained at this. The object of this was to have the tunnel discharged only as against atmospheric pressure and this at the maximum velocity The water bein;; discha'ged from the turbines into the tail race was then measured and represents the greatest eli'ort that can be executed under existing conditions, beini 4700 cubic feet p.r minute. During this period the water level in the dam dropped Ift Oin. meaning :i loss of Ift Oin head between dam and forebay. Hdwever, it is not such as to materially affect the result of the te-t and was due to the intake gate not being opened sufficiently. The gate opening was increased and Hie water in the dam immediately started to make.
KesuHs.—(U Mavimum capacity of lunne!. 47(10 cubic feet per minute. (2) lloiul in dam can lie maintained with tunnel <lisfliav«in<t at its maximum, (.1) Head loss when taking maximum supply at tunnel, 13 feet. (4) Maximum nower generated at power station, 070 k.w. or 80.1 li.p. (5) One of the 250 k'.v.a. machines which 1 v.'as under the impression would not stand up to full load, handled full load and approximately i"i per cent, overload. The other machine in question is Xo. 4. and time would not permit the continuing or the test of thi-' owp> v (f>) The differences as between the results calculated and by practical test is very small in comparison and it must he very clearly seen now that the limit is 8!)3-h.p. under the existing hydraulic conditions. COMMTTTF !"!ICCOMMEND.4TTONB, Electric and tramway.- committea resoiiiiv.'-.ndaiionsi—Tliat upon Mr,
H. Martin agreeing to contribute the sum of £ls towards the cost and guaranteeing an annua] net revenue of not less than £8 per annum the electrical engineer be authorised to extend the electric light mains to enable his, property to be connected (estimated cost £.i'2 10s); subject to the works committee agreeing to pay for the extra street light the alterations to the elecrie lighting applied for by the Kawaroa Park Society be carried out (estimated cost £5); that the electrical and tramways engineer be authorised to purchase the following meters for house services, in two deliveries if possible: 200 Samp., oO Samp., 50 lOamp., 20 15amp., 20 25amp. The electrical and tramways engineer was instructed to submit a report, in regard to ail improved system of charges for electric lighting and power; that the electrical and tramway* engineer be authorised to sell the two 45-k.w. machines at Ihe •power-house at the following prices: £450 for each complete set, if the alternators are sold separately £3OO each, delivery to be given after the new machine has been installed; that the consulting engineer be requested to submit plans for double windows for the machine room at the substation as suggested bv him, together with an estimate of the cost; that the reference to the Morley street extension he received: that subject to the conditions set out in the engineer's letter of the 13th inst., a "request" stop for the tramcars be made at the loop just past the Breakwater Hotel; that the question of removing building debris from under the substation building be referred to the electrical and tramways engineer to deal with; that the letter from the Public Works Department with reference to the proposed power line to the Breakwater be referred to the electrical and tramways engineer to confer with the Post and Telegraph Department; that tramway construction material to the value of £570 17s (id as shown 011 the list submitted be taken over from the contractors (Messrs. Greenshields and Co). The request of the Park Fete Committee (Soldiers' Comforts Week) to have the band rotunda at the Pukekura Park connected with the electric lighting installation at their cost was acceded to and the electrical and tramways engineer was authorised to grant any assistance within his power in arranging for the illumination of the stalls, etc.; that the terms of the contract for right to advertise 011 doors in the tram cars as submitted by Messrs. Whittomc, Stevenson and Co.. Ltd., be approved; that the electrical and tramways engineer be authorised to extend the electric light mains in Paynter's Lane to enable Mr. Balharry's house to be connected (estimated cost £ls 2s 4d).
