PETONE DRAINAGE

SEWERAGE SCHEME TO BE COMMENCED REPORT BY THE ENGINEEB. A special meeting of the Petone Borough Council was held last evening ! for the purpose of considering the report of the engineer (Mr. R. Fox) on the sewerage scheme, and also deciding as to what steps will be taken in regard to a loan of £9000 f6r financing the commencement of the work. There were present: The Mayor (Mr. J. W. M'Ewan) and Councillors Piper, .True* man, Burridge, Lodder, Cox, Brockel' bank, List, and Short. The borough engineer stated that the plans were in such a state that they could be almost immediately submitted to any outsido expert the council might select. In the course of a detailed report Mr. Fox stated that the septic tank and details, outfall sewer manholes and lampholes, has been designed and drawn. The levels at street intersections, etc., has been taken and the streets chained. The township was divided intp four zones or sections, 'each having its own pumping station. No. 1 section served the area, lying between Jessie-street on the east and Bolton-street on • the west, and bounded by the stop bank on the north side of Pattie-street, provision having been made to reticulate that portion north of Heretaunga-street when the roads were formed ; No. 2 section embraced the arear between Bolton and yictofht streets, and from the Esplanade to Jackson-street, in< eluding Elizabeth-street, Gear-street, and Petone-avenue j No. 3 section took in that portion between Victoriastreet and the Hutt-road, including the Woollen" Mills, Railway Station, and a portion of Jackson-street ; and No. .4 section covered that portion of the borough from Jackson-street to White'sline, and. from Britannia-street to Riddler's-crescent, The' scheme was on the intercepting' plan, the main sewers being constructed along the Esplanade and serving their separate sections. The site ot the septic tank was a few chains north of the- sanitary depot, and the outfall sewer discharge into the river at a point almost due east of the depot, The tanks (in duplicate) had a capacity of 210,000 gallons, this being equivalent to a per capita' rate of 35 gallons for a population of 12,000, giving a twelve hour flow through the tank. The approxi' mate cost of the tank and outfall sewer was £2750. From pumping station No. 1 the whole sewerage of the borough would* get its final lift to the septic tank. Its position would be upon a section facing the Esplanade, between Oriental and William streets. The approximate cost, of this station would be £1000. The pumping station for No. 2 area would be upon the Esplanade, 166 ft west of Nelson-street and about 70ft from the • building line.- Thelapproximate 'cost of this station would be £460. The station for pumping section No. 3 would be upon the Esplanade at Nevisstreet, ana the wells (in duplicate) ( would have a capacity of about 2260 gal' lons, The station for No. 4 was in' Re-gent-street, at the north end of Sydney* street, and ifc would be constructed pimilar to the station of No. 3 section. Stations No. 2, 3, aiid 4 would be Underground. ,If the council decided to commence a portion of the Work shorfly, it would be ' necessary *■ tto gefc a certain amount of 'plant, and to order sufficient pipes to reticulate the area to be started upon. He would rocommend building the. septic tanlfi constructing the outfall ■ and delivery 'mainß, the main pumping station*; andHne, maifi-'interceptiniv sewer <along the Esplanade," *and reticulating the most .thickly populated pprtioii of the borough, namely No. 2 Bection. v He thought -a contract should at onco be let for the earthenware pipes. The pipes required for No. 2 section would be as follow :— 6in pipes, 69E)6 : 9in, 1734 ; 12in, 1616; 15in 78; 18in 35; 4in' pipes for house connections, 3000. The plant, timber, et<;.. required to carry out the work would approximately cost £675.

He had not had sufficient time to go into thp ijoatter thoroughly. After the scheme had 'been approved, it, would be necessary to let a contract for the supply and delivery of cast-iron pipes and •fittings. It was intended to utilise the engines ( at J,he .pumping station of the eastern 'drainage system td run the generators which would supply . the power to the motors.- As all the motors and 3 0urrip3 wouTd be in duplicate, it Would be advisable to generate sufficient power at the main station, so that they could, if required, be run together^ ' • -The Mayor, in explaining the objects of the meeting, ,3airf that an offer to loan the council £9000 at 4||. per cent, was. before councillors. In view §f this) he liad asked the engineer to prepare a report showing the progress made by the plans, and-this was now before the council. He proposed asking councillors to Consider the question of printing debentures which could be issued from time to time upon such terms as might be agreed upon. He also intended to ask the council to consider the question of calling tenders for pipes. Replying to a question the Mayor stated that the plant required for the first section would cost £12,665. In regard to the question of submitting the- plans to an outside expert, . he considered that this matter should be gone into in committee. j Councillor Piper moved that the plans be submitted to Mr. Cnthbert, drainage engineer, of Christchurch. The council then went into committee, when it was decided to take advantage of the offer for the £9000 loan; to submit the plans and report to 'Mr Cuthbert, and to call for tenders for the supply of earthenware and cast-iron pipes.
