SEWERAGE.

SCHEME FOR REDCLIFIS. RESIDENTS APPROVE. About seventy Bcdeliff* ratepayers met in the Community Hail last evenir.g to consider a proposal to go ahead, with the Kedcliffs sewerage loan p^. The Mayor o: Suinner v ilr * U> Nicholson}. who presided, said that the attendance showed that the rt.sr en recognised the necessity oi the sewerage loun. Various sehemes had been put forward, bur until rceentlj nothing to lit the pockets of Bedcliffa residents had been found. The Borough Council had made enquiries fcud found thai an oxidising system .would I'C suitable for the district, and on behalf of the Council he wished to put forward the scheme. A low-lying settlement would become unhealthy unless there was a proper sanitation system. .Some of the fj£l areas in the district were below eealevcl. and special measures to suit them would have to be adopted. It was time that such practices as allowing slops and dish-water to flow out into sections were put a stop to. (Applause.) The cost of the scheme, he hoped the residents would agree, was a reasonao.e one. I'lie reason why three tanks would used, instead of a central system, was an economic one. Tho Council had made temporary arrangements wiUi tlie bunk until the advances ot 3-0000 per vcar from the Government would be received. The system to be put forward was in successful operation in Australia and New Zealand. Plants j had been in operation at Picton, Papa- j nui, Cashmere Hills, and Mount Ilea- j sunt. and they were all working wet). 1 He hoped residents would give the . Council credit . for doing its best ior > the health and prosperity of the district. ] He wished to give special credit to j Crs. 11. W. Harris, E. Peek, and C. , H.Eoswell for tho part they had taken ; in forwarding the scheme. _ The cost to ; the owner of a section with an uunu- • proved value of £-70 -would be I.jS ou. ; which amount he now paid for the pre- , sent system, plus a- flat-rate oi lis fed I for water. " j The report submitted by il»c consulting engineers, Messrs Hanmer and Barker, stated that the scheme provided ..or the laying of 3S4£ chains or sewers .and the building of three Neilson tanks, ■with tho necessary effluent-holding tank?, pumps, and motors. It was proposed to lay a nine-iuch mam from i part-wav up Augustus street and from William street, in the Christchurch- . Sumner road, to No. 11 tank (rifle , range), all the other sewers being sixinch ones. Cast-iron pipes were allowed j for in tho whole of tho Clifton reticu- : lation and for several chains in tho j Christchurch-Sumner road and Estuary | road, where the cover was not sufli- j cicnt for ordinary sewers. Excepting for Estuary road and from Pratt street , to the foot of Clifton in the Clirist-church-Sumnter road, it was proposed to run the sewers in the centre of the streets. On account of the doubtful nature of the soil at any depth greater than a few feet, they had endeavoured to keep all sewers up to the absolute limit, which necessitated tho use ot castiron pipes in two places. Along Estuary road, where water would probably bo encountered badly, tlie use of castiron pipes or else the setting of the ordinary pipes in concrete necessary." It was possible,- too; that if rock , were encountered near ;the cutting in the Council yard cast-iron pipes might have to be used. Tho tanks would have to be some depth, and if water wctc eiicouutered, the cost would bo increased. Ample provision, was allowed for tho Containing of the effluent before pumping, to ensure safety if the automati electric pumping failed and it was necessary to use a stand-by motor. One pumping a day should sufoce 111. tanks, but two per day might be necessary for No. 11. Rotors of from 1.5 h.p to 2.0 h.p. should give ample power for pumping with centrifugal pumps. Owing to th closed nature of the <iistrict, of sewerage was not likely to be gre.it but allowance had been made for a ultimate increase of 60 per cent. * revision was made for the avoidance ox

creeks and culverts. , It is estimated that the cost of the work, including cost of floating loan and an allowance of M> VV ecu • for contingencies, will be £13,00 . Cr H. W. Harris explained that me system of tanks might be called »onKic » It was claimed that no sulphuretted hydrogen (or '' r ?" cn gas") was formed in the tanks owmfe ( to the admission of osygen. The efflu-; cnt was harmless. , ! The Mayor said he had a g^ from Professor Neilson and his firm that he would keep the tanks m perfect Hon. J. Barr, M.L.C., said tho Picton authorities had first- g°" e nl the new system, and it bad P^ ed . undoubted success there. larding the Mt. Pleasant scheme, lie said tha a Heathcote County n cll!o ' ® told him that the effluent P® ly harmless and colourless Jnrt® tered the estuary and at the pre time water coming from s wash tubs in some residences went . either into tho ground or into the gu ters. in which latter case r oull . sometimes a quarrel beiwcen tbo Co cil and the resident , Tlus would be overcome entirely bj tem, and residents would be practically the same footing a church -people. He could not agree with the' Mayor that made healthier .by the tea there was no more healthy place i New Zealand. _ (Applause.)

wise residents ■ would be at the mere} of contractors: Tho Mayor said that materials would be indented and all -the work would bo carried out by tho Council, under the superintendence of the foreman. (Applause.) At a rough estimate it would be eighteen months before the whole or the-work was completed, provided the loan was carried at once Asked what was to be done for residents of McCormack's 13ay, the Mayor said that it would be unfair to saddle the residents of Redelifis with a few verv expensive connexions. McCormack's Bay people might get their own reticulation area and have their own tank. Mr Barr explained that the now system made provision for 500 houses and also for the hilly country. A motion thanking the Mayor and Councillors for their work was carried by acclamation.
