THE SMITH STREET SEWER, commences at the eastern limit of Brompton Road, proceeds westward along the Brompton Road into the Fulham Road, and passes from the parish at Keppell Street. This Sewer is the outlet for the adjacent Sewers on the North side of the Brompton Road; and of Grove Place, Michael’s Grove, and Brompton Crescent, on the South Side. * * * * * A portion of the Kensington branch of the Counter Creek sewer, taking the drainage from Notting-hill, east of the Turnpike-gate, Uxbridge, and other streets and places in that locality, passing through a part of St. Margaret’s, Westminster, to Young-street, receiving the drainage from several streets and places in the town proper, and also the whole of the drainage from Kensington New-town. At the Workhouse the sewer is 5 ft. 6 in. by 3 ft. 6 in., and here terminates; the sewage matter, being conveyed from thence along the Pembroke-road, by an 18 in. glazed stoneware pipe, which also receives the drainage of the Pembroke-road and Hutchinson’s estate. In consequence of the difference in size of sewers, as here marked out, the basements of a vast number of houses in the New-town and other places have been flooded from time to time, and serious inconveniences have in consequence arisen to the ratepayers in those localities. It is worthy of remark, that after representations made by the vestry to the General Board in August last, they directed a sewer of equal size, viz.: 5ft. 6in. by 3ft. 6in. to be substituted for the 18 in. stoneware pipe, which will effectually remedy the very serious evil pointed out. * * * * * The total lengths of sewers in this parish, under the immediate direction of the vestry, are as follows: Brick Sewers 27¾ miles. Pipe Sewers 7⅙ ,, Open Sewers 1¾ ,, The open sewers are not in closely populated districts, but chiefly in that portion of the parish at present under cultivation as grass land or market gardens. The VESTRY have lowered the crown of sewer in New-street, to a length of 320-ft., have reconstructed a length of 42-ft. 2-in., by 2-ft. 6-in. sewer in Charles’-mews; have laid down a length of 115 ft. of pipe sewer in King-street; and 140-ft. of 12-in. pipe in Sloane-place, in lieu of the old dilapidated brick drain. These Sewers have enabled owners to drain their several premises. * * * * * There have been 45 new Gulleys constructed for carrying off the surface water from the roads, and many altered, repaired, and cleaned. Air shafts have been formed for carrying off the poisonous Gases from the Sewers; and many Gulleys have been trapped. * * * * * The flushers have cleansed about 8 miles 3482-ft. of brick sewer, removing deposits therein, varying from 6 inches to 2-ft. which deposits have been carted away, and have also flushed with water from time to time pipe sewers to an extent of 7½ miles.
