    T. $ T. F. Walkers Improvements in Apparatus for the Utilization of Sewage. of the sewage matter, and thereby they serve to trap the outlets of the drains, and prevent the return of foul smells up the drains. / The heavier solid matters contained in the sewage matter will be arrested in the reservoir b9 and sink to the bottom thereof, whilst the light bodies in suspension, such as paper, rags, and other fibrous matters, will pass with the 5- more liquid portion of the sewage matters over the wall 6l, forming one side of the trough bt and such light bodies in suspension will then be intercepted, by the horizontal grating c, which may be continued vertically up the wall c1 if desired, h2 is a screen by which corks and other light floating matters are detained in the trough b9 but which admits of the sewage passing [under it IQ over the wall bl on its way through the grating c to the settling pit or reser¬ voir d; 6* is bridge over the wall b1. The trough b is, by preference, formed with inclined ends b3, 63, to facilitate the removal from the bottom thereof of the matters collected therein by means of scrapers or other suitable cleansers. A form of scraper suitable for 15 the purpose is shewn at e attached to a chain, or it may be a rope or a rod el operated by a winch or by other suitable means, and thence th& matters may be delivered into trucks, boats, or other receivers to be conveyed away. r The more liquid portion of the sewage matters as it passes from the 20 trough b is received in at the end d1 of the pit or reservoir dy and the bottom d2 of this pit or reservoir d is inclined to the central gutter d3 to facilitate the collecting and drawng off therefrom of the more solid portion of the sewage matters formed by settling or subsidence in this pit or reservoir. The gutter d3 is also inclined to one end of it, where it communicates by a 25 suitable channel with a well or receiver. These settling pits or reservoirs may be arranged in pairs, so that one of them may be receiving matters for subsidence, whilst the matters subsided are being withdrawn from the other. i $ * •* .f , The more solid matters collected by subsidence in the reservoirs d may be 80. withdrawn therefrom or from the receiving well from such reservoir by pumping apparatus such as that described in the Specification of the Patent before referred to, or such as that herein explained, or by other suitable means. The more fluid portion of the sewage matters will flow from the surface of the settling pits or subsiding reservoirs d into the gutter /, from 35 which it is raised or forced by suitable pumping apparatus into elevated ; reservoirs or feeders, from which by suitable conduits it may be conveyed for irrigating purposes to the districts desired.
