    Provisional Walker's Improvements in Utilizing Sewage, <§c. more liquid portion thereof may flow over by a suitable passage back into the sewer or drain again, or into another or other secondary subsiding well or reservoir, or wells or reservoirs. These latter subsiding wells or reservoirs may have a communication from their lower parts to the lower part of the first or pump well or reservoir, to be opened when required to allow the finer 5 subsidence therein to pass into the pump well or reservoir, or they may be separately pumped. The matter as collected by subsidence in the pump well or reservoir referred to I draw from the lower part thereof by means of a pump through suitable piping, and thence by other pipes I conduct it to other tanks or receivers, which I call field tanks or receivers, at distances apart as 10 may be required. These latter tanks or receivers are formed deep at one end inclining upwards to the opposite, and the fluid matters from the first wells or reservoirs are caused to flow into these field tanks or receivers, and to over¬ flow at the shallowest end into troughs or gutters, laid so as to distribute the fluid matters over the district for irrigation. In the passage of the highly 15 charged liquid matters through these field tanks or receivers subsidence takes place, and when desired the matters subsided may be removed therefrom to be distributed. The bottom of each field tank or receiver may be provided with a passage capable of being opened to a drain when desired to drain it before taking out the solid matter. ' 20 The pumping apparatus I prefer to employ, and which may be worked by a steam engine or other suitable power, is formed with a chamber connected to one end, or one to each end of the working barrel of a pump, having a flexible diaphragm across each chamber to prevent the sewage matters coming in contact with the clean water or oil in the working barrel on one or 25 both sides of the piston. Pumping apparatus similarly arranged is also applicable to other cases where it is desirable to keep the working barrel and piston free from injurious effects of the matters to be raised or forced. Where circumstances may render it desirable, the subsidence may be obtained by the use of three or more reservoirs, each reservoir being of sufficient size in SO relation to the quantity of flow in a given period to leave time for the contents of one reservoir becoming solid, or partially solid, whilst one of the others is being filled by subsiding matter. Sluices or stopways are provided to regulate the direction of the various flows, or to close the passage by any of them as required. 35 i
