“The ejectors are cast-iron receivers of a suitable form, placed underground at depths to suit the locality, into which ejectors the sewage flows through the ordinary pipe drains from the houses. As the liquid rises in the interior of the ejector, and when full, it lifts a valve and admits compressed air from an engine which supplies the entire district. The ejectors are thus emptied of their contents, which are blown out in about eighty seconds of time, and the sewage passes through cast-iron main pipes of suitable diameters to the land, or other outlet provided to receive it, or it may be distributed upon the waste land as it passes through.”
(7.) The dry systems, which consist of—
(a.) Earth closets;
(b.) Tubs, as the Goux, &c.;
(c.) Pails, as the Rochdale;
(d.) Middens.
But all these dry systems require some system of sewers to carry off rain-water, slop-water, &c., and in my opinion are not suitable for very large communities.
[174] If the sewers vested in and belonging to a local authority are allowed by their negligence to get out of repair, they are liable to an action for damages (Vide ‘Fitzgerald’s Public Health Act,’ 3rd edition, p. 19). Keeping in repair does not, however, include construction of entirely new works. (Ibid.)
[175] The sewers provided by a local authority must be sufficient to carry off the ordinary sewage and rainfall of the district, but they need not be sufficient to carry off an extraordinary flow of water caused by a storm; damage caused by that comes under the definition of damage caused by the act of God, for which there is no individual responsibility (Ibid. p. 20). This clause seems to insist upon sewers carrying the rainfall.
