In 1892 was introduced the sewage system, which now includes 6 m.
The drainage of the station is all modern, and the sewage is disposed of on a sewage farm under the direction of the war department.
River water, especially that which has received town sewage, or the drainage of highly manured land, would naturally be considered most suitable for irrigation, but excellent results are obtained also with waters which are uncontaminated with manurial matters, and which contain but 8 or io grains per gallon of the usual dissolved constituents of spring water.
They may also take proceedings in respect of the pollution of a stream by any solid or liquid sewage matter.
In several places the debris within the walls is saturated with sewage, and the water of the Fountain of the Virgin, and of many of the old cisterns, is unfit for drinking.
