I have gone into the subject in this report in a quite general and untechnical way, and I shall be pleased to answer any further questions which you wish to ask me.
Mr. Tawney. Where are the plants, which you speak of, situated?
Mr. Paterson. At Wimbledon, which is part of London.
Mr. Tawney. Are they operated by the municipality or by private interests?
Mr. Paterson. They are operated by private interests.
Mr. Tawney. Do these private interests buy the sewage?
Mr. Paterson. The sewage is delivered to the works free of charge. Speaking from memory, the cost at Wimbledon is about 75 cents a ton. They are getting rid of it for nothing, and, in addition to that, they give the land necessary for the treatment.
Mr. Tawney. How long has that plant been in operation?
Mr. Paterson. About a year. On account of the war it has been shut down two or three times by the Government taking the men away; but now it is practically under Government control, for it comes under the Munitions Department. It is now looked upon by the Government as a necessary national project, and comes under the munitions department.
Mr. Powell. Because of the gasoline they get?
