ADDITIONAL RESERVOIR PLANNED FOR CINCINNATI.

ADDITIONAL RESERVOIR PLANNED FOR CINCINNATI.

Superintendent J. A. Hiller, of the Cincinnati, Ohio, water works is planning for the future needs of his city. He recently stated that there have been times when on certain days 5,000,000 gallons of water in excess of the entire capacity of the water works have been used. It was the reservoir in Eden park that helped out and, so, instead of abandoning such reservoirs as there are, as suggested a year ago, it is clearly necessary to build more. Superintendent Hiller said: “I am planning one of 200,000,000 gallons for the hills wests of Mill creek. I have the site in mind. The water for the western portion of the city is pumped by the station on Queen City avenue. It has to run through the entire central part of the city. With a reservoir on the western hills in case of need we could have stop valves this side, prevent the flow to the central portion and pump the water to the western portions. In twentyfive years new water works will have to be built. The gravity tunnel can carry but 100,000,000 gallons a day and the filter plant has a capacity of only 112,000,000 gallons a day. The intake tunnel will permit of but 120,000,000 a day. Recently we used 105,000,000 gallons or five millions more than capacity of the gravity tunnel, the avenue by which the water flows from the California reservoirs to the Eastern pumping station at Torrence road and Eastern avenue. This was a ‘peak’ load, but it shows what we are approaching. The new loop will come in handily in case of a break in the 60-inch main. It is a 36-inch main and could supply about 15,000,000 gallons a day. But the consumption of the central portion of the city now is 24,000,000. Hence 19,000,000 would have to be found elsewhere. Some of this could be ‘bled’ off from the high service, but the Eden Park reservoir would have to supply the bulk. It has a capacity of about 100,000,000, so it would carry us about five days. When we had a break, not long since there were five haurs during which the western station on Queen City avenue did not pump a drop of water. Had there been a reservoir on the Western Hills it could have gone on for over a week. When we build a new gravity tunnel it will mean an expenditure alone of over a million dollars. The present is four and a half miles long and is seven feet in diameter. There is a stretch of about two miles through Norwood for a new loop main. With that exception it is all completed and the pipe and everything for that section is ready. There is no occasion for alarm about a water supply, but it is the part of wisdom to face actualities and to be prepared for meeting them in due season.
