Author Description

Excerpt from The Sewerage of Two New Hampshire Towns (Keene and Laconia) The Ashuelot is subject to high oods. The outlet of the central main sewer is sometimes submerged to a depth of six or eight feet, and much of the at area through which the Beaver brook main runs is under water, in some cases over the t0ps of the manholes. These conditions indicated that it would probably be necessary to make use of jet pumps near the outlets of these lines, to maintain a ow during high stages of the river. It was found, however, that during the spring ood of 1884, which was unusually high, the natural ow of the sewers maintained a constant current through the whole system. No inconvenience was caused by the failure of the house drains, even in the lower portions of the town, to dis charge freely and it was thought unnecessary to carry out this part of the plan at present. The indications now (1891) are, that such an aid may be required at the outlet of the central main. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
