HARRIS! IN Si reet. 46 EAST ORANGE AND ITS POINTS OF INTEREST. Mention has been made of the unusually large percentage of the sewers through the townshipwhich are under water pressure. The intricate topography of the town made several heavy cuts—in somei ases over thirty feet, necessary. In all these deep cuttings the water level is now far above the sewers; a headpressure of over twenty feet 0( curring in several places. In addition all the mains located in the valley.

Under these circumstances, despitethe greatest care and much expense, a considerable volume of ground water finds its way into thesewer pipes. When it is remembered that there are over 2,600 joints per mile, some of them o\er sixfeet in circumference, the practical impossibility of making actually impervious sewers under the con-ditions named with vitrified pipe and cement becomes apparent. But this flow from the twenty-five milesof pipe sewers was limited to a very small volume, probably about gallons per second. It was necessary, however, to build the outfall sewer with-a size beyond the maximum vitrified pipe,and a brick sewer was therefore constructed for 2,000 feet through a difficult formation, a timber cradlebeing used under the sewer.
