Excerpt from The Cornell Civil Engineer and Transactions of the Association of Civil Engineers of Cornell University, Vol. 28: October, 1919 Sludge bed: One square foot of area per five persons, or 100 square feet. Plans called for 342 feet of 8 terra cotta sewer, Imhoff tank 10 feet long by 7 feet wide bv 14 feet deep, with 8 concrete walls reinforced against earth pressure, the upper and lower stories divided by galvanized sheet iron. No. 14 B. 8: S. Gauge, reinforced by 3 angles, and the whole coated with Bitumastic Enamel. In the dosing chamber were placed two 5 alternating Miller siphons to dose the two sand beds. The sand beds were 36 feet square each with a minimum of 30 of sand and 6 of gravel. The sludge bed was made 10 feet square with 9 of sand and 6 of gravel. The excavation for the sludge tank was made without the use of sheeting and the earth was used as a back form. The galvanized sheet iron was built up by the foundry to proper dimensions, and after the concrete had hardened, the whole affair was lowered into the tank and the projecting ends of angle reinforcing cemented into the walls. The edges of the sheet iron fitted neatly up against the concrete walls and were made leak-proof by strips of wood on both Sides of the iron. The sheet iron and angles were given a liberal coat of Bitumastic Enamel paint about thick. The makers claim for this material long life, resistance to heat and cold and thorough protection to the iron. The requirement for sand in the beds was that it have an effective Size of from 30 to 45 millimeters, with a uniformity coefficient of The gravel for the beds was specified to pass a 1 screen and to be retained on a screen.
