pH. The reciprocal of the logarithm of the hydrogen-ion concentration. The concentration is the weight of hydrogen-ions, in grams, per liter of solution. Neutral water, for example, has a pH value of seven and a hydrogen-ion concentration of 10-7.
PROPERLY SHREDDED GARBAGE. The wastes from the preparation, cooking and dispensing of food that have been shredded to such a degree that all particles will be carried freely under the flow conditions normally prevailing in public sewers, with no particle greater than one-half inch (1.27 centimeters) in any dimension.

WASTEWATER FACILITIES. The structures, equipment and processes required to collect, carry away and treat domestic and industrial wastes and dispose of the effluent.
