MILLIGRAMS PER LITER or mg/l. A unit of the concentration of water or wastewater constituent. It is 0.001 g of the constituent in 1,000 ml of water. It has replaced the unit formerly used commonly, parts per million, to which it is approximately equivalent, in reporting the results of water and wastewater analysis.
NATURAL OUTLET. Any outlet into a watercourse, pond, ditch, lake, or other body of surface or groundwater.

ppm. Parts per million by weight.
PRETREATMENT. The treatment of wastewaters from sources before introduction into the wastewater treatment works.
PROPERLY SHREDDED GARBAGE.

PUBLIC SEWER. A sewer provided by or subject to the jurisdiction of the village. It shall also include sewers within or outside the village boundaries that serve one or more persons and ultimately discharge into the Village Sanitary or Combined Sewer System, even though those sewers may not have been constructed with village funds.
