How to Determine Sewage Amount of Domestic Wastewater

Since domestic sewege consists almost entirely, as to volume, of the water that enters the houses from the water mains, a close approximation to the volume to be expected froma given population can be made by using for this purpose the figures for the water water consumption of the town in question.

All of this does not reach the sewers, much of that used for stream purposes (all used by the stream railroads) and that used for street and lawn sprinkling and leakage from mains and services and other small amounts failing to reach them. On the other hand, to that which reaches the sewers must be added seeoage of grouns-water, which should be negligible, but in some systems forms more than half of the sewage reaching the outlet.

With the domestic must be included that which is sometimes classified as "commercial" being that from stores, hotels, etc..,since this is similar in character and is discharged into seperate sewers; although it is desirable to consider it separetely when designing the collecting sewers for the commercial disrtict. The same applies to industrial sewage, pr liquid trade wastes.

Water and Wastewater Engineering The Best Reference Books

These are the most known books on water and wastewater treatment;

1- Wastewater Enginnering - Treatment and Reuse, Writers: George Tchobanoglous, Franklin L. Burton, Franklin Burton, H. David Stensel, Publiser: Metcalf & Eddy

Saying this book, "Bible of the Environmental Engineering" is not an exaggeration. Thousands of Environmetal Engineers and Scientists keep this book in their library.

2- Wastewater Engineering: Collection, Treatment, Disposal

This is also a Metcalf publishing on wastewater collection.
