Small Community Water And Wastewater Treatment

Presents summaries of drinking water and wastewater technologies suited to small communities. Presents technical and cost information on those technologies most widely used. The wastewater treatment technology overviews covers: collection systems, treatment technologies, and sludge treatment and disposal methods. Case studies of six small communities address their unique drinking water and wastewater problems. Resource Directory section lists state and regional organizations that can provide technical and financial resources to small communities. Diagrams and tables.

"This manual contains overview information on treatment technologies, installation practices, and past performance."--Introduction.

These materials, prepared for the U. S. Environmental Protection Agency Technology Transfer Program, were used in presenting Technology Transfer design seminars throughout the United States. When faced with decisions on wastewater treatment system upgrading or replacement, many small communities and rural areas run into financial difficulties. This trio of documents presents the results of research into this problem, which examines various strategies and systems, and their associated costs, in order to arm utilities managers in such communities with information vital to making informed, responsible decisions regarding wastewater treatment.

This report provides general information on the design and selection of wastewater systems with capacities for populations up to 2500. This information is intended for use by individuals with limited experience in wastewater treatment and disposal as a source of available alternatives in small systems, as well as an outline of the steps and procedures to undertake when selecting a particular wastewater management scheme for a small community. Material covered includes: measurement and estimation of wastewater flows; physical, chemical and biological characteristics of domestic wastewater; on-site wastewater treatment and disposal processes; central wastewater collection and treatment systems; operating problems associated with small treatment systems; disposal of liquid effluents and waste sludges; and procedures employed in the selection and approval of wastewater systems. A case history is provided to illustrate the selection procedures discussed within the text.
