including the determination of the quantity from each plant
 "(4 To determine the adequacy of the present sewer system and it's component parts to meet existing and probable future requirements and the necessity, if any, of inn provements or endorsements. This will involve a study of the density of population in present built-up areas and estimates of the probable density or new areas and sewage flows therefrom, tributary to the system. Particular attention will bc given to the separation of storm and sanitary flows and the discharge of industrial wastes.
 May Add to Present System
 "(5) To prepare a comprehensive plan of the sewer system. This will involve a determination of the rein forcements to the existing system. if any, to adequately carry the esti- mated sewage flow; new laterals within the existing system, and to outlying districts tributary thcreto; new trunk and main collecting sew CTS and possible pumping stations required 10 adequately and eco nomically convey all sewage 10 a common point or disposal.
 "(6) To make analysis Of the bactcrlological and chemical char acteristics, as reported by the Indus trial Waste Board, from which determination may be made of the method of treatment best adapted 10 provide the degree of purification necessary to satisfy all requirements. This will involve a study Of the pres ont sewage disposal plant alN de- termination as to what extent it may be practically utilized to pro- vide this treatment.
 "G) To make study of the char acter of industrial wastes and their relation to the problem of sewage treatment. This will involve a study of the first and second biennial re- ports of the Connecticut Industrial " condition of the Mattabesett river insofar as it relates to this problem.
 "(S) To study and compare rari- ous methods of sewage treatment end recommend the one most suit able to provide the degree of puri- fcation required.
 "(D To prepare general layout maps and plans for sewage treat ment works which will adequately and economically provide the method of treatment proposed. These will show the sizes location and general management of the various units for primary and final treat nent with adequate provision for future extension. Maps and plans, however, will net be detailed con struction plans, but general plans sufficient 10 show the mcthots proposed and give the basic information required for the dc velopment of detail construction plans when needed.
