                              PREFACE

  This annual report of "Sewage and Water Works Construction 1968" is
published as one part of the basic data program required and authorized in
Public Law 660  (as amended by the Federal Water Pollution  Control Act
Amendments of 1961—(PL 87-88), and by the Water Quality Act of 1965
— (PL 89-234).
  The data published herein provide a continuing and ready source of infor-
mation and reference as to how successfully the national needs in municipal
water supply and pollution control are being met through construction of
the necessary physical facilities.
  This publication also establishes important year-to-year cost trends in
the national economic picture in the three types of public works construc-
tion involved. Such data are valuable not only to Federal, State and local
government authorities and officials responsible for providing water  sup-
plies and for controlling pollution, but are also valuable to the building and
contracting trades and to the engineering profession.
  Effective January 1, 1969, this Administration will no longer include in
this publication series data on waterworks.
  This report was prepared by Kenneth H. Jenkins, Consultant Statistician,
and Florence G. Simmons, Statistical Assistant, under the direction of Jesse
L. Lewis, Chief, Data and Information Services Section; Pollution Surveil-
lance Branch; Federal Water Pollution Control Administration.

                                   CONTRACT AWARDS
A. CONTRACT AWARDS-1968
  Contracts awarded in the sewage and water-
works field in calendar year 1968 amounted to
almost $2.4 billion, broken down as shown below
in millions.
    Sewage treatment
    Collecting sewers
    Waterworks	
     Total 	
                                    866.8
                                    582.5
                                    913.1
             	 			     2,362.4
  Sewage treatment contracts were 45 percent
over 1967 and at the highest level of record be-
ginning in 1952. Contracts for collecting sewers
were 30 percent above last year and also a rec-
ord high. Waterworks contracts  were 13 per-
cent below 1967 but still the second highest on
record.
  The total value of all three categories is about
26 percent above 1967 and is the highest figure
on record. On a  constant dollar basis (1957-59),
the increase from 1967 was about 10 percent.
  Each of the  above totals is  based  upon an
identified and an apportioned figure. The iden-
tified contracts are those  for  which  the  de-
scriptive information available  clearly states  a
single  type of construction. Those contracts
that cover more than a  single  type are called
"combination"  contracts. These  combination
contracts are then  apportioned to the  sewage
treatment works,  collecting sewers, and water-
works categories on the basis of known national
experience in each of these.

B.  METHOD OF  DATA COLLECTION
  The  contract award data presented  in this
publication for the year 1968 result from the
careful  examination of over 100,000 contract
notifications  in  the sewage and  waterworks
construction  and  related fields.  All notifica-
tions of similar contracts awarded in the same
geographical  area are checked to  reduce  the
chance of duplication. Certain contracts, pri-
marily those covering sewage treatment plants,
are checked and verified by the various State
water pollution control agencies.
  The data on which this report is  based were
obtained from:

  1.  F. W.  Dodge Corporation daily reports
       on construction in the sewage and wa-
       terworks  fields  in   the  38 Eastern
       States, Arizona and Southern California.

  2.  Various  construction  news  periodicals
       such  as  Construction News Bulletin,
       Pacific Architect and Builder,  Rocky
       Mountain   Construction,    Southwest
       Builder and Contractor,  Denver Daily
       Journal and Construction News Daily.

Practically all of the information  for  the 38
Eastern States is obtained from daily reports of
the F. W. Dodge Corp.
  The data presented are composed of contracts
awarded by municipalities, special districts, and
other  local governmental bodies. A few con-
tracts are included for industries where the cost
of such facilities can be readily identified, and
where  it is possible  to  ascertain that facili-
ties are primarily for the disposal of sanitary
wastes or for domestic waterworks  facilities.

NOTES:
  1. Constant dollars on a 1957-59 base were computed as follows:
Sewers from PHS Sewer Construction  Cost Index (PHS Publication
1132); sewage treatment a composite 45 percent sewers (Publication
1132)  and  55  percent  PHS  Sewage Treatment  Plant Construction
Cost Index  (PHS Publication 1069); water from Engineering News-
Record construction cost index changed to a  1957-59 base.
  2. The Public Health Service sewage treatment data prior to 1957
are composed of identified contracts only. Beginning with  1957, the
figures include an  amount apportioned to sewage  treatment works
from  the "combination" contracts.
  3. Data  on collecting sewers prior  to  1957 are obtained  by sub-
tracting Public Health  Service sewage  treatment  data  from  the
U.S. Department of Commerce sewer data which includes  sanitary
and storm sewerage system as well as  sewage treatment works.
Beginning with 1957, the data  for collecting sewers were assembled
by the Public  Health Service and  do  not include storm sewers.
  4. The  waterworks  data  prior  to  1957  are  based on  records
maintained by the  U.S.  Department of Commerce.  Beginning with
1957, data  were obtained by the Public Health Service.

                  SECTION II-CONTRACT AWARDS-BASIC DATA-1968
  This section presents the basic data as com-
piled; combination projects have  not been
apportioned.   Tables  of  contract  awards  by
population size  groups, contract  size groups,
drainage basins  and States are included.
  The population size group tables do not refer
to the population served. They represent  the
size  of the community  in which each contract
was  awarded. The population size groups of
some contracts were unknown; these contracts
consist primarily of new  towns or administra-
tive  districts.  The  cumulative   percentages
shown in these tables are based on the known
population groups.

A. SEWAGE TREATMENT WORKS  CONSTRUCTION
  The sewage treatment  works are  presented
in two categories, namely, NEW  PLANT and
OTHER. The "NEW PLANT" classification in-
cludes  stabilization ponds and  appurtenances.
The "OTHER" category includes replacements
and additions to existing treatment plants, in-
terceptors, and outfalls. This  category  also
includes contracts  whose costs cannot be sepa-
rated   between  "New  Plant"  and  "Other."
Therefore, the "Other"  classification  may in-
clude a few new plants.
  In 1968 the level of contracts awarded for
construction  of sewage treatment works in the
United States reached a level of $866.8 million.
Of this amount $773.9 million covered contracts
identified  as  to specific location and type of
construction.  The following Tables 5 through 8
inclusive relate  only  to  contracts individually
identified for  sewage treatment facilities.
  Lists of the locations of contract awards for
sewage treatment works are available upon re-
quest. Write  to Director, Division of Pollution
Surveillance,  Federal Water Pollution Control
Administration, U.S.  Department of the  Interi-
or, Washington, D.C. 20242.

B. COLLECTING SEWER CONSTRUCTION
Collecting1 sewer construction for 1968 totaled
$582.5 million. Tables 9, 10, and 11 analyze the
contract award data which was specified as
purely collecting sewers (i.e. $517.6 million),
and do not reflect any portion of the combina-
tion projects. The tabulation of the collecting
sewer contract awards by States appears in
Table 3 of Section I.
The collecting sewer classification does not
include storm sewers.
C. WATERWORKS CONSTRUCTION
The waterworks data are broken down into
four categories, namely, SOURCE, TREAT-
MENT, DISTRIBUTION, and MISCELLANE-
OUS. The "SOURCE" group includes contracts
awarded for wells, surface source development,
and transmission lines. The "TREATMENT"
area includes contracts for plants and auxiliary
facilities. The "DISTRIBUTION" category in-
cludes contracts for ground storage, elevated
tanks, and distribution systems. The "MISCEL-
LANEOUS" classification includes contracts
for pumping facilities and for water systems in
general. When it is not possible to code a con-
tract that is known to pertain to water into
source, treatment, or distribution then it is in-
cluded in the totals for miscellaneous.
Contract awards for waterworks construc-
tion in 1968, including an apportioned amount
from the combination contracts, totaled $913.1
million. The tables following refer only to con-
tracts that pertain exclusively to waterworks
(i.e., $866.5 million).
