SEWER ADVISORY COMMITTEE PRELIMINARY REPORT TO THE BOARD OF SELECTMEN
January 16, 1978
During the past six months the temporary Sewer Advisory Committee
has reviewed matters relating to the extension and maintenance of
Lexington's sanitary sewer system, as requested by the Board of Select-
men in May, 1977 We submit these findings and suggest that our report
be considered the first in a continuing citizen advisory process of
sewer service delivery
120
Selectmen's Meeting January 16, 1978
The scope of our review has followed the five part list of
topics suggested in the Selectmen's charge, which requested specific
advice on 1) reasonable objectives for substantial completion of the
system, 2) viable alternatives to the community collector system,
3) procedures for establishing desire/need for sewering, 4) possible
betterment formula adjustments, 5) financial information on costs of
conventional sewerage compared with on-lot subsurface wastewater dis-
posal In addition, we comment on the proposal for capitalization
through bonding of the remainder of the system which is presently
under consideration, but was not contemplated at the time this com-
mittee was formed
Lexington joined the North Metropolitan Sewerage District of
the Metropolitan District Commission in 1899 when a 15" interceptor
sewer with a design capacity of 2 8 million gallons per day (mgd) was
extended to the Arlington/Lexington boundary to receive our municipal
sewage By 1953 a 20" interceptor designed to carry 5 7 mgd was
necessary, and this was supplemented by another 36" line with 27 3
mgd design capacity in 1968 These increases to our outflow capability
were a result of the town's policy of providing municipal sewerage
facilities to as many residents as possible with the result that now
86 4% (7,304) of our dwellings are serviced as of March, 1977 The
remaining 13 6% (1,151) are not sewered, of which 6% (488 houses) do
not have sewer available We understand that sufficient capability
is available in the MDC system, which has a design capacity of 35 8
mgd, to handle Lexington's maximum flow calculated at approximately
12 5 mgd (Bedford included) A fourth collector sewer which would
cross through Lexington for the exclusive use of Bedford is now under
consideration by the MDC
Expansion of our local system has been continuous since 1899,
but has come into question primarily because of the increasing costs
associated with sewerage The town's responsibility to provide a
community sanitary sewer to all occupants is uncertain as the un-
precedented high costs place an overwhelming tax burden on the prop-
erty owners Investigation of past projects shows that the commit-
ment to sewer has always involved a financial liability by the town
which was not recoverable, and constituted a deliberate subsidy in
the public interest Betterments, i e , reimbursements to the town
by private parties, have been based upon several variables These
include the average per foot costs of lateral sewers over the previous
five years, lot area according to the total limit of work for the pro-
ject, and a setback calculation This assessment formula assumes
that 50% of the cost is borne by abutters, divided between the two
sides of the street, with the remaining 50% paid by the town (1/4-
1/4-1/2), This subsidy plus the betterment constitute the major
financial support for local sewerage projects Occasionally state
and federal funds are available for portions of the municipal system
(notably the Woodhaven trunk and the Hanscom Field force main)
121
Selectmen's Meeting January 16, 1978
After detailed analysis of sewer assessments (Table 1) we find
that betterment cost recovery percentages have dropped during the
last five years Although these calculations are not as accurate
as we would like because they are based on aggregated numbers which
include non-betterment projects, they are useful as a comparison
and show that the percent of actual sewer cost recovered is con-
tinually lessened This is due to the tripling of construction
costs, the costs of trunk sewers and other capital costs, and the
cost of building sewers past town-owned land The percentage re-
covered might increase if an adjustment factor for eventual service
connection payments is included; these are backcharged to abutters
at the time household connections are made However, it must be
emphasized that we are unable to establish that our current better-
ment assessment practices have ever realized the assumed 50% cost
recovery
As the cost of sewering has roughly tripled per lot in the past
five years (Table 2), and approximately 448 homes are presently with-
out access to sewer service, it is necessary to decide if an expendi-
ture which (based on a per lot average of $6,000) could amount to at
least $2,688,000 should be made in order to accommodate our entire
existing population (with the exception of 67 houses which it has
been determined are impractical to reach)
In order to arrive at a recommendation the committee requested
a comparison of the existing 1/4-1/4-1/2 five year average method
In a random sampling of final assessments from actual sewer projects
the new formula showed a greater than 50% reimbursement giving the
town a more equitable rate of return In each case the old method
returned less than 50% These results (Table 3) point out that the
three year average of previous costs and a 1/3-1/3-1/3 plan of assess-
ment keeps the estimated cost closer to the actual cost of sewer con-
struction The new method also shows greater tolerance for the time
lag between assessment and completion of construction
Of all communities investigated (Bedford, Belmont, Boston, Needham,
Wakefield, Wellesley) it was clear that sewer cost recovery percentages
vary according to local policy For instance, Wellesley charges a
flat rate per lot which does not attempt to cover costs Boston, on
the other hand, collects about 3/4 of the costs of its sewers The
consensus of this committee is to suggest that if the Selectmen de-
cide to implement the substantial completion of our sewerage as de-
fined by the DPW/Engineering priority list dated November 21, 1977,
they consider changing the betterment formula in order to allow the
town to regain a larger portion of the total financial outlay The
Selectmen could achieve this goal by averaging costs over three years
and reducing the town's share to 1/3 as illustrated It would also
be possible to change only the three year timespan while continuing
to use the 1/4-1/4-1/2 formula In the latter case this action would
not necessitate a change in the language of Chapter 221 of the Acts
II/
of 1926 which would be needed otherwise A majority of this committee
122
Selectmen's Meeting January 16, 1978
favors the final alternative
Other methods of sewer cost recovery which were discussed and re-
jected include imposition of a cost ceiling above which the town would
refuse to sewer an area, imposition of a flat rate charge to abutters
for sewering lots above a certain pre-determined rate, and assessing
specific projects without averaging (which would have the effect of
forcing some homeowners to pay premium prices for their very expen-
sive sewers)
Procedures to be followed in establishing need and desire for
sewering should include a preliminary sign-up with the Selectmen who
would forward requests to DPW/Engineering for cost estimates Board
of Health participation as defined in Title V of the State Environ-
mental Code would continue; it should emphasize proper maintenance
and rehabilitation of on-site systems It could provide citizens
with financial information based upon typical Lexington projects of
septic system as well as conventional sewerage A booklet could be
prepared describing the petition process and the assessment formula
as well as information on the care of septic tanks and other allow-
able methods of handling failing systems such as humus toilets (clivus
multrum)
In order to arrive at an estimate of the relative dollar costs
of conventional sewerage versus septic tanks, the costs of staffing
and operating a septic system management program with full municipal
control and equipment ownership were reviewed This was based on a
community with 3,000 existing septic systems (roughly twice the amount
now functioning here) as reported by the Metropolitan Area Planning
Council Water Quality Project (Table 4) Their total of $70,000/yr
should be reduced for a smaller service load Billings to owners
would vary from $20 each if 1000 systems were serviced to $50 per
cleaning when annual service totals 400 jobs With federal assis-
tance in purchasing a pumper truck, the costs decrease about 20%,
ranging from $16 to $41 per job Since town-owned pumpers are totally
user supported they may exceed average private fees if less than 600
tanks are pumped annually Therefore, Lexington might best utilize
contract services combined with municipal inspection to provide the
most economical combination of private and public management The
possibility of developing a septic system management program of some
sort should be given consideration in order to accommodate the exist-
ing homes which will never be serviced by municipal sewerage under
any plan The committee is unable to recommend this exclusively as
an alternative to the substantial completion of our system as there
are current regulatory obstacles to communal septic tanks in Massa-
chusetts
Although the proposal to expand and complete the sewer system
by means of a bonding authorization has not been presented in detail,
we feel that this may be a justifiable action to take We would
suggest that more, not less, review of sewer projects should be pro-
123
Selectmen's Meeting January 16, 1978
vided and that a permanent sewer advisory committee should be appointed
by the Selectmen to assist in sewerage planning The selection of
sewer project priorities affects the development of the town and in-
volves judgements of where the need is greatest These effects of
sewering should be reviewed and discussed During our brief span of
operation the committee has received nine unsolicited letters in addi-
tion to a number of telephone calls and conversations with citizens
regarding sewer problems We believe that this indicates a real need
to increase contact with townspeople as the complicated design and
political aspects of sewering are addressed
Another recommendation of the committee is that applications for
permits for building additions or alterations should be checked by
the Board of Health to determine if the existing septic system is
adequate Similar information should be supplied by the Board of
Appeals for variances and special permits
We also feel that there should be a clear plan for the proposed
sewers with precise statements, topographical maps, and estimated
costs Laterals should be identified separately from trunks and
interceptors Cost figures should allow for inflation In the
plan the highest priority projects should be identified
It was beyond the range of this investigation to consider the
economic effects of the revised MDC billing system which will be
U
based on volume rather than number of connections Sewer use
charges should be considered in cost analyses of system expansion,
and would provide a fertile area of inquiry for additional advisory
reports
We wish to thank staff members of the DPW/Engineering, Board of
Health, Town Manager, and Board of Selectmen offices for invaluable
assistance as well as many citizens for helpful contributions In
particular, Julian Bussgang has spent considerable time studying and
clarifying cost figures on the Lexington sewers
This opportunity to examine and discuss the variety of issues
and practices relating to sanitary sewage installations and related
matters has been extremely interesting We thank the Board of Se-
lectmen for giving us the chance to prepare this report, and look
forward to augmenting these comments should it be deemed necessary

Mrs Crothers informed the Board that the committee had tried to
confine the report to the original five topics that the Board had
suggested; they had to broaden some to try to pick up the recent
$2 million bonding, for which we had a minimum of information We
focused on the betterment formular (the Committee points out that
costs recovery via the betterment formula has not accomplished what
some of us thought) and how the proposed bonding would pertain to
that formula We had some question about the advisory capacity of
the Town Meeting, and we felt that their review should be based on
a very specific priority and map plan, so that the Town Meeting would
have a careful understanding of the proposal The committee feels
that the map has insufficient information on how it would be bonded
125
Selectmen's Meeting January 16, 1978
Mr Bailey said that it was recommended at Town Meeting last year
that we create a permanent advisory committee We opted to create a
temporary advisory committee and we gave a very specific charge, which
got to the core of the difficulty we were having with Town Meeting,
and the report we got back doesn't help us any further in solving the
credibility problem of Town Meeting than it did a year ago
Dr Nill, Sewer Advisory Committee, said that on the first charge,
the committee all agrees that we would like to finish sewering to some
reasonable point On the second charge, there really aren't many al-
ternatives
Mr Bailey said that what you would like to have done is to have
the whole Category A Streets complete engineered and each batch pre-
sented to Town Meeting It will take us a long time to engineer all
of them, and what we tried to do was bite off bits and pieces, depend-
ing on what the pressures are of that year, and engineer them and con-
struct them. Otherwise, if we are going to do it all at once, we are
going to have to get it all put together now, sell the whole $2 million
- fully engineered right now - and then deal out the money and the
programs over five years
Dr Nill said that we want to know conceptually what areas, how
would you start the first year, what would you do the second? He
did not think it is required at all that the engineering be done
It was suggested that this statement be put in writing
Dr Nill said that the problem the Board is going to face is that
at some point you do all of Category A and you declare the Town's sewer
system complete (by definition), what do you do to the person who has
a septic system that fails and you say that you are sorry but the Town
is finished and we won't entertain your petition
The Board agreed that anyone can petition
Mr Hutchinson said that it is entirely feasible that somebody
in Section C could come before the Board two years from now and say
that he needed help, and perhaps some groups in Section A might be
fine and not have a problem We would then consider the problem area
Mrs Crothers asked if the bonding is a complete spending situa-
tion or is it possible for some unknown reason that it could be termi-
nated?
Mr Hutchinson replied that it is an authorization for the Board
of Selectmen to address the sewer planning of the Town and to go for-
ward and execute it
After further discussion, the Sewer Advisory Committee agreed to
submit conclusions and recommendations to the Board
Mr Martin, Assistant Town Engineer, explained types of sewer
projects which might be combined over the next three to five years
Upon motion duly made and seconded, it was voted 5-0 by roll call Executive
vote to go into Executive Session, with no intention of resuming the Session
open session, for the purpose of discussing strategy with respect to
