3. REIMBURSEMENT FOR WATER AND SEWER MAIN EXTENSIONS.
John Bock reviewed the existing policy of water and sewer
main extension, where the City incurs the initial expense of
extending the main subject to recovery from the requesting
party. Utilities staff has proposed that recovery shall be
upon completion of said extension and shall involved the
entire cost of the main extension.
The Municipal Code shall read: "Recovery shall be from the
requesting party or parties and shall be upon completion of
said extension. Recovery shall be defined as the entire
cost of the main extension. The requesting parties shall
demonstrate the ability to reimburse the City for
construction costs prior to construction."
Ms. Bradshaw questioned what percentage of prior main
extensions has been recovered. A memo from John Bock dated
February 2, 1998 is attached answering Ms. Bradshaw's
question.
Ms. Habenicht moved;
Mr. Guy seconded:
Ayes:

4. GISEN V. CITY OF ENGLEWOOD -3605 S. BANNOCK.
John Bock reviewed events leading to the Summons served by
Lera Gesin, owner of 3605 S. Bannock St. The Gisens are
petitioning to encroach into the City of Englewood's City
Ditch right-of-way on the south boundary of their property.
The attorneys are preparing discovery for the trial. John
will apprise the Board of new developments.
5. POST OFFICE DELILVERY AND LATE FEES.
John Bock noted that the Utilities Department has received
numerous complaints from customers that the Post Off ice
delivered water bills late. The Board recommended that if a
bill is delivered late, the Utilities Department could waive
the late charge one time if the customer produces the
envelope with the postage mark. Late charges could be
waived, at the Director's discretion, if the records show a
good payment history. A notice will be posted on future
bills.
6. GREASE INTERCEPTOR ORDINANCE.
The Board received the existing Oil and Grease Interceptor
Ordinance (Municipal Code #12-2-4F). Stu discussed allowing
variances to be granted administratively and eliminating
"with the approval of the Water and Sewer Board" from the
existing code. The Board will discuss the variance at the
next meeting.
7. CDM -PROPOSAL FOR ADDITIONAL ENGINEERING FEES.
Camp Dresser & McKee will appear at the next meeting to
discuss the need to increase their fees.
8. GROUNDBREAKING FOR THE ALLEN PLANT IMPROVEMENT PROJECT.
There will be a groundbreaking ceremony for the Allen Filter
Plant Improvement Project on Wednesday, January 28, 1998 at
9:00 a.m. at the Allen Filter Plant. All Board members are
encouraged to attend.
9. VALLEY SANITATION DISTRICT.
Stu will be meeting with representatives of the Valley
Sanitation District to discuss a proposal to dissolve the
Valley Water District. The Board noted that they were not
receptive to incorporating the sanitary sewer portion of
Valley Sanitation District. The Board discussed the
proposal and informally adapted the following positions: 1 )
there should be no limits on differential fees, 2) future
taps would only be available under current land use and
zoning, 3 ) the existing Board of Directors must guarantee
that all facilities are in public rights-of-way, 4) The
Board of Directors would remain liable for any decisions
made prior to the dissolution and 5) the contract would be
patterned after and essentially the same as the current
contract with Cherry Hills Village.
The Board adjourned at 6:10 p.m.
The next Water and Sewer Board meeting will be February 10,
1998 at 5:00 p.m. in Conference Room A.
Respectfully submitted,
Cathy Burrage

MEMORANDUM
To: Stu Fonda, Director of Utilities
From: John Bock, Utilities Manager of Administration{fJ
Date: February 2 , 1998
Subject: Water and Sewer Construction Cost Recovery Accounts
Following is a listing of the water and sewer main construction projects funded by the City where
we are still or have recovered our costs:
1. W . Baltic Place from S . Tejon St. to S. Vallejo St.
Constructed in 1983 , 35% of our costs remain to be collected .
2 . W . Hillside Place from S. Tejon St. to S . Zuni St.
Constructed in 1982, 50% of our costs remain to be collected.
3 . S. Platte River Drive from W. Dartmouth Ave . south.
Constructed in 1992, 90% of our costs remain to be collected .
4 . S . Decatur St. north ofW. Union Ave.
All costs have been recovered. This is because all the adjacent land was purchased by two
developers, one for an apartment complex and the other for a mini storage business.

1) "Line of Sight" Controls for Union Avenue Pump Station -A hard-wire control
system has been designed for the Union Avenue Pump Station. The controls are for
controlling chemical feed equipment placed in the Old Pump Station. The hard-wire
system entails burying a conduit in the soil between the Old Pump Station and the
Union A venue Pump Station. A change to "line of sight" control system has been
requested by the City due to concerns regarding the poor soils conditions potentially
causing construction, operations and maintenance problems. A "line-of-sight" system
does not have buried conduits and will therefore eliminate the potential problems
related to the soils.
2) Conformed Documents -Conformed documents will be prepared to incorporate all of
the addenda items and the original design information into one set of documents. The
addenda items include Addendum No. 1, 2, 3 and 4. Addendum No. 1 is the
drawings and specifications for the electrical, instrumentation and control designs for
the project. Addendum No.s 2 and 3 primarily contain responses to questions from
the bidders and designs of some miscellaneous items. Addendum No. 4 primarily
contains responses to questions and comments from the City's Building Department.
Addendum No.s 1 and 4 are a direct result of the time constraints imposed on the
project by the deadline for the SRF Loan Application. Had there been more time,
most of the contents of Addendum No.s 1 and 4, and portions ofNo.s 2 and 3, could
have been incorporated into the original design information. The conformed
documents will facilitate the construction of the project by clearly presenting the
requirements to the Contractor.
O:IOYEIAMEN0.4 3
O:IOYE\AMEN0.4
The agreement with Centric/Jones states that the City of Englewood will provide ten
sets of design documents to them for their use. In addition, the City of Englewood
and Camp Dresser & McKee Inc. will need copies for their use.
3) Flood Wall Redesign -The flood wall has had to be redesigned to: (a) improve the
accessibility to the underlying sanitary sewer for the Southgate Sanitation District,
and (b) accommodate the re-alignment of the newly constructed bridge over Big Dry
Creek. In response to requests from the Southgate Sanitation District, the transition
of the flood wall where it crosses over the 60-inch sanitary sewer was redesigned.
The redesign involves opening up the width of the transition to improve the access to
the sanitary sewer.
4)
5)
The flood wall will tie into the newly constructed Windermere Street bridge over Big
Dry Creek. For the original design of the flood wall, the ENGINEER was provided
with CDOT documents for the design of the bridge. Discrepancies in the bridge
design information were discovered during design. To correct the discrepancies, it
was necessary to resurvey the area around the bridge to obtain an as-constructed
topography. Due to site constraints presented in the as-constructed topography, the
flood wall will have to be redesigned where it attaches to the bridge. The redesign
will involve another crossing of the sanitary sewer owned and maintained by the
Southgate Sanitation District. There are a number of alternatives for crossing the
sanitary sewer. The alternatives either impair the accessibility to the sewer or have a
high construction cost and possibly impair the use of some of the facilities at the
Allen Water Treatment Plant. A study of the alternatives is necessary for discussions
and negotiations with the Southgate Sanitation District. Once an alternative is agreed
upon, the redesign can then proceed.
Carbon Supplier Options and Agreements -Operating conditions at the Allen Water
Treatment Plant have rendered a situation where the warranty originally proposed by
the Calgon Corporation for the service contract for the granular activated carbon was
unacceptable to the City of Englewood. The Calgon Corporation was initially
unwilling to rela"X the warranty conditions. In response to this situation,
investigations and negotiations were pursued with a second potential carbon supplier,
ACMS. Calgon Corporation has since changed its warranty to meet the needs of the
Allen Water Treatment Plant. As a result of its negotiations, the City of Englewood
now has two potential carbon service companies to chose from for the project.
Phosphate System -Treated potable water from the City of Englewood's (City) Allen
Water Treatment Plant (WTP) is delivered to customers via a network of water main
piping referred to as the "distribution system." The majority of the distribution
system is comprised of small-diameter (e.g., 4 inch) unlined cast iron pipe, which has
been in service for several decades. Over time, the effective diameter of the pipes in
the distribution system has slowly been reduced by tuberculation buildup on the
internal pipe walls. This has been observed throughout virtually all reaches of the
distribution system . The tuberculation limits the ability of the City to deliver the
required flowrates and/or pressure required by its water customers. Furthermore,
periods of high demand increase the flow velocity in the distribution system , resulting
in shearing of the deposited tuberculation materials. These materials are then
resuspended in the water traveling through the distribution system and are observed
4
6)
7)
8)
O:IOYEIAMEND.4
at customers' taps, which results in numerous "red water" or high-turbidity
complaints from customers.
A two-part program has been proposed by the ENGINEER to mitigate these
distribution system issues. It is recommended that the City continue to mechanically
clean affected sections of the distribution system piping followed immediately by
application of a liquid phosphate solution to prevent corrosion of the resulting bare
metal. The second part of the proposed plan includes continuous feed at the Allen
WTP of a different liquid phosphate solution to further control corrosion and prevent
deposition of particulate matter in the distribution system.
Details of the distribution system issues and the recommended corrosion control plan
are included in the report titled City of Englewood, Colorado: Corrosion Control
Study (CDM 1998). That report also includes a recommended set of tests to be
performed by the City to determine the optimum chemicals and doses to be used. It
is important to note that this program is expected to reduce the occurrence of "red
water" at customers' taps, but such occurrences will not be completely eliminated.
Mechanical cleaning of segments of pipe in the distribution system will continue to
release deposited materials back into the water system for a period of a month or
more following the cleaning. However, the "one-time" application of chemical
following the cleaning is intended to reduce the severity of this effect. Upon
commencement of the preventive program, it is anticipated that over time, the
frequency of mechanical cleaning of the system will be reduced, and subsequent "red
water" occurrences will likewise decrease.
ENGINEER will prepare a preliminary design letter report for the proposed chemical
storage and feed facilities to be installed for continuous feed of phosphate solution at
the Allen WTP. Final design will be authorized, if necessary, after the testing
program.
Emergency Generator -The Allen Water Treatment Plant is provided with electrical
power through two feeders from the Public Service Company. The initial design
considered using one of these two feeders as an emergency power source to the
treatment plant. During the review of the design by the City's Building Department,
it was determined that a stand-alone emergency generator is required, instead of one
of the feeders, to power the ventilation equipment in the high hazard areas.
Sodium Hypochlorite Investigations and Report -The operations staff at the Bi-Cities
Wastewater Treatment Facility reviewed and commented on the final design of the
sodium hypochlorite feed and storage facilities. Their review comments called for
facilities significantly different than what was designed. The as-designed system was
reviewed, documented, and justified.
Assistance with Belt Filter Press Investigations -The existing belt filter press is 10
years old. It has been recently discovered that a slightly-used newer press is available
for purchase through a nearby sanitation district. Preliminary negotiations indicate
that the press can be purchased for $80,000 to $90,000, approximately half the cost of
a new press. Further investigations are necessary to determine the feasibility of using
the press in the new facility. An allowance of $10,000 is authorized to assist the
CITY with the investigations.
5
1.6 Additional Bidding Phase Services
1) Extended Bid Period -In an effort to attract the top local contractors, encourage
competitive bidding, and obtain the best possible bids, the City of Englewood
extended the bid opening date for the project by one month. During the extended bid
period, the ENGINEER interviewed contractors, prepared additional addenda items
responding to questions from the bidders, consulted with the City, attended meetings,
and provided management and administration of the extended bidding period. The
City of Englewood's efforts to extend the bid period has paid off: bids were received
from five top local contractors, the range of bids was very narrow, and the low
bidder's price was considerably below the Engineer's Opinion of Probable
Construction Cost.
2) Final Document Printing -Reproduction and distribution of the design documents to
the bidding contractors, plan rooms , and vendors is essential to attracting interested
parties to the project. The design documents were sold to these parties to cover the
associated costs resulting in a nominal credit to the City of Englewood.
1. 7 Additional Construction Phase Services
1) Extended Services During Construction -In response to requests from several of the
bidding contractors , the City of Englewood extended the contract time for completing
the project. The extended contract time will provide for more time during the low
flow season, the time when most of the critical construction activities will take place .
Giving the bidding ~ontractors more time during the low flow season has
undoubtedly reduced bid prices and will likely reduce the potential for construction
claims. The contract time has been extended to 689 calendars from 499 calendar
days (an increase of 190 calendar days). For the time extension, the ENGINEER
will attend additional coordination and progress meetings ; provide additional resident
project representative services; respond to additional questions, and requests for
clarifications and interpretations; and provide additional management and
administration of the construction phase.
All other terms and conditions of the AGREEMENT of May 6, 1996 , as amended , remain in full force
and effect.
IN WITNESS WHEREOF , the parties hereto have executed this FOURTH AMENDMENT to the
AGREEMENT to be effective as of the date first above written .

Re: Plan for Augmentation of Conifer Corners
Job No. 159.6
Thank you for taking the time to talk with me about our desire to engineer
a plan for augmentation for a fairly small residential development located near
Conifer. The proposed subdivision will lie near the headwaters of North Turkey
Creek west of U.S. Highway 285 near Conifer. The plan in all likelihood will
use Ron Blatchley' s Mountain Mutual Reservoir Company water for
augmentation which is derived from changed rights in the Warrior Ditch and in
Soda Lakes. Approximately one to three acre-feet of consumptive use water will
be involved in the plan for augmentation.
Consistent with Martin and Wood's opinions on similar plans located in
the Bear Creek Turkey Creek water sheds and that such plans have not
warranted objection by the City of Englewood, it is our opinion that this plan
near Conifer would also not affect Englewood's McBroom Ditch water rights.
This is an opinion which you and the City of Englewood, of course, should
retain the right to determine on your own terms, perhaps with the help of an
outside engineer.

Subject
Dear Bill,
Allen Water Treatment Plant Improvements
Contractor' Proposal to Cose Layton Avenue
Please find attached to this Steve Thanner's letter dated February 5, 1998. In this
letter Centric/Jones Constructors requests permission to dose Layton Avenue
adjacent to the Allen Water Tzeatment Plant for the duration of the improvements
construction. We request that you review this request with Stewart Fonda and pass
on your recommendations to the appropriate parties.
COM has reviewed the Contractor's request and we agree that the closure of Layton
Avenue will be of benefit to the plant as well as to the Contractor. Ii the Contractor
is allowed to use only the areas designated for staging and construction in the
contract documents, the staging area will be quite congested and will have an
impact on the City's access to the plant. If Layton A venue can be used as a staging
area, better access to the plant and a less congested work area will be the result
Another point to consider that is not mentioned. in Centric/Jones' request is that
Layton will need to be closed several different times during the construction for
extended periods of time anyway in order to install pipelines. Centric/Jones is
preparing a drawing that would show their proposed work and staging areas, which
we will forward to you as soon as we receive it We recommend that this request to
dose Layton Avenue be granted.
If you have any questions with regard to this matter please do not hesitate to contact
me.
Sincerely,

Subject: Proposal to clo~e Layton Avenue
OenUemen:
___ t""' • .;j/.;j 1:::1 ......
As discussed al the p~n.~ction conference ye~tcrday, Centric-Jones would like tu propose
that I .ayton A venue, on the north perimeter of the Allen W1 l' entrance, be clnsed foT the entire
duration of the project construction period. We have rcvic:wed ~allowable contractor's staging
areas, ;4nd believe that our required storage areas for office trailers, enginoen o1lice trailer. tno1
mid equipment trailers, subcontractors' trailers, form yard. rebar. aud pipe: laydown areas, will
require ;ibom four t:im~ the allowable illca shown on sheet G-3.
Along with these requirements, we wiJI need an area for our major construction equipment
patkin.g, 1t11d empluyee parking. Also, when considering construction traffic such as concrde
uuck.s, pump trucks, delivery tr\h:k.s, aggregate stockpile.~. and plant ch.:mical deliveries, it seems
reasonable that closing La.ywu A venue to public traffic is ~ feasible solution to the inevitable
cong~1ion which will occur.
Centric-Jones will provide sufficient tc:mporazy security fencing and gates, along with required
ttaffi1.: signagc. Please review our proposal and advise if you concur. or if we sho·ulci meet to
discuss other altematives.
Sincerely;
