MORAINE AVENUE &BEAVER POINT WATERLINE IMPROVEMENTS -BIDS:
CAP Construction Company submitted the only bid for the Moraine Avenue
and Beaver Point waterline improvements of $56,587.18 and $15,628.56
respectively ($72,215.74 total).This bid exceeded the engineer?s
estimate of $39,195 forthe Moraine Avenue waterline and $9,750 for the
Beaver Point waterline ($48,945 total).A detailed outline of the bid
submitted is attached to these minutes.
The Committee tabled its recommendation on the bid to allow Mr.Colwell
time to discuss with the State Department of Highways the base and
resurfacing requirements and to consult with CAP Construction Company
regarding its confirmation of the bid if the base course and resur
facing items were excluded.
WATER QUALITY ANALYSIS:
Consulting Engineer Walt Coiwell of DMJM—Phillips.Reister,Inc.pre
sented the attached analysis of two water samples from the Estes Park
system.Large cities that have complete chemical feeding equipment
feed lime to raise the pH level.This is not recommended for Estes
Park at this time.Mr.Colwell’s recommendation is to monitor the pH
level in the system closely and take what steps can be taken other
than chemical additions.
There being no further business,the meeting adjourned.

Subject:Colored Water
Dear Vic:
Enclosed is the chemical analysis report on the two water samples
taken from customers complaining of color in the water.
The color in the wash cloth was mainly from the 4.5 milligrams of
copper that it held.The wash cloth also held a significant amount of
zinc (0.80 milligrams).We have no immediate explanation for the concen
tration of these metals in the wash cloth.It should be noted that these
metals are widely used piping materials in domestic plumbing.
Because Estes Park’s Water this summer is mostly snow melt with very
little hardness (and very low total dissolved solids),the water is
aggressive and tends to dissolve (even if ever so slightly)any material
it comes in contact with.This is a normal consequence of soft water,thus
it is not unexpected to find minute quantities of pipe metals in solution
after the water has reached the end user.
The aggressiveness of the water is aggrevated by its low pH (6.21-6.57,
i.e.slightly acid).In individual cases stray electrical currents might also
cause electrolytic corrosion of customer’s plumbing which just compounds the
problem.
Very truly yours,
DMJM/PHILLIPS—REI ER—HALEY,INC.
