FROM: BRUNO RUMBELOW, CITY MANAGER
MEETING DATE: SEPTEMBER 5, 2023
SUBJECT: EMERGENCY REPAIRS TO AERIAL SANITARY SEWER AND
APPROPRIATION ORDINANCE
RECOMMENDATION: City Council to consider approving the contract for emergency sanitary
sewer aerial crossing repairs with Wright Construction Company and
approval of an ordinance appropriating funds.
FUNDING SOURCE: Upon approval of the attached ordinance, funds will be available in the
Utility Enterprise Fund in the estimated amount of $227,000.
BACKGROUND: At the end of July 2023, a leak was discovered on a 15" cast iron aerial
sanitary sewer crossing near Horseshoe Trails. This occurred when the
creek eroded around the creek bank at sewer crossing and broke the
pipe. The City's utility crews made a temporary repair in anticipation of this
aerial crossing replacement. There are currently two parallel 15" aerial
crossings at this location, as stated, one has already broken and the other
is in a similar condition for failure. We are proposing replacing both 15"
cast iron crossings with a new single 21" PVC crossing within a 30" casing
pipe with related appurtenances needed for the construction.
Staff has been working with Wright Construction to scope and budget an
emergency replacement of this sewer aerial crossing. Wright Construction
has just completed three other aerial crossing repairs earlier this year with
excellent results. This new crossing will be similar in scope to the others.
Wright Construction has submitted a proposal based on time and
materials in the amount of $203,796.33 for repairs to the sewer crossing.
Staff has also included $22,417.59 or 11 % in construction related costs
(5% construction contingency, 4% inspection and 2% materials testing).
This brings the total construction phase appropriation to $226,213.92
(rounded to $227,000).
Staff recommends approval.
