INTRODUCTION
The purpose of this memorandum is requesting the City Council conduct a public hearing for the
Well No.7 Rehabilitation Project 2024 — Phase 2.
BACKGROUND
The City of Dubuque budgets for and conducts routine well maintenance. The work includes
repairs and rehabilitation associated with the City's groundwater supply (wells, pumps, and
motors) including source water protection of the well field and the raw water transmission lines
from the wells to the treatment plant.
The City draws from both shallow and deep wells and each well should be inspected routinely or
when capacity drops. The current practice is to evaluate the capacity of wells annually and pull
the equipment and inspect the wells every 5 years, barring any known issues.
DISCUSSION
Well No. 7 is pumping below its design capacity and is pumping sand, which can lead to
premature wear and tear of pump impellers, possible plugging of the well transmission main and
increase overall electricity expenses.
During Phase 1 of the project, the well was taken out of service and inspected by Cahoy Pump
Service in December 2022, to determine what rehabilitation may be necessary along with a
completion of a condition assessment of the column piping, pump, and motor.
Cahoy's findings were as follows. A large volume of sediment was discovered at the bottom of
the well reducing the overall well depth by 488 vertical feet. The suction pipe and strainer were
missing and not attached to the pump intake. This could be for two reasons; they were either not
installed or could be at the bottom of the well in the 488 feet of sediment. The shafting,
couplings, column pipe and spider bearings also showed significant wear and tear, and most
notably, the pump was detached from the column pipe.
Based on Cahoy's findings regarding the sediment and the impact, the depth of sediment may
have on the well capacity, we are looking to bid removal of the sediment and conduct a pumping
drawdown test to determine the well capacity, followed by installation of a replacement pump,
motor and well appurtenances. Following sediment removal and the pump test, the city and
contractor will review the specified replacement pump and motor and confirm the pump and
motor sizing based on the available capacity of the well, including confirmation of the pump
depth, suitable sand prevention method, and create a future well maintenance schedule.
The scope and bidding documents have been prepared and are publicly advertised for bidding.
