2. Water Supply Planning
Ash Hammerbeck, Project Manager summarized previous work session discussions regarding ground
storage water tanks and water tower storage units. Project Manager Hammerbeck outlined the goals
for the meeting, noted future meeting dates, design and budget updates, and noted initial facility
capacity construction with estimated max day demand of 1.44 MGD, with future build out estimated
max day demand of 6 MGD. Project Manager Hammerbeck emphasized flexibility and expandability
as key goals in facility selection and construction. Council and staff discussed filter cell size and flow,
population, expandability, and capacity. Project Manager Hammerbeck and Council discussed
operation of filter cells as independent units, growth projections indicating the need for 3 cells or 3
MGD per population growth, recognizing symmetry of growth within complete facility including tank
facility on lower lever, back wash tanks, pump room, and detention tank. Engineer Steve Hegland and
Council reviewed as cells are added, tanks will need to be increased for volume of finished water, and
washed water storage. Council and staff discussed each time a proportional addition is built onto the
facility, cost savings can be realized in future construction costs, by building additional facility space
for 3-cell filter capacity in initial construction, with no detriment in having larger tanks. Project Manager
Hammerbeck reviewed three treatment process of options including size, aeration tower, chemical,
and filtration, pros and cons consideration, and safety aspects of each treatment facility option. Project
Manager Hammerbeck reviewed water tower volume, clear well storage, long-term storage needs, and
cost considerations.
