CITY COUNCIL AGENDA ITEM
TO: MAYOR AND MEMBERS OF THE DENTON CITY COUNCIL
FROM: R.E. Nelson, Executive Director of Utilities
SUBJECT: CONSIDER APPROVAL OF THE PURCHASE OF AN AUTOMATED ALGAE
SWEEP FROM FORD W. HALL CO., INC. IN THE AMOUNT OF
$15,388.
RECOMMENDATION:
Staff recommends the purchase of an automated algae sweep from
Ford W. Hall Co.,Inc. to be installed on one final clarifier.
BACKGROUND\SU~4MARY:
The Wastewater Treatment Plant operations staff currently
spends a great deal of manpower and expense removing algae
from the final clarifier weirs to maintain hydraulic
uniformity and prevent short circuiting. An automated process
for removing algae has tremendous potential to reduce manpower
and chemical cost associated with this maintenance.
Additional benefits would also include improved safety by
eliminating slips and falls and by reducing the chemical
exposures.
The Denton operations foreman (Larry Taylor) recently visited
the Whites Creek WWTP (a 12 MGD facility) to observe the
actual installation and operation of the proposed automated
algae sweep. Based on his observations and conversation with
the Plant Supervisor (David Tucker), we believe the algae
sweep would be an economical alternative to our existing
method of weir cleaning and will provide a reasonable payback
for our operation.
PROGRAM/DEPARTMENT OR GROUPS AFFECTED:
City of Denton Citizens, Department of Denton Public utilities
FISCAL IMPACT:
Algae removal on final clarifiers costs the operation
approximately $4,212 per clartfier per year. Based on a
purchase price of $15,388 a pay back of 3 65 year would be
expected. ' ·
