The construction of the City of
Hollister Waste Water Treatment Plant was completed in
November 1998. The 3.2-MGD plant has two (2) oxidation
ditches, four (4) clarifiers, three (3) sand filters, three
(3) sludge-holding tanks, ultraviolet disinfection and a
state of the art SCADA system.
The Kruger designed SCADA system allows the plant to be
staffed during day hours only. If a problem arises, the
system will page the plant personnel, and they can call in
from home via lap top computer and either fix the problem or
determine whether they need to come in. One of the many
features the system has is dissolved oxygen control in the
ditches, this allows for rotors to be turned on and off,
only when needed. This saves big money on power costs.
The plant has a staff of two operators, both are state
certified with an A & B license. The plant has a stringent
.5mg/1 phosphorus limit, which has been met without
violation.
Sludge is spread over an area of 7,500 acres of farmland located
about ten (10) miles from the Waste Water Treatment Plant. The
Missouri Department of Natural Resources guidelines controls sludge
spreading. |
