Introduction:
The Koontz Lake Regional Sewer District (KLRSD) is seeking an
IDEM Class II, or above, Wastewater Plant Operator for their Aero-Mod extended aeration Clean Water Treatment Plant.
The plant is located south of Koontz Lake in the northeast corner of Starke County and the northwest corner of Marshall County
on County Road 1175 E (plant address is 7315 N. 1175 E., Walkerton, IN 46574). An NPDES permit has already been obtained.
The collection system is a low pressure sewer system comprised of 512 grinder pumps, 90,000 linear feet of force main and
air release valves and will serve 900+ households and 30+ small businesses.
The collection
system and treatment plant are currently under construction with completion anticipated in early Fall 2011. The selected Operator
must be available for start-up operations at that time.
Clean Water Plant:
The
plant is an Aero-Mod extended aeration facility (see http://www.aeromod.net/ for more information). The plant is designed for an average daily flow of 219,100 gpd. It is estimated that existing
summertime flows will be in the range of 120.000 to 180,000 gpd. During the colder months, flow may be in the 80,000
to 120,000 gpd range since some homeowners are summertime residents only. Due to this possible flow variation, the plant
has an option whereby one of its two aeration "trains" can be taken off-line during low flow periods in order
to keep suitable biomass alive during the colder months. Each train, however, can handle sustained peak flows equal
to 3 times its average daily flow, if and when needed. There are no main influent pumps but there is an effluent pump station
to discharge the plant's "clean water" to Robbins Ditch which 3,500 feet distant from the plant. All waste
flow reaches the plant by low pressure force main via 512 Environment-One grinder pumps. Flow through the plant
is completely by gravity. Retractable stainless steel diffusors are provided as well as airlift pumps for sludge withdrawal
from the clarifiers. Sound-proof blowers are manufactured by Roots and are mounted on a concrete pad inside of
the unheated blower building. A natural gas, Kohler emergency generator is furnished. A heated control bulding and a
heated workshop are being built for Operator use. The workshop will be shared with the Collection System Operator. Outside
lighting and fencing is also part of the facility.
Sludge Digestion & Dewatering:
A large aerobic digester with decant capability is provided. Submersible pumps will transport sludge volumes from the
digesters to a Blue River Technologies (http://www.blueriverdewater.com/container4.htm ), geotextile, sludge dewatering bag system. A polymer pump and static mixer to flocculate the sludge prior to discharge
into the bag is located in the control building. A 30 CY roll-off container will be furnished which will normally reside
on the concrete dewatering pad. Sludge can be processed year-round on whatever schedule is determined by the Operator.
It is estimated that only one or two bags per year will be needed. Bag and polymer costs as well as the landfill
trucking costs will be borne by the District.
Laboratory:
There is no laboratory
on the premises. The operator will be responsible for coordinating, completing and submitting all sampling requirements
per the District's discharge permit; e.g., TSS, CBOD5, NH3N, pH, D.O., and e coli. The
operator will further be responsible for making sure that all testing and recording be performed properly to insure accurate
composite sampling criteria. The plant will have an influent, Doppler flow meter attached to the force main with daily
electronic storage capability. At the effluent end, an open channel, V-notch weir-type, ultrasonic flow meter with capability
to store at least 90 days of daily flow readings is also provided. Per prior IDEM approval, all final effluent sampling
can be done at the plant and not at the plant's actual discharge point which is 3,500 feet downstream.
The
costs for collecting, storing, transporting and testing all IDEM required tests will be included in the operator's submittal.
If a respondant also believes that additional process testing is needed so as to help keep the plant performing at its peak
treatment efficiencies, then these costs shall be included as well. Such tests might be SVI's, further TSS's, etc.
No additional lab testing shall be paid for by the Distrsict other than those identified in the respondant's proposal unless
prior written approval of the District Board is received. A paper chart recorder is not provided nor required by IDEM.
Coordination of sample pick-up or drop-off will be the Operator's responsibility. A copy of the District's NPDES permit
is available on request.
Disinfection:
A 20 or 24 bulb, open channel, Glasco,
UV disinfection system is provided. Manual cleaning of the bulbs is required. Per the discharge permit, disinfection
is needed only from April 1 through October 31.
Effluent Pump Station:
After
disinfection, treated flow is sent to the wetwell of this conventional style, submersible lift station which is comprised
of two, 10 HP pumps which operate on the usual lead, lag and daily alternate cycles. Controls are fully enclosed in
a stainless steel, NEMA 4X enclosure. Certain station parameters are included within the minimal SCADA system of the
plant.
Qualifications Requirement:
The respondent must hold and maintain
an IDEM Class II Wastewater Plant Operator, or above, and furnish a copy of certification. The respondent must also sufficiently
demonstrate, with documentation or references, that they are properly qualified to do this work. Such demonstration
should include resumes, copies of certifications, etc. in order to meet this requirement. Direct experience in performing
a similar function or municipal public works sewer experience is highly desirable.
General Responsiblities:
The
Teatment Plant Operator will be required to monitor operating conditions of the Clean Water Plant making adjustments or performing
repairs to enable optimal performance of the system. The Operator will perform all sampling and reporting as required by IDEM.
The Operator must be able to troubleshoot facility problems and take necessary corrective action. The Operator will perform
routine maintenance functions and keep appropriate maintenance records.
The District will require that
the plant be visited at least 5 days per week to assure proper function of the system. A minimal SCADA system at the
plant for emergency notification of certain critical functions is provided. The Operator will be the primary contact for all
system alerts and must be available for response 24/7.
The Operator must be available by phone at all times
and must be able to respond to equipment emergencies 24/7. The cost of any such phone shall be incidental to the contract
and will not be paid for by the KLRSD as a reimbursable.
The Operator will be responsible for any damage
to personal property or KLRSD property while performing the duties of the job.
The Operator must be able
to lift or move 50 pounds in order to perform various duties.
The Operator may be requested to attend an

The Operator will be required to submit
