• Remove debris from influent and effluent spring water

• Repair deteriorating concrete raceways

• Replace bird control netting

• Expand administrative workspace, shop and storage buildings

Phase 1 Construction 2012

Phase 2 Construction 2013

Site DesignPriorities:

• Retain gravity flow water source• Provide pathogen free water for incubation and indoor rearing• Install a vat size and quantity that allows an even distribution of fish

when moved into outdoor raceways• Provide ability to rear fish indoors until they were large enough for

marking

Challenges with space for hatchery building:• Building requires a large footprint with little land available

• Back wall of hatchery building supports the entrance road• Need to maintain access between raceways and hatchery building for fish

tankers• Creating a vat room layout that included enough space for the vats while

maintaining a clear separation of the two different stocks

Existing Indoor Rearing:

Total number of vats = 21

Vat dimensions: 8’L x 2.5’W x 2.5’D

Rearing volume per vat: 37.5 ft3

Max flow for incubation = ~ 3 cfs

Max flow per vat = 47.6 gpm

Max density index = 0.88 lbs/cf/in

Max flow index = 0.70 lbs/gpm/in

Approx. eggs/fry per vat = ~ 50,000

Split inventory – eggs & fry

Size at transfer to outdoor raceways = 1,000 fpp

Indoor Rearing Design Criteria:• Total number of vats = 38 (16 OFH, 22 PFH)

• Vat dimensions: 50’L x 4’W x 3.5’D

• Rearing volume per vat : 552 ft3

• Max flow for incubation = 18 cfs

• Max flow per vat = 212 gpm

• Max density index = 0.35 lbs/cf/in

• Max flow index = 0.85 lbs/gpm/in

• Approx. eggs/fry per vat = ~ 55,000

• Entire inventory received as eyed eggs

• Target size at transfer to outdoor raceways = 90 fpp (at marking)

Intake & Filter Building:• Water source → Niagara Springs

middle pool via RVTC canal• Maintain gravity flow • No in-stream work (BRS)

• Flow meters per IDWR requirements

• Two sets of drum and disc filters for different size debris

• 2 drum filters – 100 µm• 2 disk filters – 30 µm

• Full 18 cfs can be passed through either set of filters without affecting operation

• Filters and backwash spray system operated on timer or head differential

UV System:• Pathogens of concern:

• Infectious Hematopoietic Necrosis (IHN)• Infectious Pancreatic Necrosis (IPN)• Furunculosis• Enteric Red Mouth (ERM)• Viral hemorrhagic septicemia (VHS)• Whirling Disease (WD)• Cold Water Disease (CWD)• Nucleospora salmonis

• UV doses for inactivation of these pathogens → 5,000-150,000 mJ/cm2

• All but IPN inactivated at 40,000 mJ/cm2 or below

• IPN requires system that is 3-4 times larger

• Design dose = 60,000 mJ/cm2

(minimum dose at end of lamp life)

• Total of three UV vessels– 2 for operation, 1 backup

• UV system alarming:– Lamp failure– Low dose

• Generator backup for filter building and UV system

UV System (continued)…

Alarming/SCADA

Vat Room• Size of vat room:

– Old vat room = 1,340 ft2

– New vat room = 18,500 ft2

• Number of rearing vats:– Old vat room = 21 vats– New Vat room = 38 vats

• Total rearing volume:– Old vats = 750 ft3

– New vats = 21,000 ft3

• Natural lighting

Additional Rooms

• Feed Room– Storage of palletized feed– Workbench for weighing

feed

• Egg Room– Receive, enumerate and

disinfect eyed eggs– Laboratory use

• Boot Room– Vat room gear storage

• Mud Room– Remove outdoor gear– Water fountain– Restroom

• Visitor Room– View of vat room– Display tank– Information, brochures, etc.– Water fountain– Restroom

Administrative Area

• Office– Manager’s office– 3 Workstations– Seasonal room

• Conference Room– Break/lunch room– School tours– Meetings

Phase 2

• Raceway water intake modifications

• Outdoor raceway modifications

• Bulk feed storage modifications

• Bird netting modifications

• Install discharge traveling screens

• Construct shop building

• Construct storage building

Raceway Water Intake• Leaf debris during the spring and

fall plugs head screens and tail screens on raceways

• Can be unpredictable - frequent monitoring by staff during peak loads and stormy weather

• Install stainless steel inclined traveling screens to remove most debris

• Operate on automated schedule or head differential

• Traveling screen openings the same as raceway screens

Raceway Modifications• Total of 19 raceways

– 14 original from 1966, 5 additional in 1993-1994 modification

• Repair or replace raceway walls (original 14 raceways)– Concrete cracking and spalling – Rusting and deterioration of keyways

• Replace steel keyways in original 14 raceways with stainless steel keyways to address corrosion

• Install additional keyways in all 19 raceways– Keyways currently at 100 foot intervals– Install additional stainless steel keyways at 50 foot intervals

Traveling Bridge Replacement

• Split large traveling bridge into 2 smaller bridges– Reduce maintenance on bridges

• Eliminate racking, derailing• Switch to more reliable direct drive

power system

• Allow for bird netting supports on raceway wall

• Replace all feeders

Bulk Feed Storage• Raise height of bulk feed

storage hoppers to allow personnel to perform maintenance more easily

• Raise height of feed conveyor system to eliminate the risk of head injuries

Bird Netting• Install support system on

raceway wall to reduce sag

• Replace existing 2-3” mesh bird netting with ¾” mesh netting

Discharge Traveling Screens• Issues with large mats of algae

breaking loose and leaving ponds– NPDES concerns– Plugging RVTC screen

• Two discharge points: Niagara Springs Creek and RVTC canal

• Install stainless steel inclined traveling screens to remove debris

• Similar design and operation to system at raceway intake

Shop Building• Bigger shop area

– 640 ft2 vs. 880 ft2

• Gear room – Store gear used in raceways

• Restroom• Drinking fountain

• Mechanical room• Lab room

– NPDES sampling equipment– Pathology

• Storage bay with mezzanine• Vehicle Bay

Storage Building• Lawn equipment storage

• Large center bay for 10-ft raceway screen storage

• Other miscellaneous storage

• Covered, fenced outdoor storage area

• Bulk fuel storage

Project Summary

Address Operational Constraints• Enlarge incubation and early rearing for improved fish health

• Reduce maintenance and repair costs

• Improve predator control

• Enlarge office workspace

Incorporate Modern Fish Culture Technology• Water filtration and UV disinfection

• Improve bio-security

• State-of-the art alarming and standby power

• Debris removal screening
