ACKNOWLEDGEMENTS 

Prototype development and testing of the alternative water intake structure was a 

cooperative project between the Alaska Department of Transportation and Public 

Facilities (ADOT&PF), Northern Regional Office, and the Alaska Department of Fish 

and Game (ADF&G), Habitat and Restoration Division, Northern Region. ADOT&PF's 

support for applied research is commended and gteatly appreciated. The new water 

intake structures address both ADF&G's fish intake, entrapment, and impingement 

concerns and ADOT&PF's operational need for light-weight, readily-deployable 

structures.

Abstract - Light-weight, easily-deployable, four-inch (101.6 mm) and six-inch (152.4 mm) 

screened aluminum water pump intake cylinders were evaluated for risk of fish entrainment, 

entrapment, and impingement. The intake cylinders incorporate an off-round design, solid 

bottom, 0.25-inch (6.35 mm) outer screen surface, and a perforated inner aluminum sleeve. The 

cylinders are designed to rest on the channel bottom in riffle-sections which weaker-swimming 

fish typically do not occupy. The intake cylinders align longitudinally with the channel current 

to facilitate self-cleaning and flushing. Design flows for the four-inch (101.6 mm) and six-inch 

(152.4 mm) pumps were 600 gpm (37.85 Us) and 1,200 gpm (75.7 Us), respectively. Approach 

water velocities for the second-generation six-inch (152.4 mm) and f~st-generation four-inch 

(101.6 mm) pump intake cylinders were non-detectable across the outer screen surface using a 

pygmy gurley velocity meter.

INTRODUCTION 

In 1995, the Alaska Department of Transportation and Public Facilities (ADOT&PF), 

Dalton Highway Maintenance Section, and the Alaska Department of Fish and Game 

(ADF&G), Habitat and Restoration Division, Northern Region, initiated a two-year 

cooperative research effort to develop alternatives to traditional box water intake 

structures. This research was needed to address the identified problems with traditional 

screened boxes and a joint desire to protect fisheries resources consistent with the 

requirements of Alaska Statute 16.05.870. 

Water intake structures used by the ADOT&PF and other contractors typically are 

constructed of heavy-gauge angle iron with galvanized mesh screen. For typical water 

intake volumes, these structures are approximately 3 foot (0.91 m) by 3 foot (0.91 m) by 

3 foot (0.91 m) in dimension. In shallow waterbodies the boxes can only be installed in 

naturally occurring deep pools or excavated sumps within the stream channel. Yet 

placement of the boxes in these locations increases the risk of fish entrainment, 

impingement, and entrapment because most young-of-the-year salmonids occupy 

backwater and low velocity pool habitats. Traditional water intake boxes are heavy and 

cumbersome to move, generally requiring two people to off-load or reposition. Due to 

recent budget cuts to the Northern Region ADOT&PF, only one equipment operator is 

available for every 40 miles (64.4 km) of road. The traditional screened box enclosure is 

no longer practical for existing staffing levels. 

BACKGROUND 

Water withdrawals from fish-bearing waters pose potential problems to both adult and - 

juvenile fish swimming in the proximity of 4 intake structure. Although most water 

withdrawals use a screened intake (rock guard) to avoid entraining gravel or debris, the - - 

relatively large mesh size allows eitrai&ent of fiy and juvenile fish into the pump. At 

high flow rates, the approach velocity across the screen surface can draw fish up against 

and hold them against the screen surface, resulting in suffocation or physical damage. 
To avoid impacts, particularly to newly-hatched juveniles and weak-swimming fish, 

ADF&G encourages the following in-priority alternatives to instream, screened water 

intake structures: 

t identify and withdraw water fiom non-fish bearing waterbodies; 

t use well points, off-channel sumps, and infiltration galleries; and 

t schedule maintenance and construction activities during time periods when water is 

plentiful and younger life-stages of fish are not present. 

In many instances there may not be an alternative to instream water withdrawal. In these 

instances, various intake design criteria have been developed by other investigators, 

largely as off-shoots of fish exclosure designs - for water irrigation intakes - based on 

vertical screen faces. A common criteria adopted by the Department of Fisheries and 

Oceans Canada specifies a gross screen area of 10ft.~ (0.929 m2) for each cubic foot per 

second (cfs) (28.3 Us) pumped for manually cleaned screens. All screens must have at 

least 50% open area to reduce head loss and minimize velocities at the screen opening 

(Clay, 1961). 

After an extensive literature review, ADF&G developed five different maximum screen 

mesh size and approach water velocity criteria for various fish species and life stages 

(Sundberg, 1986). These criteria are presented in Table 1 and range from a conservative 

approach velocity of 0.1 fps (3.048 cmls) and a 0.04 inch (1.02 mm) mesh screen for 

newly-hatched whitefish fry to a fairly liberal 2.0 fps (60.96 cds) approach velocity and 

0.25 inch (6.35 mm) mesh hardware cloth for adult salmon, whitefish, and Dolly Varden 

(Arctic char). ADF&G's current criteria (1986 to present) are based on the size and 

swimming abilities of the fish species present and are enforced through Fish Habitat 

Permits issued under AK Statute 16.05.870 ... 16.05.900. In most instances, multiple 

species and size classes of fish are present in a waterbody and the most restrictive criteria 

is used. 

Several problems have been identified by ADOT&PF and other contractors with use of 

the large screened intake boxes: 

t the physical shape of traditional screened boxes requires operators to place the box in 

habitats known to attract and hold vulnerable fry and juvenile fish. Because this 

occurs, ADOT & PF and other contractors are required to use the more restrictive 

criteria for juvenile fish. It also places juvenile fish at increased risk; 

t in shallow streams, the large size of traditional screened boxes requires subexcavation of the stream channel bottom to completely submerge the box. This 

results in additional habitat degradation and potential channel alteration; 

t large screen faces oriented perpendicular to the water flow are subject to fouling with 

organic debris and require fiequent cleaning; and 

t large-screen box structures are difficult for one person to physically handle. 

Six-Inch Pump -First Generation. The first generation six-inch (152.4 mm) diameter 

pump intake prototype was a 4 ft. (1.22 m) long, eight-inch (203.2 mm) diameter, slotted 

Schedule 40 aluminum pipe placed on-center within a 1.6 foot (48.77 cm) diameter, 114- 

inch (6.35 mm) stainless steel mesh-covered outer sleeve (Figure 1). Inner pipe slot and 

hole dimensions and spacing were optimized to disperse water flows equally across the 

distal to proximal length of inner sleeve while maintaining hydraulic capacity. Cut out 

dimensions for the inner pipe sleeve are shown in Appendix A in both ft./lb. and S.I. 

units. The distal end was capped to prevent fish that might congregate in the back eddy 

that forms at the downstream end of the intake cylinder from impinging on the screen 

surface. 

The first prototype was taken to ADOT&PF's Northern Region annual foreman's 

meeting in Valdez in Spring 1997 for critique and evaluation. Several modifications were 

recommended by ADOT&PF field staff and incorporated in the second prototypes.

Six-Inch Pump - Second Generation. The second generation six-inch (152.4 mm) 

pump intake prototype was constructed in 1997. This prototype consisted of a 4.0 ft. 

(1.22 m) long, six-inch (152.4 mm) diameter slotted aluminum pipe (Schedule 40) placed 

off-center within a 1.3 ft. (39.62 cm) diameter partially squashed 114-inch (6.35 mm) 

mesh covered outer sleeve (Figure 2). The center pipe was placed 1.3 in. (33.02 mm) 

above a flat, solid aluminum plate 0.9 feet (27.43 cm) wide by 4.0 ft. (1.22 m) long. The 

center pipe was separated from the outer screen along its sides and top by 0.35 ft (10.67 

cm). The effective outer mesh face was 2.75 ft. (0.84 m) by 4.0 ft. (1.22 m) with an 

additional screen opening of 0.978 ft.' (908.56 cm2) at the proximal end. Three-by-three 

stainless steel wire mesh (wire diameter = 0.08 in.(2.03 mm); 0.253 in. (6.43 mm) 

opening) with an effective open area of 57.6% was used for the outer screen covering. 

Total effective outer screen area was 11.98 ft.2 (1.1 1 m2). Cut-out dimensions for the 

inner pipe sleeve are shown in Appendix B in both ft./lb. and S.I. units. Deployed weight 

was 71 lbs (32.21 kg).

Four-Inch Pump. A four-inch (101.6 mm) pump prototype also was constructed in 

1997. This prototype consisted of a 4.0 ft. (1.22 m) long, four-inch (101.6 mm) diameter 

slotted aluminum pipe (Schedule 40) placed off-center within a 1.05 ft. (32 cm) diameter 

partially squashed 114-inch (6.35 mm) stainless steel mesh-covered outer sleeve (Figure 

3). The center pipe was placed 0.75 inches (19.05 mm) above a 0.85 ft. (25.91 cm) wide 

by 4.0 ft. (1.22 m) long flat, solid aluminum plate. The center pipe was separated fiom 

the outer screen along its sides and top by 0.35 ft (10.67 cm). The effective outer mesh 

face was 2.2 ft. (0.67 m) by 4 ft. (1.22 m) with an additional screen opening of 0.669 ft.2 

(621.50 cm2) at the proximal end. Three-by-three stainless steel wire mesh (wire 

diameter = 0.08 in. (2.03 mm); 0.253 in. (6.43 mm) opening) with an effective open area 

of 57.6% was used for the outer screen covering. 

Total effective outer screen area was 9.47 ft.2 (0.88 m2). Cutout dimensions for the inner 

pipe sleeve are shown in Appendix C in both ft.1lb. and S.I. units. Deployed weight was

Field Test Methodology. Prototypes were field evaluated for pumping capacity and 

screen approach water velocities. All testing was completed by ADF&G and ADOT&PF 

staff at the Fairbanks International Airport float plane pond. 

Approach water velocities were measured immediately adjacent to the outer screen mesh 

surface with a Teledyne Gurley Model 625F Pygmy water current meter rated to measure 

velocities between 0.05 fps (1.5 cds) to 3.0 fps (91.44 cds). 

A six-inch (152.5 mm) by six-inch (152.4 mm) Gorman-Rupp self-priming centrifugal 

pump, Model CE6A60-4039D diesel pump was used for testing the six-inch (152.4 mm) 

diameter first and second generation pump intake cylinders. The cylinder was tested at a 

rated pumping capacity of approximately 1,200 gpm (75.7 Us). 

The four-inch (101.6 mm) diameter first generation pump intake cylinder was tested 

using a Wacker PT4B gasoline centrifugal trash pump with a maximum rated capacity of 

740 gpm (46.68 Us). Estimated rated pumping capacity during testing was 600 gpm 

(37.85 Us). 

Performance curves for both pumps are provided in Appendix D. 

RESULTS 

First Generation Six-Inch Cylinder: The first generation six-inch (152.4 mm) pump 

intake prototype was field tested on July 23, 1996, at the Fairbanks International Airport 

float plane pond. Approach water velocities were non-detectable with the pygmy gurley 

water velocity meter at the proximal end of the cylinder and within the center one-third of 

the cylinder. 

Approach water velocities at the distal end adjacent to the 1-518 inch (41.28 mm) circular 

holes in the inner pipe sleeve fluctuated between below detection to a maximum of 0.17 

fps (5.18 cds). 

Water was pumped through the screened intake for approximately 40 minutes. During 

this period, slight organic fouling of the screen surface was noted on the bottom half of 

the distal 113 segment. 

Second Generation Six-Inch Cylinder: The second generation six-inch (152.4 mm) 

pump intake prototype was field tested on August 25, 1997. These tests also were 

conducted at the Fairbanks International Auport float plane pond. Approach water 

velocities across the entire screen surface were non-detectable with the pygmy gurley 

water velocity meter. 

A 2 ft. (60.96 cm) by 1 ft. (30.48 cm), 1.5 millimeter thick plastic garbage bag was placed 

over the outer screen in the proximal 113 segment, the middle 113 segment, and the distal 
113 segment of the intake cylinder. The plastic bag reduced the effective screen surface 

by approximately 17%, yet did not adhere finny to the screen surface in the proximal 113 

and middle 113 segments. In the distal 113 segment, the plastic bag adhered to the screen 

surface but dislodged readily when tugged gently by hand. To further evaluate the distal 

113 segment, grass blades approximately 0.5 ft. (15.24 cm) long were placed against the 

screen. Inducing a slight current (running my hand underwater or moving through the 

water column adjacent to the intake cylinder in my hip boots) washed the grass blades off 

the screen surface. 

The cylinder was elevated to the water surface so that the top of the cylinder was just 

covered by water. This test was designed to mimick actual field conditions with a 

maximum channel water depth of 1.3 ft. (39.62 cm). At full pumping capacity, no 

cavitation was observed. 

Water was pumped through the screened intake for approximately 25 minutes. Although 

the float pond had some floating and benthic organic debris (leaves, sedges, and upland 

grasses), no organic fouling of the screen surface was noted during the test period. 

First Generation Four-Inch Cylinder: The four-inch (101.6 mm) pump intake .- - prototype also was field tested in August 25, 1997, at the Fairbanks International Airport 

float plane pond. Approach water velocities across the entire screen surface were non- A A A 

detectable with the pygmy gurley water velocity meter. 

A 1.5 ft. (45.72 cm) by 1 ft. (30.48 cm), 1.5 millimeter thick, plastic garbage bag (a 

portion of the original plastic bag used in the six-inch test) was placed over the outer 

screen in the proximal 113 segment, the middle 113 segment, and the distal 113 segment of 

the intake cylinder. The plastic bag reduced the effective screen surface by 

approximately 16%, yet did not adhere firmly to the screen surface in any of the 

segments. A sweep of the hand underwater near the cylinder readily swept the plastic bag 

away kom the screen surface and it floated away in the water column. To further 

evaluate the cylinder, grass blades approximately 0.5 ft. (15.24 cm) long were placed 

against the screen. Inducing a slight current (running my hand underwater or moving 

through the water column in my hip boots) washed the grass blades off the screen surface. 

The cylinder was elevated to the water surface so that the top of the cylinder was just 

covered by water. This test was designed to mimick actual field conditions with a 

maximum channel water depth of 1.05 ft. (32 cm). At full pumping capacity, no 

cavitation was observed. 

Water was pumped through the screened intake for approximately 20 minutes. Although 

the float pond had some floating and benthic organic debris (leaves, sedges, and upland 

grasses),io organic fouling of the screen surface was noted during the test period. 
DISCUSSION 

The cylindrical water intake structures are designed for installation in shallow, swift 

portions of flowing waterbodies which Group A and B fiy and juvenile fish typically do 

not use as preferred habitats. The cylinders are designed to align parallel with the stream 

current. This maintains flushing flows along the length of the screen thereby minimizing 

fouling and potential impingement of fish against the screen surface. 

Correctly positioned in portions of flowing waterbodies where Group A and B fiy and 

juvenile fish are not present, the 114 inch (6.35 mm) screen meets ADF&G's mesh 

requirements for Group C (yearling), D, and E fish. Installation of the intake cylinder in 

waters containing Group C young-of-the-year coho, chinook, sockeye, or Dolly Varden 

(Arctic char) immediately after their emergence from the gravels in the spring will require 

wrapping the cylinder with 0.1 in. (2.54 mm) mesh hardware cloth to prevent entrainment 

of fish through the screen. Installation of the intake cylinder in pools or sluggish waters 

containing Group A and B fish requires wrapping the cylinder with 0.04 in. (1.02 mm) 

hardware cloth. This will reduce the effective screen area. Further testing is needed to 

evaluate impacts on pumping rates and effective approach water velocities using smaller 

mesh sizes. 

FLTTIJRE DEVELOPMENT AND TESTING 

A third generation six-inch (152.4 mm) diameter pump water intake cylinder has been 

constructed using 118 inch thick aluminum pipe in lieu of the Schedule 40 pipe used in 

the first and second generation prototypes. All other design criteria for the third 

generation cylinder were identical to the second generation cylinder. Deployed weight of 

the third generation cylinder is 25.4 lbs. (1 1.52 kg). Field testing will occur in Summer 

1998. 

Prototype units have been deployed to ADOT&PF field maintenance camps for further 

testing in 1998. Additional protypes using a 0.1 inch (2.54 mm) mesh outer screen 

surface will be developed in 1998 and evaluated. We are attempting to obtain a velocity 

meter with a lower minimum detection limit and greater precision to complete additional 

testing in 1998.
