Intake Screen Sizing Wizard

All Cook Legacy screens are custom designed and built based on your site-specific needs. This tool will provide a starting point for discussions with Cook Legacy. Please fill in any information that you know. Roll your mouse pointer above the TooltipHold your mouse over each tooltip for further information and guidance. icons for design guidance.
 

Step One: Please tell us about you and your project. Fill in as much as you want, but we’ll need an email to get you results.

Step Two: Screens are sized based on the volume of flow, the required filtration, and site-specific constraints.

Total Flow:
 TooltipSelect the projected plant flow. Typically, size based on a conservative projection.
 
Water Body:
 TooltipIdentify the water body from which you will be withdrawing.
 
Screen Qty:
Basic Sizing Information:
 TooltipUsing the table below, select the quantity of screens necessary. We will help optimize the size and quantity, but this is a starting point.

Step Three: Please identify any technical features or site specific concerns we need to address.

Technical Details:  
Required Filtration for Process:
 TooltipAt some sites, the process requirements dictate the slot width. If that is the case, indicate the maximum allowable particle. If other factors such as fish protection dictate slot, leave this blank.
 
Water Quality:
 
Maximum Water Depth:
 TooltipWater depth often varies widely. For the maximum depth, choose the high water level at which you want the air burst (if any) to function. For minimum water depth, choose the minimum depth at which the system will operate.
 
Minimum Water Depth:
 TooltipWater depth often varies widely. For the maximum depth, choose the high water level at which you want the air burst (if any) to function. For minimum water depth, choose the minimum depth at which the system will operate.
 
Distance between pump house and screen:
 TooltipPlease indicate the distance between the pump house and the screen. The run of pipe between the pump house and the installed screen is essential to the design of the AirBurst System.
 
Regulations:
 TooltipThese are the most common regulations that we design for. Choose "other" if there is some other known regulation governing the velocity profile. Choose "N/A" if there are no governing regulations and you simply want a screen that won't clog.

If "other", please identify:
 
Other Design Concerns (select
all that apply):
 TooltipSeveral of these concerns are present at all sites. Use your best judgment, and when in doubt add the concern. 
Biofouling Navigable Water Way
Frazil Ice Significant Debris Events
Sheet Ice Stagnant Water
 
Orientation and Connection:  
Orientation:
 TooltipChoose vertical if the outlet is pointing down. This is common when connecting to a trenched pipe or manifold. A horizontal connection is sometimes used when connecting to a pipe, or when mounting to a wall.
