Calculators

• Drain Cut Sheet Aid (175KB XLS) — A MS-Excel spreadsheet for developing cut sheets for drainage systems. (Designed by NRCS and University of Minnesota Extension)
• Online Drainage Calculators Calculators for pipe size, area drained, flow rate calculator/converter, and drainage profitability analysis.
• Spreadsheets (ESTIMATE, SLOPE, and TILT) — Send an email request to Galehouse Drainage, Inc.
  • ESTIMATE: Calculates cuts and draw a profile for given stations, elevations, and grades. Calculates required slopes for different pipe materials. Prepares an estimate using your costs.
  • SLOPE: Helps determine how to increment the main/collector size for a pattern drained field with user specified lateral lengths. Determines slope needed for various main sizes as successive lateral flows are added. Also calculates required slopes for different pipe materials.
  • TILT: Displays the error created in the laser system if the machine tilts to the side

Maintenance of Drainage Systems

• Management of Drained Fields — Ontario Ministry of Food, Agriculture & Rural Affairs
• Drain Problems — Ontario Ministry of Food, Agriculture & Rural Affairs
