8. Basic Tile Drainage Design Concepts:
⢠Topography â determines layout
⢠Outlet â necessity that can determine feasibility
⢠Coefficient â how much water the system can remove in
24hr period (influences main sizing, influenced by soils)
⢠Spacing â largest cost variable, strongly correlates to
efficacy, influenced by soils
⢠Tile â perforated, narrow slot, filtered
9. Why Tile?
⢠Better root structure
⢠Less compaction
⢠Increase in yield
⢠Less risk of major loss
⢠Less yield variability
⢠Environmental benefits
10. How tile works:
⢠Excess water in soil profile (Gravitational Water)
percolates down to restricted layer and causes water
table to rise
⢠Hydraulic pressure of water table causes water to seep
into perforations in pipe
⢠Water flows down pipe to outlet

12. Why is this important?
Plant roots die in
absence of oxygen!
32. Precision Land Solutions
⢠Started in 2007 after 10 years of experience in farm
management and tile drainage installation
⢠Focus on quality, expertise as a solutions provider
⢠Initially started 1,500 acres/yr; now 6,000+

47. Tile Drainage - Environmental Benefits
⢠Reduced surface runoff
⢠Improved soil health
⢠Green Benefits
48. Tile Drainage - Environmental Benefits
⢠Reduced surface runoff
â Tiled land acts as a buffer to rainfall, gives water time
to percolate into a soil profile and slowly be released
to streams (Van Vlack/Norton, Mason/Rost, Skaggs/
Broadhead, Irwin/Whiteley)
⢠Reduced peak flows in streams (Skaggs: 89%)
⢠Reduced soil erosion due to overland runoff -55% (Baker/
Johnson, Hill, Loudon, Belcher/Fogiel, Skaggs)
⢠Reduced movement of P (48%), K (22%), and pesticides
(50%) (Gaynor/Loudon, Muir, Bastien)
50. Tile Drainage - Environmental Benefits
⢠Green Benefits
â Decreased fossil fuel consumption (Madramootoo,
Wind)
â Decreased greenhouse gas production
⢠Less CO2 from fossil fuel burn
⢠Less denitrification
51. Ontario: 100+ year history of tile drainage
⢠No license or permits required by landowner to tile
⢠Contractor, machine, and operator require training and
license
⢠Tile activities to be reported at year end
Regulations
52. Manitoba:
⢠Drainage License required by Manitoba Water
Stewardship (application, $25 fee)
⢠Permission required from recipient (i.e. outlet into RM
ditch or neighbour)
⢠Consistently inconsistent
⢠Currently in limbo - massive new changes being proposed
(Surface Water Management Strategy)
Regulations
53. Saskatchewan:
⢠Approval to Construct and Operate Drainage Works
⢠Aquatic Habitat Protection Permit
Regulations
