1. Water for Irrigation

LHAP 302

2. Potable Water - Pg 8

Attach system directly to home water source Needs backflow prevention

Easiest, safest, reliable flow and pressure Most expensive (pay for treated water) https://markhamglobal.com/markham-videos/potable-water-certification/

3. Ground Water Pg 8

Sometimes classified as potable water

4. Collecting Groundwater Pg 11

Wells

Water quantity and quality may vary - get tested by a professional before you dig. Submersible pumps or vertical turbine pumps http://www.county.camrose.ab.ca/content/water-wells

Course visual for Collecting Groundwater Pg 11

5. Some groundwater is so clean it can be considered as potable water

Some groundwater is so clean it can be considered as potable water.

Water test through Alberta Health Services Sample your water

7. Ground Water

Underdrain ( weeping tile that leads to a cistern)

Rain gardens or infiltrated pond water with perforated pipe and collection pump at a sufficient depth below the pond https://www.wateronline.com/doc/leopold-type-xa-underdrain-0001

9. Surface Water

Rivers, Streams Provide natural aeration through water movement

Water levels can fluctuate significantly Regulated heavily - important resource

Water quality depend on depth and size (ideally at least 5 ft deep)

10. Surface Water

Man-made - lagoons, stormwater retention ponds Provide upstream and downstream filtration (200 mesh minimum) Provide aeration Seal ponds with rubber liners or bentonite etc. to prevent contamination of groundwater

11. Surface Water

Use centrifugal or vertical turbine pumps (submersibles often don’t generate enough pressure or flow)

For all sources of surface water you’ll need to Consider extra filtration

13. Surface Water

For non-flowing water also need to consider aeration

For flowing water also need to consider Fluctuation in water level - use float on intake Flooding

14. Rainwater Harvesting

Successful in temperate zones with consistent rainfall or used as supplemental in more arid climates

Watch water quality - -roof tops usually goodHard surfaces (parking lots) sometimes not good https://www.environmental-expert.com/products/keyword-commercial-rainwater-86398

15. Treated Reclaimed water ( Stormwater)

treated to the extent that it poses no significant health or environmental hazards

Still viewed as a potential health hazard due to chemical and biological contaminants

Piping and equipment used has signage (NONPOTABLE) and uses the colour purple or lavender

Gray water can be used immediately in households for subsurface drip only.

16. Reverse Osmosis

Mechanical method of purifying water through a semipermeable membrane

Very expensive

May strip nearly everything in the water. https://www.espwaterproducts.com/understanding-ro/

17. Gray Water

Gray water can be used immediately in households for subsurface drip only.

Gray water cannot be stored for more than 24-hours.

Household water that comes from sources other than toilets or kitchen sink

18. Other alternatives

Eliminate Irrigation Waste Manage Irrigation Schedule

Use smart controllers that automatically adjust water based on daily ET rates, Kc or soil moisture.

Manage Water Source Availability Harvesting and storage

19. Water Regulations - Provincial

ALBERTA WATER ACT - support and promote the conservation and management of water, including the wise allocation and use of water…..

Water diversions are managed primarily through a system of water licenses issued by Alberta Environment under the WATER ACT

And once more!! (Review of first and second year)

20. Water Regulations - Provincial cont.

EPEA - protection enhancement and wise use of the environment ( wastewater effluent to pesticide sales)

Interprovincial agreement “One-half of the natural, eastward flow of waters rising in, or flowing through, Alberta is reserved for Saskatchewan;” 1969

21. Water Regulations - municipal

Municipalities are primarily responsible for drinking water distribution, wastewater collection, and wastewater treatment as well as stormwater management.

Municipalities can develop bylaws to help regulate water use and water shortage response plans.

Examples are the use of water meters, types of backflow prevention, and water windows for irrigation.
