Water for Irrigation

Slide 1 Water for Irrigation LHAP 302 Slide 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/ Slide 3 Ground Water Pg 8 Sometimes classified as potable water Slide 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 Slide 5 Slide 6 Slide 7 Some groundwater is so clean it can be considered as potable water. Water test through Alberta Health Services Sample your water Slide 8 https://www.homedepot.com/p/Everbilt-1-HP-Submersible-2-Wire-Motor-10-GPM-Deep-Well-Potable-Water-Pump-EFSUB10-122HD/205618068 Slide 9 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 Slide 10 http://prj.geosyntec.com/npsmanual/bioretentionareasandraingardens.aspx Slide 11 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) Slide 12 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 Slide 13 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 Slide 14 hhttps://unitedstates.xylemappliedwater.com/brands/vertical-turbine/vertical-turbine-smvt-canned/ Slide 15 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 Slide 16 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 Slide 17 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. Slide 18 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/ Slide 19 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 Slide 20 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 Slide 21 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) Slide 22 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 Slide 23 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.
