The soil has to provide good water infiltration, have a large capacity to sequester pollutants and support vegetation and healthy microorganisms. www.dirtconnections.com/what-is-bioretention-soil/ https://www.ecolandscaping.org/03/managing-water-in-the-landscape/storm water-management/bioretention-soils/ Page 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) Deeper water is cooler, sediment further, algae and plant growth inhibited. Ideally at least 5 feet deep. Page 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 preventcontamination of groundwater Page 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 https://www.quora.com/How-does-a-centrifugal-pump-work https://www.rcworst.com/Barmesa-IA4BJH-60-4-TEFC-End-Suction-Centrifugal-Pump -60-HP-3PH-p13029.html Page 14 https://unitedstates.xylemappliedwater.com/brands/vertical-turbine/ vertical-turbine-smvt-canned/ hhttps://unitedstates.xylemappliedwater.com/brands/vertical-turbine/vertical-turbine-smvt-canned/ Page 15 Surface Water For non- flowing water also need to consider aeration For flowing water also need to considerFluctuation in water level - use float on intake Flooding https://www.amazon.ca/Kasco-Marine-2400VFX100-5HP-Aerating/dp/B004FJF7NC/r ef=asc_df_B004FJF7NC/?tag=googleshopc0c-20&linkCode=df0&hvadid=293001317 889&hvpos=&hvnetw=g&hvrand=12303290996638135131&hvpone=&hvptwo=&hvqm t=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9001350&hvtargid=pla-492175908939 &psc=1 https://globalnews.ca/news/7014532/calgary-bow-elbow-rivers-high-water-advisory/ Page 16 Rainwater Harvesting Successful in temperate zones with consistent rainfall or used as supplemental in more arid climatesWatch water quality - -roof tops usually goodHard surfaces (parking lots) sometimes not good https://www.environmental-expert.com/products/keyword-commercial-rainwater-86398 https://www.environmental-expert.com/products/keyword-commercial-rainwater-86398 Page 17 Treated Reclaimed water ( Stormwater) -treated to the extent that it poses no significant health or environmental hazardsStill 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 lavenderGray water can be used immediately in households for subsurface drip only. Page 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/ https://www.espwaterproducts.com/understanding-ro/ Includes 4 stages of water purification 1. Sediment filter, 2. Carbon filter 3. RO membrane 4. Finishing filter (carbon) Page 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 https://www.wayfair.ca/Moen--Inly-Aromatherapy-Multi-Function-Handheld-Shower-H ead Page 20 Other alternatives Eliminate Irrigation WasteManage Irrigation ScheduleUse smart controllers that automatically adjust water based on daily ET rates, Kc or soil moisture. Manage Water Source Availability Harvesting and storage Page 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) Well construction falls under the water act as well as any water that is diverted (used) from a stream, creek, etc. All areas responsible for erosion control and construction around water Page 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 Any spills that affect water, broken pipe in municipal systems etc all after to go through Alberta Environment There Is also a federal environmental protection agency Page 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.
