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 https://www.wateronline.com/doc/leopold-type-xa-underdrain-0001 http://www.westech-inc.com/en-usa/products/filter-underdrain-multiblock

Bioretention soil is engineered soil with the right mix of sand, soil and compost (low nutrient - not manure, more leaf) depending on project location. 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/

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)

Deeper water is cooler, sediment further, algae and plant growth inhibited. Ideally at least 5 feet 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 preventcontamination 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 https://www.quora.com/How-does-a-centrifugal-pump-work https://www.rcworst.com/Barmesa-IA4BJH-60-4-TEFC-End-Suction-Centrifugal-Pump

13. 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

14. 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

15. 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.

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/ 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)

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 https://www.wayfair.ca/Moen--Inly-Aromatherapy-Multi-Function-Handheld-Shower-H ead

18. 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

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)

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

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

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

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.
