|
Urban use
|
| Unrestricted |
Landscape irrigation (parks, playgrounds, school yards), fire protection,
construction, ornamental fountains, recreational impoundments, in-building
uses (toilets, air conditioning) |
| Restricted-access irrigation |
Irrigation of areas where public access is infrequent and controlled (golf
courses, cemeteries, residential, greenbelts) |
|
Agricultural irrigation
|
| Food crops |
Crops grown for human consumption and consumed uncooked |
| Non-food crops, food crops consumed after processing |
Fodder, fibre, seed crops, pastures, commercial nurseries, sod farms,
commercial aquaculture |
|
Recreational use
|
| Unrestricted |
No limitations on body contact (lakes and ponds used for swimming,
snowmaking) |
| Restricted |
Fishing, boating, and other non-contact recreational activities |
|
Environmental use
|
Artificial wetlands, enhanced natural wetlands, and sustained stream
flows |
|
Groundwater recharge
|
Groundwater replenishment, saltwater intrusion control, and subsidence
control |
|
Industrial reuse
|
Cooling system makeup water, process waters, boiler feed water, construction
activities, and washdown waters |
|
Potable reuse
|
Blending with municipal water supply (surface water or groundwater) |
