| #Q003 | administrative | unknown | mandatory | Community Water Licence Requirement | drinking water | The federal government requires all communities have a water licence. | The only exceptions are Dettah, the Hay River Reserve and Kakisa. They are either too small to need a water licence, or they use facilities in other communities to get their drinking water and dispose of their waste. | high |
| #Q004 | monitoring | operational | mandatory | Raw Water Quality Testing Requirements | drinking water | They now require daily turbidity testing, monthly bacteria testing and annual chemical testing for raw water. | Communities that get their water from other communities do not need to take raw water bacteria samples.

Dettah and Hay River Reserve get water from other communities but add chlorine to it - they do not need to take treated water chemical samples but do need to take treated water bacteria and THM samples. | high |
| #Q008 | treatment | health | mandatory | General Water Quality Standard Compliance | drinking water | In the NWT, we use the treated water quality standards set in the NWT Public Water Supply Regulations and the Guidelines for Canadian Drinking Water Quality (GCDWQ). | high | |

| #Q011 | administrative | operational | mandatory | Water Licence Inspection Frequency | drinking water | INAC Officers do yearly water licence inspections. | high | |
| #Q012 | operational | operational | guideline | Operator Redundancy Goal | drinking water | The goal is to increase the total number of certified operators working in the NWT and to make sure every community has a primary and back-up operator certified to the level of their local WTP. | high | |
| #Q013 | administrative | reporting | mandatory | Water Quality Database Maintenance | drinking water | HSS keeps the website up to date, adding new data as it becomes available. | high |

| #D011 | Small Systems | Most small systems in the NWT add chlorine to unfiltered surface water. Some small systems also use a cartridge or membrane (micro or nano) filter. | medium | |
| #D012 | Class 1 | Most Class 1 WTPs in the NWT use filtration and chlorination. The typical NWT Class 1 plant gets its raw water from a groundwater well. | medium | |
| #D013 | Class 2 | The typical Class 2 water treatment system starts with screening out coarse particles in the water. Chemicals are added to the water to make the remaining small particles clump together into larger particles that settle out in the sedimentation tank. The water then flows through a filter to remove any particles that are left. Finally, chlorine is added to the water to disinfect it. | medium | |
