A water service pipe, also known as a water service line, is the way drinking water is delivered to each home in Calgary. The water service pipe can be thought of as two sections:
(1) From the water main to the property line: This part of the pipe is owned and maintained by The City of Calgary.
(2) From the property line to your house: This part of the pipe is owned and maintained by the homeowner.
The data shown here only relates to the portion of the water service pipe on public property, owned and operated by The City. The material on private property can be a different material, and could have been installed at a different time. The data shown on this map is subject to change due to parcel re-development or The City repair/maintenance activities. If you believe there is an error or an omission regarding to the pipe material provided on this map, please contact 311.

This dataset makes historical air quality data accessible for various parameters at Calgary monitoring stations. The data is collected by the Calgary Region Airshed Zone and submitted to Alberta Environment and Parks (AEP). The data is delivered to the airdata warehouse, a central repository for Alberta's ambient air quality data via a web service provided by AEP. In this way, AEP provides access to quality controlled historical air quality data at its air quality stations.
In addition to air quality monitoring data, an Air Quality Health Index (AQHI) is calculated hourly at certain monitoring stations. The AQHI is a simple way to interpret air quality conditions: it provides a number from 1 to 10+ which indicates the relative health risk associated with local air quality. The higher the number, the greater the health risk. Further information on the AQHI calculation is available at: https://www.alberta.ca/air-quality-health-index--calculation.aspx

Under the Food Regulation, restaurant inspections occur prior to the opening of a new facility, every four to six months thereafter or more often if non-compliance with the regulation has been identified.
