This list contains water meters operated by the City of Montreal Water Department. The meter pool is used to carry out water balances and makes it possible to measure the water distributed to the other municipalities forming the agglomeration of Montreal. This list is a view of the situation at the time the file was generated. NOTE: The data in this set aims to have a better understanding of the number of industrial, commercial and institutional water meters installed as part of the City of Montreal's water consumption measurement strategy. For reasons of challenges in the protection of third party industrial secrets, the consumption associated with these meters will not be published.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The main objective of this sampling program was to assess the effects of the spill on the toxicity of surface water collected during the spill by comparing them with the results of water collected prior to the discharge.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This data set represents the interventions determined by the City of Montreal's Intervention Plan for the period 2016-2021. This planning includes both the infrastructure deficit and the maintenance needs during the period in question. The Intervention Plan is the result of a macroscopic analysis of physical and state data. Moreover, the capacity of the City and its boroughs to carry out is not unlimited; it is often determined by a combination of factors, including the availability of budgets, coordination needs, planning capacity as well as the capacity of the market to carry out this work. Consideration should also be given to the social and economic impacts of infrastructure work. These are all factors that may justify the delay of several interventions to later years. The data are available in the following documents: - The summary table shows the classes of integrated interventions of A, B, C or D for the unified sections. For each section, a recommendation on the work is indicated if necessary. These tables help managers identify priority segments and sections. If the dates of work of the assets in the same street section are different, the section is repeated as many times as there are different dates for the section. - The digital file presents the results of the Intervention Plan per unified section. This unit is the linear geometric element that supports the management data for all the infrastructure segments of the intervention plan. The division of the unified section is usually done at roadway intersections and easement limits. If the dates of work of the assets in the same street section are different, the section is repeated as many times as there are different dates for the section. - The integrated interventions map shows the opportunities for coordinating interventions between the three drinking water, sewage and road networks.

The 2023-2027 results are available on the page [Results of the Action Plan for the assets of drinking water, sewage and roads networks (2023-2027)] page (https://donnees.montreal.ca/dataset/resultats-plan-intervention-actifs-eau-voirie-2023).**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The sewer system (secondary and main networks) on the Island of Montreal includes 170 overflow structures. An overflow structure consists of an underground control chamber that directs wastewater into the collection and interception network under normal operating conditions to the treatment plant. During rain, melt or during an operation associated with maintenance or impairment, the inputs exceed the regulatory capacity and this excess is overflowed by the structure in question in the watercourses. It is under these conditions that part of the water combining rainwater and wastewater flows to the receiving watercourse for a short period of time (via the outfall). Obviously, the receiving watercourse to the south is the St. Lawrence River and that to the north, the Rivière des Prairies.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This data set represents the interventions determined by the City of Montreal's Intervention Plan for the period 2023-2027. This planning, according to a division into unified sections (TU), includes both the infrastructure deficit and the maintenance needs during the period in question. The Intervention Plan is the result of a macroscopic analysis of physical and state data. Moreover, the capacity of the City and its boroughs to carry out is not unlimited; it is often determined by a combination of factors, including the availability of budgets, coordination needs, planning capacity as well as the capacity of the market to carry out this work. Consideration should also be given to the social and economic impacts of infrastructure work. These are all factors that may justify the delay of several interventions to later years. The data are available in the following documents: - The summary table shows the integrated intervention classes for the unified sections. For each section, a recommendation on the work is indicated if necessary. These tables help the managers of these infrastructures to identify priority segments and sections. - The digital file presents the results of the Intervention Plan by unified section in shapefile and geojson. It integrates the linear geometric elements that support the management data of all the assets analyzed in the intervention plan. The division of the unified section is usually done at roadway intersections and at easement limits. - The map of integrated interventions presents opportunities for coordinating interventions between the three drinking water, sewage and road networks. - The data dictionary detailing the metadata of geospatial digital files For more information on water management in Montreal, consult [the City of Montreal's website] (https://montreal.ca/unites/service-de-leau).**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This set of punctual data shows fire hydrants on the island of Montreal. These bollards are high devices located along streets, equipped with a water outlet supplied from the water pipes, to which the fire-fighting hoses are connected in order to ensure fire protection. The information associated with the geographic data corresponds to the date of installation, status, owner and jurisdiction. __CAUTION__: This data is published annually, so it does not include updates made during the year. For this reason, they should under no circumstances be used for engineering purposes without validation by the City.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

This set of punctual data shows the manholes located on the Island of Montreal. These manholes are compartments through which sewers can be accessed in order to clean, inspect and maintain them. The manholes are placed at regular intervals on the right-hand section of the main pipe. In straight sections, the maximum distance between two manholes is 120 meters. The manholes are generally placed at the beginning of a network, i.e. at the head of the furthest section and at the points where the pipe changes direction, altitude, slope and/or diameter. The information associated with the geographic data corresponds to the type and material of the manhole, date of installation, status, owner and jurisdiction. __CAUTION__: This data is published annually, so it does not include updates made during the year. For this reason, they should under no circumstances be used for engineering purposes without validation by the City.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
