Plumbing (from the Latin plumbum for lead as pipes were once made from lead) is the skilled trade of working with pipes, tubing and plumbing fixtures for drinking water systems and the drainage of waste. A plumber is someone who installs or repairs piping systems, plumbing fixtures and equipment such as water heaters. The plumbing industry is a basic and substantial part of every developed economy due to the need for clean water, and proper collection and transport of wastes.

Plumbing also refers to a system of pipes and fixtures installed in a building for the distribution of potable water and the removal of waterborne wastes. Plumbing is usually distinguished from water and sewage systems, in that a plumbing system serves one building, while water and sewage systems serve a group of buildings or a city.

The City of Vancouver was incorporated on 6 April 1886, the same year that the first transcontinental train arrived. CPR president William Van Horne arrived in Port Moody to establish the CPR terminus recommended by Henry John Cambie, and gave the city its name in honour of George Vancouver. The Great Vancouver Fire on 13 June 1886, razed the entire city. The Vancouver Fire Department was established that year and the city quickly rebuilt. Vancouver's population grew from a settlement of 1,000 people in 1881 to over 20,000 by the turn of the century and 100,000 by 1911.
