A backup sewage pump, or backup sewage line, could be a major upgrade for a number of NHL teams.
The Buffalo Sabres, Detroit Red Wings, Anaheim Ducks, Los Angeles Kings and Edmonton Oilers are among the teams with backup systems in place.
The league currently has 12 teams that use backup systems.
However, the league has an option to increase the number of teams that can deploy backup systems to 15 if the NHLPA approves it.
The plan is to go with a system that uses a sewage treatment plant.
If that doesn’t happen, the NHL could consider adding backup sewage systems for teams that don’t have backup systems, according to the Associated Press.
If the plan goes through, backup sewage lines would allow a team to have an uninterrupted supply of drinking water in the event of an emergency, according the AP.
A backup system would also allow the teams to have backup sewage piping, which could be used to pump water back into the sewage treatment plants.
The AP also reported that the backup sewage pipes would have to be made of steel and could take some time to be constructed.
The NFL, NBA and NHL are the only sports leagues that have backup water systems in existence.
