Bulk Water Stations

The City of London has several automated bulk water stations spread geographically throughout the city to allow bulk water haulers to obtain potable water from the distribution system year round, 24 hours per day, 7 days a week (view map).  These bulk water stations have been designed to eliminate the need for withdrawal of water from fire hydrants. The practice of allowing fire hydrant connections is heavily limited due to the impacts they have on the water distribution system. Bulk water stations are specifically designed to minimize the potential for contamination of the water supply and reduce discoloured water events. Unauthorized withdrawal of water through a fire hydrant is considered illegal. 

Bulk water stations dispense a high volume of water over a short amount of time. They are intended to be used for supply of large quantities of water (in excess of 1,000 litres). Attempting to fill tanks smaller than this will result in overflow and possible damage to the user’s equipment.  

The City of London’s bulk water stations are accessed using prepaid smart cards. These cards allow bulk water haulers to obtain water and subsequently the card balance is updated based on water dispensed.  Smart cards can be used at any bulk fill station.  The initial set up and balance top-ups of the smart card must be done at:

City Hall
7th Floor, Special Events and Approvals
Monday to Friday, 8:30 a.m. to 4:30 p.m. (excluding statutory or declared holidays)
Accepted Methods of Payment include: Cash, Cheque, or Debit.

There are risks and difficulties associated with taking water from a fire hydrant. All fire hydrant connection requests are reviewed on a case by case basis. Typically, they are only allowed in situations where a very large volume of water (200,000 litres and up) is required over a short amount of time. Costs associated with fire hydrant connections can be found in Water By-law W8. Unauthorized connections or water taking from a fire hydrant is considered illegal. If you wish to inquire about the possibility of obtaining a fire hydrant connect please send an email at least 7 days in advance, and include: volume and flow you require, when the connection will be required, length of time the connection will be needed, location, purpose of work, and your contact information.

Please note that due to the age and material of some water infrastructure, certain areas of the City cannot be provided with a bulk water fire hydrant connection under any circumstance.
