During heavy rain events, more water can enter the sewers under the street than they can handle due to the extra water being added from the weeping tiles. This excess water could potentially come back into the home if the sewer becomes overwhelmed. As a result, municipalities throughout Ontario including London and Stratford have instituted programs and subsidies for homeowners where drain tile is hooked up to municipal drains.

If it has not already been done, disconnect all downspouts from the weeping tile. Direct roof water away from the house using downspouts that empty into lateral piping that deposits water on a sloping grade a minimum of 5 ft. away from the foundation.
Disconnect weeping tile from sanitary or storm sewer lateral line to street
Install Backflow Preventer on sanitary line
Seal existing storm sewer lateral line
