Coordination of drainage renewal with reconstruction of above-ground infrastructure is essential to minimize disruption in neighbourhoods. This program includes mainline sewer replacement with open-cut or relining methods, manhole repairs and renewal of service connections in neighbourhoods built before 1989.
Drainage Services spent about $28 million rehabilitating 53 km of sewers in developed neighbourhoods in 2010. The following is a list of neighbourhoods where sewer renewal works have been carried out recently:
| Alberta Avenue | Capilano | King Edward Park |
Terrace Heights |
| Aldergrove | Crestwood | Laurier Heights |
Thorncliffe |
| Argyll | Dovercourt | Lendrum Place |
Weir Industrial |
| Athlone | Duggan | Montrose |
West Jasper Place |
| Belgravia | Empire Park | North Glenora |
Westridge |
| Belvedere | Glenora | Ritchie |
Westwood |
| Bonnie Doon | Greenview | Sherwood |
Windsor Park |
| Canora | Grovenor | Summerlea |

This program plans renewal in 20 neighbourhoods over the next three years at a cost of about $147 million from the drainage utility
