The LASA water main replacement work on Northgate, Midway and Greenook Boulevard has begun, and the following information in detail was received from the Sanitary Authority yesterday. We apologize for the short notice that you are receiving from LASA.

The new water main is being installed by a trenchless technology called horizontal directional drilling where lengths of pipe are installed without open cutting the entire way. Connections and services leads are excavated as necessary. The process will take several weeks for:
- Installation of new water main, hydrants, and valves 
- Testing and disinfection of the new water main
- Individual services disconnected from the existing main and tied into the new main. Each house will be without water service for a couple of hours during the switchover. We will contact individual homeowners when their water service is being switched over.
- Restoration of disturbed areas as the weather allows.

Where possible, the connection between the new main and existing system is done without turning off service. Where an existing valve requires replacement, service interruption may be necessary. Any potential service interruption will be communicated via email and/or door hangers.
