Applying to self-lay
Developers can choose to use a self-lay organisation (SLO) to install or ‘self-lay’ new water mains and/or service connections.
We have codified strict service level policies to ensure that a developer’s chosen SLO works to the standards we require so that that neither the developer nor the public at large suffer financial loss and disruption to the quality of supply respectively. It is important that the developer only engages a WIRS accredited SLO and either they or their chosen SLO submits the necessary application forms for all self lay applications.
Self-lay provides three choices:
- Mains and services: The developer uses an SLO for all the work
- Mains only: An SLO installs mains and we or another SLO makes service connections
- Services only: An SLO makes service connections to a main installed by us or another SLO
Don’t forget that you can now register to access our online network asset portal to search and print maps of our underground water network: convenient, practical and mobile.
