A drainage diagram shows the location of the house’s internal and external service lines and the location of the Council’s sewer mains. A drainage diagram is a document that is required to be attached to a contract of sale as stated in the Conveyancing (Sale of Land) Regulation 2017.
Hawkesbury City Council is the sewer authority for a large portion of the local government area and reticulated sewer is provided by Hawkesbury City Council to the following areas:
- Bligh Park
- McGraths Hill
- South Windsor
and the majority of:
- Windsor Downs
- Pitt Town
Where reticulated sewer exists, a drainage diagram may assist in locating the sewer main, sewer junction and the private house service connection. For properties that are not connected to Council’s sewer, a letter will be issued stating that the land is not serviced by Council’s sewer.
If you are unsure whether the land is serviced by Council’s sewer, Sydney Water or is unserviced please contact Council’s Customer Service Centre on (02) 4560 4444 for more information.
