           6. Any variation to the approved drawings will require a further referral to Unitywater for
              consideration prior to commencing the building work. Such amended proposals will be considered
              on their individual merits and may or may not be considered favourably.

           7. To ensure the design clearance is attained; the line of the infrastructure, including the sewer
              sewerage property connection point, must be accurately located on the property prior to
              commencing the building work. In the event the actual clearance is less than design clearance, a
              further referral to Unitywater is required and the resultant response shall be acted upon
              accordingly.

           8. A CCTV Survey of the sewer main as shown on the enclosed GIS Map is to be performed by an
              independent contractor and submitted within twenty (20) business days from the footing system
              for the building work having been completed.

                 NOTE: To submit the relevant CCTV video file/s and report documentation to Unitywater, send
                 an email request to [email protected] to arrange an Objective Connect link

                     the GIS Map and is to be submitted to Unitywater for assessment within ten (10) business

                     location and characteristics of reportable features (i.e. sewer main defects) and other
                     essential details necessary to define the extent of the survey (i.e. the length of the main,
                     chainages of defects, sewer property connections, etc). An example of an acceptable
                     Technical Report is enclosed for your reference.
