Documentation requirements for new CWMS connections are determined through the Development Assessment (DA) process in accordance with South Australian planning legislation and the PlanSA framework.
Generally, applicants will be required to submit detailed, surveyed plans (in AHD) prepared by a licensed surveyor or plumber. These plans should show the location and depth of the existing CWMS network, proposed connection points, depth and length of pipework proposed, and all relevant development application details.
Additional supporting information may be requested where required to enable assessment. Commercial developments and larger land divisions typically require more detailed documentation. For CWMS‑specific advice, please contact cwms@alexandrina.sa.gov.au
