What is WULA hydrology support?

Water use licence applications often require defensible hydrology and clear impact motivation. We prepare technical annexes that connect modelling, monitoring, and operational controls.

Technical annexes that read as a coherent case

WULA submissions fail when hydrology is a disconnected appendix. We tie abstractions, return flows, and storm responses to the same catchment narrative used elsewhere in the application, with explicit monitoring hooks where DWS expects ongoing evidence.

Defensible under scrutiny

We flag where data is thin and how conservative assumptions protect the client without over-claiming certainty—so reviewers see judgement, not marketing.

What we typically need from you

  • Water use categories, volumes, and operational schedules proposed for the licence
  • Catchment context, existing lawful water uses, and any hydrological study precedents
  • Monitoring locations, baseline data, or specialist studies already commissioned
  • DWS pre-application guidance, scoping letters, or environmental record references

Where we add technical depth

  • Hydrology annexes that connect modelling, field evidence, and operational controls
  • Clear impact motivation where abstraction, impoundment, or discharge changes the regime
  • Tables and figures formatted for DWS technical reviewers and legal record
  • Integration with stormwater, groundwater, or mine water studies on the same site

When do you need this?

  • New or amended water uses under the National Water Act
  • Surface water impoundment, diversion, or discharge scenarios
  • Motivation requiring defensible hydrology and monitoring proposals

Our approach

  1. 1

    Use characterisation

    Map Section 21 categories, volumes, and operational controls.

  2. 2

    Hydrology & impact framing

    Provide design flows, scenarios, and impact reasoning aligned to DWS expectations.

  3. 3

    Mitigation & monitoring

    Define measurable controls and reporting hooks.

  4. 4

    Annex assembly

    Prepare technical annexes that integrate with legal and environmental workstreams.

What you'll receive

  • Hydrology annexes
  • Figures and tables for the application
  • Monitoring recommendations

Relevant SA standards

  • National Water Act & DWS guidance
  • NEMA where environmental processes run in parallel

FAQ

Do you compile the full WULA?

We focus on hydrology/technical annexes; legal and EAP coordination sits with your team.

Can you support amendments?

Yes—scoped to changed hydrology/operations and revised monitoring.

What data do you need?

Operational schedules, catchment context, and prior water-related studies.

Reserve considerations?

Where relevant, we support technical discussion of resource protection outcomes alongside legal advisors.

Monitoring design?

We propose measurable indicators and reporting frequencies aligned to operational controls.
