Every region has its own rules, risks, and climate – but when it comes to water, the questions growers face are surprisingly similar.

  • How much water do I have?
  • How much can I use – and when?
  • What happens if the season turns dry?

Whether you’re navigating SGMA in California, managing carryover and allocations in Australia, or working within changing consent rules in New Zealand, one thing is consistent: water planning is no longer optional. But that doesn’t mean it needs to be difficult.

At SWAN Systems, we built the Water Supply Manager to help make sense of a complex, fragmented reality. We didn’t start with policy documents or compliance checklists. We started with conversations – with growers, councils, and portfolio managers who were frustrated by how hard it was to get a straight answer to a simple question: How much water do I actually have?

Too often, the answer was buried in disconnected spreadsheets, hard-to-read statements, or gut feel. Add to that the uncertainty of allocations, trade approvals, or shifting rules – and even experienced irrigators were spending too much time chasing information instead of making decisions.

Water is your most valuable input. Managing it shouldn’t be guesswork.

Our goal wasn’t to create a system for bureaucrats. It was to build a planning tool for people on the ground – a system that shows, in one place:

  • What’s in storage (across multiple accounts if needed)
  • What’s been used and when
  • What’s still available for the season
  • And whether your current plan still stacks up

That clarity unlocks more than compliance. It unlocks confidence – in your budgets, your crop plans, and your ability to pivot when conditions change.

In California, the Water Supply Manager has the potential to simplify SGMA reporting and support clearer water budget conversations.
In Australia, it’s already proving useful for managing carryover, metered extraction, and entitlement juggling across complex portfolios.
And in New Zealand, it’s well placed to support consent management, improve transparency, and feed into seasonal water demand forecasting.

This isn’t about automating decisions. It’s about empowering them – giving irrigators, water managers, and landowners the visibility they need to plan, respond, and defend their choices when needed.

We can’t make the rain fall. But we can make it easier to manage what you’ve got – and help turn complexity into clarity, one decision at a time.
