Who we are

Delivery-minded design, independent from solutions.

Aqua Design supports owners, operators and project teams to move from site conditions to a scope that can be priced, delivered, and verified.

We take a clear technical position on configuration, connections and review criteria, and help you select and manage solution providers against that outline.

Baseline that reflects variability

Not "average day" assumptions, but representative sampling, load variability, and actual operating limits.

Vendor engagement that is comparable

Same scope, same responsibilities, and the same performance ranges, so proposals can be genuinely compared.

Delivery checks defined upfront

Commissioning tests, QA/QC, and completion criteria agreed before delivery starts, not negotiated at the end.

Independent from solutions. Not neutral on outcomes.

Phases: Clarify, Configure, Deliver, to keep every project on track.

100%

Independent advice focused on site needs, delivery clarity, and day-to-day performance.

Our values

How we show up in
every engagement.

The principles guiding every recommendation, every scope, every handover.

◇

Clarity

We reduce complexity into decisions that teams can act on, with no ambiguous recommendations and no scope gaps.

◎

Accountability

We define criteria early and track them through delivery. What gets measured gets delivered.

⬡

Operability

We specify for running plants, not just drawing sets. Day-to-day performance over theoretical compliance.

↺

Sustainable

We design for resource recovery and long-term operability, not just meeting today's compliance threshold.

Our approach

Plan like a builder. Specify like an operator.
Verify like an owner.

Our commitment

Water and waste as resources, not problems

We treat water use, reuse, and residuals management as opportunities from the earliest stage, not as afterthoughts. Early direction leads to better decisions, not just compliant ones.

How we work with clients

Patience with complexity, clarity on the outcome

Water projects carry conflicting perspectives between owners, operators, regulators, and vendors. We bring the patience to work through that, and the discipline to keep refining until the outcome is deliverable.

Collaboration

The right expertise around each problem

Every engagement draws on the expertise the duty actually requires, working with clients, specialist collaborators and vendors to keep recommendations practical.

Our process

Introducing FlowPlan

Our structured way of moving from diagnostics to a vendor-ready scope, keeping constraints, configuration logic, and verification steps in one place. Explore FlowPlan →

Engagement flow

How engagements typically progress

Clarify

Define the problem, constraints, and success metrics, then confirm viability before any design work begins.

Typical outputsFeasibility snapshot, risk register, KPIs & review ranges, recommended next step.

Configure

Map a practical pathway for treatment, residuals, reuse, and connections, ready for vendor engagement.

Typical outputsFlowPlan configuration summary, block PFD, connection list, vendor scope / ToR outline.

Deliver

Translate into a vendor-ready scope with verification steps through installation and commissioning.

Typical outputsVendor-ready scope pack, scoring framework, commissioning test plan.

What keeps projects on track

Four decisions that determine
whether a system holds up

Not just on paper, but in day-to-day operation.

Start with today's site conditions

Representative sampling, load variability, and operating limits come before any design overview. Assumed averages fail at the edges, and water systems often operate there.

Structure the vendor engagement

We align scope, connections, and responsibilities so vendors quote on the same outline, proposals are genuinely comparable, and there are no gaps at handover.

Define delivery checks before start-up

Commissioning tests, QA/QC, and performance ranges agreed upfront, not negotiated at completion. That keeps delivery aligned to what was agreed.

Keep reuse and residuals viable

Outcome-first means verifying that reuse outlets, biosolids markets, and OPEX targets are achievable under actual operating conditions, not just in the design case.
