FlowPlan Projects

A project-led view of how FlowPlan work turns into a delivery-ready route, from early decisions to vendor-ready scope, clear package boundaries, and commissioning checks.

Select a pathway to see what triggers it, what inputs we need, and what you get, so scope, package boundaries, and verification requirements are defined before vendor conversations begin.

OVERVIEW

Each pathway gives the project a clearer basis for procurement, delivery, and verification.

Pathways are organised around recurring project situations, so route, package boundaries, and verification requirements can be defined early enough for procurement, delivery, and verification to stay aligned.

Pathways are grouped around common project situations, STP, ETP, reuse, biosolids, equipment, and brine management, so route, inputs, and expected deliverables can be compared early.

That gives the project a clearer basis for procurement, delivery, and verification, while keeping package boundaries and performance requirements visible from the outset.

Common project situations addressed in this section

  • “We need a practical pathway, not a generic concept.”
  • “We need options compared properly before procurement.”
  • “We must define performance criteria and KPIs so delivery does not drift.”
  • “We need owner-side coordination across vendors and handover points.”

COMMON SITUATIONS

Recurring project conditions that need to be brought under control early.

These are the situations the pathways are designed to get ahead of, so scope, package boundaries, and performance criteria are defined early enough to influence outcomes rather than explain problems after the fact.

Procurement is moving but the scope isn't clear enough yet

Vendors are quoting from different assumptions. You need a basis document that defines flows, loads, package boundaries, and performance criteria before the RFP goes out.

The scheme direction is agreed but hasn't been engineered

You know what you're building but not what the sizing basis is, where the package boundaries lie, or what commissioning needs to verify. That gap needs to close before packages are let.

A system is underperforming and the cause isn't obvious

Treatment isn't hitting targets, or a commissioned system isn't stable. The problem usually lies at a handover point - between process units, between vendors, or between design and operation.

We support projects from early decisions to vendor-ready delivery, with scope, package boundaries, and performance criteria clearly defined.

This section shows how that support is structured across scoping, procurement, and implementation, so project requirements are defined early and carried through delivery with less ambiguity.

  • Problem definition, site constraints, and pathway selection
  • Feasibility, economics and risk assessment (board / lender-ready)
  • Inputs checklist and early KPI targets for vendor conversations
  • ToR / specification structure and package boundary notes
  • Bid comparables and verification requirements (guarantees)
  • Risk reduction through scope boundaries and performance ranges
  • Integration readiness: connections, shutdown periods, controls
  • Commissioning checks aligned to the completion plan
  • Post-implementation review: outcomes vs KPIs

FlowPlan Project Pathways

Select a pathway below - triggers, required inputs, deliverables, and linked sections update in the panel.

Pathway

FlowPlan - STP+ (modular municipal treatment)

A structured pathway for new builds or upgrades where biological stability, operability, and performance verification need to be clear before vendor engagement.

Vendor-aligned Implementation-ready Connections first

Typical triggers

  • New STP or retrofit where performance uplift is needed
  • Space constraints and phased upgrades
  • Reuse intent emerging (TSE/irrigation/cooling makeup)
  • Need clarity on package boundaries between biology, separation and disinfection

Key deliverables

  • Project Background / Feasibility assessment
  • Design basis & package boundary notes (vendor-ready)
  • Bid comparison structure and verification requirements
  • Commissioning completion checklist

Inputs needed

  • Influent + target effluent/reuse intent
  • Flow profile (avg/peak), footprint constraints
  • Existing tank volumes and aeration capability
  • Sludge route and operational constraints

Engagement Patterns

Four common ways projects are packaged, from early scoping through commissioning and upgrade planning.

Scoping

Feasibility assessment → pathway selection → inputs checklist

When the project intent is clear but the route is not, we set out the main risks, narrow the viable options, and build the inputs checklist for vendor conversations.

View project pathways

Procurement

Option set → vendor comparables → completion plan

Used when multiple vendors exist with overlapping scopes. We define package boundaries, verification points, and bid evaluation criteria so quotes are genuinely comparable.

View advisory route

Commissioning

Integration readiness → completion checks → handover

As installation approaches, the focus turns to readiness. We confirm connections, shutdown periods, and commissioning checks so the completion plan carries through properly.

Upgrade planning

Performance gap → retrofit options → phased roadmap

Where a plant is underperforming or permit limits are tightening, we define the gap, identify retrofit options, and sequence the improvements without rework.
