Scoping
Need → options → project definition
When the need is clear but the route is not, we identify the main risks, compare viable options and set out the information needed for the next stage.

FlowPlan Projects
FlowPlan Projects brings the main treatment process, supporting systems and project requirements together, so important questions are resolved before they lead to design changes, procurement gaps or commissioning problems.
Explore pathways for sewage treatment plants (STP+), effluent treatment plants (ETP), treated water reuse, biosolids, equipment, ZLD and multi-package procurement.

OVERVIEW
Start with the project situation you are trying to resolve.
Each pathway starts with a situation owners and project teams commonly face. It then shows what should be checked, the information needed and the technical work required before the next decision.
The pathways cover sewage treatment plants (STP+), effluent treatment plants (ETP), treated water reuse, biosolids, equipment, ZLD and multi-package procurement. Each keeps the main duty in view while bringing in the supporting systems and decisions that can affect performance, cost or delivery.
This makes it easier to compare options, brief suppliers and carry the selected decisions into design review and commissioning.
What is considered alongside the main package
- Upstream conditions that affect the treatment duty
- Reuse, residuals, utilities and controls linked to the main package
- Supplier responsibilities and connections between packages
- Checks needed before acceptance and operation
COMMON SITUATIONS
Three situations where early clarification can prevent later problems.
These situations are different, but each benefits from clarification before more money, design time or site work is committed.
Procurement is moving but the scope is not clear enough
Vendors are pricing against different assumptions. The immediate need is a common design basis, clear package responsibilities and performance criteria that can be used to compare offers before award.
The preferred route is known but the engineering work is incomplete
The intended process or package is understood, but flows, loads, sizing assumptions, connections and commissioning checks have not been worked through far enough for procurement or detailed design.
A system is underperforming and the cause is not clear
The cause may lie in influent conditions, process duty, equipment, controls, operation or handovers between packages. The pathway helps identify what must be checked before an upgrade is selected.
Support can begin at different project stages.
The work is scaled to the immediate decision. It can start with feasibility, move into supplier alignment, or focus on implementation and performance checks.
- Define the project need, site constraints and viable routes
- Compare options, economics and key risks
- Set the information and performance criteria needed for the next stage
- Structure the scope, specifications and package responsibilities
- Normalise supplier assumptions and compare offers on the same basis
- Set the performance criteria and acceptance checks to carry into procurement
- Confirm connections, controls, shutdown requirements and responsibilities
- Align commissioning checks with the agreed design and procurement criteria
- Review early performance against agreed criteria and identify follow-up actions

Pathway
FlowPlan - STP+ | Sewage treatment plants
For new sewage treatment plants, upgrades or performance recovery where the treatment duty, supporting systems and acceptance checks need to be worked through together.
Main package
Supporting systems
Delivery checks
Typical triggers
- New sewage treatment plant or capacity upgrade
- Plant underperformance or unstable operation
- Reuse, sludge or odor needs affecting the treatment route
- Multiple packages or vendors with unclear responsibilities
Technical outputs
- Confirmed design basis and treatment route
- Sizing and performance criteria for key process units
- Package responsibilities, connections and supplier comparison criteria
- Commissioning and acceptance checks
Inputs needed
- Influent flows, loads and variability
- Required discharge or reuse quality
- Existing plant data, layout and operating constraints
- Sludge, utilities, controls and site limitations
Typical project entry points
Support can begin where the project needs attention. It does not have to follow a fixed sequence.
Procurement
Scope → comparable offers → award recommendation
When suppliers are already involved, we align assumptions, responsibilities and acceptance criteria so offers can be reviewed consistently.
View sourcing supportCommissioning
Readiness → testing → handover
As installation approaches, we check connections, controls, responsibilities and the test plan against the agreed design and acceptance criteria.
View engagement roadmapUpgrade planning
Performance gap → upgrade options → phased plan
For an underperforming plant or tightening requirement, we define the gap, compare upgrade options and set a practical sequence for implementation.
View treatment projectsDiscuss the project
Share the project type, current stage and the decision that needs attention. A short description is enough to help us identify the most useful starting point.
Useful details to include
- Project location and the treatment, reuse, residuals or equipment need.
- Where the project stands and what needs to be decided next.
- The main technical, procurement or commissioning concern.
