Treated Water Reuse Projects

Reuse intent set but the pathway isn't scoped? Polishing vendor selected before end-use was confirmed? These configurations define the reuse route, the assurance level, and the handover requirements before procurement, not during it.

Overview
We define reuse class, risk drivers and end use, then map the smallest diagnostics that change a decision, so the configuration is ready for supplier pricing with quality checks and O&M planning.

Treated Water IconWhich configuration fits your project?

Each configuration packages a reuse route, from source and polishing through to end-use routing, monitoring, and handover requirements, so the scope is ready for supplier pricing before procurement begins. Find the one that matches your end-use and assurance level. If none fits exactly, the enquiry form will get you to the right place.

FlowPlan(TSE+) Icon

FlowPlan - TSE+ (treated sewage effluent reuse)

Project: Reuse of treated sewage effluent

Suitable for: When treated effluent is already available and the next decision is how far to polish it for the reuse duty in view, whether irrigation, cooling makeup, washdown, or another outlet. This route is used where water savings, freshwater substitution, or discharge cost reduction are the driver and the reuse class, monitoring plan, and distribution basis still need to be set before the layout is scoped.

Features: Micra+, Clari+, Oxiclear+, FlowPlan - UFRO+ where higher-assurance polishing is needed

Delivers: Reuse class confirmed, end-use matched to the treatment route, and the distribution and monitoring basis set, ready for supplier pricing before any reuse infrastructure is procured.

FlowPlan(Dual+Reuse) Icon

FlowPlan - Dual+Reuse (two outlet reuse design)

Project: Enable dual plumbing reuse systems

Suitable for: When two reuse streams or two reuse duties need to be planned as one job, often around greywater and blackwater segregation, separate outlet areas, or different storage and pumping needs. This route is especially important where a building or campus must decide early whether the project is a new build or a retrofit and how the flows can actually be kept separate.

Features: GWTP, Batch+, greywater and blackwater segregation logic, dual distribution review

Delivers: Both reuse streams scoped together, collection and segregation logic checked, outlet layout defined, and a monitoring plan set across both outlets before procurement begins.

FlowPlan(ZLD+) Icon

FlowPlan - ZLD+ (zero liquid discharge pathway)

Project: Achieve Zero Liquid Discharge

Suitable for: When an industrial site is being pushed by discharge restriction, concentrate disposal cost, or a near-zero discharge requirement and the project depends on how brine, salts, energy, and solids will be handled. This is usually an industrial concentrate-management job, not the same reuse decision used for municipal TSE routing.

Features: ZLD+Prep+, ROCore+ where concentration by RO is viable, Sludge Dewatering, brine and solids route planning

Delivers: ZLD pathway scoped, brine and solids handling route defined, utility demand mapped, and viability checked before capital is committed.

Confirm your reuse configuration

Work through end-use, assurance level, and key project conditions below. TSE / UFRO, Dual+Reuse, and ZLD do not start from the same trigger. Use this guide to identify the right starting route before reaching out.

Pathway guide for treatedwater reuse

Reuse outcomes don’t start at the tertiary membrane polishing stage. They start with a clear end-use, a practical risk position, and an upstream treatment baseline that can hold steady under flow and load swings. This guide helps confirm the applicable reuse configuration and define the next decision step.

Quick definitions: TSE = Treated Sewage Effluent used for reuse duties such as irrigation, washdown, cooling makeup, or similar outlets; UFRO = higher-assurance polishing added where the reuse duty needs it; Dual+Reuse = two streams or two reuse outlets designed together, often around greywater and blackwater separation; ZLD = Zero Liquid Discharge, usually an industrial route driven by concentrate, salts, utilities, and solids handling.

Start with end-use Set assurance level Confirm connections

Typical reuse end-uses: cooling makeup, irrigation/landscaping, process reuse, lake recharge, washdown/utility water.

1) Define the reuse duty and the checks that follow

The same reuse scheme can serve very different duties. We line up the end-use with the level of polishing, monitoring, and operating control the site actually needs.

  • Standard reuse duty: irrigation, washdown, lake top-up, or similar outlets where steady quality and manageable operation matter most.
  • Higher-assurance duty: cooling makeup, process reuse, or other outlets where salt, scaling, or risk screening can push the job toward FlowPlan - UFRO+.
  • Two-outlet duty: sites that need two reuse qualities or two separate outlets planned together, often around greywater and blackwater separation or phased building connections.

2) Choose the right pathway

End-use and polishing depth

FlowPlan - TSE+ / FlowPlan - UFRO+

Where treated effluent already exists and the decision is how far to polish it for irrigation, cooling makeup, washdown, or another reuse duty. Water savings, freshwater substitution, and discharge cost reduction usually decide whether TSE alone is enough or FlowPlan - UFRO+ needs to be added.

Two streams and two outlets

FlowPlan - Dual+Reuse

Applicable where greywater and blackwater, or two separate reuse outlets, have to be planned together. New build versus retrofit, available flows, storage space, and outlet locations all change how the system needs to be laid out.

Industrial brine and disposal route

FlowPlan - ZLD+

On industrial sites where regulation, disposal cost, or a near-zero discharge target is driving the project, the hard part is usually brine, salts, energy, and solids handling, not the same treatment logic used for TSE reuse.

3) Define connections early

We capture the key inputs that decide whether the pathway is commercially sound: upstream variability, space and retrofit connections, operator tolerance, and where the reject and solids go.

Not sure which reuse route fits?

A single project can involve more than one of these routes, but they do not start from the same decision. FlowPlan - TSE+ / FlowPlan - UFRO+ is usually driven by the reuse duty, water savings, and discharge reduction. FlowPlan - Dual+Reuse is driven by source segregation, layout, retrofit versus new-build conditions, and where each outlet can actually go. FlowPlan - ZLD+ is usually an industrial discharge-control project driven by regulation, utilities, brine, salts, and solids handling. Tell us what is driving the job and we will point you to the right starting route.

Start an enquiry Back to configurations
TSE / UFRO route. Where treated effluent already exists and the aim is freshwater saving, reuse expansion, or lower discharge cost, define the reuse duty first. That decides whether straightforward TSE polishing is enough or whether FlowPlan - UFRO+ needs to be added.
Dual+Reuse route. In buildings and campuses, the early questions are greywater and blackwater separation, whether the job is a new build or a retrofit, actual flow balance, storage, and where the reuse lines can go.
FlowPlan - ZLD+ route. On industrial sites, the trigger is usually discharge restriction, disposal cost, or a near-zero discharge requirement. The key questions are brine, salts, energy, and solids handling, not the same routing logic used for TSE reuse.

Quick enquiry

Share the reuse target or discharge constraint, the water source, and the site conditions affecting the project. We’ll identify whether the starting route is FlowPlan - TSE+ / FlowPlan - UFRO+, FlowPlan - Dual+Reuse, or FlowPlan - ZLD+ and turn it into a clear scope with the right monitoring, operating, and utility requirements.

  • Project driver: reuse saving target, discharge reduction, or industrial discharge restriction
  • Water source and variability: treated effluent, greywater and blackwater split, or industrial concentrate / brine
  • Required outlet or discharge result: cooling, irrigation, process reuse, recharge, dual outlets, or near-zero discharge
  • Layout and operating limits: retrofit or new build, segregation, storage, monitoring expectations, and operator constraints
  • Utilities and residuals: space, power, chemicals, heat, and any concentrate, brine, salts, or solids route that has to be managed
  • Commissioning and sampling needs, including who will run the system and what checks have to be completed before operation
