Compliance limits tightening but the upgrade pathway isn't scoped? Procurement moving before connections are defined? These STP and ETP configurations take the project from treatment selection and sizing basis through to vendor-ready scope and commissioning checks.
Which configuration fits your project?Each configuration maps a treatment pathway from feed and constraints through to vendor-ready scope, with sizing basis, connection register, and commissioning requirements defined before procurement. Find the one that matches your plant type and project situation. If none fits exactly, the enquiry form will get you to the right place.
Project: New Sewage Treatment Plant planning
Suitable for: When a new STP is needed or an existing plant can’t meet tightening consent limits, treatment route and sizing basis need to be defined before vendors are engaged.
Features: MBBR+, Clari+, Sludge Composting, Sludge Reuse Plan
Delivers: Compliance pathway and treatment route defined, sizing basis and connection register vendor-ready, and commissioning and handover requirements set early.
Project: Effluent Treatment for industrial facilities
Suitable for: When process variability, inhibition risk, or discharge cost is the driver and the treatment basis needs to be defined before any technology or vendor is selected.
Features: Batch+, Oxiclear+, Sludge Dewatering, ROCore+
Delivers: Process risk mapped, compliance pathway confirmed, treatment route and connections defined, and vendor-ready scope with commissioning requirements set before procurement starts.
Project: Upgrade and performance expansion of STPs
Suitable for: When performance is below target or capacity needs to grow but the plant must keep running, connections, phasing, and commissioning requirements need to be defined before works are scoped.
Features: MBBR+, Clari+, Sludge Reuse Plan, ROCore+
Delivers: Retrofit scope defined, hydraulic and process connections mapped, phasing plan confirmed, and KPIs set so commissioning has a clear performance basis.
Project: Retrofit of industrial effluent systems
Suitable for: When an industrial plant is underperforming or process changes have shifted the load profile and the upgrade pathway hasn’t been engineered.
Features: Batch+, Sludge Dewatering, ROCore+, Oxiclear+
Delivers: Retrofit pathway defined, flow rebalance and connection constraints mapped, and risk position assessed before any scope is issued to contractors.
Project: Higher-assurance polishing for reuse, UF + RO configured around end-use risk, upstream pretreatment, and membrane commissioning criteria.
Suitable for: When reuse quality targets require polishing beyond secondary treatment and the membrane route, pretreatment basis, and commissioning criteria need to be defined before procurement.
Features: Micra+, ROCore+, Oxiclear+
Delivers: Reuse quality basis confirmed, membrane configuration and pretreatment requirements defined, and commissioning requirements set before any system is specified or procured.
STP and ETP can both lead to discharge and reuse outcomes, but they do not begin from the same operating conditions. STP work is usually driven by municipal duty, steady loading, nutrient handling, and practical plant operation. ETP work is usually driven by process chemistry, variable loads, pretreatment needs, inhibition risk, and factory uptime. We support both, but the treatment basis, checks, and configuration path should match the wastewater source before any option is selected.
Municipal sewage projects where public health, operator simplicity, and stable plant performance determine the treatment route.
Industrial effluent projects where process variability, chemistry, pretreatment, and reuse risk decide the treatment route.
Use this guide to confirm your project situation, define the intended outcome, and identify the configuration that matches before reaching out.
Treatment outcomes don’t start at the treatment stage. They start with a clear intent (discharge, reuse, or resilience), a clear risk position, and an operating baseline that can hold steady under flow and load swings. STP and ETP are determined by your water type and source, and the pathway follows from that. This guide helps confirm the applicable configuration and define the next decision step.
Quick definitions: STP = municipal sewage treatment; ETP = industrial effluent treatment; Retrofit = phased upgrades within a live plant; Procure = vendor-ready ToR/spec pack + evaluation logic; UFRO = higher-assurance polishing for reuse; ZLD = recovery where brine/solids handling defines feasibility.
Typical project intents: compliance upgrades, capacity expansion, industrial risk control, retrofit connections, and reuse readiness.
The same treatment upgrade can carry very different completion requirements. We map the intended outcome to the assurance level, monitoring position, and the information needed to confirm it.
Municipal pathway
FlowPlan - STP+
Municipal wastewater where flow patterns, nutrient duties, and operator simplicity need to be agreed early before the treatment basis is set.
Industrial pathway
FlowPlan - ETP+
Industrial effluent where process variability, inhibition risk, and pretreatment requirements must be resolved before any technology or vendor is selected.
Retrofit pathway
FlowPlan - STP Retrofit / FlowPlan - ETP Retrofit
Existing plant upgrade or expansion where continuity of operation is a constraint - connections, phasing, and commissioning sequence need to be defined before any works are scoped.
We capture the inputs that decide whether the pathway is commercially sound: upstream variability, space and retrofit connections, operator tolerance, and where residuals or sludge go when treatment changes.
Some projects follow one pathway from the start. Others need more than one route planned together. A site may carry both municipal sewage and industrial effluent, or it may already have a main treatment line in place with polishing added later for reuse. In those cases, the work needs to be sequenced properly. Identify the streams, confirm what is already installed, and decide what the plant must achieve. Once that is clear, we can map the treatment path, retrofit needs, and next step.
If you can share your influent context, operational constraints, and intent (discharge, reuse, or both), we’ll point you to the most relevant STP or ETP pathway - and the next best decision step. You’ll also get the core inputs needed to engage solution providers with confidence.
