Modular treatment units for remote areas, subdivisions, and cluster developments.
CFD, P&ID, SCADA and commissioning for critical water treatment plants.
Plant layouts, piping isometrics and construction-ready engineering drawings.
Flow, mixing and thermal CFD across treatment and process equipment.
Full mechanical, physico-chemical, biological and sludge equipment range.
Decentralised systems treat wastewater close to the source, eliminating the need for extensive sewer infrastructure. Thi
Every system is designed for your specific wastewater characteristics, flow profile, and effluent targets. No off-the-shelf assumptions — just validated process engineering.
Equipment selected from manufacturers with proven field performance in similar applications. Duty/standby arrangements and robust construction minimise unplanned downtime.
Design targets are set at 50-70% of consent limits, providing a safety margin for process variation. Continuous monitoring and automated reporting demonstrate compliance.
Intuitive controls, clear instrumentation, and accessible maintenance points reduce training requirements. Standard operating procedures written in plain language.
Direct access to our process engineers for operational advice, troubleshooting, and optimisation. Remote diagnostics and rapid on-site response keep your plant running.
Materials certified to EN 10204 3.1, welding procedures qualified to ISO 9606, and pressure testing to 1.5x design pressure. Full traceability from mill to commissioning.
Our modular treatment units can serve individual homes, small clusters, or entire subdivisions. Units can be added as de
Laser scanning, utility mapping, and soil investigation inform the design. We account for existing infrastructure, access constraints, and future expansion needs.
Mass balance, hydraulic, and process models size equipment correctly for peak, average, and minimum flow conditions. Over-design wastes Capital expenditure; under-design fails.
Revit and SolidWorks models show exactly how equipment fits in the available space. Clash detection resolves pipework conflicts before steel is cut.
Hazard and operability studies identify process safety risks, environmental releases, and equipment failure scenarios. Mitigation measures are designed in from the outset.
Independent chartered engineers review calculations, drawings, and specifications. Third-party verification adds confidence for boards, lenders, and insurers.
Constructability reviews during design identify operational benefits and programme efficiencies. Early contractor involvement prevents expensive surprises during installation.
Decentralised systems are used for rural homes, recreational facilities, remote industrial sites, and new developments w
Treatment for cooling towers, boilers, and process make-up. Removes hardness, silica, and organics to prevent scaling, fouling, and corrosion in heat transfer equipment.
Effluent treated to crop-safe standards for irrigation of cereals, vegetables, and fodder. Nutrient content reduces fertiliser requirement while pathogen removal protects food safety.
Treated water for HVAC make-up, toilet flushing, and landscape irrigation in commercial and residential developments. Reduces municipal water demand and sewer loading.
Recycled wash water with oil separation, solids removal, and disinfection. Closed-loop systems reduce freshwater use by 80-90% in commercial truck and bus wash facilities.
Treated wastewater suitable for haul road and demolition dust control. Basic solids removal and pH adjustment sufficient for this non-potable, non-contact application.
Highly treated effluent used to replenish groundwater reserves. Requires advanced treatment including reverse osmosis and disinfection to meet drinking water standards.
Large-scale centralised wastewater treatment plants for cities and municipalities.

View PageMunicipal wastewater treatment protects public health and receiving waters by progressively removing solids, organic matter, nutrients, and pathogens from sewage. Our engineered solutions address the unique challenges of municipal flows including diurnal variation, stormwater ingress, seasonal population changes, and increasingly stringent discharge standards.
Screening, grit removal, and flow equalisation protect downstream processes from damage and overload.
Gravity separation of settleable solids achieving 50-70% TSS and 25-40% BOD removal.
Activated sludge, MBBR, or SBR processes remove dissolved organics and enable nutrient control.
Filtration, UV, or chemical disinfection guarantees compliance with bathing water and reuse standards.
