Wastewater Treatment Design

We’re not incentivised to specify particular brands or systems. Our recommendations are based purely on technical suitability, cost-effectiveness and long-term performance for your specific project.

From single-property package plants to municipal-scale bespoke works, we design across all scales. Experience from small domestic systems to complex industrial applications informs appropriate technology selection and realistic performance expectations.

When WCI Consulting Engineers design drainage, WCI Project Engineers can construct it and WCI Service Engineers can maintain it long-term. This vertical integration means complete accountability – no finger-pointing between designer and contractor when challenges arise.

As part of WCI Group, we understand what works in practice. Our designs can actually be built efficiently and maintained effectively – we’ve constructed and serviced thousands of treatment systems, providing knowledge that prevents theoretical designs unbuildable or unmaintainable in reality.

Treatment works operate for decades. We design for capital cost, operational efficiency, maintenance practicality and long-term reliability – optimising total life value, not just upfront expenditure. WCI Service Engineers maintain systems long-term, so we design with operational reality firmly in mind.

If WCI Consulting Engineers design your treatment works, WCI Project Engineers can construct it and WCI Service Engineers can commission and maintain it throughout its operational life. This vertical integration means complete accountability from concept through decades of operation.

Larger developments, industrial applications, and municipal projects often require purpose-designed treatment works:

• Preliminary Treatment
• Primary Treatment
• Secondary (Biological) Treatment
• Tertiary Treatment
• Sludge Management

Standard strength design based on population equivalent and typical flow patterns. Design accounts for diurnal variations and weekend/holiday fluctuations.

Hotels, restaurants, care homes with higher organic loads, fats/oils/grease, and variable flow patterns requiring robust process design and adequate buffering.

Food processing, manufacturing with specialist treatment addressing high BOD, specific contaminants, pH variations, or temperature extremes. May require pre-treatment before biological processes.

Combined domestic and commercial/industrial – treatment design accommodating varied inputs with appropriate buffering and process resilience.

Residential, commercial and mixed-use developments requiring private wastewater Treatment design integrated with your site masterplanning and architectural proposals. We coordinate treatment works location, visual impact, and access requirements with your design intent while satisfying regulatory requirements.

Hotels, care homes, food processors and industrial facilities requiring treatment design for new facilities, expansions or upgrades to existing systems. Our industrial wastewater experience addresses specialist requirements.

Local authorities, education, healthcare and defense estates requiring treatment design for new infrastructure or existing works upgrades, with appropriate quality assurance and professional indemnity.
