Plumbing & Public Health Engineering
Wastewater, Stormwater, and Water Supply Solutions
At EnviroSpan Engineering, we provide end-to-end plumbing and public health engineering services designed to ensure safe, efficient, and code-compliant water management in buildings of all types. Our expertise spans the full lifecycle of plumbing system design and installation—from water supply to wastewater and stormwater discharge—delivered with a focus on sustainability, hygiene, and long-term performance.
We serve a wide range of sectors including residential, commercial, healthcare, hospitality, and education—delivering robust solutions that align with UK Building Regulations, CIBSE guides, and Public Health Engineering best practices.
Potable Water Supply Systems
We design and install complete cold and hot water distribution systems tailored to building size, usage, and pressure requirements. Systems are designed for maximum efficiency, pressure balancing, and hygiene, incorporating features like:
- Boosted cold water systems
- Domestic hot water circulation loops
- Solar water heating integration
- Anti-scald protection and temperature regulation
- Legionella control and compliance with HSE guidance
Materials are selected for durability, performance, and compliance with WRAS standards. We also integrate water metering and monitoring to support conservation and BREEAM Wat credits.
Wastewater & Soil Drainage Systems
We design and implement safe, reliable systems for the disposal of greywater and blackwater from sanitary appliances. Our solutions include:
- Above-ground and below-ground drainage networks
- Ventilation and trap seal protection
- Backflow prevention devices
- Grease traps and interceptors for commercial kitchens
- Sewage lifting stations for low-lying sites
- Coordination with MEP and structural systems to prevent service clashes
All drainage systems are developed to meet Part H of the Building Regulations and BS EN 12056 standards.
Stormwater Management Systems
Sustainable and effective stormwater handling is a growing priority in modern construction. At EnviroSpan, we design stormwater drainage systems that address both capacity and environmental impact. Our services include:
- Roof and surface water drainage
- Rainwater harvesting systems
- Sustainable Drainage Systems (SuDS)
- Attenuation tanks and soakaways
- Flow control devices and non-return valves
- Coordination with landscaping and civil drainage systems
We ensure compliance with local authority requirements and assist with drainage strategy reports for planning submissions.
Public Health Engineering Integration
Our plumbing and drainage designs are fully integrated with architectural and structural layouts to minimise conflicts and ensure maintainability. We coordinate closely with mechanical and electrical services to ensure seamless installation and compliance with all project-specific requirements.
We also provide:
- Riser and plantroom layout optimisation
- Prefabrication-ready drawings for off-site construction
- System zoning for high-rise and complex developments
- Detailed specifications and material submittals
- Maintenance access planning and pipe insulation strategies
