NOVTRIQ designs water supply systems delivering appropriate flow and pressure to all building zones whilst ensuring water quality, preventing backflow, and minimising energy consumption. Systems are designed for peak demand scenarios with appropriate storage and boosting provision. We apply hydraulic modelling to verify pressure availability across all demand points and identify appropriate valve and equipment sizing.
Water quality protection includes appropriate treatment, pressure maintenance, and segregation strategies preventing contamination of potable supplies. Metering and monitoring systems enable occupants to identify consumption patterns and manage water resource efficiently. For multi-zone facilities, we design zoned distribution networks with appropriate pressure reducing valves ensuring even supply and preventing equipment damage from excessive pressure.
Legionella bacteria present significant health risks within water systems particularly in hot water and cooling circuits. NOVTRIQ designs water systems incorporating temperature management, flow velocity, and material selection to suppress bacterial growth and biofilm formation. Design incorporates regular flushing of dead legs, regular monitoring, and maintenance protocols supporting occupant safety. For healthcare facilities, we design systems fully aligned with HTM 04-01 (Safe hot water and surface temperatures) requirements.
Risk assessment identifies appropriate water treatment, system monitoring requirements, and staff training needs. We specify materials, pipework configuration, and operational procedures preventing scale formation and creating conditions unsuitable for bacterial proliferation. Regular water sampling and monitoring procedures ensure microbial safety throughout system life.
Effective drainage removes foul and surface water efficiently whilst preventing backflow, surface flooding, or contamination of water bodies. NOVTRIQ designs drainage networks with appropriate pipe sizing, gradient, and access provision for maintenance and cleaning. Separate foul and surface drainage systems simplify treatment and disposal. Design incorporates appropriate storage and treatment where municipal sewerage is unavailable.
Sustainable drainage principles are applied including rainwater harvesting and reuse where feasible, permeable surfaces, and natural infiltration reducing pressure on municipal systems. Drainage performance is verified through hydraulic modelling under design storm conditions ensuring systems provide appropriate flood resilience.
Beyond basic supply and drainage, many facilities require specialist water systems including hot water generation and distribution, chilled water for cooling systems, medical gas supply integration, and equipment-specific requirements. NOVTRIQ specifies appropriate water heaters, storage vessels, and distribution networks supporting both peak demand and efficient operation at part load. Integration with heating systems ensures efficient hot water generation whilst maintaining safety temperatures and managing energy consumption.
Water supply systems designed in full compliance with Building Regulations Part G (Sanitation, drainage and waste disposal) and Water Regulations 2016. Healthcare facilities designed to HTM 04-01 (Safe hot water and surface temperatures) and HTM 05-02 (Medical gas). The Legionella Approved Code of Practice and guidance on managing health and safety risks from Legionella bacteria in water systems informs design and operation. Water quality to European standards adopted as baseline for UK public water supplies.
Water Supply Directive 2015/2184 requirements for water safety and quality. EN 806-1 principles for internal water installations and EN ISO 1167 for plastic piping systems. EN 12098 building automation and controls standards for system monitoring. EN 15288-1 design and installation of thermal solar systems for potable hot water generation.
ISO 7730 principles for thermal comfort including adequate hot water availability. ISO 14644 standards for cleanroom water quality where applicable. ASME standards adopted for pressure vessel design and certification ensuring global best practice and safety assurance.
Water supply and drainage are essential infrastructure impacting occupant health, operational efficiency, and environmental responsibility. We'll design systems that ensure safety compliance, reliable service, and efficient resource management throughout facility operation.
