Water Supply & Distribution Design

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 Prevention & Water Safety

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.

Drainage & Wastewater Management

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.

Specialist Water Systems & Equipment Integration

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.
