  • Mains Water Utility Connections (via licensed providers)
  • Domestic Hot Water Systems
  • Domestic Cold Water Systems
  • Above Ground Drainage systems

 This includes the following functions: Design, selection and specification of Cold Water Storage Tanks, Cold Water Booster Sets and associated Expansion Vessels / Pressure Safety Valves, Domestic Hot Water Cylinders (Calorifiers) and External Heat Exchangers,  Domestic Hot Water Return Pumps, Thermostatic Domestic Hot Water Return flow controls, Domestic Hot and Cold distribution pipework. All designs are conducted in accordance with HSE ACOP L8 - Legionnaires disease - the control of Legionella in water systems.

No Public Health Engineering design would be complete without the associated controls system. The symbiotic relationship between a public health service and its controls is often overlooked or ignored, particularly if this requires the coordinated response of multiple functions in sequence. Callidus Design have controls expertise in house and therefore all our public health designs are accompanied by a fully coordinated controls design package.
