Hospital and Healthcare Decontamination Services

Independent Testing Services

Regular measurement and testing of hospital wards, theatres, laboratories, rooms and equipment is vital in monitoring and checking of bacteria levels in the decontamination process.

Contaminated Site Solutions can offer this as a regular, independent service that’s able to identify the build-up of harmful organisms before an outbreak occurs.


Our hygiene monitoring system measures the level of contamination in seconds

Ultrasonic Cleaning Service

Contaminated Site Solutions Ultrasonics system uses the application of mechanical sound waves to the cleaning process. Ultrasonic cleaning is state-of-the-art technology. It utilizes a digital generator powering transducers submerged in a tank of hot water.

Single or multiple items can be sterilised, as a regular service and also when tests identify the presence of harmful organisms. As our team is experienced in working in busy   hospital wards, there’s minimal disruption to the hospital.


Contaminated Site Solutions’ ultrasonic cleaning machine can help avoid disruptive Healthcare Associated Infections (HCAI) outbreaks.

HPV Decontamination Technology

Hydrogen Peroxide Vapour (HPV) decontamination technology provides hi-tech room bio-decontamination equipment and services to the healthcare sector.

Our technology is an important tool in the battle with Healthcare Associated Infection (HCAI), targeting and eliminating environmentally-associated infection.

With the HPV system Waitakere Hospital will be using the most up-to-date decontamination technology available worldwide.


The HPV system eliminates pathogens from all surfaces including sensitive and expensive electronic equipment.

What are the benefits to Hospitals and DHBs?

  • hospitals-imgHPV decontamination technology and Ultrasonic cleaning are more effective than traditional cleaning techniques.
  • The HPV decontamination technology isn’t just more effective than regular cleaning – it’s also quicker. That means quicker turnaround of operating theatres, which in turn could allow more surgical procedures to be carried out, and therefore minimise hospital waiting lists.
  • Superbug outbreaks can be prevented and treated before they become serious.
  • Fewer superbug outbreaks mean less disruption to Waitakere Hospital.
