An insight into some of our services

Water Hygiene and Plumbing Works

Water hygiene encompasses a wide range of services from the implementation and monitoring of written control schemes after a risk assessment to the upgrade or improvement of your water system.

PTSG specialists assist in providing what your premises need in terms of tried and tested methods of monitoring, cleaning, disinfecting and refurbishing your water systems. However, what sets us apart is our innovative approach – designing engineered control measures to comply with all the relevant legal requirements.

Our experienced plumbers approved by WIAPS (WRAS) scheme are qualified to undertake various mains water works for local water suppliers. Our mechanical engineering services comply with Water Supply (Water Fittings) Regulations 1999 and BS 8558:

  • Temperature monitoring

Mains Water Services

A water systems sampling service can encompass a whole range of applications from cooling water towers and cold water storage tanks to swimming pools and jacuzzis, humidifiers, dental equipment, emergency showers, closed water systems, water heaters and many more.

There is an important distinction between water sampling and water testing. Water testing is the process used for analysing the constituents or microbial content of the water. Water sampling is the action of sample collection and transportation. As they are separate services, there are separate British Standards for each.

In addition to the regular sampling for aerobic bacteria in cooling water, a routine monitoring scheme should also include periodic sampling for the presence of Legionella bacteria. This should be undertaken at least quarterly, unless sampling is necessary for other reasons, such as to help identify possible sources of the bacteria during outbreaks of Legionnaires’ disease.

Chlorination and dechlorination are carried out following a successful hydrostatic pressure test. It ensures and demonstrates that the pipework is hygienic and free from harmful contamination and pathogens such as E Coli, Coliform Bacteria, Enterococci and Clostridium Perfringes.

Our services cover:

  • Pressure testing
  • Chlorination/Dechlorination
  • Swabbing of new mains
  • Flushing
  • Water sampling
  • Digital certificates
  • Mains installation
  • Service connections
  • Groundworks and moling

Legionella-risk-assessment-scaled.jpg

Legionella Risk Assessment

We have a wealth of experience in conducting Legionella risk assessments across all industry sectors. Building owners are responsible for their work premises under the Health and Safety Act 1974.

They must carry out a risk assessment of the property or premises that assesses the risk of exposure to Legionella. We can make them aware of what Legionella is, what systems are hazardous and which are low-risk.

The HSE’s Approved Code of Practice (ACoP) L8 is a guideline document for the prevention and control of legionellosis in water systems and has a special legal status by which the employer can be prosecuted, fined or even imprisoned, if it is proved that you did not follow the relevant provisions of the Code.

Our risk assessment follows the guidance set out in BSEN 8580:2010 which gives recommendations on the assessment of the risk of legionellosis presented by artificial water systems. The assessment will conclude on the condition of plant and advise you of any remediation necessary in order to reduce the risk from Legionella bacteria.

Water-sampling-scaled.jpg

Water Sampling

A water systems sampling service can encompass a whole range of applications from cooling water towers and cold water storage tanks to swimming pools and jacuzzis, humidifiers, dental equipment, emergency showers, closed water systems, water heaters and many more.

There is an important distinction between water sampling and water testing. Water testing is the process used for analysing the constituents or microbial content of the water. Water sampling is the action of sample collection and transportation. As they are separate services, there are separate British Standards for each.

All legionella monitoring and sampling programmes for cooling towers and cooling water systems should include routine sampling and testing for the presence of bacteria including Legionella bacteria. The water testing procedures should include for both general (aerobic) bacterial species and more specifically Legionella bacteria.

In addition to the regular sampling for aerobic bacteria in cooling water, a routine monitoring scheme should also include periodic sampling for the presence of Legionella bacteria. This should be undertaken at least quarterly, unless sampling is necessary for other reasons, such as to help identify possible sources of the bacteria during outbreaks of Legionnaires’ disease.

Fogging-scaled.jpg

Eco Fogging

PTSG has a dedicated fogging division, with a team of qualified specialists for the control and decontamination of bacteria and viruses within various applications.

Applying our in-depth knowledge of bacteria controls and fogging technology, we deliver effective dry fogging disinfection solution for a wide variety of clients.

Ultra-Low Volume(UVL) dry fogging involves using 1-5 micron droplets of disinfection that will settle on all surfaces of many objects and inaccessible areas that may not be reached using conventional methods. Studies show the application of disinfection by aerosol significantly reduces the number of viable infectious airborne pathogens.

This is achieved by treating air quality and all touch point surfaces with a dry disinfection with minimal disruption.

On completion, we will verify disinfection with an Ensure touch hand-held monitor that will analyse a rapid test, measuring active growth of microorganisms through detection of Adenosine Triphosphate (ATP).

The cleaning and disinfection of key touchpoints, such as door handles, washroom facilities and shared surfaces is carried out to minimise the risk of microbiological contamination to help protect staff, customers and visitors providing a safer environment.
