Case Study

Refining best practice in changeable circumstances

Client:
Birmingham Airport
Sector:
Aviation
Product used:
SOLution
Project overview:
The Birmingham Airport is constantly looking to reduce energy usage whilst looking for best practices in the operation of their water hygiene regime. During the recent COVID-19 pandemic the profile of the water usage at the airport changed dramatically with a reduction in the number of passengers travelling through the airport, this led to a significant reduction in water usage and turnover of the water systems. Part of the initial reactions to this was to increase flushing and to undertake regular disinfections of those areas where members of the public were in contact with the water systems. This was a very labour-intensive process to implement and manage with the constantly changing scenarios at the airport relating to the changes in COVID rules.

The Challenge

The challenge was to automate the flushing at the same time as being able to monitor temperatures and flows in order to provide the data to prove compliance and in addition to link into the process a proportional dosage system to allow the introduction of a potable grade biocide to enable either intermittent or on-going permanent sanitisation option.

Approach

Waterman suggested the installation of the SOL automated flushing and temperature monitoring on the South Terminal furthest hot and cold water outlets linked to a proportional dosing unit on the incoming water supply to the South Terminal. The SOLution units provide the measurement of water flow, usage and temperature monitoring so that the data on usage can be evaluated and then automatic flushing via the SOLflush units is based upon the usage profile ensuring there are no periods of stagnation. The dosing system then operates whenever the SOLflush flushing system operates to introduce a potable biocide into the water system which is then distributed throughout the hot and cold water system by the automated flushing process.

Results

The results to date indicate that the periods of regular low usage have been eradicated and we have undertaken some manual disinfection with the SOL system pulling the potable grade biocide through the terminal. This has resulted in a very good microbial profile from the recent sampling results. The installation of the dosage system is yet to be fully completed as the proportional link from the water meter is inoperable and we are waiting for the delivery of a replacement before the dosing system becomes operational

Case Study

Remotely improving water flow in the healthcare sector

Client:
Princess Alexandra Hospital
Sector:
Healthcare
Product used:
SOLution & SOLflush
Project overview:
The Princess Alexandra Hospital have been experiencing low water usage & turnover in a specific treatment area. This area is a treatment centre for cancer care with daycare patients using the facility. During the recent COVID-19 pandemic the usage of the area changed dramatically with much lower numbers of patients using the facility at any one time thus leading to a significant reduction in water usage and subsequently Legionella bacteria being identified within the system. This unit is situated remotely from the main hospital, so the distance the water travels to enter the facility is quite lengthy exacerbating the low use and temperature control issues.

The Challenge

The challenge was to resolve the low and intermittent water usage and be in a position to have records to prove water flow and temperature were improved and compliant. In addition to linking into the process a proportional dosage system to allow the introduction of a potable grade biocide to enable either intermittent or ongoing permanent sanitisation options, which would minimise the growth of Legionella bacteria.

Approach

Waterman approached this issue with the SOL system to be installed at the furthest outlets on both the hot and cold water systems in the Williams Day Unit linked to a proportional biocide dosing unit on the incoming water supply to the treatment centre. The SOLution units provide the measurement of water flow, usage and temperature monitoring so that the data on usage can be evaluated and then automatic flushing via the SOLflush units is based upon the usage profile ensuring there are no periods of stagnation. The dosing system then operates whenever the SOLflush flushing system operates to introduce a potable biocide into the water system which is then distributed throughout the hot & cold water system by the automated flushing process providing system sanitisation of the hot & cold water.

Results

The results to date indicate that the temperatures in the area are now compliant and that the periods of regular low usage have been eradicated.

Even though the installation of the dosage system is yet to be fully completed, there has been a significant improvement in the Legionella monitoring results. It is anticipated that when the installation of the dosage system is complete then Legionella bacteria will be completely eradicated from the system.
