Post Pandemic concerns arising from stagnant, underused and under-maintained water systems during national lockdowns.

As we approach the post-pandemic re-opening of buildings across our towns and cities, several challenging factors, never experienced before, have impacted water management practice. This results in difficult questions for those responsible for business premises maintenance and upkeep, along with environmental microbiologists, infection prevention consultants, and those engaged in the wider water hygiene industry.

The Problem

In recent times closure of premises enforced by government restrictions in the fight against Covid-19 have been widespread across the United Kingdom and the rest of the world.

The necessity of this act was a responsible approach to reducing the spread of Covid-19 and the strategy has proved to be a highly effective control measure for protecting the population. Whilst this measure had an impact on protecting our healthcare system, the resulting underuse of buildings and their water systems has given rise to a different risk; that of waterborne microbial colonisation and contamination.

The enforced shut down and stagnation of water systems will have inadvertently created ideal growing conditions for a range of harmful bacteria. Without an effective water safety plan, waterborne bacteria and pathogens present a significant risk as we begin to see buildings reopen due to the governments relaxing the restrictions. Many water safety plans do not take into consideration buildings having long periods of shutdown as they were never designed for this eventuality.

It is reasonable to assume that routine maintenance and management of water systems may also have suffered as the pandemic forced our focus and our priorities elsewhere. Water Stagnation and a lack of appropriate temperature control are key factors that can help to promote the growth and build-up of biofilm within water systems. The biofilm which can be found across all areas of the hot and cold-water system, and throughout the building as a whole, support the growth and proliferation of water pathogens including, amongst others, Pseudomonas spp. and Legionella spp.
