Water utilities and councils face a dual challenge in managing reticulation water pipelines: ensuring the quality of potable water and maximising the lifespan of infrastructure assets. One of the most insidious threats to both goals is biofilm formation within pipelines. Biofilms, while invisible to the naked eye, have a profound impact on water quality, public health, and the structural integrity of pipelines. Fortunately, innovative solutions offer a transformative way to combat biofilms and secure long-term economic and operational benefits.
Understanding Biofilms: What Are They and Why Do They Matter?
Biofilms are complex microbial communities that adhere to surfaces, forming slimy layers on the inner walls of water pipelines. These structures consist of bacteria, fungi, and other microorganisms embedded in an extracellular polymeric substance (EPS) matrix. The formation of biofilms in drinking water systems is influenced by factors such as nutrient availability, microbial species, and environmental conditions.
While biofilms may seem harmless, they carry significant risks. They can:
- Harbor Harmful Pathogens: Opportunistic pathogens like Legionella and Pseudomonas can thrive within biofilms, potentially contaminating drinking water and posing serious public health hazards.
- Promote Biocorrosion: Microbial activity within biofilms accelerates the degradation of pipe materials, causing structural damage and reducing pipeline lifespan.
- Impede Water Flow: The accumulation of biofilms narrows the pipeline’s effective diameter, increasing resistance, lowering efficiency, and leading to higher energy costs for water distribution.
The Economic Toll of Biofilms
Left untreated, biofilms can significantly shorten the lifespan of water pipelines. The biocorrosion caused by microbial activity weakens pipe walls, increasing the likelihood of leaks and bursts. Repairing or replacing damaged pipelines is not only costly but also disruptive to communities. Moreover, the energy inefficiencies caused by biofilm-induced flow restrictions drive up operational costs for utilities.
Beyond infrastructure impacts, the presence of biofilms poses regulatory and reputational risks. Utilities are held accountable for maintaining water quality standards, and failure to address biofilm-related contamination could result in fines, public backlash, and loss of consumer trust.

NO-DES Mains Cleaning: A Game-Changer in Biofilm Removal
Innovative technologies like NO-DES Mains Cleaning offer a proactive and effective solution for biofilm removal. Unlike traditional methods such as air scouring or flushing, NO-DES systems are non-invasive and environmentally responsible. The process involves circulating water through a closed-loop filtration system, which removes biofilms, sediment, and other impurities without wasting water.
Key benefits of NO-DES cleaning include:
- Enhanced Water Quality: By eliminating biofilms, NO-DES reduces the risk of pathogen contamination, ensuring safer potable water for consumers.
- Extended Asset Lifespan: Removing biofilms prevents biocorrosion, preserving the structural integrity of pipelines and delaying the need for costly replacements.
- Cost Efficiency: The non-invasive nature of NO-DES cleaning minimises downtime and disruption, while the water-saving approach lowers operational expenses.
- Environmental Sustainability: NO-DES avoids the wastage associated with traditional flushing/ice pigging methods, aligning with global sustainability goals.
A Simple Solution with Lasting Impact
The removal of biofilms using NO-DES mains cleaning is not only an innovative maintenance practice but also a strategic investment in the future of water networks. By adopting this technology, utilities and councils can extend the life of their assets by years, significantly reducing the total cost of ownership. Moreover, improved water quality enhances public health outcomes and boosts consumer confidence in water services.
The Path Forward: Proactive Asset Management
To remain resilient in the face of aging infrastructure and rising operational challenges, water utilities and councils must prioritise proactive maintenance strategies. Technologies like NO-DES demonstrate that addressing biofilm formation is not only feasible but also highly beneficial. The economic, environmental, and public health advantages make it a compelling choice for modern water network management.
By embracing innovative solutions to biofilm removal, utilities can protect their infrastructure, safeguard water quality, and secure a sustainable future for the communities they serve.
