structural situations, providing trouble-free performance in themost arduous of conditions.
Additionally, the benefits of clay piping go even further than longevity and can even make ongoingmaintenancemuch easier. The claymaterial canwithstand extremely high pressureswhen it comes to jetwashing, ensuring any blockages can be cleared and regularmaintenance carried outwithout any trouble. This gives contractorsworking on brownfield sites reassurance that they are investing in a high-quality, sustainable
solution that theywon’t have to spend further costs on for replacements or extensive repairs in the future.
Sustainable newbuilds for the future
With the ongoing housing crisis and growing UK population, it’s clear thatmeasures need to be put in place to address housing needs. In England alone, it’s been predicted that three million newhomesmust be built over the next 20 years to combat the shortage,meaning the pressure is on to find areaswhere these new homes can be built. Brownfield sites are
becoming amore attractive proposition as land becomes available,making it vital that engineers considerways to ensure these new sites are safe, reliable and attractive places to live.
Choosing a high-quality drainage solution, like clay piping, is a key consideration during the process of developing brownfield sites, whether that be for a residential or commercial project. By choosing the correct below-ground drainage, you can ensure eco-friendliness, low costs and long-termsustainability for a project, allwithout compromising on quality.
South West Water to use I-Phyc’s algae-based treatment
SouthWestWater is installing Industrial Phycology (I-Phyc)’s algal technology to remove phosphorous (P) in the final effluent at Broadwindsor Sewage TreatmentWorks.
The scheme is part of SouthWestWater’s drive to innovate and deliver P removal schemes for small rural communities, as I-Phyc is currently thought to be the only viable technology that is able to remove, not only Phosphorous, but also Ammonia and almost all harmful trace contaminants including pharmaceutical compounds, plasticisers, insecticides,metals, flame-retardants, biocides, persistent organic pollutants and steroids. I-Phyc is able to consistently remove between 50%and 99%of these pollutants and SouthWestWaterwill bemonitoring removal rates at Broadwindsor.
The unique and innovative technology, developed by I-Phyc, utilises a natural process using algae to biologically treat wastewater.
Algae are known for their ability to remove pollutants. Eutrophication, the process of

algae growing naturally inwatercourses, is caused by an excess of nutrients and particulates the algae can feed on. By harnessing the eutrophication process and deliberately applying it on thewastewater treatment site in a controlledway, pollutants are removed before final effluent is discharged to thewatercourse,withmuch higher efficacy than alternative treatment solutions. It’s also significantlymore environmentally friendly, requiring no potentially harmful chemical addition.
Russell Bright, CEO of Industrial Phycology, said: “We see this as a significant step forward in the use of algae to treat sewage in a natural and sustainableway that hasmany advantages over current technology.
“With over 900WINEP schemes across the UK water companies requiring the removal of phosphorous to very lowlevels, the technology is away of breaking away from thewater industry’s reliance on chemical usage (typically ferric). This is positive news as chemicals carrywith thempotential safety

and environmental risks, added to this is the increased demand and volatile price.
“Algal technology has no such drawbacks, it locks away carbon in the bodies of the algae, creates no sludge and produces a feed stock for sustainable products.”
MarkWorsfold Director of Asset Management at SouthWestWater Limited said: “Likemostwater companies, South WestWater is looking to innovate and deliver newtreatment processes for P reduction as part of our investment programme, I am really excited about the I-Phyc technology and howthismay deliver sustainable low cost solutions for smaller treatment catchments.”
