A Publication in Water & Wastewater Treatment Magazine

October 8, 2019

Eleanor, our senior geoscientist has had an article published in the water & wastewater treatment magazine.

We’re thrilled to be published in Water & Wastewater Treatment (WWT) this month, with an article written by our Senior Geoscientist, Dr. Eleanor Raper. Eleanor specialises in wastewater and water treatment; the article she wrote for WWT is about the importance of reviewing your wastewater treatment system.


Wastewater treatment processes have often been overlooked, but increasingly stringent emissions limits mean that businesses are paying more attention to their wastewater treatment procedures. There is also an increasing awareness of the environmental impacts of pollutants in the water system. For example, an increase in understanding of eutrophication and its effects has led to lower emission limits for nitrogen and phosphate compounds. As well as being bound by stricter emissions limits, businesses should review their wastewater treatment systems to ensure efficiency and potentially save on costs.

Given that the inputs to a wastewater treatment system are highly likely to change over time and space, reviewing systems regularly is important to make sure that the processes are still appropriate. Treating wastewater can involve physical, chemical and biological processes, or a combination. Understanding the role of each stage and how it relates to the other stages in a water treatment process is important, as each stage of the process impacts on the process as a whole.


As well as the inputs changing, there can sometimes be a loss of knowledge of the treatment system, as knowledge is passed on from one operator to the next, often incompletely. This can lead to processes being used that are no longer fit for purpose, or processes being operated incorrectly.

Over time, the equipment and technology used in a wastewater treatment process needs to be reviewed and may need to be updated. Applying new technologies to a wastewater system does not always require significant investment, but could lead to environmental and economic gains for a business.



At Envireau Water, we understand that businesses want to operate their systems as economically and efficiently as possible. If you operate a wastewater treatment plant that might benefit from a review, get in touch with Eleanor on 01748 889 470, or email Eleanor@envireauwater.co.uk.

Changes to flood risk guidance in Wales

By Rachael Plant • April 30, 2025
Understanding both current and future flood risk in Wales is essential for helping planners, developers and landowners understand how flood risk is assessed within the planning process, ensuring that new developments are resilient and sustainable. Originally published in 2004, the Welsh Government recently published a significantly revised Technical Advice Note (TAN) 15 on 31st March, detailing critical changes to flood risk guidance. What are the key updates? Development types: The classification of development types has been updated and expanded. Categories now include Highly Vulnerable, Less Vulnerable, and Water-Compatible developments. Examples of Highly Vulnerable uses include all residential buildings, hospitals, schools, and emergency services infrastructure. This classification determines where development may be acceptable depending on the level of flood risk.

Recent Environment Agency Updates

By Rachael Plant • April 8, 2025
Since December 2024, the Environment Agency (EA) have released a series of flood and coastal erosion risk assessment updates, offering a clearer, more comprehensive picture of both current and future flood risk across England. What makes these updates so important? With approximately 6.3 million properties in England at risk of flooding and 3,500 properties at risk of coastal erosion by 2055, these updates are absolutely critical in order for you to protect and enhance your developments against the threat of climate change and extreme weather events. Whether a commercial or residential development, Envireau Water specialise in flood risk management and sustainable drainage solutions across the UK. By leveraging our technical expertise and deep knowledge of the UK regulatory system, we are known for achieving a positive outcome for even the most complex of challenges.

World Water Day 2025

By Rachael Plant • March 21, 2025
Climate change is an urgent issue we cannot ignore, and requires the collective action of communities across the globe if the worst effects are to be mitigated. From rising sea levels, extreme weather events to a loss of biodiversity, the potential impacts are widespread. However, this world water day, the focus is rightly on glacial preservation - our planet's largest natural freshwater reservoir. Why is it important? At Envireau Water, we recognise the widespread impact that glacial meltwater has across the whole planet, leading to the escalation of more extreme weather events as a result. Not only does this impact the environment with the disruption of ecosystems and water cycles, but also has a profound impact on society and industries reliant on a stable water supply. As a team of water scientists, we have witnessed first-hand the undeniable impact that flooding and drought events have had on the mineral, agricultural, industrial and development sectors, from failing crops and flooded farmland to a halt in distilling operations and delayed development projects, the ripple effects of these events are felt across communities and businesses alike.
