Biosolids Management | Welsh Water

Discover how our Biosolids Management System (BIO) helps UK water companies streamline operations, ensure regulatory compliance, and achieve full traceability from treatment plants to farmland. Trusted by national regulators across the UK and Europe, BIO provides a flexible, end-to-end solution that simplifies reporting, automates workflows, and modernises biosolids management.

Modernising Biosolids Regulation & Workflow

A complete bio‑solids management platform was deployed for Dŵr Cymru Welsh Water, replacing fragmented legacy processes with an end-to-end solution that tracks sludge from treatment plants to agricultural land using the Tracsis BIO platform.

Automated Regulatory Adherence

Our BIO solution supports compliance with UK regulations including Environment Agency standards, the Safe Sludge Matrix, BAS and nitrate management requirements, reducing risk and ensuring adherence across all stages of biosolids handling.

Full Lifecycle Traceability

The platform captures biosolids movements from treatment works through to field application, automates soil sample results, and provides documentation tracking. This gave Welsh Water full visibility over operations and reduced manual administration.

Connected Systems & Data Flows

Our custom-built BIO platform connects seamlessly with JRP weighbridges and multiple data sources, delivering precise, real-time tracking of treatment centre operations and deliveries. It also automates reporting, stockpile inspections, and delivery documentation, reducing manual tasks while enhancing operational transparency.

About Welsh Water

Dŵr Cymru Welsh Water is a not-for-profit company which supplies drinking water and wastewater services to most of Wales and parts of western England that border Wales.

In total, it serves around 1.4 million households and businesses and around three million people – and supplies nearly 830 million litres of drinking water per day.

It is regulated under the Water Industry Act 1991 as amended by the Water Act 2014.

What are Biosolids?

Biosolids are the residual material left over from sewage treatment processes, and can be spread on land as a fertiliser for agriculture.

Biosolids can contain heavy metals, pathogens and other harmful compounds so their use is strongly regulated by the Environment Agency.

Tracsis Geo Intelligence has worked with several water authorities to develop a cloud based tool to replace mainframe application and monitor the journey of biosolids from the time they leave the treatment plant to spreading on farm land.

How Local Authorities Can Ensure Safe and Compliant Biosolids Use on Land

Project Requirements for Welsh Water

Welsh Water required a fully integrated biosolids management solution that could operate seamlessly within their existing business and technical environments.

As part of a wider Sampling Analysis Management (SAMs) programme to replace the legacy Quality Database System (QDB), a detailed market review identified that only a specialised biosolids management platform could meet Welsh Water’s operational and compliance requirements.

Over 3.5 million tonnes of biosolids are produced in the UK each year

With the majority recycled to farmland, accurate tracking and compliance is more critical than ever.

Biosolids Assurance Scheme (BAS)
The Nitrate Regulations
Nutrient Management Matrix

System Features

Solution Benefits

Soil sample results on request & automated soil sample results updated in BIO.
Monitor the journey of biosolids from the time they leave the treatment plant to the time they are spread on farmland.
Manage the documentation for all biosolids disposals accomplished.
Manage the documentation produced at the end of the process and sent to the farmer.
