New computer system aids biosolid disposal

A new computerised mapping and recording system should help water companies and waste management contractors to meet their legal obligations when spreading biosolids on land.


Designed for practical management of biosolid applications, ‘Enhance’ uses a central, office-based recording system combined with a computerised set of Ordnance Survey maps showing fields and records of biosolid applications. When an individual field is selected, for example, the system reveals what has been applied in the past and where it came from, along with how much can be applied now. Details such as soil analysis records, the location of the nearest treatment works and access points to fields can also be displayed.

The mapping system will also automatically highlight any areas that cannot be treated, such as groundwater protection zones, or watercourse and footpath restrictions.

Records are held on a central computer server, which is updated every time a user links-in, so that if a laboratory reports a change in biosolid source for a particular application, the records and reports to farmers receiving the products will be automatically adjusted. The system also continuously updates information on full legislative audit requirements.

“The water industry has to be able to clearly demonstrate that it is meeting its obligations and regulations when recycling biosolids to land,” said Alexander Maddan, Managing Director of waste management specialists Agrivert, the company marketing Enhance. The system can also bring improvements in operational efficiency and customer service, says Maddan. “With the improved communication through Enhance it’s easier to get the right thing, in the right place, at the right time,” he said. “It also provides a better level of information and advice to the farmer customers. It’s a far more professional approach that can add-value to biosolids and gives farmers the confidence they are meeting farm assurance standards.”
