Dye Tests, watercourse discharges and the Bioficient 1.
Earlier this year in July we received an enquiry from a customer who was looking to have a sewage treatment plant installed to serve their home. They were located in a small village near Thirsk where none of the properties were connected to mains sewer and all of them had septic tanks or sewage treatment plants.
Unfortunately for this customer in particular certain shortcuts had been made during the initial build of the property and the waste was discharging into a field drain which had been installed to deal with the water from the highways and flowed straight to the nearby beck.
The customer carried out multiple tests themselves including dye tests to determine the discharge location. This was invaluable information for us to provide a quotation as the more detail that can be provided in the earlier the stages the more accurate we can be in our scope of works.
Dye tests and invaluable information.
Access was not the easiest on this site in particular as all the machinery was required to be tracked between two properties, this predicament meant there was a requirement for another machine on site located at the front of the property to load concrete into the dumper and to load a trailer to move spoil off site.
The system we proposed to install to the rear of the property was a Kingspan Klargester Bioficient 1 package sewage treatment plant, due to the site limitations and installation location the shallower construct of the Bioficient was best suited in comparison to the deeper install BioTec or BioDisc.
The low profile lid on the Bioficient also proved preferable for the customer as there was less visual effect on the garden.
The Kingspan Klargester Bioficient 1 Sewage treatment plant.
The Bioficient 1 was installed with the accompanying required inlet and outlet pipework, as the system held the BSEN 12566-3 certification the treated effluent was able to discharge directly the watercourse.
Following the installation of the Sewage treatment plant we always recommend that the manufacturer’s recommendations for a maintenance contract is complied with, for this system in particular annual servicing is the best way to keep the system running efficiently and to ensure that the EA requirements are adhered to.
RA Dalton Opens New Rookhope Office

County Durham wastewater specialist RA Dalton has relocated members of its finance and accounts team to a new office at Unit 1, Rookhope Business Centre.
The move sees Accounts Manager Katie Jackson and her colleagues take up residence in the dedicated office space as the family-run company continues to expand its workforce and nationwide operations.
The Rookhope premises provide valuable additional space for the growing department while keeping the team in the heart of Weardale, close to RA Dalton’s Cowshill head office.
From a local family business to a national employer
Founded in 2003, RA Dalton has grown from a small local family business into a nationwide employer with more than 100 staff across the UK.
The company supplies, installs, services and maintains sewage treatment plants, septic tanks, pump stations and other off-mains drainage systems, working with homeowners, businesses, developers and organisations throughout the UK; providing support at every stage of the wastewater process.
Supporting a growing nationwide business
RA Dalton’s finance and accounts team play a vital role in supporting the company’s day-to-day activities across the UK. As the company has grown, so too has the volume and complexity of the work carried out behind the scenes.
The new office creates a dedicated working environment for the team. Colleagues can collaborate closely and continue to deliver an efficient service to customers, suppliers and other departments across the business.
The finance department continues to grow from strength to strength. RA Dalton recently recruited a new Accounts Receivable Coordinator, who joins the team at its new Rookhope base. This latest appointment is another key part of the company’s wider strategy to strengthen its internal operations and ensure it has the people and systems that support continued development.
Continued investment in Weardale
While RA Dalton now works with domestic and commercial customers across the UK, the company has retained strong links to Weardale. The decision to establish the finance team in Rookhope allows the business to create additional space without moving this important function away from the local area.
The new office demonstrates RA Dalton’s continued commitment to County Durham and the rural communities surrounding its original Cowshill headquarters, while bringing new professional employment opportunities to rural County Durham. This will help people build their careers without needing to travel to one of the region’s larger towns or cities.
RA Dalton has continued to invest in its people, premises, equipment and services as demand has increased. The new Rookhope office is the latest stage in that growth: providing Katie and the wider team space to support the business as it moves forward.
The finance team’s new address is Unit 1, Rookhope Business Centre, Rookhope, Bishop Auckland, County Durham, DL13 2DA.
