RA Dalton Success Stories
RA Dalton Ltd are the Klargester number one accredited installer covering the whole of the UK.
The Bioficient way forward.
In May 2019 our contracts manager Ian Murray attended a property in Patton, Kendal to carry out an inspection on a septic tank installed to serve the 4 bedroom property. Whilst on site we carried out dye tests due to the tank’s close proximity to the watercourse, although it was unlikely that this discharged directly to the watercourse we still recommended this was upgraded to a sewage treatment plant.
The discharge from the septic tank to soakaway was extremely slow and in the winter would prove problematic with poor ground porosity causing the drainage to back up. Our proposal was to utilise the existing inlet drainage, pipe through and infill the old septic tank and install a new package treatment plant below which would directly discharge to the watercourse.
The Kingspan Klargester Bioficient 1
The installation itself was a more tricky affair, with access issues into the garden making it next to impossible to get an adequate machine to install the tank we opted to install the new Kingspan Klargester BioFicient 1 from the neighbouring yard and utilising a larger 8 ton Excavator. The excavation work was done from the concrete pad on the other side of the hedge (this was required to be sufficiently trimmed prior to our start on site).
Due to the location of the installation an EA permit was also required, nearby to the property there was a known location for protected shellfish waters. This was another one of our main reasons for installing a new package treatment plant as the Kingspan Klargester Bioficient 1 would massively improve the effluent quality and limit any risks to the environment.
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.
