Oneline successfully clean tank 3 SBR at Weymouth STW

Oneline successfully won the tender for a tank cleaning project at Weymouth Sewage Treatment Works.
 
All work to be undertaken was underground, and with a tank size of approx. 60m x 25m x 9m deep, the method of work, safety plan and equipment all had to be carefully thought through.

Once the client had emptied the tank to a depth of 400 – 500mm, the task was to remove sludge and rag that had built up over a number of years. Oneline used one of their recycling units and their deep suction tanker to suck out liquid and rag/grit. Once they had separated out the rag, the liquid was decanted back into the works, and the rag/grit was transported to Avonmouth STW for recycling.
 
To complete the project efficiently and on time, Oneline had 6-8 people on site working in shifts of approximately one hour in the tank.
 
Oneline used specialist equipment such as two Davit lifting devices, extra gas monitors, extra escape kits and additional air movers.

Because Oneline were successful with the outcome of the works, we will be invited to tender for the works to clean out the next SBR tank requiring attention.

CCTV Drainage Surveys Prior to Property Extentions

If you are thinking of extending your property, designing a new development, or building a garage or conservatory, you will need to consider whether there is a public sewer in the way.

Work of this type may require a camera survey or sewer diversion, and Wessex have some very useful information on the process and outline some important steps in their 'Guidance notes for CCTV Camera Surveys' document: https://www.wessexwater.co.uk/Developers/Sewerage/Building-near-sewers/

One of the first steps they advise is to obtain a CCTV survey. As you will see in the Wessex Water CCTV Camera Survey Guidance notes, Oneline Surveys Ltd are an approved Wessex Water contractor. We hold Wessex Water Permit Cards and we have been confirmed as holding all necessary qualifications and accreditations. We are therefore approved to work on Wessex Water drainage and create CCTV survey reports to their requirements.

Please don't hesitate to call us if you would like us to quote for your drainage survey.
