The Twelve Days of Christmas With Hydro Cleansing | 2. Case Study NPL

“On the second day of Christmas,
my true love sent to me,
two feet of tree roots,
and Hydro Cleansing’s Mega-Heat…”

Continuing our twelve day countdown to Christmas, today’s blog is a nice juicy case study! However, this isn’t just any case study, this case study features blocked culverts, four foot long tree roots, over 50 TONNES of silt, and of course, an expert team of Hydro Cleansing engineers getting the job done. 

Back in the Summer we were called out to deal with some blocked culverts, syphons and silt traps by the NPL. On our arrival it was clear that there was something seriously big blocking the syphon under the railway, even our camera couldn’t travel underneath to get a clear picture. Upon further investigation the engineers discovered that the blockage was clusters of tree roots growing through the tunnels. Check out the full scope of works below!

Client – National Physical Laboratories | Kings River Outfall Desilting

Scope of Works – Desilting of culvert | Root cutting in syphon under railway | Desilting of silt traps

  1. The culvert in Normansfield Road had a high level of silt and elevated water level, the camera was then unable to return a picture of the internal condition of the pipe. We needed to remove this silt and reduce the flow during the survey, we then proposed to undertake this with a super combination unit taking one day to complete and resurvey.
  1. The syphon under the rail way had root ingress which prevented the passage of the camera, to remove this we needed to reduce the flow through the culvert and use high pressure root cutting with specialist root cutting nozzles suitable for large bore pipes. We took one day to complete and resurvey.
  1. The silt traps in five manholes needed de-silting, they contained an average of 1m of silt each. The silt traps are 2.5m in diameter which will yield approximately nine tonnes each. We took two days to complete.

Don’t Let A Flood Ruin Your Festive Cheer!

Hydro Cleansing Will Support You Through the Flooding Season.

Following Storm Angus, Wales and the South of England are currently being battered by high winds and even higher levels of rain fall, and as your Mother would say; prevention is better than cure! If that doesn’t inspire you to get outside and start checking your culverts and clearing your drains, then take a look at some of our flood work from previous years.

Clearing a Culvert Under the A3 Highway:

Here are some of our engineers clearing a culvert beneath the A3 on behalf of a local council. Our expert engineers were down there, in full confined space PPE to cut through the build up of silt with high pressure jets, and of course Megatron, which was on site to suck the waste away for disposal at an impressive 6000 cubic feet per minute. Megatron’s state of the art liquid ring pump creates a vacuum within the bulk tanker in order to efficiently fill it with waste, and also allows a second bulk to replace it while it disposing of the waste. This meant that the work could be continuous and we didn’t have to deploy extra vehicles which allowed us to get the job done quickly.

Flood Response at a Nursing Home in Bristol:

Saving your granny is all in a days work for our teams, or at least back in June it was. We sent out our specialist engineers in a combination vacuum tanker unit to help out a nursing home near Bristol, where the flood waters were about to reach the property. The power of our tanker meant our team could remove the water from the flooded garden area and front of the property where the flood was disrupting traffic and scaring pensioners. Job done!
