Update: Groundwater monitoring borehole install in New Pond Parade car park – postponed

What we are doing

UPDATE: We planned to carry out these works from 20 to 25 January 2025. They are now postponed, the new dates to be confirmed in due course.

In order to support the construction of the new HS2 tunnels, we need to carry out groundwater monitoring along the line of route.

Two new groundwater monitoring boreholes will be drilled in the New Pond Parade and West Ruislip Station car parks. The boreholes will be located in between parking spaces so we can routinely access them to take regular readings.

New Pond Parade car park

We will be suspending seven parking bays during these works, the car parks will remain open during these works.

We will erect hoarding and noise reducing screens around a drilling rig. Drilling the borehole should take around five days to complete. We will use borehole drilling equipment to remove existing ground and backfill material. These works will be noisy, and we will place acoustic barriers around our works to limit noise and dust. Once the borehole is complete, we will install a secure cover. We will monitor the works closely to ensure we operate within approved noise and vibration limits.

We would like to apologise in advance for the disruption or inconvenience this may cause.
