Why Choose a CCTV Survey?
- Inspection of newly constructed boreholes
- To illustrate the quality of work, verify construction records and to offer customer assurance
- Periodic inspection to determine the existing borehole/well condition and thereby propose refurbishment, remedial or preventative maintenance programs
- After service, the inspection verifies cleaning works and repairs as well as track and monitor well conditions and compliance.
- Pre-purchase inspection to establish the condition of a borehole or well at the transfer of ownership
- Groundwater monitoring
- Determine quality, geological strata, fissures and water producing zones
- Recover lost equipment by locating and facilitating the retrieval of lost equipment down the borehole.
- Sealing and abandonment of boreholes and wells in order to abandon a borehole it is vital to understand the construction details. Often these are not available in which case a CCTV survey can provide sufficient details to enable our engineers to provide site-specific proposals to meet Environment Agency requirements.
- Location and identification of obstructions. Before you can attempt to clear an obstruction you need to understand what it is and how it got there.
- Sand pumping. In certain circumstances the CCTV camera can be deployed into the borehole under pumping conditions to locate sand inflow and assist in any remedial works.
