Risk Analysis

When inspecting manholes, it is important to consider health and safety issues. We are conscious of this and have therefore made a reputation of carrying out smooth manhole inspections in the Trethowel area. Back injuries and trapped fingers happen because old covers and frames rust and fuse together causing hinges to be unstable. By working with appropriate tools to lift the cover and holding the barrier in place, we prevent these injuries.

This is when we isolate the problem area, thus not allowing any form of external influence. We are well aware of the difficulties that accompany work in confined surfaces as well as the attendant psychological and physical hazards. Because of this, we ensure that all of our employees are conditioned appropriately.

Technology Is More Than Adequate

Manholes vary in size and shape, so working with a company like Drainage Cornwall, with the tools of the right size and specialty, is essential. The inspection equipment we have can assist in the delivery of excellent solutions irrespective of the conditions. Depending on our clients' needs, we have suitable tools for data reporting.

Our system of inspections is composed of distortion - free, high resolution digital cameras that have lenses with the capacity for wide angles. Our cameras take in the whole 360 view at once. This technology enables us to produce reports in a matter of minutes after completing an equally quick inspection of any shape or size.

Our Service Is Customer Oriented

A good part of Drainage Cornwall's advertising comes from word of mouth. All our customers are guaranteed 100% satisfaction. By the time we are through with the manhole inspection and clients confirm that our services are exactly what was promised, they are more than glad to spread the word about our reliable service at every chance.


We treat our consultation session with just as much care as the actual inspection. We offer advice based on feedback we get from you and then move forward with the best options. Whether it is a large or small project, our staff accord the same endearing patience and respect to every customer.
