Is Certified Training Needed In The UK Drainage Industry ?

There has been quite a bit of heated debate on several of the social media sites with regards to whether Certified Drain Camera Survey training courses are really necessary within the domestic drainage industry. As a drainage engineer myself and owner/developer of www.DrainDomain.Com I thought I would put down my thoughts on the subject

Through the DrainDomain.com website I am often asked to collapse02review drain inspection survey reports, this can be simply to provide a second opinion on the report findings or on occasions to help mediate between two parties in a dispute. I am also still active as a surveyor myself undertaking 300+ surveys last year with the following two anecdotes occurring in the last 18 months

Example One

A guy in the South East employs a local independent contractor to undertake a home buyers drain inspection on a property he is looking to purchase, the drain report comes back stating all is structurally sound but the system requires high pressure water jetting to remove deposits of grease and fat.

The chap then buys and moves into the property and within 6 weeks has a blockage, a second contractor attends site and tells the home owner he has problems as the system is constructed from Pitch Fibre pipe work and it requires renewal

I was then sent the original report and video files from the pre-purchase survey where you can clearly see that the pipe work between each chamber is indeed Pitch Fibre, the deposits of grease and fat reported by the original surveyor are internal blisters on the pipe wall stained with grease after numerous blockages

I know for a fact that the home owner took legal action on this matter and recouped both the survey costs and the costs of the necessary repairs on the basis that he was denied the opportunity to negotiate these costs off the original property sale price

Example Two

During the conversion of a large city centre building into a Hotel two developers went bust, both developers had employed two of the larger national drainage contractors to undertake full site mapping and charting exercises, both contractors had submitted differing reports on the condition and lay out of the combined drainage system

A third developer then took over the project and I was asked to re-survey and map out the system, the first thing we noticed was that the drainage beneath the foot print of the property was not cast iron pipe work as reported in the two earlier reports, it was our old friend Pitch Fibre

To be fair the Pitch Fibre was in very good condition as it was beneath the basement car-park and it only had rain water passing through it, the problem on this site was that this area was been converted into the hotel kitchen and the pipe work would be subject to large volumes of hot water and steam, the Pitch Fibre pipe work would not have lasted more than a couple years before it required renewal

These two examples are typical of what I see time after time from drainage firms of all sizes, if surveyors are getting the basics such as pipe construction, pipe size and drainage system layout wrong how can they be trusted to give accurate information on degrees of displacement to joints, fracturing and water tightness in general

All the above clients experienced and paid for a poor service which is never acceptable. As a contractor myself I would be just as concerned that there are surveyors out there who missed out on approximately 13k of drain lining repairs over the two sites

The UK Drainage Industry needs some set basic standards of training across all disciplines in order to raise the levels of service and to weed out the cowboy element

Sydney plagued by new breed of ‘super rats’ immune to poison

SYDNEY –

A new breed of “super rats” immune to poison and too smart to get caught in traps has invaded Sydney.

Dirtier than cockroaches and more voracious than mice, rats are set to become the city’s most-hated pest this winter. Because rats have been baited ever since they arrived in Australia with the First Fleet in 1788, they have now become impervious to most commercially available poisons.

And it gets worse — they are also canny enough to steal food from traditional snap traps without getting caught.

Australian Museum naturalist Martin Robinson said, “A lot of suburban rats have been baited for as long as Sydney has been settled, so many populations have become immune to those baits. One of the interesting things is that when they become immune to the bait, they can actually become addicted to it.”

So, how to defeat a legion of super smart rodents buzzing on an overdose of rodenticides? Bacon and fuse wire.

Robinson said bacon rind and other strong-smelling food sources like anchovies were perfect to lure a rat to a trap, while tying the bait down with fuse wire ensured the rodents did not get away without springing the catch.

Two species of rat inhabit Sydney homes — the ground-dwelling sewer rat and the roof rat, which as the name suggests is a much better climber and tends to nest in roof cavities.
