Reader Question on Cesspool Cover Strength & Safety in the U.K.
I have been working for some time to add variations of wastewater treatment (and other InspectApedia topic) to our website and I'd welcome the opportunity to improve the UK-pertinence of our information.
Usually I find that the actual construction and operating principles are the same in most countries but that we use different terms that are unfamiliar across borders. (A water heater in the U.S. is a geyser elsewhere for example.) Other differences are in the details of building standards and codes. And of course when we conduct that research inevitably that allows us to add names of product and suppliers in the country of interest.
We do not offer for-pay consulting but we do provide pro-bono research and assistance for people of limited means. In addition, even if you were of - what should I say - more capable? - means I'd be glad to research specific questions that you may have. That work allows us to identify information that I'd want to add to InspectApedia anyway.
Are you looking for help specifically with a cesspool problem or is the topic more broad. Let me know what's up and I'll see how we can help.
In answer to your question, yes I do have a query that I wonder if you can answer, although may be a little unique?
I have an extra large cesspit serving 2 properties on my land (19m x 4m) and is a pit only no outlet . Its brick built and was installed early 70’s, it has 2 chambers running back to back, and has a concrete cover on it which spans the whole length and width of the tank having 2 cast iron lids for emptying in the middle.
As you can tell its quite robust and visually inside looks to be in good condition and is also maintained/emptied yearly with the emptying company stating it is in good order.
Question is – I inherited this with house from my Grandfather who used to drive over it with a small vehicle to get to his garage when the pit was still under a lawned area
Years later, with having to reduce size of garden meant the only way to get to the garage was to construct a crushed concrete/shingle driveway over the length of this cesspit.
I know my Grandfather used to drive over it periodically years ago, and before he had an extra bit of land to the side which he then used for the driveway, now this land has been removed and hence the above having to happen , I am driving over it but a little worried knowing the size of it could swallow 2 small cars! However it does have a 6” thick concrete lid spanning the length of it and then additionally covered with crushed concrete and shingle making this cover about 12” thick now ….
Could you please advise if you would consider that this was the type of cess that was constructed for driving over, and would still be ok??? - L.H. 3/25/2014
Reply: warnings about driving over the cesspool
Watch out: driving over a cesspool risks sudden collapse and even a possible death or injury.
