Septic Tanks Replacement


Weegaz

Recommended Posts

Hi,

 

Is there a regulation somewhere regarding septic tanks and when they should be replaced. ie after 30 years etc.

 

We will be running a pipe from our new build past my mother in laws septic tank and she was saying it in nearly 35 years and that she would replace it when we where digging if she needed to.

 

It is still working ok and she has got it cleaned every year.  Its more the fact that we will have digger in and she would do it now rather than say 5 years if the regs said that was limit.

Most likely  the leach field is shot by now - 10 years and they start to become inefficient. When you say you are digging past are you sure you aren't hitting the leach field..?

 

Is there any reason you couldn't put a shared system in..? reduce the cost for both of you effectively..?

There is generally no legal need to update them, unless some polution event occurs. A house near here was ordered to replace his septic tank with a treatment plant.  On a new build now you would be mad to even try to get away with a septic tank, we would never have been allowed to discharge to the burn with a ST.

 

A shared treatment plant might be the logical solution here if your building control will accept it. You will obviously be installing one, so the extra cost to install a bigger one is probably not that much more

We are putting a full treatment works tank in, we are running a drain approx 150m from our house past her septic tank to allow drainage of our surrounding garden.

 

I would want to keep the 2nr houses on separate systems to be honest.  But i will discuss this with the family.

 

We thought if she was to update her tank to a water treatment tank then we to 'T' into the outlet when running our drain past it.  She was looking to increase her garden size also which includes the area around current septic tank as our driveway eats into her garden at the other side.

AFAIK you cannot fit them anymore anyway - any new TP needs a certificate or approval from the EA in England and Wales
