Darwin Group Threatening Letters to Reconnect Drainage Pipe to Septic Tank

Firstly I'm attaching part of a report done when SMC enlarged the original Parry's Yard in 2008 which states that the existing yard area drains to the south-west corner - we are east of the yard.

Now I'll attach a page from a design and access statement submitted by Built-Off Site (now renamed Darwin Group) for their first pond planning application.

Now I'm attaching letters sent by Built-Off Site to us after I had to smash the pipe which led only to our septic tank, and my replies.







The above letter was sent to my mother (using the wrong name), and not me. My reply was as follows:-

Dear Sirs,

We are in receipt of your letter of 16th November 2009 regarding the yard drainage system. Firstly my mothers name is not ... and secondly as the property is jointly owned any further correspondence should be addressed to myself.

The yard drainage system has not been functioning correctly for at least two years. All of the water from the yard drains into the Forestry Commission ditch at the rear of Shropshire Mini Mix’s land. This is evidenced by the positioning of the oil interceptor on SMC’s land. The Forestry Commission confirmed earlier this year that there is a blockage near the main road stopping their land from draining and therefore the yard from draining.

Since February the yard has not even been connected to this ditch because of a fallen tree and a build up of dirt behind it. I checked this a month ago and no action had been taken to remedy this situation, merely a pit dug at the back of the yard, presumably by SMC.

The ditch north of us has not been flowing for many years, meaning yard water could not exit the yard our way, and yet our orchard has never flooded, which would have been the case if your surface water flowed our way. The flooding only started early this year when we know the yard effectively stopped draining. After we severed the connection to our septic tank, which clearly couldn’t function because of the water flooding into it, this water forced its way out of the manhole above ground. We had no option but to stop what was filthy contaminated water flowing into our orchard and my horses field.

We took every step available to us to check for any connection from the manhole to the ditch on our property. SP Holding were adamant that there was no connection; the pipe which is approx 2 feet down in the manhole was connected only from our septic tank directly into the manhole, with the waste water intended to flow through the interceptor. We employed a drainage contractor to dig out our ditch to double check for any such connection and did not find one. Because the pipe in the ditch is approx. 3 feet down any connection would have had to have been from this pipe.

Furthermore the opinion of the drainage contractor and two other people was that our manhole contained diesel as well as filthy yard water. All of this should have been going through the oil interceptor. As I explained to you our land contains the former vehicle wash. The manhole on our land was designed to take the waste water from this wash across the yard to the interceptor.


My Uncle, who was a director of the company which installed the drainage system, then came from Towyn to look at the drainage system. As he stated to someone at Built Off-Site he believes our manhole is directly connected to your manhole in front of the office. In his opinion your gully is ‘teed’ into this drainage pipe, hence it is not draining because this pipe is permanently full of water. You do not mention whether any attempt has been made to check whether this is the case, despite the very dry summer making it easy to check this connection.

The drainage pipe from our manhole therefore goes to your manhole in front of the office, around the back of the workshop and on to the oil interceptor and the Forestry ditch. As already stated this drainage system is designed to ensure all surface water goes through the oil interceptor.

As the drainage contractor and my uncle explained, this land is very flat, there is very little fall on it, which is why the water was backflowing onto our land rather than pooling above ground.

There can be no dispute that the manhole on your land does not drain our way because otherwise all of the yard drainage would come our way, which it clearly does not. Therefore I am amazed that you are purely targeting us regarding the failure of the yard drainage system instead of contacting the Forestry Commission and SMC to get the water flowing from this yard. All of the drains and gullies are full of mud and silt which has built up since the drainage stopped flowing freely, and no attempt has been made to remedy this situation.

Clearly the priority here is to sort out the yard drainage system. We will not have our land contaminated and the ditches polluted by yard runoff including diesel and cement coming through your land from the rest of the yard simply because it is the easiest way to remedy your situation.

Regarding the willow tree we can find no evidence of any ‘lifting’ of the tarmac on your ground from any tree roots. I would suggest though that you firstly look at the extremely large tree stump from the tree near to it which was removed around five years ago, and whose roots will now be dying back.

It is also possible that any crazing is being caused by water forcing its way around the drainage pipe and displacing the ground around the pipe. This was the situation we found when we tried to stop the water entering our manhole while it was pumped out; it was impossible because water was flooding in around the pipe.


Yours faithfully,

Built-Off Sites second letter:-




Again I responded:-

In response to your letter you do not deny that the manhole on your property into which the gully in front of the workshop feeds and also your far gully drain into the Forestry ditch on the far side of SMC’s land. This drainage system is not functioning correctly. Because the disputed gully is connected to this manhole, and indeed only around 10 feet from it, you cannot disclaim responsibility for water backflowing into our manhole.

You are jointly responsible with other companies in this yard for the maintenance of this system. It cannot be denied that there is no visible outlet pipe from this yard. If it is still intact it is at least two feet under water, and has been for at least twelve months. There is no connection to the Forestry Commission ditch itself. A pit has been dug into which water covered with a layer of scum is trickling, at ground level, under a fallen tree into the ditch. I have enclosed photographs taken in September showing the pit full of water which is this yards drainage system. Nothing has changed, I checked this morning.

Our agricultural contractor, his employee, and two other people are positive that there was diesel in our manhole. What you are suggesting is that we allow the illegal discharge of oil and diesel to a water course on a daily basis, because your drainage pipe, to which your gully is connected, also takes all waste water from the workshop, new wash area, and from the drive area which contains silt and cement.

In the summer you told me that our willow tree was stopping your gully from working. I pointed out that the yard drainage system had not been working for a substantial amount of time and your gully was not working because it is at the furthest point of this sewer, and that because we had severed the connection to our manhole your gully was not now backflowing onto our land. Your gully was at this stage underwater.... opened the manhole in my presence and found it to be absolutely full of dirty water.

We then proceeded to R.A. Allmarks land and checked his gully. Looking down it you yourself stated that the water level should not be directly under the grid. As evidenced by my photographs water can only leave this yard through pushing under pressure into the wood, it is not flowing freely.

Reinstating the pipe which we disconnected will not connect your gully to the ditch, because if the water had been backflowing to the ditch we would not have needed to disconnect it. As already stated, this water was not going into the ditch but directly underground to our septic tank. When the pipe was disconnected one month later due to surface flooding our contractor informed me that the water in this pipe was black. This is clearly therefore not just water from your gully.

I have again spoken to my uncle regarding the yard drainage system and have also spoken to J & H Parry & Sons’ former Contracts Manager, who is a Chartered Engineer (Ceng MICE). Both have confirmed that the drainage pipe into which your gully feeds takes all of the surface water to the Forestry Commission ditch via SMC’s land. No water from the yard has historically entered the ditch on our land.

Both state that the drainage system is virtually flat, which has given problems in the past and means that the system needs constant maintenance, which it is not now receiving.

They both explained to me that there has always been a problem because the Forestry Commission ditch is too shallow and because of this when the system was put in it was put in with hardly any fall; the further from the ditch the drainage system is the flatter the drains are. Your gully and our manhole are at the flattest end of this pipe. This has been the case for over forty years.

The Engineer we have consulted has also told me that slow drainage around the gully is not unusual because of the problems with the falls on the drains – he was employed by Parry’s for around 20 years and reiterated that that is why constant maintenance of the drainage system is essential.

Because of the flatness of the drainage system the water will therefore easily flow our way if there is a blockage upstream.

What you are suggesting is that when the yard was built a drainage pipe was installed which drained both ways, which is not the case. It was designed to take all surface water to the ditch at the far side of the yard precisely because of concerns about pollution from the wash and the workshop, which could have led to a prosecution if contamination to the water course occurred. This is why the oil interceptor was installed at the far side of the yard.

Our ground has been completely undermined by the volume of water forcing its way out onto our land and onto my grandmothers land, all of which is very much lower than the yard.

I have been advised to seek legal advice regarding the damage to our property from the severe flooding which we experienced due to the water from the yard backflowing onto our property. I am also going to consult with my grandmother about joint action against the occupiers of this yard for negligently failing to take action to ensure the correct functioning of this drainage system.

The gully outside my grandmothers property feeds through the field into the main drain. Because of the failure of this system my grandmother has experienced severe flooding to her property, including her garden and lawn area, resulting in her son-in-law having to erect a bund to prevent the water flowing up her drive to her back door. Water from this gully has to be able to enter the main drain – it cannot do so if the main drain is not emptying as designed into the Forestry ditch.

It cannot have escaped anyones notice that my grandmothers land has been flooding since before January 2007. SMC were themselves told in 2006 that they had infilled over the outlet pipe. In May 2009 I emailed the attached letter (I have not printed the latter part because it is not relevant to this issue) to SMC and copied it to your email address. (email removed) clearly stating the problems with the drainage system. We received no response regarding the drainage issues, merely a response from SMC regarding the borehole.

I have also been advised to obtain details of your septic tank and whether there is any connection to the drainage system from this septic tank. I would therefore be obliged if you would forward a plan showing the system and the soakaway. If necessary we will be requesting that our solicitor formally requests this information.

In conclusion when you fulfil your obligation to ensure your runoff can flow freely to the Forestry ditch, as it is designed to do, and the drainage system is emptied and cleaned out, we can then see if your gully drains.

If you are not prepared to take any steps to fulfil your obligations in this matter then be assured that we are prepared to go to Court .

Yours sincerely,

After failing to get us to re-instate the pipe to our septic tank, or check the drainage, Built-Off Site then decided to put a 'wildlife' pond in north of our land.  A planning application for this had to be withdrawn because although the pond was supposed to be fed only by rain water, they had connected the industrial estate drainage system to it and hidden the pipes.  When photographs were submitted showing this  a new application for an attenuation pond was submitted.  

Getting this withdrawn was a long haul taking 2 years and Built-Off Site AGAIN  stated they were taking legal action over our smashed pipe.

This is from the Ombudsmans report of February 2012:-


So here we have a claim by Darwin Group that they have conducted a drainage survey, but no-one asked to survey our land so how was that possible?

Note also that they they never disclosed this survey to the Council or ourselves.

Next we had a letter from their solicitor.




Our solicitor replied:-

Dear Sirs

OUR CLIENT: GAIL PARRY
YOUR CLIENT: BUILT OFFSITE LIMITED

Further to our letter of 14 July 2011, we are now in a position to respond substantively to your letter to our client of 27 June 2011.

We note that your client’s claim that they have experienced flooding to their land, particularly during heavy period of rain, and that this has caused significant inconvenience and disruption to their business. Our client is not aware that your client’s land has previously flooded and we would therefore be grateful if you could please provide evidence of flooding and further details as to the inconvenience and disruption this has caused.

We further note that your client has had a drainage survey carried out which they claim confirmed that the problems experienced by your client in relation to flooding has been as a result of a drain being “blocked off” or damaged at a point where it crosses our client’s land. However, you have not produced a copy of that survey, which makes it difficult for us to assess the position fully. We would be grateful if this could be provided as a matter of urgency.

As regards the drainage rights contained in the titles to our clients’ respective properties, these are clearly very vague and refer to those rights which have been in existence at the time the transfer was made in 1974. There is no mention of what rights have previously been enjoyed and in what direction any right of drainage would go.

You have referred to witness statements which will confirm that the drainage system across our client’s land has been in existence for in excess of 20 years. Please provide these statements. Our client does not consider that any witnesses will be able to confirm that the drainage from your client’s property has been over our client’s land, as this has simply never been the case. The direction of the drainage from your client’s land has always been away from our client’s property in a south westerly direction through the industrial estate into the Forestry Commission ditch, a ditch system shown on the Ordnance Survey map.

It is our client’s position that any problems with the drainage system are as a result of blockages, possibly by concrete, further along the drainage system at the other end of the business park. The direction the drainage flows is away from our client’s property to the south west, as evidenced by the positioning of an oil interceptor in the south west corner of the industrial estate to ensure oil, diesel and sewage did not enter the ditch network.

The drainage does not and has never flowed across our client’s land. The pipework situated beneath our client’s land is simply incapable of coping with drainage from the business park if this were to take the direction suggested. The reason why it cannot cope is because it was never intended, and has never been the case, that the flow of drainage would be across our client’s property. There is a manhole situated in our client’s garden and it can clearly be seen if the manhole is open that the pipe from this junction towards our client’s septic tank is higher than the pipe leading to it from your client’s property. This clearly suggests that the flow of the drainage is away from our client’s property, not towards it.

Our client was required to take action to disable the pipework as there was potential for serious damage to be caused to our client’s land as a result of the blockages further along the drainage system. This could have caused a backflow of polluted water which would have a devastating impact if this overflowed onto our client’s land.

We therefore do not consider that your client has any claim against our client when it is clear that polluted water from your client’s site does not drain across our client’s property. Should your client continue to assert that there is a right of drainage over our client’s property, then we would suggest that the appropriate way of dealing with the matter would be for a formal drainage survey to be carried out to establish the direction of the drainage flow and what the causes of any problems in the drainage system are.

We would be grateful if you could confirm that your client would be prepared to allow access to their site (our client will provide seven days’ notice) for a drainage surveyor to carry out a survey.

We look forward to hearing from you.

Yours faithfully

Despite two letters we received no reply from their solicitor. 

We have still not had a copy of the drainage report.  

This was the last we heard about the matter until the letter of 2015 from Shawbury Industrial Estate Management which was signed by a Director of Built-Off Site when AGAIN they stated they would be revisiting the matter.

Clearly what we have here is out and out bullying.  I mentioned this matter to a police officer who was at our house because of an incident outside our property, and when I said to him that they would not resolve the issue he stated: 'well, they won't will they'.

The problem for Darwin Group is that although we smashed the pipe, we smashed it at the dividing fence line between our land and theirs.  The manhole this pipe feeds into is intact as is the pipe which goes OVER the ditch.  We actually exposed this pipe and left it exposed for over six months but no-one wanted to check it.

This is the pipe


Again I will attach  photographs showing what Darwin Group want to do to our land.




I think it's pretty obvious that if there had been a pipe connection to the ditch our land wouldn't have looked like this, would it?
