Customer Testimonials

John organised applying for permission to connect the foul in the road and liaised with the utility companies for ducting. This was our first building project as self-builders of this size and he advised us throughout the project and helped it to run smoothly even with unforeseen water and drainage problems. The project stayed on schedule and on budget. John and Mark’s expertise were priceless.

FAQ's - Section 1

With so many variables involved here it is difficult to give an average cost, but anything from a few thousand pounds to tens of thousands. Click here for a quote.

A sewer connection in the Highway can take as little as a few days, up to a week or more or sometimes many weeks in the event that the public sewer is a long way from the site.

Beware though – the paperwork in advance will take much, much longer. You will need to do a , which we will normally take care of for you. In the event that the public sewer is in the Highway (90% of the time) we will need to apply to the local Highways Dept at the County Council for a , ordinarily you cannot do this yourself, we have to do it for you. This process cannot normally be started until you/we have the from the water authority - Highways need to know that the Water Authority are in agreement that the connection be made.

The application will normally take anything from a few weeks to a couple of months. Once we are in receipt of the , we have to give notice to Highways that we want to use it. For a very small job in the Highway, the notice period is 1 week. For a week’s work in the Highway, the notice we have to give is often 3 weeks, and 3 months or more for a major project.

An increasing amount of jobs in the Highway require a road closure, and the minimum legal notice period for one of these is 3 months. And just because we give notice to Highways that we wish to use our licence, we won’t necessarily get permission to do so. There has to be no other roadworks going on within a certain radius of the site, and in some instances other contractors could have booked ‘road space’ in the surrounding area for the next few months or more, meaning you’ll be asked to join the back of the queue. In some areas you cannot work during school term time, you’ll have to wait for the next school holiday – as long as other contractors do not already have ‘road space’ booked for then. So all in all:

Time required to get a to connect to a public sewer                 3-6 weeks.

Then… Time required to get a to ‘dig up the road’                      3-10 weeks.

Then… Notice period to be able to use a Section 50 Licence                         1-12 weeks.

Then… Time taken to do the work                                                                              (normally) 3 – 10 days.

Total of anything between 8 and 30 weeks. In the event that you need a sewer connection doing please contact us as soon as possible. You’ll be surprised how many people build a house and then ask us to start the sewer connection process, whereas this process needs starting ideally when the build starts.

Public (adopted) sewers in the Highway can be as shallow as 1m deep, but tend to average 1.6m – 3m deep, but with some a lot deeper. It is not uncommon or some very old public sewers to be 6m deep, or more.

The depths of a lot of public sewers are documented by the various water authorities, as are the exact location of them. However, a lot of public sewers are still not mapped.

It depends. In the case of one house or a couple of houses then connection by ‘junction insertion’ or ‘saddle connection’ would be a more common method of connection, unless of course a manhole exists in close proximity.

In the case of a larger development of more than 3 houses, a connection into a manhole is normally required, or construction of a new manhole on top of the existing pipe if one does not exist close by. The method of connection will always be dictated by the relevant Water Authority, and will always be detailed on the ‘Section 106 Approval Letter’. When instructing JW Clark to undertake a sewer connection, our service will normally include facilitating the Section 106 application , unless you have already done it or wish to do it yourself.

Junction Insertion

“Oblique junction insertion fitted onto a public sewer, the pipes either side of the sewer are old and new water mains”.

A junction insertion is simply a ‘Y junction’. We cut out a small section of the existing sewer and fit a junction insertion. It sounds simple, but of course there’s a lot more to it than that! The ‘flow’ will normally have to be stopped ‘upstream’ in the next manhole for the work to be carried out safely. A junction insertion will normally be the preferred method of connection onto a public sewer that is up to 300mm in diameter.

Saddle Connection

A saddle connection is the preferred method of connecting onto public sewer greater than 300mm in diameter, and is more likely to be used on a surface water connection than a foul connection – as foul sewer pipes above 300mm are not so common, whereas surface water sewers are often 300mm in diameter, or more. This method of connection requires a hole to be professionally core-drilled into the existing sewer pipe, normally towards the top of the pipe on the side, and the ‘saddle’ to be fixed onto the pipe by way of fast-setting cement slurry or resin. Further pipework can be connected onto the saddle once the connection has cured.

Victorian brick culvert

A saddle connection is also the preferred method of connection into a Victorian Brick Culvert. In this instance a proportion of the culvert on the outside will normally be carefully excavated around first, and a concrete ‘jacket’ carefully applied to the brickwork. When this has cured, the concrete and the brickwork are drilled together. The concrete jacket is required as the brick culvert is dependent on the brickwork for its strength, and core-drilling without the concrete jacked having first been applied would compromise the integrity of the culvert.

In relation to sewer connections, a Section 106 application is required to connect a property to the public (adopted) sewer for the first time. (Not to be confused with a ‘Planning’ Section 106 Agreement, these are private agreements made between local authorities and developers).

How to apply for a Section 106.

JW Clark can apply for a Section 106 on your behalf, and we normally do so for most customers, however if you want to do it yourself then that’s fine.

You/we will need the following to be able to apply for a Section 106:

  1. Drainage Plan – This needs to show foul pipes and manholes within the site, the connection to the public sewer, whether it be by or  and it needs to show the existing public sewer in the Highway or otherwise. A drainage plan previously put together for a ‘new build’ property will normally cover the foul system in the site, but will rarely detail the sewer connection, nor the existing public sewer. It will need amending to include these to be suitable for the Section 106 application, and this is best done by the same architect who drew the original drawing. The drainage plan must also detail surface water/rainwater pipes and manholes in the site, and the method by which it is being discharged, i.e. soakaways or rainwater harvesting system etc.  .
  1. Site Plan.
    This will detail the boundary of the property and must show the property in relation to neighbouring properties or nearby landmarks.
     
  2. Consent/Signature of Apparatus owner.
    Although we will take care of the Section 106 application for you, you will normally need to sign as the ‘Apparatus Owner’ - Although the connection to the public sewer will always be adopted by the water authority, the pipework in the Highway leading away from the connection (the lateral) will normally remain the property and the responsibility of the property owner (unless the lateral is being adopted ). Apart from this one signature, we can normally take care of the Section 106 application for you, and we will normally include to do so in our quote. For a quote click here.
     
  3. Fee to the water authority .
    The fee for a Section 106 can vary between water authorities and is sometimes dependent on the type of connection. Prices start at about £400, and the exact price will always be detailed by us in our quote to you.
     
  4. Method Statement & Risk Assessments.
    We will always put together a Method Statement and Risk Assessments for any sewer connection that we undertake and these must be supplied to and approved by the relevant water authority before work can commence, and will normally have to be included in the initial Section 106 application. ‘Generic’ Method Statements and Risk Assessments are not permitted, they must be ‘Specific’. Our quote to you will always include for these.

Most water authorities charge upwards of £400 for a Section 106 application, and the fee will have to be paid up front before the application will be processed. JW Clark will normally take care of a Section 106 application in the event that you instruct us to do a sewer connection for you, this includes doing all the paperwork, sending it off to the water authority and keeping track of and chasing progress.

OFWAT’s regulations state that a Water Authority must make a start on a Section 106 application within 15 working days of the water authority receiving it. In the event that any queries are generated as a result of the initial application, once the water authority receives an answer to their queries, they have another 15 working days to respond to and continue with the application. With this in mind, it is important to start the process of applying for a Section 106 well in advance of when the sewer connection needs doing.

In relation to a sewer connection, a Section 50 application to Highways is needed in when the sewer connection requires us to ‘dig up the road’, i.e. to excavate in any part of the Highway, either the footpath, verge or carriageway/road, sometimes in all three. 90% of public sewers are in the Highway, so most sewer connections will require a Section 50 application. We will normally have to do this for you. For this we must have operatives and management NRSWA accredited and we have to hold £10million public liability insurance. Plus of course we need experience in this kind of work, and we have many years’ experience.

Before we can apply for a Section 50 we have to obtain utilities drawings for any apparatus that may exist in the Highway where we are to dig. This will normally include BT, Electric, Gas, Water & sometimes Virgin Media or similar. There is a cost to obtaining these utilities drawings, and this will always be included in a quote for a sewer connection. In some cases there may be no gas or Virgin Media in the vicinity, but in this instance we have to get written permission from the utilities companies that no apparatus exists, for which there is still a cost. We need these drawings so we know where existing utilities are in the Highways before we start digging, and Highways have a duty to know that we have obtained drawings, so no Section 50 application can be made before we have these drawings.

Once we have the utilities drawings we can make our Section 50 application to Highways. This will include us sending in our proof of accreditation and insurance, a site plan detailing the work we wish to do, our traffic management proposal and the Section 106 that we have obtained from the water authority. The Section 50 will then be considered by Highways for processing, which can take anything from a few weeks, up to 10 weeks in some instances.

The fee to Highways for a Section 50 will normally range from £500 - £800, deepening on the area. However, there are sometimes further costs in the event that, for example, a road closure is required or that parking needs to be restricted. Our quote to you will always include all such fees, and will include for us to carry out the whole process for you, from start to finish. For a quote click here.

Yes.  We will always arrange inspection of the actual sewer connection by the water authority as part of our quote to you. As far as any ‘private lateral’ is concerned, this will often need inspecting by Building Control in the event that it is not being adopted by the water authority – which is often the case with 1 new build or a very small development.

Not normally. Water authorities try to discourage anything other than foul going into their foul and combined sewers, except in extenuating circumstances. In the event that there is a dedicated surface water sewer in the Highway there is more likelihood of being able to discharge rainwater/surface water into this, however their preference may still be for rainwater to discharge into soakaways or by other means. This is all dealt with in the application.

It all depends on the nature of the job. If the work relates to a ‘new build’ and there is approved planning permission, then the rate will normally be zero. For existing properties the rate will normally be standard 20%, however there are some exceptions. For example, the VAT rate for a barn conversion is 5%.

Location:
Hargrave

Key Tasks:

  • Apply for Section 50 license to work in the highway at Northants County Council
  • Apply for Section 106 license from Anglian Water
  • Dig from site boundary and lay clay pipes to existing AW pipe in road
  • Connect to sewer via junction insertion
  • Cover with 5-14mm granular fill 
  • Backfill and re-instate as per Council regulations

Sewer Connection

Our customer bought a piece of land for a new build property in Hargrave. The original site was waste land so would require a way of disposing of the foul and surface water. Whilst the surface water went into *soakaways* in the back garden, the foul water needed to be disposed of into the existing Anglian Water sewer running through the middle of the village.

We connected into the sewer using a junction insertion method and continued with our clay pipes up to the site boundary where it could be switched back to plastic pipe. This required obtaining a Section 50 license from the local council and a Section 106  approval from Anglian Water. 

The job was made all the more possible as our employees are New Roads & Street  Works Act (NRSWA) qualified allowing them to work in the highway.

Here is what the customer had to say:

Hi John,

I hope you are well.

I thought I would send you a little note, to thank you and your guys, for an exceptional job at Hargrave. As I'm sure you are aware getting trades people on site when they are supposed to be there, to do the job they are booked to do, is not always easy. However, it was a pleasure to know that your guys turned up when they were booked,were clean, tidy and efficient.

The job they did was first class, and they were very helpful with any information I requested. Please pass on my thanks to them. I look forward to using your companies services on our next project.

Yours sincerely.

Ian Blakeley.
