The Newark Sewer Scheme

Severn Trent Water is to commence a major project to undertake replacement of sewers across Newark. This

scheme involves more than 20 kilometres of old pipes being replaced with new, larger ones, over the next

three to four years. The scheme will be using specialised tunnelling machinery to replace the sewers. The

tunnels, which are large enough to drive a transit van through them, will reduce the number of roads it has

to dig up to install the sewers.

The work, which will start later this year, will include a 2.8 metre diameter tunnel from Crankley Point sewage

treatment works to the southern end of Millgate and a 1.5 metre diameter tunnel under Queens Road and

Sleaford Road.

Severn Trent has appointed the BNM Alliance to carry out the £60million project. The BNM Alliance

comprising NMCNomenca and Barhale plc will deliver the project. NMCNomenca, a division of North

Midland Construction plc have asked our clients to undertake the recycling of the excavated material which

will include crushing and screening activities.

Atkins Ltd on behalf of Severn Trent Water submitted a revised EIA Screening Opinion request to

Nottinghamshire County Council on the 14th May 2015. A negative screening decision was issued by the

County Council on the 7th October 2015.

© Atkins Ltd – Plan Accompanying 15/SCR/00007 - Request for screening opinion for Newark Sewers Strategy

Project (comprising the construction of a 3km new transfer sewer between Millgate/Farndon Road and

open cut/trench techniques; and associated works at Crankley Point STW). Site at Transfer Sewer from

Millgate/Farndon Road to Sewage Works, Quibells Lane, Newark on Trent, Nottinghamshire, NG24 2ED.

The Newark Sewer scheme according to the specification produced by Atkins, will involve the upgrade of

11.6km of sewers across Newark, the sewer upsizing will take place within the public highway. This upsizing

will utilise traditional open cut/trench construction replacing existing sewers, sometimes at increased

depths. This element of work is described as taking place over a 3 to 4 year period, working on 10 to 15m

lengths at a time in 2 or 3 locations around the town at any one time.

A new 3km transfer sewer will also be constructed using trenchless construction, i.e. tunnelling along a route

of Castlegate and Northgate to Crankley Point Sewerage Treatment Works via Quibells Lane. This aspect will

involve a 20m diameter, 25m deep pumping shaft and a further 7 shaft access points (of between 4m and

10m in diameter) to allow tunnelling access. This tunnelling is described as going to take place on a

continuous 24 hour period over an anticipated 1 year duration.

During the tunnelling and trench digging there will be waste arising from spoil removal. NMCNomenca have

asked our clients Laffey’s Ltd to process this material. The Newark Sewer Strategy is vital to the growth and

development of the Town. It will reduce the current impact of flooding to properties in Newark, it will remove

the restrictions on future development growth arising from an ageing sewer network and will realise an

improvement in waste water quality discharged into the River Trent.

The Processing of Waste Arisings

The processing and recycling of the excavated tunnel material will include crushing and screening activities,

some of the material will be re-used in the laying of the new sewers. The material will fall within the definition

of non-hazardous inert waste.

The activity will involve mobile processing using temporary crushers and screeners. Details are still to be

confirmed but it is expected to involve the processing of up to an estimated maximum of 50,000 tonnes per

annum over a period of three to four years. Progress and timing of the actual sewer scheme will dictate this

as a supporting activity.

The Atkins Ltd project description estimates 39,000m3 of spoil being generated by the tunnel and shaft works

which will need to be removed from site. Taking account of relevant multipliers this will equate to between

56,160 tonnes and 68,640 tonnes of material dependent upon the makeup of the material and moisture

content. Atkins estimated that this would require 1,950 wagon loads of spoil to be moved, with them further

estimating this to represent an average of 37 lorry loads per day. Although they think this may peak at around

50 loads during the period of carrying out the bulk dig for the pumping station.

We understand that the tunnelling will result in material being temporarily deposited at tunnel exits around

the streets of Newark. From those locations our clients will then collect the material for recycling. We are led

to believe that BNM Alliance are currently proposing to work 7 days per week, consequently if this is so then

our clients activity will need to take place over 7 days per week as well. Atkins Ltd estimate the stockpiles for

the tunnelling and shaft works will involve between 250m3 and 500m3 of material remaining in the Newark

Sewer Scheme holding areas.

Our clients intend to utilise a small shuttle fleet of lorries. Overall lorry movements will be greater during the

period of tunnelling and shaft works and lower during the period when only the traditional open cut/trench

construction replacing existing sewers is undertaken. Lorry movements will probably need to operate from

07:30 to 19:00, processing activity is likely to occur between 08:00 and 17:00 daily.

The waste arising from the Newark Sewer scheme will not all be taken to the proposed application site, soils

will go to South Muskham Lakes where it is being used to construct a new lake bund.

Work on the main bulk of the tunnelling and shaft works is already underway this accounts for the main bulk

of material, much of this is currently going to Muskham Lakes. Depending upon the timing of determination

of this application the application site is likely therefore to be primarily used for the material arising from the

traditional open cut/trench construction replacing existing sewers and water pipes.

The proposed development will involve the following:

Time Period 3 Years from date of grant

Lorry Movements 20-25 per week (1,000-1,250 per annum)

Tonnages 360-450 tonnes per week (18,000-22,500 tonnes per annum)

Processing To occur on a campaign basis, estimated to be 2 or 3 days every 4 to 6 weeks

BNM Alliance propose to undertake environmental control works including:

Vehicle sheeting;

Hard standing at access and egress points to prevent deposition of mud onto the highway;

Vehicle wash at Crankley Point; and

Road Sweepers

At the screening stage in 2015 Atkins Ltd had identified a site at Drove Lane, Winthorpe as a potential location

for a material recycling site. They also identified a landfill site at Balderton as a potential location for disposal

of material which cannot be recycled.

The principles underlying the Newark Sewer Scheme with regard to waste arisings is to:

1. MINIMISE the generation of materials

2. REUSE AND/OR RECYCLE materials for the Newark Sewer Scheme

3. REUSE AND/OR RECYCLE materials for use on other projects

4. DISPOSE of at licensed landfill sites

Our clients processing activity will generate backfill material for the open cut/trenching works and generate

other materials utilising crushers and screening for other construction projects. Our clients have extensive

experience of undertaking such activities on large infrastructure projects.

The Current Position - Tunnelling

Queen's Road - Installation of the shaft in the Mount School playing field is complete and the ‘Mount Mole’

has commenced tunnelling. The Mount Mole is now over half way on its journey below the ground towards

the next shaft on Sleaford Road. This is the first of six tunnels that the Mole will dig in Newark. There are also

another three tunnel machines coming to town in the future which will be used to construct nine tunnels in

total.

Sleaford Road - Construction of shaft 21 has progressed well, the tunnel machine launched from Queens

Road will come out of the ground here later in the year. Shaft 22, being constructed on the corner of Harrisons

Way, is now excavated to full depth. Once the 'Mount Mole' has tunnelled from Shaft 20 (Queens Rd) to Shaft

21 (Sleaford Rd) it will be lifted out of the ground and lowered back in here, ready to tunnel back towards

Shaft 21 again...

Quibells Lane Piling Rig – BNM Alliance have now completed the launch shaft for the main tunnelling

machine, ready to be prepared for tunnelling operations later in the year.

The Current Position – Open Cut Trenches

Eton Avenue Hawtonville - The temporary pumping station is now complete and operational. BNM Alliance

began laying new sewerage pipes in January. BNM Alliance have started laying new sewers on Pierson Street

in April 17 and continue to work along Eton Avenue.
