QUALITY SUCCESS
THIS MONTH
INTRODUCTION
This bulletin provides a summary of
the Quality issues picked up from
CQIR Reports, Audit Reports, Non
Conformance Reports, Early Warnings
and KPI’s. The points on the next page
show the amber and red scores that
were raised and escalated for action.
The aim is to bring focus to issues that
require attention, learn lessons and
hopefully prevent repeat occurrence to
improve everything we do.

Statement of Business Need
Water Quality Issues
Buckingham PWSZ has been identified as being a high risk
biofilm area which could lead to coliform failures. Coliform
failures following a depressurisation event in Upper Boddington
village in September 2014 lead to 200 properties being on a
boil notice for nine days. Increased chlorine dosing was done
during the event with some air scouring however this did not
significantly raise the chlorine levels.
De-pressurisation
There have been a number of recent bursts in Upper
Boddington village and the main leading into the village that
have caused depressurisation events. Any burst along the
main leading to the village will cause around 200 properties
in Upper Boddington to either go off water or experience low
pressure due to its elevation. Analysis of the burst clusters
identified that the main in Frog Lane, Upper Boddington,
is particularly susceptible to failure. In addition to the
depressurisation events, around 15 properties in Upper
Boddington are at risk of inadequate pressure in times of peak
demand.
The proposed solution is to install the Newspring ammonia
dosing plant at Deanshanger along with the Cranwell Hypo
and shower units and realign the existing gravity feed to
incorporate flow control, mixing and sampling. The existing
duty/assist pump arrangement at Thorpe Lodge will be altered
to a duty/standby with VSD starters and three remote pressure
controllers in the network. The solution includes installing a
replacement Hypochlorite dosing unit at Cranwell and Ammonia
dosing unit at Newspring.
The project is a great example of collaborative working
between AW Operations, Networks, Asset Management, @one
Alliance, and Subcontractors following on from a Water Quality
incident. The collaborative team worked together to design the
works in December 2014 with a start on site on 5th
Jan 2015
and completion for 31st
March 2015.
Those involved include: Adam Bullers, Adam Ford, Michael
Worthington, Barry Blacklock, Neil
Cross, Paul McLaughlan, Marcus
Chambers, Didem Yakici, Paul Parkes,
Kieran Hannelly, and Stuart Parsley.

ISSUE

ISSUE

PROGRAMME AND DELIVERY ESCALATION (DOT)
2 x red 8 x amber 14 x green
• There has been a delay on delivery of pipes due to late release of final procurement schedule
and long lead period. This has resulted in a three week delay to the project.
• Previously amber due to having to wait for a level control device. Order now received. Installation in two weeks.
Commissioning yet to be agreed. (Amber last month, red this month).
• Planning and consents held scheme up. Waiting for council to agree planning and site entrance. G/W3 not achieved
as scheme moved to AMP6 delivery process.
• Previously red score as G/W5 not achieved. Confirmation now received that permanent lifting beam can be installed
and training arranged. (Red score in Jan, Feb and Mar).
• Some STO items still require corrective action. G/W5 sign off requested but reply still remains outstanding. (Red
score this month and last month).
• Scheme behind programme due to various criteria. Dewatering plant on site. (Amber last month and this month)
• Will not meet project completion date.
• Enabling works on-going. G/W5 dependant on commissioning completion with project remaining at risk.
• Programme slipping due to failed pressure tests, burst mains on existing network, Ops wanting cut-outs of fusion
collars and possible change from slip line to open cut.
• Outstanding works yet to be programmed in. Need to ensure impact plans are followed as detailed miss may hinder
commissioning.
• Team on site. No up to date programme available. Impact plans not approved. No connections or decommissioning
can go ahead until plans approved.
REWORK RESOLUTION
4 x amber
• Still not set up.
• Reworks sheets require submission (on two schemes).
• Reworks items missing from reworks form.
MISCELLANEOUS ISSUES
9 x amber
Supervision of workforce
• Future site manager needs to be confined space trained to adequately exercise supervision.
• No site manager, complications on finishing scheme with impact plans requiring dedicated time to ensure compliance
and how site is constructed up to connection points.
Parish council contact, key stakeholder contact
• Planning permission has still not been granted.
Management and performance of subcontractors
• Direct drill performance has suffered due to supply of poor drilling equipment. Current unit broken down four times.
Subcontractor issues
• Programme date missed again causing reworks.
• Contractor failed to plan subcontractor engagement for second time. Two operatives had no CSCS card. Four
operatives had no two-day H&S induction, EUSR or POSWSH training.
• Supervisor had no CSCS card.
• Four week delay on delivery of chamber covers. No communication with site.
• Would not return to site to carry out reworks. No communication as to why.
