Simon Hinsley Project Sponsor
LEGACY BUILDING Delivering the Birmingham Resilience Project
Clean Water Modelling Advisory Group Autumn Conference 14th October 2015
1876
Faced with a rising death rate caused by contagious disease,
Joseph Chamberlain forcibly purchases the
Birmingham Waterworks Company
1880’s
Faced with outbreaks of contagious disease, Sir
Thomas Martineau starts the search for an
alternative supply of water to meet future
demand
1891
Having completed his feasibility study,
James Mansergh submits proposals to Birmingham
Corporation Water Committee
VICTORIAN PIONEERS

THE NEED FOR RESILIENCE
We carried out detailed analysis of failure mechanisms
Including flood inundation mapping to determine potential consequences
We identified we needed the capability to take the EVA off-line for extended periods to carry out major maintenance and refurbishment work
PROFILING RISK
We identified we needed the capability to take the EVA off-line for extended periods to carry out major maintenance and refurbishment work
DEVELOPING THE CASE FOR INVESTMENT

BIRMINGHAM RESILIENCE – OVERVIEW
Birmingham
Critical exports
“The alternative supply will allow us to undertake planned EVA maintenance events (up to 50 days every other year), allowing a 30 day ‘dry possession’ of the aqueduct.
It also provides a critical back-up supply in the event of an unplanned shutdown”
11Ml/d
Process Loss
245 Ml/d * (raw inlet) River upgrade,
Dual stream & recirculation
“To provide for a continuous water supply to our customers in Birmingham in the event of either planned maintenance or an emergency shutdown on the EVA and the removal of specified single points of failure from the Frankley WTW process”

Ground Level
• Several route corridors & configurations assessed, some involving extensive tunnelling and others pumping to a high-level ‘break pressure tank’.
• Southern route corridor, with break pressure tank selected as providing lowest NPV & lowest impact
TRIMPLEY PILOT PLANT Optimising the ‘Actiflo’ process & Rapid Gravity Filtration
• £3.0M investment to reduce risk and optimise process design • Commissioned April 15 with 10-12 month trial • Location allows process evaluation on Elan
Valley water, River Severn water and blends of the two

New SynerGEE model of the complete grid being constructed. To be used in conjunction with MISER water resource modelling to support decision making on grid flows. Distribution quality modelling also to be undertaken, to assess impact of using 4 sources of supply in Birmingham.
STRATEGIC GRID MODELLING
Field test calibration against pressure/flow/level as standard, with turbidity/chlorine/pressure transient also recommended

Pump
Throttle is located at DSR inlet
Pumps are not performing in accordance with
assumed pump curve
Valve checks
Pump testing
Sections in red are high priority, as flow rate increases are required for Birmingham Resilience
Sections in yellow require field testing but do not require flow rate increases for Birmingham Resilience

Introduction to ‘The Future Water Supply of Birmingham’ 1891 Thomas Barclay, Water Committee member at the City Council of Birmingham
“Perhaps the heaviest responsibility resting on any local government is the establishment and maintenance of a proper supply of water for those under its care. How unpardonable a failure in this all important matter! Yet how vast the task”
