Achieving TOTEX reductions in wastewater pumping systems MARK HERRING & CHRIS HARVEY

Introduction Achieving the challenges of TOTEX reduction in wastewater pumping systems using innovative integrated intelligent technology Mark Herring Chris Harvey Mechanical Engineer Marketing Development Southern Water Manager Xylem Water Solutions

Key takeaways from OFWAT presentation Mr David Black - Director of OFWAT 2020 Presentation at WWT Conference Tuesday 31st January 2017 “ • Water customers getting the best deal for the long term • Planning for climate change and population growth • Incentives for outcome delivery being more powerful • Common performance (measures for) resilience • Increased transparency and asset integrity • Avoiding paying twice for asset resilience ” • Scope to manage future uncertainty 3

Water industry challenges in wastewater handling • Wastewater network used as a general disposal system for non-biological solids by end user • Pressures to • reduce customer Escalating electrical costs bills • Increasing fuel costs • Growing and ageing asset base • Legal liabilities for failure to protect environment 4

Water industry requirements TROUBLE FREE EFFICIENT ASSET PUMPING MANAGEMENT REDUCED ENERGY SAVINGS INVESTMENT COST TOTEX 5

UK wastewater pumping stations Total number of municipal wastewater pumping stations in UK 37,253 (of which 20,116 < 8kW approx ) Above 8.1kW Between 2-8kW Capital Cost Around 64 % of the assets < 8kW will require 3.1 visits per annum purely for unblocking pumps Considering round distance to site of 40 miles The industry covers 1,596,405 miles per year • consumes 53,346 gallons diesel • produces 762.84 tons of Co2 • risking 39,910 of overflow 6

Wastewater utility challenges

Wastewater utility challenges Asset diversity and selection Southern Water Challenge Supply Chain Solution 4357 sq. miles complex selection… 3240 sewage pump stations 1490 below 8kW 47 different wastewater pump manufacturers + all the variants Wide range of motor/impeller combinations 8

Wastewater utility challenges Reactive operational requirement – blockages Water Company Challenge Supply Chain Solution Clean leading edge impeller Non-biological design solids Improved uniform through-let velocity Leading edge blockage Variable speed drives pre-block detection/reversing functionality Plug blockage 10

Impeller design to improve blockages 11

Operational challenges Reactive operational requirement – sump cleaning Water Company Challenge Solutions New station Collection of • Good wet well civil and controls in-organic design promoted by specification solids in the wet well • Retrospective solutions to existing and adopted asset • Pump activated sump automatic flushing valves Frequent tankering visits • Control system technology to use, Disruption to lowering the wet well the public level to draw floating solids through the Odours pump 12

To truly deliver on TOTEX, reduction in wastewater pumping stations requires a completely different approach; a different way of thinking; one that takes on and beats the challenges holistically. 17

- A new level of thinking, a new level of Existing solutions technology Drives that run Devices to snore Seal leakage an anti-block pumps to clear solids Massive range of detection routine motor impeller combinations •  Senses operating conditions Integrated control system •  Adapts performance IE4 motor efficiency •  Built-in pump protection Adaptive N-hydraulics  Provides feedback Improved Impeller design Existing Supply  Clog detection & pump cleaning Premium eff motors  Self learning energy minimizer chain Solutions  Sump and pipe cleaning  Soft start and soft stop Integrated Control & Drives that combine anti-blocking Automation systems routines, sump cleaning, and energy Flush valves for  Always correct impeller rotation minimiser function sump cleaning  Abuse ‘fiddly fingers’ resistant 18

Southern Water Birdham SPS – Trial Site Trial duration 15 April – 8 June 2016 Caravan park - two Bank Holiday weekends The intelligent wastewater pump system ran the station in its entirety Zero blockages Performed an average of 2 pump cleaning cycles per day 24

Heathrow Airport Customer pain points • To deliver clog-free pumping of aircraft wastewater – some of the most challenging wastewater to pump • Reduce the frequency of tankers to clean wet well Solutions • Clog-free pumping with no emergency call outs • Energy consumption reduced by 53% • No extra investment in enlarged cabinets was required 25

Heathrow Airport ‘ Since installing Concertor we have had absolutely no clogging and the sump remains clean. As well as peace of mind the savings are approximately 87.5% of the annual costs in ’ cleaning and servicing. Ian Jolly Heathrow Airport Water Services Department 26
