Challenges of AMP7 and Beyond Pumps in Perspective A major change in the composition of wastewater over the years Moving to huge quantities of man-made materials as well as a dramatic increase in sand and grit content Significant increase in the number of clogging and jamming incidents Many water reducing initiatives, such as rainwater harvesting further changing the composition Expectations: - Wastewater pumps have to be able to handle modern day wastewater - Consume less energy and offer lower cost of ownership.
What do OFWAT think is important? Innovation must be at PR19 commitments the core of every company to deliver Resilient Pump Systems long-term resilience, great customer service and affordability. We Reliable Pump Stations All With expect companies to with a reduced risk of look beyond their Increased failure. boundaries in addressing the Cost Pumps capable of challenges they face. managing a variable Efficiency demand. Effective pump maintenance programmes.
The Status Quo; Our wastewater pump stations have changed How has technology evolved the industry approach to little over the past 40 wastewater transport solutions? years. Many applications have not been updated or radically changed at all in this period. Is it any POWER CONSUMPTION MAINTENANCE wonder that we PURCHASE experience the same POWER CONSUMPTION Efficiency % MAINTENANCE and sometimes PURCHASE worsening results with continual OPEX cost increases being the current solution. 1990 2017 2025 5
5 Years of S-Tube: Unfulfilled potential, why? Wastewater Impellers Designed for High Efficiency Without Compromising Reliability Performance of the Frameworks Performance of the S-Tube impeller: combined SE and SL pump program: • BEP= 83.3 % hydraulic efficiency • Head up to 70 m • BEP = 74.5 % • Flow to to 270 I/s overall efficiency (972 m 3 /h) • Approx. 55 % of the Culture curve is above 75 % hydraulic efficiency • Free passage 110 mm Awareness LESS BLOCKING Reliability WIRE-TO-WATER EFFICIENCY The unique S-tube impeller Reduced components and reduced The SE/SL pump design reduces wear parts with flat efficiency electrical, mechanical and offers unmatched curves ensure reduced but hydraulic losses without free spherical passage and implementable maintenance compromising reliability high hydraulic efficiency
5 Years of S-Tube: Grundfos have Wastewater Impellers Back to Basics developed the first new wastewater hydraulic design the Closed type of impeller, with open industry has seen in 20 properties. years. The innovative design breaks the No vanes compromising free spherical passage. convention of traditional derivatives The bigger free spherical passage of open, closed or the lower risk of clogging to occur “S” derives from the extension of a semi open designs, by natural pipe leading through the pump Free Passage + incorporating the best Efficiency + features of both. S-tube impellers are wet- Wear Rates = 0.5 balanced. No need to make trade offs.
5 Years of S-Tube: In the last 5 years, we Solids Handling with up to What Did We Say? have supplied over 160mm Free Passage 5000 units to the UK market, consistently Robust as a tube or section of Free delivering radical Best in Market Efficiency up to pipe.

This in Service Efficiency turn is lowering compliance risk, and stimulating change Extremely low wear rates No expensive add-on and high reliability. across our client systems or electronics. organisations Not Lowest Advanced Vibration Add-Ons
What HAS Been Done? Resilient Pump Systems Reduction in KWh Reliable Pump Stations with a Reduction in Work Hours reduced risk of failure. Pumps capable of managing a Reduction in Waste Removal variable demand. Effective pump maintenance Asset Availability ” Uptime ” programmes.
Demonstration The technology is Wet well Clean; proven across Saving £6,720 a year hundreds of UK wastewater transfer Calls Before Per Year = 32 Man Hours Before Per Year = 256 hours stations, testimony’s continue to highlight Calls Now Per Year = 8 Man Hours Now Per Year = 64 hours the tangible benefits users are receiving. Savings £9,600 Total Savings Per Year = £16,320 “We quickly realised the opportunity to increase performance, reduce the chance of clogging, whilst considering all other cost saving implications. We estimate that £16,000.00 in maintenance costs have been saved.“
Innovation must be at We have delivered the first radical innovation for the wastewater industry, which is realising real benefits for users, facilitating a step the core of every change in behaviours and increasing cost efficiency. company to deliver long-term resilience, great customer service and affordability. We expect companies to look beyond their POWER CONSUMPTION MAINTENANCE boundaries in PURCHASE addressing the POWER CONSUMPTION Efficiency % MAINTENANCE challenges they face. PURCHASE 1990 2017 2025
