5 EPA Challenges Drinking Water and Wastewater System Challenges Water Scarcity Climate Change Increasing Population Energy Uncertainty Aging Infrastructure 36 states anticipating water shortages. Changing climate conditions are challenging infrastructure and resources. Population demands are depleting source waters. Energy instability are causing uncertainty for utility operating budgets. Infrastructure maintenance can cost in the trillions. Energy Challenges Water Scarcity Climate Change Increasing Population Energy Uncertainty Aging Infrastructure 5

12 Energy efficiency offers huge potential for cost savings 12 4

13 How to rise to the energy efficiency challenge and cut your operating costs. 13

14 Use Energy Management Information System (EMIS) and make energy efficiency a routine integral part of your processes: EMIS brings actionable intelligence through regular measurement, monitoring and control, and helps you take the right decisions EMIS spots new opportunities for cutting operating costs and enables you to update targets and action plans or draw up new ones The result reduced energy per MG of wastewater treated lower carbon footprint compliance with environmental regulations 14 7

15 Energy management can be simple. Just scale up as your needs and investment capacity evolve. 15

16 Use your energy better and find new ways to cut operating costs Energy Optimization System for single- and multisite wastewater treatment 16

17 Energy Optimization System An Energy Management Information System for operators Our system enables you to understand and reduce your energy consumption for higher quality water treatment for less kwh more water treated for less kwh and kj identify and benchmark best practices across your sites negotiate better utility contracts, avoid billing errors, sub-bill more accurately optimize your energy sources improve your energy quality improve your CO2 emission control for a lower footprint comply with environmental laws and regulations EMIS for a sustainable wastewater industry. 17

18 Energy Optimization System Built on KPIs validated by wastewater operators Electrical energy required to treat one MG of water kwh/mg Electrical energy required to reduce BOD kwh/lb Electrical energy self-sufficiency: ratio of energy produced to energy consumed percentage Total thermal and electrical energy cost and breakdown per utility Electricity ratio: by process unit according to required benchmark structure percentage Electrical energy required to lift raw water lifting kwh/mg Electrical energy consumption for sludge dewatering process kwh/t of dry sludge CO 2 emissions related to energy and chemical use t O2-eq 18

19 Energy Optimization System Seamless and smart Energy Optimization System doesn t disrupt your processes your installed base your finances assign it to Opex not Capex Energy Optimization System is so smart it s simple to use don t waste time keying in data to learn a couple of hours training to interpret it supplies actionable intelligence in clear meaningful displays 19

20 Energy Optimization System Simple and ready-to-go Energy Optimization System is plug n play Make it part of your existing environment and wastewater plants process control systems Interface it with utility-wide other information systems smoothly and seamlessly Use it to source and consolidate all relevant input from process control systems, energy supervisory systems, and external data bases 20

21 Energy Optimization System Scalable Flexible and modular Make the most of your installed base, sizing your metering architecture and information system to match your plants configuration Then scale up for size as your energy management objectives and investment capacity evolve 21

22 Energy Optimization System From single site to multi-site When Energy Optimization System is installed in one site, it automatically consolidates that site s energy information into multi-site intelligence 22

23 Energy Optimization System From single site to multi-site Optimized metering and communication architecture The architecture is designed to optimize new sites and existing installations Flexible and open-ended, it reads and transmits plant s energy data at high speed At plant level Plant data management Energy Optimization System aggregates energy data at load, process, line, and plant levels To compute KPI scores, it acquires data from the process SCADA It converts the raw data into KPIs It logs this information at load, process, line, and plant levels 23

24 Energy Optimization System From single site to multi-site Enterprise data management It aggregates information from different plants at utility level for a utility-wide picture of total energy usage, costs, and performance At enterprise level Enterprise HMI Strategic utility managers can visualize enterprise-wide energy intelligence on analytical dashboard displays from plant to plant and country to country Connection to other information systems This information is stored at utility level and can be fed into the utility s other information systems 24

25 Energy Optimization System Fully customizable web-enabled dashboards Configure and display easily, in a few minutes, dashboards that match your profile and needs from a pre-defined library that includes wastewater treatment KPIs Access the chosen metrics rapidly through dynamic and meaningful contextual displays and take the right decisions Drill down level by level to country, plant, line, process, and load from views of data aggregated across your enterprise 25 7
