WaterWatch

The next generation of water distribution system management is a decision support application that provides extensive data integration for improved forecasts and operations. Our WaterWatch Software merges all water system data sources and creates a central repository of hydraulic simulation, data management review and reporting to address key questions you have about your water system.

WaterWatch Software provides valid operational recommendations by leveraging engineering principles of hydraulic models combined with operations analytics and optimization algorithms that allow water distribution systems to safely and securely:

  • Forecast future utility operations, energy demands, and energy costs;
  • Generate new utility operating strategies;
  • Facilitate energy demand response participation at the utility; and
  • Empower water utility operators to proactively explore new operations based on future energy rate structures or energy demand response programs.

How it Works

WaterWatch Software enables you to integrate water utility data sources to provide accurate, real-time forecasting and operational simulation of complex water systems. Water agencies can visualize system performance at multiple scales to inform operational decisions, perform long-term infrastructure planning, and more efficiently generate comprehensive reports for the system, assets, and at the customer-level.

Impact and Partnership

As a rapid decision support system, WaterWatch Software is unique in its ability to quickly and accurately provide operational intelligence for all aspects of water system management, without the time commitment or specialized engineering skills required to use water system models like EPANET. WaterWatch Software is designed to be a water system operator’s daily companion, helping to answer any sort of “what if” scenario to refine the ability of operators to make decisions to meet new objectives. The software tool brings the hydraulic model into the operations room for long- or short-term system analysis. It allows for continuous evaluation of current situations, instead of waiting for engineering modeling studies which only evaluate a moment in time. It is a collaboration tool for water system engineers, planners, and operators to work together to take system management to the next level and optimize resources in ways never possible before.

WaterWatch Software is a research tool built at UC Davis to improve our management and operations of water distribution systems through the advanced ability to evaluate current or future operations rapidly and continuously using real-time system data. There is no other software product on the market with equal capabilities.

UC Davis is launching this software with the potential to be as impactful as the EPANET software but for the water sector. This software is for utilities who value innovation and exploration, and are interested in advancing the next generation of modern water system resource management.

Since the tool integrates all water system data and its hydraulic model, there are endless opportunities for configuring the software to meet any objective. The WaterWatch User Group will have a direct stake in deciding the priorities for software development with a seat on the Advisory Board. Early users will also obtain significantly discounted rates. Our vision is for WaterWatch Software to be a collaborative software tool for the water sector community to propel and advance the solutions that matter most to water utilities.

Project Background and Support

This effort was funded by the California Energy Commission project EPC 16-062, ‘Advancing Energy Demand Response in the Water Sector.’ The project goal is to develop and pilot a technology that would enable water utilities to participate in an increasingly dynamic energy market, while continuing to provide safe and reliable water to their customers. The end product, WaterWatch, is a comprehensive software that goes beyond energy management. Our pilot site partner is the Moulton Niguel Water District where our technology solution is being tested throughout 2021 in their existing water distribution systems to increase the flexibility of energy management and decrease energy costs. We have also partnered with the California Water Efficiency Partnership (CalWEP) to increase the user base of our products and administer the user support program.

Frequently Asked Questions

WaterWatch Software organizes and processes complex utility data (e.g., ongoing and historical operations, SCADA, customer billing data, etc.) to provide accurate forecasting and recommendations for complex water system operations. It allows water agencies to visualize system performance at multiple scales to inform real-time operational decisions, perform long-term infrastructure planning, and generate comprehensive reports at system, asset, and customer levels.

WaterWatch Software is specifically targeted to water utilities interested in optimizing resource management through data analysis. Further, for water utilities looking to compare and select operating strategies for their tanks, reservoirs, pumps, or valves on any number of objectives including minimizing energy cost or greenhouse gas (GHG) emissions, participating in electric load shifting, developing maintenance scheduling, managing seasonal operations, and more. This product would also benefit water distribution systems that would like their data organized in order to generate comprehensive reports to improve efficiency programs, plan long-term infrastructure changes, audit leak loss, perform asset management, and more.

Water utilities can expect an enhanced ability to manage resources of water, energy, GHG emission, and energy costs. The software allows managers and operators to visualize and observe their entire system and empowers agencies to quickly respond to or make informed decisions based on comprehensive and accurate forecasts and reports. Utilities can also respond to real-time operations or events (e.g., emergencies, PSPS, etc.) and select operating strategies that best meet their goals from hydraulicly modeled scenarios. With these simulations, agencies will have the ability to perform infrastructure planning (e.g., capital assets, leak loss detection, etc.), maintenance scheduling, and make both short and long-term operating decisions.

Specific software development and design consideration was given to ensure the quick generation of reports. Utilities will have the capability to quickly and accurately generate comprehensive system and customer-level reports. For example, customer billing data can be analyzed for the life of the accounts and forecasted into the future using machine learning; water demand for each unique pressure zone can be forecasted and calculated for leak loss detection and approximation; and SCADA data can be viewed over a period and forecasted.

  • Collect and Analyze Data. The software integrates SCADA, customer billing, asset characteristics, GIS information, and hydraulics into a single package – allowing a utility to easily observe the entire system. Reporting on system-wide or per-asset performance is simplified by consolidating all data into the software environment.

  • Analyze Virtual Assets. Manage virtual assets outside of typical hydraulic models (e.g., pump stations, water customer meters, District Metered Areas, etc.) and make them available for analysis and reporting.

  • Visualize Scenarios in Response to Sourced Data. The software continuously streams and applies up-to-date information from various sources (e.g., SCADA, customer billing, weather stations, energy prices, etc.) to provide accurate reporting and forecasts. Users can visually compare different operating strategies and scenarios on the system to inform decision making.

  • Generate Optimum Operating Strategies. Instead of short-term pump schedules (e.g., precise on/off controls for the next 24 hours), long-term pump and valve policies (i.e., programmable logic controls) can be generated based on provided operator criteria (e.g., reduce maximum service pressure, maintain minimum flow, GHG reduction, energy load shifting, and more). Policies need only be deployed once as part of a larger capital improvement project; water utilities can have confidence that the recommendation will not change or need constant review.

  • Perform Real-Time Hydraulic Simulations. The operator can easily compare scenarios based on historical, real-time, and forecasted conditions. The software maintains all scenarios with real-world decision making using comprehensive machine learning and constant hydraulic modeling to ensure all scenarios are available to operators for comparison and recommendation at a moment’s notice.

  • Forecast Customer Demands. The software uses machine learning and the standardized EPANET hydraulic engine to forecast and self-correct customer water demand estimates for each virtual District Metered Area (DMA) in real-time — quickly processing even the most complex datasets. One application is the use of demand forecasts to improve the accuracy of hydraulic simulations and estimate high-resolution leak loss.

  • Make Real-Time or Offline Calculations. Connect to real-time SCADA and customer billing data to run historical, real-time, and forecast simulations. Offline analysis of the hydraulic model alone is also an option.

  • Customize the Software. Source code is available. Utilities can program add-ons or customize features in-house to meet unique agency needs.
  • Various reputable historical and real-time data sources are integrated to provide accurate and optimized scenario forecasts such as:
    • Weather (historical and forecast)
    • Marginal GHG Emission Factors
    • Energy price data
    • SCADA
    • Customer Billing
    • GIS map backgrounds
  • Staff will interact with a user friendly and familiar Windows environment to generate and compare countless operational scenarios (e.g., optimizations for customer demand, resource management, load shifting, etc.) for improved resource management. It integrates well into existing business operations and does not require computer upgrade improvements.

  • Early adopters can work directly with researchers and developers to advise on additional features and add-ons that would be beneficial to impacting 21st Century resource demand management.
  • Early adopters will have the opportunity to partner with UC Davis CWEE and its developers to direct the customization of the software to bring about the vision of a modern water resources management tool.

  • WaterWatch Software has the capability to accurately generate safe, long-term operating policies for any pump or valve. Accurate simulation and forecasts can be provided due to behind-the-scenes machine learning mechanics that aid in filling in gaps of incomplete datasets.

  • Assets in WaterWatch can be controlled in one of three ways:
    • Operational strategy (e.g., reservoir level controls, pressure controls, etc.)
    • Machine learning (i.e. learn from SCADA the actual decisions); or
    • User controlled (e.g., operator override for specific periods such as maintenance, pump rotation, etc.)

  • The software constantly reruns full hydraulic simulations (instead of performing a limited mass balance) to inform accurate results and give high-resolution forecasts. Additionally, the software can immediately incorporate any updated change (automatic or manual) and provide a new hydraulic forecast and recommendation report automatically without the user needing to click anything.

  • Even at a high resolution, the software has the capacity to smoothly support simultaneous calculations and scenario processing (e.g., the user can create a new scenario while simultaneously machine learning SCADA and forecasting the hydraulics).

  • Our software has integrated several premium features including real-time data connections, optimizations tools, machine learning tools, automated reporting, and much more.

Modern operating strategies rely on policies generated by teams of operators and engineers that maintain service pressure, flow, water storage, and water quality standards.  WaterWatch Software produces policies that are understandable by human operators to approve, modify, and incorporate into existing or new operating strategies at their utility. Because policies automatically adapt to real life changes, and only need to be regenerated occasionally based on changes to utility operations, significantly less time is needed by operators to interface with WaterWatch. The operator can always make adjustments or set policies for any interval (weekly, monthly, seasonal, etc). This is in contrast with typical software recommendations that utilize pump schedules that require frequent daily adjustments and are not adaptable to real world changes without operator input.

The software suite deploys engineering principles and algorithms in all circumstances as the primary drivers of scenario building and recommendations. Machine learning is used as the fallback tool if other approaches are not available. It has the ability to take historical measurements (SCADA pump flow, settings, etc.) and run an algorithm to fill in data gaps with the information available. Machine learning provides the best dynamic estimate when compared to a standard static interpolation of data. Machine learning is constantly rerunning its analyses against real values to maintain accuracy over time in order to create a better algorithm for future processes.

WaterWatch Software forecasts and considers classic hydraulic modeling and real world operational assets as part of the suite (pipes, valves, pumps, pump stations, reservoirs, DMAs, and water customers). The software generates recommendations for pumps and valves (on/off and when)

  • Pumps: status and RPM
  • Valves: status and settings
  • Pump Stations: energy price structure, greenhouse gas emission factors

Scenarios are different operating strategies that the software maintains simultaneously. The software can keep multiple scenarios up-to-date simultaneously so the user can immediately compare real life estimates under different scenarios; they are always available and correct for the user to immediately compare or select. Example scenarios that the user can create include:

  • “Pump Station is Offline”: the user would disable a pump station‘s controls due to maintenance and the remaining assets will follow their policies to operate without the pump station.

  • “Energy Demand Response”: the user adds a policy to pumps that pre-fill their water storage before 5pm, and deactivates their pumps between the hours of 5pm and 8pm.

  • “Optimized Energy”: the user utilizes the optimization tools within WaterWatch to generate new operating policies (or strategies) for all pumps to minimize total energy use.

  • “Isolated Zone”: the user deactivates all supplies into a DMA and reviews the hydraulics to report the time until a water storage reservoir would drain to the target level.

The UC Davis CWEE long-term vision is to integrate a secure cloud-based data reservoir as a platform for WaterWatch Software to streamline data collaboration across entities. This environment will give data owners complete control of how derivatives of their data will be used for the lifetime of their data.

Other specific planned upgrades to WaterWatch Software in develop include:

  • Energy intensity calculations
  • Asset management tools
  • Pipe break frequency reporting
  • Evaluate water and energy conservation measures and benefits
  • Leak loss detection and approximation
  • Hydraulic model construction and editing tools
  • User-defined report generation
  • User-defined water demand event (e.g., drought scenario)
  • Advanced policy optimizations techniques
  • Recommended creation of new district metered areas
  • Mac OS compatibility
