The Solution
-
Perform Dynamic Water Quality Modeling
InfoWater and InfoWater Pro model the movement and fate of water quality constituents as they travel through the network during a dynamic simulation period. They work within Esri ArcGIS and ArcGIS Pro respectively.
With InfoWater / InfoWater Pro, you can model:
- Chemical concentration – Compute the concentration of the specified chemical throughout the network
- Water age – Model the changes in age of water over time throughout the network
- Source tracing – Perform ongoing computations to determine the fraction of water originating from one or more specified source nodes, like junctions, tanks or reservoirs
The dynamic water quality models in InfoWater / InfoWater Pro accurately simulate both conservative species - like fluoride - and reactive species - like chlorine and trihalomethanes (THM).
Finally, InfoWater and InfoWater Pro allow input of equations linking multiple substance accumulation and decay, distinguishing itself from standard first-order chlorine modeling.

Optimize Unidirectional Flushing Sequences
Unidirectional flushing (UDF) restores hydraulic capacity and improves water quality by removing stagnant water, as well as mineral and sediment deposits, that have accumulated over time. In addition, UDF uses significantly less water than traditional cleaning methods.
The UDF function in InfoWater / InfoWater Pro helps water utilities develop effective unidirectional flushing sequences for each flushing zone by quickly identifying which fire hydrants and water main valves should be employed for proper cleaning. It can also help you avoid excessive pressure drops to maintain the desired level of hydraulic performance across your distribution system while UDF is underway.
InfoWater UDF also computes minimum flushing time, total flushing volume and pipe length, flushing velocity of every pipe in the sequence, shear stress for every pipe in the sequence, and available flow at the minimum residual pressure.
The benefits of proper UDF sequences not only instantly improve water quality in your system, but they can also inform asset management procedures by identifying pipes that may have leaks.

Track Sanitary Pollutant Loads
The right tools enable you to develop effective water quality management programs. In turn, they improve safety practice, help you deliver an acceptable level of service, and can prolong the useful life of sanitary system infrastructure. InfoSWMM provides powerful and efficient stormwater and sanitary network water quality computational capabilities. These functions enable users to simulate H2S generation, rates of microbially-induced corrosion, sediment transport and deposition, pollutant concentration, biochemical oxygen demand and pollutant loading and build-up. You can also trace pollutant sources to identify domestic, commercial, and industrial contribution and their impact on receiving waters. With this information, system managers are empowered to take the right operational actions to subsequently reduce pollutant loads.

Use Green Infrastructure to Reduce Pollutant Release
XPDrainage, an Innovyze drainage design tool, incorporates LID best practices for designing green infrastructure to reduce stormwater runoff. By taking a “treatment train” approach, stormwater controls in XPDrainage are linked and informed by their effectiveness in line with EPA Best Management Practices regarding green infrastructure. You can effectively design and evaluate the performance of swales, filter strips, trenches, raingardens, ponds, permeable pavements, and more in considering the most ecologically sound method for deterring pollutant wash off from entering your drainage network, and ultimately surrounding river systems.

Protect Receiving Water Systems
Combined Sewer Overflows (CSOs) can negatively impact local ecology if they occur with high frequency and volume. InfoSWMM helps you to determine the impact of infiltration and inflow (I&I) on CSOs while also providing an opportunity to control site runoff using green infrastructure. You can estimate the pollutant loads associated with stormwater runoff and evaluate LID best practices for reducing wet weather pollutant loads. ICMLive operates as a live integrated catchment model that brings in field telemetry, supervisory control and data acquisition (SCADA) historian, and radar data. With a near-real-time view of system performance, as well as a forecasted view on rainfall impacts, your team is empowered to take preventative operational actions to reduce CSO volume and frequency. In turn, these tools enable engineers and operators to work deter CSOs – resulting in ecologically sound management of combined sewer systems.

Clearly Convey Action-Oriented Results
These solutions provide an invaluable tool set for engineers, system managers, and operators to formulate sound plans for protecting water quality for distribution networks, sanitary systems, and receiving waters.
But these plans are most influential when they are easily understood across the enterprise.
InfoWater / Infowater Pro and InfoSWMM integrate with ArcGIS/ArcGIS Pro or in a similar standalone environment. They provide familiar and easily accessible reports in color-coded maps, graphs, and customized tabular formats to clearly indicate the best options available for protecting water quality.
XPDrainage lets you compare pre- and post-development mitigation scenarios to clearly represent impacts for clients and other stakeholders.
ICMLive is valuable to engineers and day-to-day use in operations. Outputs from ICMLive provide a clear guide for preventative actions that can be taken to reduce CSOs before they become a risk.
