Do more better, smarter, faster ... for less, and unlock more value from your sewer infrastructure

AquaTwin Sewer

A comprehensive 64-bit feature-packed modeling and analysis software extension for ArcGIS Pro and powered by the latest version of the industry standard EPA SWMM 5 engine, AquaTwin Sewer leads the water infrastructure digital twin world in modeling capabilities, customer impacts, geocentric and geoprocessing technology excellence. It can effectively be used by both utilities and their engineering consultants in all phases of the urban sewer infrastructure asset lifecycle. All operations of a typical sanitary, storm and combined sewer system — from analysis and design to management functions such as water quality assessment, urban flooding, pollution prediction, real-time control and record keeping — are addressed in a single geocentric environment.

Plan, design, and analyze stormwater, sanitary and combined sewer systems; analyze hydraulic capacity; identify bottlenecks and mitigate overflows and blockages; size detention facilities and their appurtenances for flood control and water quality protection; map flood plains of natural channel systems; evaluate gray infrastructure stormwater control strategies, such as pipes and storm drains; design real-time controls; manage rainfall dependent inflow and infiltration (RDII); optimize BMP and LID designs; create cost-effective green/gray hybrid stormwater control solutions; evaluate resilient solutions; and meet SSO and CSO regulations. The software comprehensive scenario and alternative twin set management capabilities let users quickly create, run, evaluate, visualize, and compare an unlimited number of different pipe sizing, design and operational strategies, mitigation options, and network and pump configurations for improved decision-making.

  • Automatically convert pumps with point features in GIS to links (i.e., from nodes to links).
  • Build link-node connectivity based on GIS data.
  • Handle drainage networks of unlimited size.
  • Use a wide variety of standard closed and open conduit shapes as well as natural channels to accurately portray the existing system.
  • Model special elements, such as street inlet drains, storage/treatment units, flow dividers, pumps, weirs, and orifice
  • Apply external flows and water quality inputs from surface runoff, groundwater interflow, rainfall-dependent infiltration/inflow, dry weather sanitary flow, and user-defined inflows.
  • Utilize either kinematic wave or full dynamic wave flow routing methods.
  • Model various flow regimes, such as backwater, surcharging, reverse flow, and surface ponding.
  • Apply user-defined dynamic control rules to simulate the operation of pumps, orifice openings, and weir crest levels.
  • Time-varying rainfall (precipitation) and evaporation of standing surface water.
  • Nonlinear reservoir routing of overland flow.
  • Snow accumulation and melting.
  • Rainfall interception from depression storage.
  • Infiltration of rainfall into unsaturated soil layers using multiple infiltration methods.
  • Percolation of infiltrated water into groundwater layers Interflow between groundwater and the drainage system.
  • Dry-weather pollutant buildup over different land uses.
  • Pollutant wash-off from specific land uses during storm events.
  • Direct contribution of rainfall deposition.
  • Reduction in dry-weather buildup due to street cleaning.
  • Reduction in wash-off load due to best management practices (BMPs).
  • Entry of dry weather sanitary flows and user-specified external inflows at any point in the drainage system.
  • Routing of water quality constituents through the drainage system.
  • Reduction in constituent concentration through treatment in storage units or by natural processes in pipes and channels.
  • Bioretention Cells (or Bioswales). Bioretention cells are depressions containing vegetation grown in an engineered soil mixture placed above a gravel drainage bed that provide storage, infiltration, and evaporation of both direct rainfall and runoff captured from surrounding areas.
  • Continuous Permeable Pavement Systems. Permeable pavement allows rainfall to immediately pass through the pavement into the gravel storage layer below where it can infiltrate at natural rates into the site’s native soil. In block paver systems, rainfall is captured in the open spaces between the blocks and conveyed to the storage zone and native soil below.
  • Green Roofs. Green roofs are a variation of a bioretention cells that have a soil layer atop a special drainage mat material that conveys excess percolated rainfall off of the roof. They contain vegetation that enable rainfall infiltration and evapotranspiration of stored water.
  • Infiltration Trenches. Infiltration trenches are narrow ditches filled with gravel that intercept runoff from upslope impervious areas. They provide storage volume and additional time for captured runoff to infiltrate the native soil below.
  • Rain Barrels or Cisterns (Rainwater Harvesting). Rain barrels and cisterns are containers that collect roof runoff during storm events and can either release or re-use the rainwater during dry periods. Cisterns may be located above or below ground and have a greater storage capacity than a rain barrel.
  • Rain Gardens. Rain gardens are depressed areas, planted with grasses, flowers, and other plants, that collect rain water from a roof, driveway, or street and allow it to infiltrate into the ground. More complex rain gardens are often referred to as bioretention cells.
  • Rooftop (Downspout) Disconnection. This practice allows rooftop rainwater to discharge to pervious landscaped areas and lawns instead of directly into storm drains. It can be used to store stormwater (e.g., in a rain barrel) and/or allow stormwater to infiltrate into the soil (e.g., into a rain garden or lawn).
  • Vegetative Swales. Vegetative swales are channels or depressed areas with sloping sides covered with grass and other vegetation that slow down the conveyance of collected runoff and allow it more time to infiltrate the native soil beneath it.
  • Create, edit and manage an unlimited number of scenarios using built-in parent-child relationship.
  • Generate new scenarios, switch between existing scenarios, run multiple scenarios, and compare results from different scenarios.
  • Build, view and edit an unlimited number of scenario alternatives with intuitive single-click alternative sets manager.
