Sanitary Wastewater To help you know the sanitary flow contribution from commercial land use and residential population, HYDRA® software provides very flexible tools to organize your data and estimate sanitary flow contribution. You can organize data by land use characteristics, sanitary service area basins, or ownership parcels. It loads flows into the conveyance system on a pipe-by-pipe basis and dynamically routes them through the collection system.
	Stormwater Runoff HYDRA® software is very flexible for how you simulate rain events, both for design storms and actual storm. You can use intensity-duration-frequency (IDF) curves, rain gauges, data from radar, or synthetic rain events. You can model runoff using one of 3 methods. It can simultaneously simulate surface flows in gutters and the inter-related underground conveyance system.
	Infiltration and Inflow HYDRA® software tracks each type of flow separately through the collection system, including sanitary flow, groundwater infiltration, rainfall-derived infiltration, and stormwater inflow -- critical for accurately calibration. Simulate I&I for actual rain events using condition data from maintenance inspections.
	System Design In addition to modeling existing collection systems, HYDRA® software is able to design new sewers and provide construction cost estimations. You provide basic design criteria, and the program automatically finds an optimal solution for the conditions.
	Worst-Case Scenario Analysis How will your sewer system will behave under worst-case conditions? For sanitary sewers with high I/I, or combined storm and sanitary, HYDRA® software shifts the timing of the storm so the peak of the sanitary flows coincides with the maximum peak flows for your storm, in order to show the worst conditions for your design criteria.
	GIS Integration From many years experience working with municipalities, the whole structure and design of HYDRA® software is oriented to GIS. It works with AutoDesk® AutoCAD® products, ESRI ArcGIS™ products, and others.
	SWMM Module Export all the flows and conveyance data from your HYDRA® model to a .DAT model data format to run an identical hydraulic analysis using US EPA SWMM or other programs.

Proven Over Time
Hundreds of municipalities, large and small, have used Hydra, as well as military bases, consultants, and highway agencies. The HYDRA® program has proved it's reliability for over 30 years. Hydra has been an industry standard in the United States and Canada since its start as a commercial sewer modeling computer program in 1973.
