Pipedream©, backed by Wade & Associates training and support, is the best sanitary sewer hydraulic modeling software on the market today. Pipedream© software is licensed and distributed as a supplement to services provided by Wade & Associates, Inc.  Pipedream© considers the complexities and challenges that make each sewer system unique by evaluating special configurations like downstream splits, cross-connections between parallel interceptor sewers, multi-stage pumping stations, overflows and bypasses, off-stream storage, siphons, pumps and forcemains.

What separates our modeling package from others is its ability to model any hydraulic structure or strange configuration. If a hydraulic condition can be explained mathematically, Pipedream© can model it using a unique and patented program called HydroFLEX. HydroFLEX allows Pipedream© to evaluate downstream splits, cross-connections, multi-stage pumping stations, overflows and bypasses, offstream storage, and siphons.

Because Pipedream© routes synthetic diurnal hydrographs through the entire system line by line, you can examine the hydrograph at any time and point. Pipedream© allows users to instantly see a graph of the time-dependent hydrograph at any point in the collection system.

Furthermore, Pipedream© adds flow at each increment of time rather than adding peak flows of all segments. This dynamic configuration gives you a much more accurate simulation, and most importantly, keeps you from doing unnecessary or ineffectual rehabilitation and relief sewer construction. In fact, the theoretical flow rates of our model were within 2% of the actual flow monitor data in the Phoenix sewer system---a system with over 7,200 km (4,500 miles) of pipeline that we modeled using existing databases and calibrated using field data.

Advantages of a Dynamic Model

We recommend this dynamic approach to sewer system modeling because it is no more costly or time-consuming to set up, yet provides accuracy advantages that cannot be matched by software using the static method. While static models are more conservative, the accuracy of the dynamic model allows your staff to set safety standards and make decisions, rather than relying on the software.

In order to provide you with specific information that will increase the effectiveness your planning and maintenance programs, Pipedream© has built-in flexibility and problem-solving efficiency that creates a custom-fit modeling tool that you can really use to meet present program objectives and achieve future goals. Pipedream© is accurate, reliable, easy-to-use, and very competitively priced. Where other packages might charge on a per-node basis, ours is a one-package system that can model unlimited line segments and pump stations.

The Modules

Pipedream© is comprised of three basic modules: the SSES Database Module, the Hydraulic Modeling Module, and the O&M/Rehab Module. These modules work interactively, allowing you to evaluate the entire sewer system or any specific set of data. With this one computer package, you can balance costs against your need to maintain and improve your system. Pipedream© allows you to control the overall system instead of simply reacting to the latest problems.

The first module incorporates inflow and infiltration data collected during I/I Investigations.

The SSES Module is a database that:

Evaluates the existing condition of each manhole structure, based on manhole inspection data and quantified I/I under specified rainfall conditions.

Evaluates pipe condition based on visual inspection data and establishes priority for follow-up television inspection.

Analyzes results of smoke testing activities and quantified I/I under specified rainfall conditions.

Compiles data from television inspection field reports and establishes a relational database for maintenance and capital improvements planning.

Uses building inspection data to evaluate impact of I/I from the private-sector such as downspouts, driveway drains, and sump pumps that discharge stormwater into the sanitary sewer system.

Confirms sources of I/I identified during dyed-water tests that discharge directly to the sanitary sewer system.

Provides a wide range of output reports from each of these program submodules.

Defects recorded in the SSES database can then be used for hydraulic modeling.

The Hydraulic Modeling Module:

Creates a model from physical parameters of the collection system.

Evaluates the hydraulic capacity of each pipe segment.

Analyzes hydraulic performance of the system by flows imposed on it.

Evaluates impact of inflow, infiltration, future growth, and industrial users.

Routes flows under dynamic conditions and simulates "real time" flow conditions.

Specifies relief and/or replacement sewer requirements when flow conditions exceed existing pipe capacity.

Performs hydraulic gradient analyses where moderate surcharge conditions occur and may be tolerable.

Interfaces with AutoCAD and other GIS information systems.

Dynamically models flow through the entire sewer system and produces hydrographs at any line segment in the system at any point in time.

Dynamically models flows traveling through the sewer system, lift and pump stations, split flows, time delays, major users and land usage.

The O&M Module:

is designed to help provide the operations and maintenance services needed to maintain the sewer systems by helping them to:

Evaluate system requirements for maintenance from the Database Management Program.

Schedule daily, weekly, monthly, and annual maintenance work orders.

Monitor performance of all maintenance activities performed on the collection system and maintain an updated hydraulic model.

Prepare summary reports.

Monitor extent and frequency of emergency repairs.

Automatically update the Database Management and Hydraulic Modeling Program as maintenance is performed.
