FAQ Frequently Asked Questions


The following are the minimum system requirements for running each module.

• At least an Intel© Pentium class PC.
• Windows 7 Operating System
• Microsoft© Excel for generating reports
• Approximately 50 MB free hard disk space, plus additional space for the project files.
• At least 512 MB RAM.
• Color Graphics video with screen resolution of 1024 X 768 pixels display.

All Ensoftec software applications (with the exception of SWMSoftVA© and HydrologyVA©) use Microsot Jet 4.0 Database Engine and require Microsoft Data Access Components (MDAC) version 2.6 or higher, with MDAC 2.8 recommended. Microsoft Data Access Components (MDAC) is a set of software components used to access data from various data sources such as Microsoft Access and Microsoft SQL Server.

MDAC is included with a large number of applications such as Microsoft Access 2000, SQL Server and Windows operating systems such as Windows 98, Windows NT, Windows 2000, Windows XP. If your system does not already have MDAC installed, you need to download and install it from the Microsoft MDAC Web site. To check to see what version of MDAC is already installed on your system, use the MDAC Component Checker program provided by Microsoft.

We pride ourselves on our motto, “Designing high quality software accessible to all”. As engineers who have worked in the business for numerous years we understand the difficulties smaller companies have in affording some of the higher end products available in the market. Therefore, we set out to create software which would drastically reduce design time and effort without “breaking the bank.”

No. We have endeavored to make InletSoft, PipeSoft and CulvertSoft as user-friendly and easy to understand as possible. We have also included step-by-step help pages to guide you through the design process. It is important to note that Users should have some familiarity with the concepts of hydrology & hydraulics when using the software. If required we will provide on-site training at a negotiated rate.

Ensoftec offers users three types of licenses.

SINGLE LICENSE - Single license holders may only install software on one (1) computer.
SITE LICENSE - Site license holders can install the Software on multiple computers at one business (physical address) location
ENTERPRISE LICENSE - Enterprise License holders can install the Software on multiple computers at any of their business locations as agreed between the Licensor and the Licensee).

For a detailed licensing agreement please send an email to

The software comes with step-by-step illustrated manuals which guide the User through installing the software to using its many features in a concise and easy-to-follow format. A PDF version of the User Manual is included in the package.

Most software is shipped within three to five business days of receiving the order. We ship priority mail USPS within the Continental United States, unless you specify otherwise. Contact if you required expedited shipping.

Open software may only be exchanged for the exact same item and may not be returned for refund. All expenses of transportation to and from Ensoftec, Inc. are the purchaser's responsibility. Unopened software may be returned for refund within 30 days of purchase less shipping and handling costs.

Customers of Ensoftec Inc. can subscribe to an Annual Maintenance Contract (AMC) for all Ensoftec's software products. This contract will provide the following software support:
1.    Maintenance updates
2.    Technical support
3.    Discounts for the newly released upgrades.

The price for the AMC is provided under the Buy Now option. Please contact for a detailed description of the AMC.

No! We decided not to put a cap on the number of inlets, pipes or culverts which may be designed in a project database. This is however dependent on the amount of system resources (such as memory, disk space) available on your computer.


This data is not required in the inlet design. However, this will be used in computing hydraulic grade line analysis of the storm drain system if linked to PipeSoft design software.

This information is for housekeeping only and is not used in the computations. The printouts will show this information.

This data is not required in the inlet design. However, the software compares the calculated spread with the allowable spread and gives a warning in the Remarks column of printout if allowable spread is exceeded.

LD-204 is an EXCEL spreadsheet and has been formatted for 7 pages of inlet data. The User has the flexibility to print only the required number of pages using File/Print option in Excel (Print Range). If more than 7 pages of inlet data were transferred to the LD-204 form, the User will need to format these additional pages before printing.


In tidewater areas and locations below sea level, the invert elevations will have negative numbers. PipeSoft accepts negative invert elevations as long as there is a positive slope of at least 0.0001 per cent.

PipeSoft computes the maximum capacity of a pipe based on pipe flowing full condition. This will facilitate the designer in the choice of pipe section. HGL analysis uses only partial flow or full flow conditions while computing head losses.

PipeSoft does not provide for reduction in area due to chamfers in rectangular sections. It is acknowledged that rectangular concrete sections will have chamfers (9 typical). This could result in a reduction in area ranging from 1% for a 10-ft x 10-ft section to 12.5% for a 3-ft x 3-ft section.

One way of dealing with this issue is to consider a proportionate reduction in width of the section. For example, for a rectangular section 6-ft x 4-ft, the net reduction in area due to chamfers is 5%. The analysis can be completed assuming a rectangular section 5.7-ft x 4-ft.

The skew is input to determine the bend losses in the pipe system while performing the hydraulic grade line analysis. In this analysis, the program identifies the skews of all incoming pipes at a junction and computes bend losses except for lateral pipes with inflow of 10 percent or less of the total flow through the junction.

VDOT Drainage Manual describes the method of computing Friction Slope (Equation 9.20 or Pipe Capacity Charts or Field's Wheel - Step 6, Page 9-50). PipeSoft uses Equation 9.20 of the Drainage Manual (Page 9-32). Computation of velocity (Step 8) is based on whether the pipe is flowing partially full or full. We have adopted a strict application of the Drainage Manual in this case. 

We will in due course, introduce options to develop pipe profiles, pipe descriptions and quantity estimates. The Users will be notified as and when these modules are ready.

Yes! Each outfall from a pipe system is analyzed separately for HGL computations. The User must input the Outfall/End Node and the Tailwater Elevation. The User then selects the Compute HGL toggle and PipeSoft calculates the hydraulic grade line for all the nodes in the specified pipe system. A new LD-347 form is created for each outfall analyzed.

PipeSoft has a built in check that the Total Discharge calculated for a pipe section cannot be less than the sum of all the discharges entering the pipe for the same storm event.


Results from CulvertSoft match with results from HDS-5 Calculator. The calculator can be downloaded from the FHWA web site at the link provided below:

Sample outputs are given below:

Results from HY-8 are in error as shown below:

The check discharge should match with the Design Discharge. This does not happen with HY-8 program.
