We recently completed a surge analysis on an existing 60 km long steel and pre-stressed concrete gravity pipeline in South Africa. Although the pipeline has not suffered recent failures, we found during leak detection inspections that operational changes (opening and closing of valves) were performed very rapidly and we were concerned that this operating approach might be causing pressure transients and long term damage to the pipeline. We performed field measurements to capture data which we used to verify certain system parameters and calibrate the SURGE 2010 model. The calibrated model was then used to assess a number of operational scenarios to determine the impact of operational changes on the magnitude of pressure surges.
I was very pleased with the good correlation that was achieved between the measured and modeled data under steady state and dynamic conditions. It is definitely a compliment to the accuracy of the modeling software and gives us good confidence for future applications.

“I wanted to let you know that our client at the 15,000 acre historic park project completed final testing at the end of March following construction of improvements based on our analysis/report and design. The flow and pressure tests at representative locations throughout the park showed significant improvements in the pressure transients. One example: where we recorded with digital gauges a swing from 139 psi peak to a 38.5 low following shutdown of a hydrant flow in our original test, the recent final test resulted in 90 psi peak to 80 psi low. We really appreciated your and your team’s contribution with the surge modeling, analysis and recommendations.”

We've been working with KYPIPE for the past 2 years; both their programs PIPE and SURGE are excellent tools and have been of great help to us.
We use SURGE to help our clients select adequate surge protection devices (air valves, surge vessels, surge anticipation control valves, active check valves) and PIPE -not so frequently- to verify some designs. We also sell the program locally, we include it in our products presentations and for specific clients we give a SURGE talk that involves the program itself and the surge protection products.
You will not find better programs in the market, both PIPE and SURGE are leaders worldwide (the top hydraulic consultant company in Argentina works with SURGE). Their technical assistance is excellent and the have a lot of experience in water projects.

I just wanted to express my thanks for the patience and assistance everyone has exhibited and provided as I struggled through a "bad computer", and ultimately setting up this model. I worked with the client through extended field-testing and calibration work this summer, and feel pretty good about what we developed.
In particular Bill, I know that you were "at the center of the hurricane" as you worked to assist me this year. You exhibited a deep understanding of both water systems and hydraulic modeling, which makes your counsel both credible and useful. I hope you'll accept my thanks for the time you spent on this project.

I found PIPE2000 to be extremely intuitive and easy to use. If one understands the principles of hydraulic analysis in looped distribution systems, then figuring out how to use this software should not be difficult. Nice work, guys. KYPIPE is the standard to which all competitors are measured.
We use the software for fire flow analysis on 90% of our commercial sited development projects subject to regulation by the City of Austin Fire Department. We typically model peak fire demand for the buildings to ensure that the system can deliver the required flows.

We are currently using the software to model an entire pressure sanitary sewer system for the Town of Chapin, SC (near Columbia). This model will allow us to quickly analyze the Town's system and design its improvements. The software is working great and provides quick data entry and feedback on various design options. We have used it on many other projects to model both water and sanitary sewer systems and have been pleased with the results.
I.C. Thomasson Assoc, Inc. has used KyPipe or Pipe 2000 for hydraulic analysis of the chilled water distribution system on numerous projects including the following:
Tennessee Tech University
University of Memphis
Western Kentucky University
Nashville Thermal Transfer Corporation
Middle Tennessee University
East Tennessee State University
All of these are large distribution systems serving a central plant with multiple buildings connected. The model has been used to study constant flow systems and variable flow systems with pumping arrangements including primary/secondary and distributed pumping. Pipe2000 has been flexible enough to allow me model pumps in a number of different ways. Technical support has always been excellent. The latest versions of the program have such improved graphics for easy data input that I can model an entire system in a very short time.

We find ourselves using our PIPE2000 water model on a regular basis here in the City of Lawton (a Municipality), Oklahoma. With the aid of our PIPE2000 model, we were able to manipulate our systems to be able to maintain water supply during this relocation process at satisfactory pressure level this fall. ... Our distribution system behaved exactly as the model predicted.

Thank-you very much for the prompt and courteous reply. It is very much appreciated and VERY rare!
One project that [Pipe2000] was essential for was a cooling tower pump, piping design we did for service to four 200 ton water chillers . . . the modeling software allowed us to design without much refit . . . The software is easy to use and your support was very good. We will continue to use it in the future.
Omnova Solutions, Inc.
We have used your software for almost every project. The biggest one is project Tiel-west . . . For this project we have used the software for determining the diameter, the working point of the pumps for ten pump stations and water hammering in the system.
Pipe2000/KYPIPE was used to . . . determine the most cost effective remedy . . . which saved us in the order of NZ$100 000 (US$61 000) dollars - and this was just in one instance! . . . Overall - the modelling (in my view) has been very worthwhile! Over the years I have found your local agent (Stewart Sargent) along with several of your own staff members to be very helpful and responses to my queries would be very prompt despite the miles (and time zones) that separate our 2 countries.
