The following Software programs were written and developed by Professoranie Van Vuuren and his colleagues and students of the University of Pretoria. More Information and support on these Software Products can be found at www.sinotechcc.co.za

Aqua Hydraulics
The AQUA Hydraulic Utilities consists of an easy to use user friendly Life Cycle Costing program for the design of pipelines. All the programs were written in Visual Basic version 6.0 by Sinotech CC.
The user friendly program is a valuable and time saving tool with which Engineers can design a pipeline over the full life span taking into consideration all the costs. The program can design a gravity or pumping system with varying or fixed demands.
The program provides the engineer or designer with a tool to ensure that the design is the best solution for the complete design life of the system.

The program requires the user to enter the demands, design life, pipeline profile, pipeline characteristics, laying details, rates and costs. The program will determine the initial capital requirements the annual maintenance and operational costs and in the case of a pumping system the energy costs. The program provides a graphical representation of these costs as well as the hydraulic capacity of the ageing system. Tables with all the calculated results are also shown with the capability to export these to other Windows.

Developed by EPA’s Water Supply and Water Resources Division, EPANET is software that models water distribution piping systems. It is a Windows 95/98/NT/XP program that performs extended-period simulation of the hydraulic and water quality behavior within pressurized pipe networks.
Pipe networks consist of pipes, nodes (pipe junctions), pumps, valves, and storage tanks or reservoirs. EPANET tracks the flow of water in each pipe, the pressure at each node, the height of the water in each tank, and the concentration of a chemical species throughout the network during a simulation period. Chemical species, water age, source, and tracing can be simulated.

EPANET provides an integrated computer environment for editing network input data, running hydraulic and water quality simulations, and viewing the results in a variety of formats. These include color-coded network maps, data tables, time series graphs, and contour plots.
EPANET is public domain software that may be freely copied and distributed.
