CapdetWorks - Wastewater Treatment Plant Design/Costing
Accurate and rapid preliminary design and cost estimating for wastewater treatment plant construction projects are a worldwide priority. CapdetWorks is a preliminary design and costing program that eliminates the need for spreadsheet-based design algorithms that can be relatively inflexible and are often time-consuming to maintain.
The activated sludge design algorithms in CapdetWorks are based on the concepts of solids retention time and influent fractionation, and are consistent with published activated sludge dynamic models such as ASM1 and the algorithms published in Metcalf and Eddy (Wastewater Engineering: Treatment and Reuse, 4th Edition), the Water Research Commission (Theory, Design and Operation of Biological Nutrient Removal Activated Sludge, 1984), and Wentzel et al. (Biological excess phosphorus removal – steady state process design, 1990).
CapdetWorks uses a unit costing approach with an extensive costing database that accounts for the effects of inflation using cost indices. Our unit costs are carefully researched based on discussions with manufacturers, suppliers, and consultants.

Hydromantis is committed to the continued growth of CapdetWorks, incorporating the latest developments in wastewater process technology and model development. We are pleased to announce the release of CapdetWorks Version 2.5. New or updated features in Version 2.5 include:
Updated Equipment Cost Database:
Extensive research went into checking and obtaining updated costs for all of the equipment and unit costs that are required when designing wastewater treatment plants. Costs were obtained from suppliers and manufacturers throughout North America and were cross-checked using costing studies done by our own consulting group.
Version 2.5 has an updated reporting feature that allows users to export costing data, layout schematics, and process data into three different file formats, depending on the user's preference. The report can be created as a Microsoft Excel spreadsheet, a Rich Text Format document (which can be opened in most word processing programs including Microsoft Word) or simply as plain text.
Forgotten why you changed a particular parameter? Now you can record as much information as you like right in the CapdetWorks layout. Each parameter now has a “notes field” where you can record and review information as needed.
Many of the design algorithms for the existing unit processes were improved and updated, and the chemical specifications throughout the program have been made more consistent and clear. Additionally, the interface functionality has been updated to improve ease-of-use.
CapdetWorks helps you work more efficiently because you can quickly build numerous treatment alternatives and compare their relative costs. Simply define the wastewater influent, layout a treatment strategy, define the desired effluent quality, press the calculate button and CapdetWorks will design the plant and provide detailed costs to build, operate and maintain the facility.
- Of course there is also a vast amount of flexibility and power beyond this ease-of-use, such as:
- Fully interactive drag-and-drop user interface.
- 60-treatment processes covering the entire plant, including BNR and biosolids handling.
- Automatic calculation of unit process dimensions and equipment.
- You can override capability for many of the design results
- Create customizable cost databases for different geographic locations.
- User-definable cost indices or apply published industry indices.
- Supports multiple units of measurement (i.e.: SI, US units, etc.).
- Interactive sensitivity analysis — for analysis of design parameters.
CapdetWorks calculates all costs, including capital, operating and maintenance, for each treatment alternative. Designs are based on many of the wastewater characteristics, not just wastewater flow. This methodology offers a dramatic improvement over traditional empirical methods.
CapdetWorks uses well-accepted design algorithms to derive the required unit process designs; unit cost estimation techniques are used for a majority of the treatment processes.
CapdetWorks offers two different types of licensing packages to choose from, the single license and the network license. Both licenses are similar, except that the network license allows multiple users to concurrently use the program at one time. CapdetWorks is to be installed both on a server (NT, XP or 2000), and on the users' computers.
When you initially purchase a CapdetWorks license from us, you will automatically receive a full year of technical support and any upgrades that are released during that year period. Once your technical support and upgrade contract has expired, you may at that time renew your contract with us.
We also offer CapdetWorks, at a discounted price, to academic institutions. CapdetWorks is ideal for research and it is equally ideal for teaching purposes. With the functionality of our academic site license, multiple students can be taught simultaneously, giving the students a 'hands-on' experience of running a design and examining treatment alternatives.
