Wastewater Data Management System (WDMS) provides an information management system for wastewater facilities to manage sampling, laboratory results, reporting, and compliance tracking. It is designed for treatment plants, power plants, and chemical industries to use as a compliance system for managing water sampling programs required by environmental programs, such as the NPDES and pretreatment regulations.

The Work Flow

WDMS is a comprehensive and easy-to-use information management system that provides water dischargers with state-of-the-art technology to manage their water monitoring information.

The WDMS is designed with four major objectives in mind: regulatory compliance, cost and timesavings, flexibility to grow, and ease-of-use. Many critical regulatory components, such as DMR reporting and compliance evaluation required by the NPDES program are fully incorporated in the System. It allows the users to tailor the WDMS to meet their site-specific compliance strategies. The WDMS employs object-oriented technology that encapsulates all tedious and complicated DMR calculation procedures in an easy-to-use system.

The WDMS relieves the burden of record keeping and reporting so that you can concentrate more on compliance planning and engineering. A data exporting utility is also provided for transfer of critical environmental data to other computer systems for other uses.

Easy and Accurate Generation of DMR Reports
WDMS saves valuable resources by eliminating those required to analyze field monitoring data and tedious spreadsheet calculations, freeing up more valuable engineering time for compliance planning and evaluation. It consistently produces accurate DMR reports based on the user-selected calculation functions.

Ten commonly used regulatory calculation functions are available: Daily Minimum, Daily Maximum, 4-day average, 7-day average, 30-day average, 7-day geometric mean, 30-day geometric mean, 30-day minimum percent removal, 30-day average percent removal, and sum. All these calculation functions conform to regulatory requirements. WDMS gives you the flexibility to set the decimal points for each DMR parameter line based on the regulatory requirements pertaining to your facility, preventing stiff fines for inadvertent mistakes. DMR reports can be generated quickly and edited before submission to regulatory agencies. You can also export your DMR reports to electronic data files that are consistent with most regulatory requirements.

Efficient Data Acquisition and Central Management
WDMS gives you the flexibility to set up your own data input screen for speedy data entry. Importing your field and laboratory data from the spreadsheet programs of your choice to WDMS is quick and easy with an intuitive user interface. WDMS's object-oriented architecture allows the development of additional options to import monitoring data from other monitoring instruments or programs.

Central Tracking of Permit Information
WDMS manages your facility, discharge outfalls, and permit limit information. You can track permit renewal date and renewal remind date. Unlimited permit revisions can be maintained in the WDMS.

Sample Schedule, Chain of Custody & Bottle Label
Through the Sample Schedule module, WDMS allows you to track sample schedules and generate laboratory workload reports to remind laboratories of certain test procedures that need to be performed. The Chain of Custody report allows you to print out a complete history of custody pertaining to a given sample. The Bottle Label report lets you print out bottle labels with sample preservation descriptions for your samples.

Easy Checking of DMR Compliance Status
The WDMS provides graphical interface to help you easily to evaluate your DMR compliance status. Automatic warning displays alert you when there are any potential noncompliance events.

The Compliance Evaluation module allows you to tailor the compliance evaluation screen with your facility plot plan. Each DMR is automatically evaluated by the WDMS against the permit information stored in the database. You will be alerted of any potential noncompliance flagged by the WDMS with a "blinking red light" at the sample location shown on the facility plot plan. To further evaluate potential noncompliance, you can simply double click on the red light to zoom into the database to retrieve all the details.

Trend Analysis
The Trend Analysis module allows you to perform a discharge trend analysis in 3-dimensional graphics. You can export your graphical trend analysis charts to other Windows™ software for editing and presentation.

Key Features Wastewater discharge permits Sample schedule and analysis results Chain of custody of samples and bottle labels DMR calculation and printing (EPA 3320-1) Electronic DMR data filing Auto-processing of undetectable data (ND;<5) Permit and SNC violation flagging Discharge trend analysis in 3-D graphics Automatic unit conversions Data interface with external systems Integration of facility layout with database

Automatic Unit Conversion
WDMS has a unit conversion module that automatically converts all monitoring data to the appropriate unit for DMR reporting and data comparison.

Flexible Treatment of Not Detectable (ND) Data
The WDMS provides you with the flexibility to determine how the ND data from your samples is treated. There are four options for setting the ND data: (1) reporting limits, (2) instrument detection limits, (3) midpoint between zero and reporting/detection limits, or (4) excluding from reporting.

Advanced Security
Your sensitive environmental information is fully secure in the WDMS. You have total control of the data security by maintaining a list of authorized users, their logon passwords, and the ability to customize user access privileges at the menu screen level.

Context-Sensitive Help
Online system help is readily accessible when you need it. By pressing the "F1" key, you can quickly access on-line help for the currently displayed screen.

The Help facility also provides help on topics, key-word, and index searching.

Additional System Features
The WDMS is written in a user-friendly Windows™ environment with standard pull-down menus, making the use of the WDMS very intuitive. You can use the "repair the database" feature to recover lost information caused by external events. You can use the "EDI" module to import sample analysis data from external systems (such as Excel or LIMS), or to generate electronic DMRs in X.12 format for electronic submissions to the Agency. The Reporting module provides a comprehensive set of reports to help you easily review and print all the information stored in the database.
