DataFlow Systems is responsible for the design, manufacturing, and service of the entire TAC II SCADA System product line. There

Exemption

Reason *

Attach documentation from the manufacturer certifying the vendor selected is the only distributor/dealer/contractor for the products or services in question and/or holds the

production, unique capability, copyrights, trademark, and/or patent to the item, and check the following applicable statement(s):

Patent, copyright or unique design restrictions. (Sole Source)

Proprietary rights in technical data and/or product formulations (e.g. cleaning compounds, lubricating oils, paint, etc.), which can only be determined through

extensive laboratory analysis and examination. (Sole Source)

Only producer, such as utility supplier or construction material supplier, that will meet the specialized needs of the department or perform the intended function.

(Sole Source)

Direct replacement parts, equipment or supplies that must be compatible with original equipment already installed but available only from the original equipment

manufacturer. Most manufacturers have more than one dealer or distributor for their products. When this is the case, competition between dealers and/or

distributors may be possible, eliminating the “sole or single source” restriction. (Single Source)

When tests and/or demonstrations of equipment, supplies, part, etc. under actual operating conditions reveal superior quality, performance, design or other

characteristics in a brand product(s), which is available from only one source. Testing must be performed as often as practical. (Single Source)

Purchases for a brand product are to be made from one selected supplier, even though there are other suppliers that provide similar products. Options, such as

pricing, availability, servicing, have been vetted and a supplier has been chosen that best meets the City’s needs. (Single Source)

Maintenance, repair services or warranty which require specialized test equipment, procedures, and technical expertise available only from the original

equipment manufacturer or authorized/licensed dealer/field service representative. (Single Source)

The part(s)/equipment are required to permit standardization and operating efficiencies within the organization and the parts and equipment are only available

thorough a sole or single source. If competition is available, the parts and equipment must be competed. For brand-specific items, quotes should still be

obtained. (Standardization)

Other: None or some of the above apply. Provide detailed justification below.

SOLE SOURCE LETTER

December 1, 2025

This letter is to provide notification that Data Flow Systems®, herein known as “Company” with corporate

offices located at 605 N. John Rodes Boulevard, Melbourne, FL 32934, is the sole creator, manufacturer and

marketer of a group of systems and products, including the TAC II SCADA System, as well as Remote Terminal

Units (RTUs), Telemetry Control Units (TCUs), Hyper SCADA Server (HSS), HyperTAC SCADA Software, and the

Symphony Pump & Flow Management® technology. The company is also the sole source provider for all

associated support, repairs, service, and training for each of these solutions.

The company has nine (9) issued patents globally including patents governing wastewater collection flow

management and techniques, fluid flow management system and associated methods, fluid flow management

through a wastewater level manipulation system and associated methods, liquid level determination system

and association methods, liquid level determination system, valve malfunctioning detection system for a

vacuum sewer and associated methods, Modbus simulation system and associated transfer methods, and

liquid-resistant control systems enclosure.

Further, the Company’s family of products are designed and manufactured to provide users with unique

qualities and functions for remote monitoring and control for water, wastewater, and stormwater utilities.

Users acquire trend data via the patented and proprietary HT4® software tool which issues “Alarms” and

“Alerts” that monitor specific operational parameters. All notifications provide information and resources

enabling effective, informed decision-making for corrective or preemptive action. The patented HT4 Mobile®

app is designed to have access to the software from the plant, field or office.

The patented Symphony Pump & Flow Management® technology coordinates the system-wide operation of

sewer lift stations for the purpose of reducing force main pressures and equalizing flow into a wastewater

treatment plant, which enables the ability to significantly reduce energy costs and provide a solution to daily

peak-flow issues

Among its portfolio, the Company is protected by the following US Patents: 8,594,851; 8,600,568; 8,983,667;

9,556,040; 8,340,929; 8,521,452; 8,228,190; 8,260,872 and 9,200,466. We hope this information will satisfy

your requirements and that it clearly demonstrates the special, patented, unique and proprietary features of

our systems.

Sincerely,

Corey Williams, P.E.
