Control and Information Systems
Hazen and Sawyer is recognized as a leader in the design and implementation of integrated instrumentation, process control, remote telemetry and utility information systems in the rapidly advancing field of computer control and data communications.
Beyond traditional process control systems, Hazen and Sawyer has completed a number of utility operation assessments, and subsequently developed and implemented fully-integrated utility information system networks to assist in streamlining operations. Projects include department-wide local area network/wide area network implementation, laboratory and facilities management information systems, software and database consolidation and standardization, and automated reference manuals.
Successful control systems are easy to use, when appropriately matched to the specific application hardware and software. We keep this critical requirement in the forefront as we strive to design simple and highly reliable systems that are tailored to meet an individual client’s needs. Reliability is achieved through the following:
- Selection of proven equipment components
- Use of standard “open architecture” hardware and software products
- Surge and lightning protection
- Fiber optics
- Design of proper plant grounding systems
- Elimination of harmonics and noise
- Intensive “hands-on” training
In addition to understanding water and wastewater processes and their monitoring requirements, our instrumentation and control staff members are trained in the use of human-machine interface (HMI) and other widely used software (such as Microsoft Office, SQL Server, etc.), and have in-depth practical experience in the application of this software in the utility environment.
Our extensive experience in this area provides two distinct advantages: the ability to effectively communicate with system integrators, and most importantly, the skill to develop HMI displays, databases and easy-to-use information reporting systems tailored to meet a client’s specific needs and budgetary requirements, without relying on proprietary products or third parties for future support. In all our instrumentation and control projects, we adopt a team approach, in which C&I users, designers, and system vendors work together to produce a well-functioning system.
