SCADA/Programmable Controls
ArcSine Engineering has considerable experience in planning and designing programmable systems for process monitoring and control. Most of ArcSine's process projects utilize programmable control, including programmable logic controllers (PLC's), remote terminal units (RTU's), personal computers (PC's) or larger platforms, and combinations of the elements above in supervisory control and data acquisition (SCADA) systems. Arcsine's projects include skillful integration of new controls with existing controls, with special attention to construction sequencing to maintain facility operation. Following are sample projects:
SAN FRANCISCO WATER SCADA SYSTEM
Field investigation, developed comprehensive points list, and prepared master planning documentation for 300 remote sites. Design of power, instrumentation and controls, and RTU's for 150 of the sites. Remote sites communicate with four central sites via telephone, radio, and satellite communications to provide total water system monitoring and remote control capability.

As part of a District-wide SCADA upgrade project covering 80 sites, wrote detailed requirements for soliciting design-and-build proposals from qualified systems vendors.
LIVERMORE-AMADOR VALLEY WATER MANAGEMENT AGENCY
Designed the programmable controls and SCADA system upgrades for 5,500-hp pumping station.
ZONE 7 WATER SYSTEM
In the Livermore, California, area in 2001 designed all local provisions for a water SCADA system covering approximately 30 remote sites plus two treatment plants. In addition to SCADA, the project included complete rehabilitation of treatment plant controls.
BELLA VISTA WATER DISTRICT
As part of the water filter plant expansion, designed plantwide PLC controls. Controls included dual, redundant controls communication link with 30 remote valve operators. For wells and pumping stations, designed PLC controls and performed programming and startup. Designed interfaces to ISDN telephone telemetry and provisions for future system-wide SCADA.
DELTA DIABLO SANITATION DISTRICT
For a new reclaimed water facility, designed plantwide PLC controls and integration with existing controls and networking.
BENICIA WASTEWATER TREATMENT PLANT
Designed plantwide distributed control system, complete.
MARIN HEADLANDS WATER SYSTEM
Designed water SCADA system.
CITY OF SUSANVILLE WATER/WASTEWATER SYSTEM
Prepared a SCADA conceptual design and documentation to solicit vendor design-and-build proposals.
SAN DIEGO NORTH CITY WATER RECLAMATION PLANT
Designed plantwide distributed controls, and assisted with startup and testing.
CITY OF BRENTWOOD TREATMENT PLANT
Designed an entirely new plantwide control system including PLC's in a dual-redundant hot standby configuration, plant SCADA system, and plantwide process communication network and local-area network. Included plan fiber-optic loop in a self-healing configuration. Provided for integration with future City facilities.
CITY OF BRENTWOOD WATER SYSTEM
As of 2001, design was underway for a 24-site water SCADA system, complete. The project included identifying and documenting the ultimate system, then optimizing the initial project to meet budgetary constraints.
PALMER CREEK COMMUNITY SERVICES DISTRICT
Designed water system PLC/PC-based control system, with remote monitoring and control capability.
SHASTA DAM FILTER PLANT
Designed plantwide PLC controls, modified and debugged PLC program.
NASA HIGH-PRESSURE AIR SYSTEM
