Water Processing

The mission of any fresh water supply agency is to conserve, protect, manage and enhance the water resources for the citizens through the appropriation and reallocation of the public waters.

This is the direct mission, but it comes with secondary responsibilities for quantifying existing water rights; monitoring water use; distributing water in accordance with court decrees; reviewing water availability for new subdivisions and condominiums; reviewing the construction and operation of dams; appropriating geothermal water; licensing and regulating well drillers and water rights surveyors; reviewing flood control projects; monitoring water resource data and records; and providing technical assistance to appropriate public and governmental agencies.

Major issues within water systems are: 1. Security and 2. Valve Maintenance

In a perfect world, a fiber optic cable would be installed alongside every major fresh water pipeline. That would provide the bandwidth for video security monitoring of strategic processing points, and facilitate SCADA reporting of improperly set valves.

However, considering the age of most water infrastructure, fiber optics is a future enhancement, and the most logical vehicle for implementing SCADA and area wide networks is wireless communications.

Frequency Spectrum Selection

While loud voices will call for the use of cheap, unlicensed spectrum, these bands are growing rapidly, and interference over the long term is likely to be a major headache.

The wiser investment in spectrum to support these networks are those which have been auctioned by the FCC, where the utility has control over their wireless links, and interference can be managed.

Considering the long term expectred lifetime of Water systems, this is a minor contributor to the annual lifetime cost.

Aurastar brings solid experience and expertise in the development of SCADA systems and Smart Grid distributed network technologies. This includes wireless engineering in a wide variety of frequency bands, with particular expertise in the acquisition and utilization of auctioned spectrum.

An Aurastar SCADA system has been monitoring and controlling eight substations that power eight high speed wind tunnels at Arnold AFB in Tullahoma, TN for many years.
