Utility Systems, Science and Software, Inc. (US3), was founded in 2002 as a specialty technical engineering service company with its headquarters located in Santa Ana, California and Service and Engineering Facilities in San Diego, Sacramento, Salinas and Knoxville.

US3 engineers and technical personnel have applied advanced instrumentation system technology to water/waste water open channel flow monitoring, pipeline evaluation, engineering and data analysis, all coupled with the power of the internet.

This unique integrated systems approach allows the company to bring greater insight and intelligence gathering information about the water and waste water system performance to our clients, and in turn to support the fulfillment of their commitments to manage and obtain cost efficient designs, operations, and maintenance of these systems.

One of our main goals, directly from our business plan, is to provide our customers with the best professional engineering, technician, and software programming personnel available.

To accomplish this, we at US3 consider our employees and prospective employees to be our most valuable asset.

Therefore we have dedicated ourselves, by making it our primary goal, to search out, recruit, qualify with proper training, and hire the best employees fit for the tasks our customers require.

We aim for all this in the hopes of developing better long standing relationships with our clients to nurture future growth and development as well as mutual profitability.

Utility Systems Science and Software principles have installed and integrated hundreds of Flow Monitoring Systems for both fresh and waste water systems all over the world.

Today millions of people from cities, counties and industries depend on our systems to both monitor and control their infrastructure reliably every minute of every day.

It would be difficult for you to travel in the USA, from the North Slope of Alaska to Mexico, Pennsylvania to Hawaii (North, South, East and West) and not, in some way, have used our systems either directly or indirectly.

This level of accuracy and reliability is what your customers should expect in from our industry.

Seen here is the Port of Long Beach, International Transportation Terminal Receiving Yard, Pier J.

The Port relied on antiquated analog systems comprised of walkie-talkies, push buttons and the good old method of "look out!" to manage the hundreds of trains that pass through each day.

The Port averaged several longshoreman deaths each year as the system continued to worsen.

Now the US Government is thrilled with their new life saving toy!

We installed 18 highly sophisticated lighted panels which direct the inbound and outbound freight trains to the proper locations throughout this massive port yard. Each panel weighs roughly 400 pounds and stands about 12'.

In HawaIi, US3 engineers and technical personnel have applied advanced instrumentation system technology to water and waste water open channel flow monitoring, pipeline evaluation, engineering, and data analysis, all coupled to the power of the internet.

This unique integrated systems approach allows the company to bring greater insight and intelligence gathering information about the water and waste water system performance of our clients, and in turn to support the fulfillment of their commitment to manage and cost effectively design, operate, and maintain these systems.

As an Authorized Solution Provider, US3 and Marsh-McBirney have joined together to provide the Department of Environmental Services with a "Total Meter Solution" as an option to further enhance the RFP specifications.

The City of San Diego has a limit on how many gallons per minute of rain runoff may enter the sewer system from the Zoo & Tank System.

US3 placed meters at critical points along the water's path to accurately measure / quantify that crucial amount.

That data is then wirelessly transmitted back to the City and Zoo's Central Control Center.

Massive fines may be imposed if the Zoo discharges over the maximum allowed!

US3 has equipped the Zoo with an equalization tank with capacity of over 1 million gallons.

The purpose of the control system is to assist the Zoo with meeting compliance to their sanitary discharge permit and save them money on heavy fines.
