Dedicated Utility Zone
The utility component of the Trans Texas Corridor includes
infrastructure for the movement of oil and natural gas, water, electricity and data.
When completed, the utility component of the corridor will:
chances of pipeline damage and the related safety and environmental consequences. Third party contractors and individuals unaware of a pipeline’s presence cause the majority of these accidents. By placing pipelines in clearly designated utility zones, the likelihood of such incidents is greatly
efficiency of pipeline product movement. Existing systems are irregularly placed, cover short distances and carry relatively low volumes.
additional capacity for electrical transmission systems. Limitations in existing transmission systems have jeopardized service, affected consumer choice of providers and limited
the transfer of vitally needed water over long distances. If Gulf of Mexico desalination systems are developed, the corridor system could carry fresh water to areas of Texas desperately needing this vital natural resource.
cost-effectiveness of providing advanced telecommunications and data transmission to all areas of the state.
The existing Texas petroleum and petroleum product pipeline infrastructure
than 250,000 miles of oil and natural gas pipelines. Some of these lines traverse proposed corridor
volume needs for natural gas or petroleum product delivery.
interstate connectivity on major distribution systems.
Has the right
of eminent domain for utility and common carrier pipelines. Some lines are permitted within TxDOT rights of way.
Existing water line infrastructure
Has more than
1,200 water conveyance systems with little interconnectivity.
groundwater sources throughout the state. These supply 51 percent of Texas’ demands.
surface water reservoirs, primarily in East Texas. These supply the balance of the state’s water needs.
Electrical and data transmission systems
electrical transmission systems meet Texas’ needs, but future demand is expected to exceed capacity.
vast majority of Texans have ready access to basic communication services, access to advanced telecommunications and data transmission services is necessary for economic
development and participation in the global economy.
of industrial sites and other businesses is driven by the presence of quality data transmission infrastructure. A
recent Public Utility Commission report concluded that agricultural reliance on electronic commerce is expected to approach $70 billion in 2003.
pipelines generate a high level of public concern, due to land-use issues and proximity to large populations. Placing pipelines in a dedicated utility zone traversing unpopulated
areas would help alleviate these concerns.
systems would need to be expanded to connect with the corridor.
More right of
way acquisition will be necessary to accommodate other facilities associated with these pipelines. These include compressor and pump stations, aboveground valve stations and above-ground storage facilities.
systems are irregularly placed around the state, cover short distances and carry relatively small volumes.
local and regional water authorities control existing systems.
long-distance water transfers from Gulf of Mexico desalination systems are discussed in the current Texas water plan, no construction plans have been developed.
in the existing transmission systems have jeopardized service, affected market participants’ choice of providers and limited market transactions.
Some parts of
the existing transmission systems are approaching load limits. From 1994 to 2001, while very few bulk transmission facilities were added to Texas’ transmission system, peak demand grew 24.6 percent.
Reliability Council of Texas reports that putting new electrical generation facilities on line may create
additional problems unless existing transmission systems are upgraded to accommodate increased loads.
competitive and innovative services are available only in densely populated areas.
providers have found capacity to move data to and from the Internet is insufficient in some areas.
technologies require significant investments to upgrade existing infrastructure or build new infrastructure.
Petroleum and petroleum product lines
specific bypass corridors for pipelines would reduce public apprehension regarding construction across private
property and near residential development.
issues would be clarified by conducting a survey of large operators.
designs within the corridor would require state agency permitting and regulatory oversight.
Even with the
state as owner, current pipeline operators could lease, operate and maintain the facility.
limited to operators, the dedicated utility zone would reduce, if not eliminate, pipeline incidents.
In the event
of an incident, damage would be limited or controlled within the utility zone.
from atmospheric conditions will be lessened if underground vault systems are used. Underground vaults can accommodate multiple pipelines, providing easier maintenance.
Design specifications for pipelines would vary depending on the number to be placed in a corridor segment. Providing corridor access would exponentially increase the capacity of pipeline
infrastructure in the state. Pipelines would have as many connections as needed. Other design recommendations include:
or gathering facilities located adjacent to corridor segments.
be placed above or below ground with as little as 12" clearance between other pipelines or underground structures.
Pipelines are an important transportation link in Texas. While
the corridor system would not preclude new pipeline construction
elsewhere, it would reduce the number of large transmission lines traversing heavily populated urban areas. Public opposition due
to land-use and restriction issues would be reduced by the use of
the corridor system. The state would retain the ability to determine that the pipelines are safe. Pipeline operators using the
corridor would reduce costs by replacing right of way acquisition with
lease and operating agreements.
While current water supply systems meet Texas’ needs, demand is expected to overcome the existing system by 2050. To accommodate a projected population growth from 21 million to 40 million in 2050, water lines along the corridor’s utility zone will help
meet anticipated demand.
As new water
sources are developed, including new impoundments, private sale of water to municipalities, authorities or private interests, and basin transfers, new water lines will be needed.
toward regional water supply systems will continue, with the corridor likely to be incorporated into future water plans.
future source is desalinated water from the Gulf of Mexico. The corridor would accommodate a network of pipelines to move those supplies inland.
Electrical transmission lines
new electrical generation facilities, substations and connectivity assets built to meet expected needs.
reliable connections between generating systems and electricity providers to ensure reliable power delivery for the future.
flexibility for changing electrical-system conditions, allowing interconnectivity to resolve such issues as
maintenance forced equipment outages, higher demands on systems and fuel shortages in generating facilities.
Development and design of high-voltage electrical transmission systems
conventional engineering, including transmission towers.
alternative technologies such as underground systems.
As each segment of the corridor is planned and constructed, the Electric Reliability Council of Texas should be consulted in
determining current and anticipated infrastructure needs.
From telephone service to high speed Internet connections,
reliable communication is an essential part of the economy and culture of Texas. Data transmission lines in the corridor would:
integral component of the statewide communications infrastructure.
flexibility, access and connectivity for evolving technologies in both rural and urban areas. This will ensure reliable,
efficient communication for citizens, businesses and government.
Make right of
way available for current and future telecommunications providers.
Design and development of data transmission systems must include provisions to supply reliable and affordable services to meet
growing demands, while remaining flexible enough to adapt to future technological advances. By partnering with telecommunications providers in the design and construction of the corridor,
competitive and modern communications systems can be made readily available to all Texans.
