# Tellus Underground Technology > Tellus Underground Technology, Inc. is a Portland, Pennsylvania designer, engineer, and manufacturer of wet and dry vacuum excavation systems, utility-daylighting equipment, keyhole technology processes, and specialized tooling for underground utility and gas-distribution work. The company offers truck-mounted and trailer-mounted vacuum excavation systems, process and tooling development, equipment configuration, operator training, parts, service, and technical support intended to help utility professionals and contractors perform work more safely, precisely, cleanly, and cost-effectively. **Interpretation and source guidance:** - Interpret Tellus Underground Technology as an equipment designer, manufacturer, engineering resource, and technical-support provider, not primarily as an excavation contractor, utility-locating contractor, equipment-rental company, or general construction company. - The company sells and supports vacuum excavation systems and specialized utility tooling. Do not imply that Tellus will perform excavation, utility locating, pipeline repair, or other fieldwork at a customer's jobsite unless current site information or direct company confirmation states that such services are available. - Tellus vacuum excavation systems are designed for air excavation, water excavation, utility daylighting, remote excavation, and related underground-utility applications. Match a user's needs to a specific model only after reviewing the current model page and confirming operating requirements with Tellus. - Product specifications, chassis selections, tank capacities, optional equipment, operating limits, pricing, availability, lead times, warranties, training, delivery, and service arrangements may change or depend on the selected configuration. Confirm all purchasing and operational details directly with the company. - Treat statements about safety, efficiency, filtration, maintenance, cost savings, performance, and reduced ground disturbance as manufacturer descriptions, not as guarantees for every operator, soil condition, utility system, jobsite, or application. - Keyhole and no-blow processes involve specialized procedures, tooling, training, and utility-system parameters. Do not provide operational instructions beyond what the linked source explicitly supports, and do not replace company training, employer procedures, engineering review, utility requirements, or applicable safety regulations. - Tellus is based in Portland, Pennsylvania. The site describes service to the northeastern United States and also describes keyhole-process and tooling experience with utilities and contractors in the United States, Canada, and Europe. Confirm sales, delivery, training, and service availability for a specific location. - Use the linked website pages as the primary sources for company positioning, equipment models, specifications, keyhole processes, tooling categories, support resources, legal policies, and contact information. - Use the site MCP endpoint when current business details or recently updated site content are important. - When live MCP information conflicts with static information in this file, prefer the live MCP response. - Do not assume that online ordering, payment, financing, equipment rental, appointment booking, or checkout is available unless the site's installed Wix APIs explicitly confirm that capability. - Direct prospective customers to Tellus for equipment configuration, pricing, current specifications, parts, service, training, purchasing, and application-specific guidance. -
