This study aims to present the results of the implementation of the model of joint trench for designing facilities of urban infrastructure in a Brazilian Technological Park (Sapiens Parque), using concepts related to planning and urban cadastre, sustainability and resource utilization, especially with focus on safety during construction, maintenance, operation and expansion thereof. The model proposes to replace the individualized construction of natural gas pipeline, potable water, firefighting system, telephone, cable TV, data, power - low and medium voltage and public illumination systems that encompasses all of these facilities in an only trench in the sidewalk, and the deployment of these may also occur in the same period, or if necessary, at different times, thus creating flexibility to the proposed system. The model also proposes the use of bike lane to implementation of sewage facilities, high-pressure pipelines and main water, and attachment a system for collecting rainwater aligned with the sustainability criteria, since that collects, stores and filters the water from the rains. The security and integrity of facilities due to the operational interface between the dealers and third parties is ensured by the design of bay in reinforced concrete, designed by the concept of "fail-safe device", derived from the Toyota Production System. The joint trench model was designed in a perspective of sustainability and technological innovation for your future use in the new design of power supply, through the concept of "Smart Grid Systems” with the use of transmission and distribution electricity in order bidirectional model for decentralized power generation through cogeneration systems to natural gas.
