HMT Engineering & Surveying has been retained by New Braunfels Utilities to develop an updated GIS database of all sewer manholes and water valves within their system. The data will be closely tied to the pavement management database to enable the City and NBU to better manage their assets. HMT responsibilities include using survey grade equipment to locate the x, y, z position of all manholes and valves. Additional field investigations will be made to determine manhole inverts and conditions. All the data collected will be entered into a GIS database. It is estimated that approximately 6500 manholes and 8000 water valves will be located and submitted to the database.
