City of La Feria Water Distribution

SWG Engineering filed an application with Texas Water Development Board in 2011 to obtain funding for Water Distribution Improvements. Funding was obtained in the amount of $7,167,700.00, SWG designed and prepared contract and bidding documents for the installation of 46,600 LF of water line varying in sizes from 6” to 12”. The project consisted of:

  • 2,675 Water Meters (entire city)
  • 16,600 LF of 6” to 12” Water Lines for the West Colonias
  • 30,000 LF of 6 to 12” Water Lines for recently annexed areas east of La Feria
  • UV Water Treatment Plant
  • Replaced MCC (Motor Control Center) and added SCADA (Supervisory Control And Data Acquisition) systems


City of Donna 1 Million Gallon (MG) Elevated Storage Tank (EST)

From project planning to construction completion, which was concluded in 2020. This new EST has become a local landmark located adjacent to TxDOT Expressway 83, and bearing the City logo, as well as both local school team logos. The EST is especially significant to the City, in that it will be their only source of elevated water storage, as the only other existing EST in their system is currently scheduled for decommissioning. The project is innovative in that this specific EST is a sophisticated, state of the art system, remotely monitored through a central SCADA system, and an intrinsic component of the City’s water distribution system.

The SWSC 1 Million Gallon (MG) Elevated Storage Tank (EST)

This project was also a key component of SWSC’s new 8 MGD WTP (designed by SWG): a grant from USDA was procured by SWG to fund part of the expenses in construction of the WTP and the engineers were able to use the cost of construction of the EST as a partial match for grant requirements. This new EST has become a local landmark, located adjacent to TxDOT State Highway 364, and bearing the Water Supply Corporation’s logo.
