San Juan, Texas, USA

Water Conservation Project for Hidalgo County Irrigation District No. 2 in San Juan, Texas

Status: Completed


The District in 2007 extracted water directly from the Rio Grande into a settling basin via gravity canal, and then into a conveyance system of pipelines and  canals.  The  District covers was 64,828 acres and had 4,000 water accounts with 4,700 acres of irrigable farmland. The District irrigation water rights were 137,675 acre-feet (ac-ft) per year. In addition, the District held domestic, municipal and industrial water rights totaling 12,732 ac-ft per year including 2030 ac-ft per year for the municipality of San Juan. In 2007 the District No. 2  includes the I-18 pipeline, which serves an area  of  2,829 acres. The design flow capacity of I-18 was 35 cubic feet per second (cfs). However, due to its deteriorated condition, the District restricts the flow to 18 cfs.


The objective of the project was to increase water management efficiencies by replacing 2 miles of a water conveyance mortar-jointed concrete pipeline  in  order  to avoid water losses in the Hidalgo County Irrigation District No. 2, San Juan Texas.


The project scope consists in improvements to the irrigation system in the Hidalgo County Irrigation District No. 2. which includes the reconstruction of pipeline I-18 and construction  of a new concrete pipeline adjacent to the existing mortar- jointed concrete pipeline with rubber gasketed reinforced concrete pipeline.
