Harlingen Irrigation District No. 1 (Harlingen)

The Harlingen Irrigation District No. 1 office is located in the heart of Harlingen, Texas. The district boundary covers 56,114 acres of Cameron County.  They serve 38,025 acres of irrigated cropland and have an authorized water right for 39,574 acres.

The main pumping plant feeds out of the Rio Grande River near the city of Los Indios. The facility was built in the 1920's and has a current operating capacity of 470 cfs with a typical peak-pumping rate of 410 cfs. Within the district lies over 155 miles of pipeline and 57 miles of main canal, 55 re-lift pumping stations, and three storage reservoirs totaling a volume of 1380 acre-feet.

The district diverts 22,541 acres feet for domestic/municipal water users including the cities of Harlingen, Palm Valley, Rangerville, Primera, Combs and Los Indios.

Project 4 of US Pub.L 106-576    In the Harlingen Irrigation District Cameron #1 Irrigation District a project of meter installation and canal lining as identified in a proposal submitted to the Texas Water Development Board dated April 28, 2000.

Part 1: Meter Installation

The project proposes to install measurement devices at each of the numerous pump sites and at canal diversion points to monitor deliveries into particular irrigation lateral canals. These new measurement stations would be permanent installations for monitoring gross diversions through lateral canals and pipelines within the irrigation delivery system. The devices will be use in conjunction with telemetry equipment that will transmit the water flow information to the district office for real-time management and analysis.

Part 2: Canal Lining

This project proposes to line four canals totaling 8.92 miles of concrete to be overlain by a polyurethane/fabric composite material. The following canals are listed in order of greatest potential benefit:

Length (ft)
Citrus Garden
Wyrick + Lateral

The district foresees that savings will not only come from the elimination of water loss through seepage, but will in turn reduce associated pumping requirements and costs by increasing the operating head for gravity flow conditions. Other benefits may include increased on-farm efficiency due to the increased head pressure, and reducing travel time to a greater number of individual farms, lowering expense of the canal operation.
