Long Range Planning for System Rehabilitation and Improvementby W. Martin Roche, Construction and Maintenance Dep, Manager, Turlock, United States,
Abstract: The Turlock Irrigation District, located in the Central Valley of California, supplies irrigation water to 150,000 acres and electricity to over 60,000 customers. The District's irrigation service area is highly developed, and the system includes over 250 miles of main canals and laterals, most of which are lined. The District has developed a long range plan and program for irrigation system rehabilitation and betterment. Each year a five year capital work plan is updated and a detailed capital work plan for the next year is developed. Updating of the work plans involves a detailed inspection of the entire canal system and a reassessment of priorities. In recent years approximately $600,000 to $900,000 per year has been spent on irrigation system rehabilitation and improvements. Major capital improvements include gunite resurfacing of canals, drop structure rehabilitation and modification, canal lining and extension, earth resources and country road crossings. Future improvements include canal system automation and pump automation. Most of the work is accomplished with in-house resources. By establishing a long range plan for irrigation system rehabilitation and improvement, the Turlock Irrigation District has assured that limited financial and human resources will be expended where they will provide the most overall benefits.
