Irrigation Engineering
IRZ Consulting has collectively conducted nearly two thousand irrigation system design and evaluations. Each design and evaluation included a detailed testing of the existing irrigation system and
recommendations to improve the irrigation hardware and operation to achieve water and energy conservation. The energy saving from these projects ranged 20%
up to 50%. This work was done in Washington, Oregon, Idaho, California, and Nevada USA.
Recently provided engineering design and construction management for developing an 18,500 acres irrigation system in Oregon, USA. This system
consisted of 143 center pivots, an 8,000 horsepower river pumping station from the Columbia River, two booster stations totaling 6,000 horsepower, and over
13.5 miles of steel pipe consisting of 72, 54, 51, 48, 36 and 34 inches in diameter and 15.8 miles of PVC pipe from 21 to 6 inch in diameter.
Recently provided engineering design and construction management for a 25,000 acre irrigation system in Oregon, USA. This system consists of 250
center pivots, a 23,400 horsepower river pumping station from Columbia River, booster stations totalling 12,750 horsepower, and a network of pipelines, the
largest of which is 72 and 60 inches in diameter.
Recently completed engineering design and construction management for a 4,000 acre irrigation system in Washington, USA. This system consists
of 34 center pivots, a 5,000 horsepower river pumping station from the Columbia River, three booster stations totaling 2,400 horsepower, and nearly 29 miles of
pipelines, the largest of which is 42 inches in diameter.
Recently completed a feasibility study for development of a 4,500 acre irrigation system in Washington USA. This irrigation system consisted of 38 center
pivots, a river pumping station and three booster stations from the Columbia River.
Recently completed a feasibility study for development of a 14,700 acre irrigation system in Montana, USA. This irrigation system consisted of 127 center
pivots, a river and a booster pumping station totaling 12,000 horsepower from the Missouri River, and 37 miles of pipeline, the largest of which is 66 inches in
diameter.
Recently completed a feasibility study for a 16,000 acre irrigation system in Montana, USA. This irrigation system will consist of 123 center pivots, 95 miles of
pipeline, a river pumping station and booster stations totaling 20,250 horsepower.
Recently completed feasibility study for a 5,000 acre irrigation system in North Dakota, USA. This irrigation system will consist of 38 center pivots, a river pumping
station from Missouri River, and booster stations.
Recently completed engineering design for a 2,000 acre irrigation system in Montana, USA. This system will consist of 15 center pivots, and a river pumping station
from Missouri River.
Designed, provided the construction management for, and oversaw operation of a 10,000 acre irrigation project in Washington, USA. System consisted of
approximately 80 center pivots, a 16,000 horsepower river pumping station from Columbia River, and an extensive mainline network beginning with a 66 inch
diameter steel pipeline.
Currently IRZ is involved in developing a Regional Water Plan and all related engineering designs that meets the water needs of 4 municipalities, a group of 23 large
irrigators, an irrigation district, and the local Tribes' fish enhancement project. This cooperative effort is a new design concept involving construction of a new river
pumping station and 11 miles of 60 inch pipeline to expand the existing Phase-1 and Phase-2 of Project for enhancing fishery while maintaining the economic viability
of the local Irrigation Districts.
IRZ was awarded a contract by the U.S. Corps of Engineers and developed initial design and set of specifications for 24 large river pumping stations located in
Oregon and Washington State along the Columbia River. This work was to mitigate the potential effects of a Columbia River John Day Pool drawdown (river
fluctuation).
Conducted feasibility studies of serving 150,000 acres of farms with existing pumping stations along the Columbia River with two large canals running parallel to the
Columbia River one in Oregon and the other Washington State.
Designed and provided construction management for a 420 acre drip irrigated hardwood pulp plantation in Morrow County, Oregon, USA.
Designed and provided construction management for a 600 acre drip irrigated hardwood pulp plantation for in Benton County, Washington, USA.
Designed the mainline network for a 350 acre of micro-sprinkler irrigation system for apple and cherry orchard in Walla Walla County, Washington, USA.
Provided a cost/benefit analysis comparing an open canal system with a large buried pipeline to meet the irrigation need of the Stanfield Irrigation District, Stanfield,
Oregon, USA while enhancing river flow for fish enhancement. The study also identified water and energy conservation measures and the associated costs.
International Irrigation Projects
Designed and provided construction management for a 300 acre drip irrigated winter vegetable farm, Kingston, Jamaica.
Designed and provided construction management for a 1,000 acre winter vegetable farm, Kingston, Jamaica.
Worked to improve surface water irrigation distribution systems on a large sugar estate, Ledsema Sugar Estates, Jujay, Argentina.
Designed improvements for an existing irrigation system on approximately 2,000 acres, Williams Lake, British Columbia, Canada.
Designed an 80 acre-foot reservoir for storage of irrigation water, Agro 21 Corporation, Ltd., Kingston, Jamaica.
Designed improvements to an existing water supply canal system, including removal of obstacles in the main canal, expanding capacity of existing siphons, and
installation of control and measuring structures Kingston, Jamaica.
Conducted an investigation of the potential for irrigation and design of irrigation systems in the Kingdom of Jordan, Amman, Jordan.
Conducted an investigation of the opportunities for investment in agricultural production in the Kingdom of Saudi Arabia, Jeddah, Saudi Arabia.
Water Conservation Projects
Currently provide daily irrigation scheduling information through a computer network service. Farms using this service account for more than 350,000 acres in
Washington and Oregon USA, with water and energy savings ranging from 10% to 20%.
Currently provide a weekly irrigation scheduling and soil-moisture monitoring services for potatoes, corn, onion, mint, alfalfa, apple, poplar tree and others. Over 100,000 acres
were monitored in Washington and Oregon. Water savings ranged from 10% to 20%
Provided engineering services to develop an irrigation conservation program for the Hermiston Irrigation District in Hermiston, Oregon, USA. The District has
10,000 acres of land with large number of users and different cropping pattern. Built in 1908, it has a network of reservoir and open canals and it is in need of
upgrade to meet the increasing demand from farms, residential and instream uses. IRZ evaluated and made recommendation on ways to improve the water use
efficiency and the cost for each improvement. US Bureau of Reclamation and the District jointly fund the project.
In a jointly funded project for the West Extension Irrigation District in Irrigon, Oregon, USA and the Bonneville Power Administration, IRZ developed a
comprehensive conservation plan to meet the future water needs of the District while helping river flow for fish enhancement. The plan identified seepage losses in
the canal and laterals, proposed main canal rehabilitation, documented the amount of conserved water, prioritized conservation components, and identified costs
associated with each conservation measure.
Designed a pressurized system that converts lands from flood to a pressurized sprinkler system with a central pumping station for the Hermiston Irrigation District,
Hermiston, Oregon USA.
Has developed the Plan, and is currently conducting a five years pilot program of "Winter Artificial Recharge" project to cool the Umatilla River while enhancing the
flow. This project is sponsored by Oregon Water Coalition, Westland Irrigation District, and Columbia Water Trust.
Recently IRZ was involved in a team to conduct a feasibility study for exchange of water from Okanogan Irrigation District to enhance fishery in the Salmon Creek in
Washington State. IRZ was involved in design of a new 7,000 horsepower river station on the Okanogan River with 3.5 miles of 48 inch diameter pipeline. Included was identifying and implementing district-wide water conservation measures.
Acquired water rights and provided engineering design and upgrade of existing irrigation system for watering a wildlife refuge for the Confederated Tribes of
Umatilla.
