Irrigation Pipeline POLLUTANTS ADDRESSED: Nutrients and Organics, Salinity, Sediments
DESCRIPTION: An irrigation pipeline, consisting of pipes (of various materials), pumps, valves, and other appurtenance, allows the transfer of irrigation water underground rather than through open canals or ditches.
POTENTIAL TREATMENT AREAS: Agricultural lands Developed lands ALTERNATIVE MANAGEMENT MEASURES: Irrigation, Drip Irrigation, Sprinkler
LOAD REDUCTION MECHANISM: Nutrients/Organics Management - An underground pipeline confines irrigation water, controlling the spread of nutrients and organic pollutants.
PERMITTING REQUIREMENTS: None
Salinity Reduction - - An underground pipeline confines irrigation water, controlling the spread of salts.
Contact county regional flood control district.
Sediment Reduction – By reducing overground flows of irrigation water, an irrigation pipeline reduces soil erosion, thus reducing sediment transport. LAND USE CLASSIFICATION: Agricultural lands ADDITIONAL BENEFITS: An irrigation pipeline reduces water loss and protects water quality.

PLANNING AND IMPLEMENTATION: The design and installation of an irrigation system requires consideration of numerous variables, including the size of the area to be irrigated, the water requirements of the crops, the frequency of irrigation, optimal pump placement, energy costs for pump operation, maintenance requirements, and cost. Consultation with an irrigation engineer is recommended.
