Water use permits are issued with a schedule of time in which the permit holder is to complete development of the permit. An Extension of Time allows a permit holder to request more time (beyond the original time schedule contained in the permit) in which to complete construction of the water system and/or to accomplish beneficial use of water to the full extent under the terms of the permit.
Water related projects often require multiple permits. Please see Common Water Related Projects for information on other permits that may be required to accomplish your project.
