IID serves as a raw water wholesaler, providing untreated Colorado River water to seven cities and two special districts, which then treat and distribute it to their residents.  IID annually apportions its available water supply to all water users using the criteria established in its Equitable Distribution Plan (http://www.iid.com/water/rules-and-regulations/equitable-distribution). Municipal users are apportioned first, and as such retain the highest level of water supply assurances.  IID manages municipal apportionments collectively; to the extent an individual municipal water user may exceed its annual apportionment, an increase is not necessary provided the cumulative uses of the municipal sector remain within the total municipal apportionment.  Should the cumulative uses exceed the quantified apportionment for all municipal users, IID will ensure that sufficient Colorado River supplies are available in accordance with the EDP to address all municipal water user demands for reasonable and beneficial uses that are implementing appropriate best management practices for this area.

For more information regarding Imperial Valley water supply, see Chapter 5: Supply, Demand and Water Budget of the Imperial Integrated Regional Water Management Plan.
