HB 2114 amends the Texas Water Code to establish restrictions on engineering firms involved in the preparation of the state water plan or regional water plans. It stipulates that any engineering firm contracted or procured to assist in the preparation of these plans, or in assessing the feasibility of projects included in them, will be prohibited from participating in the construction of a reservoir under the same section. The measure is intended to prevent conflicts of interest in the planning and execution phases of water infrastructure projects.
