Task One: The City of Leander is poised to make major investments for raw water supplies with the construction of the Brushy Creek Regional Utility Authority (BCRUA) Deep Water Intake on the main channel of the Colorado River in Lake Travis in order to supply raw water to the Leander Sandy Creek Water Treatment Plant and the BCRUA Water Treatment Plant. The City of Leander previously relied on Round Rock’s 2005 study titled Lake Travis Raw Water Supply and its recommendation of securing long range water supplies from Lake Travis as the most cost-effective means of securing adequate water supplies for the ultimate build-out of Leander.
Due to the age of that study, improvements in technology, development of large groundwater supply districts, etc., the City of Leander seeks the services of a qualified engineering firm to provide professional services for an updated water supply study as the basis for determining the most cost-effective method(s) of securing water supply(s) for Leander’s full development and build-out.
Task One Scope: A written report including but not limited to evaluations of the costs, capacities, curtailments, longevity of available alternatives for raw water and/or finished water supplies via the proposed BCRUA Deep Water Intake in Lake Travis, groundwater from the Carrizo-Wilcox aquifer, surface water supplies from Lake Grainger, Lake Georgetown, and/or Lake Belton, increased capacity of the Sandy Creek WTP raw water barge, interlocal agreement(s) with the City of Austin and/or other communities, and local or nearby groundwater well fields through the full build-out and development within Leander’s city limits and extraterritorial jurisdiction and projected long-term treatment and wheeling of raw water supplies from Lake Travis for the City of Liberty Hill and City of Georgetown.
Task Two: The selected qualified engineering firm will provide professional services to comply with U.S. Senate Bill 3021, America’s Water Infrastructure Act of 2018 (AWIA). The general scope includes a comprehensive assessment (Assessment) of the risks to, and the resilience of, the City of Leander’s drinking water system, and development of an Emergency Response Plan (ERP) that incorporates the findings of the Assessment, in compliance with all requirements of the AWIA. The U.S. Environmental Protection Agency (U.S. EPA) requires certification of the completion of the Assessment by December 31, 2020, and of the ERP by June 30, 2021. The selected firm must be able to meet these deadlines.
Task Two Scope: A written report detailing the assessment of risks to, and resilience of, all components of the water system, including:
1. The risk to the system from malevolent acts and natural hazards;
2. The resilience of the pipes and constructed conveyances, physical barriers, source water, water collection and intake, pretreatment, treatment, storage and distribution facilities, electronic, computer, or other automated systems (including the security of such systems) which are utilized by the system;
3. The monitoring practices of the system;
4. The financial infrastructure of the system;
5. The use, storage, or handling of various chemicals by the system;
6. The operation and maintenance of the system; and
7. An evaluation of the capital and operation needs for risk and resilience management of the system.
A written ERP that incorporates the findings of the assessment and includes:
1. Strategies and resources to improve the resiliency of the system, including the physical security and cybersecurity of the system;
2. Plans and procedures that can be implemented, and identification of equipment that can be utilized, in the event of a malevolent act or natural hazard that threatens the ability of the water system to deliver safe drinking water;
3. Actions, procedures, and equipment which can obviate or significantly less the impact of a malevolent act or natural hazard on the public health and the safety and supply of drinking water provided to the community, including the development of alternative source of water options, relocation of water intakes and construction of flood protection barriers; and
4. Strategies that can be used to aid in the detection of malevolent acts or natural hazards that threaten the security or resilience of the system.
