Background
Tucson Water Escalante Reservoir is a vital water management facility in Tucson, AZ, dedicated to providing sustainable water solutions for the local community. Focusing on conservation and efficient water distribution, the reservoir plays a crucial role in ensuring the availability of clean water resources for residents and businesses in the area.
Escalante Reservoir Rehabilitation Project Summary
The Escalante reservoir rehabilitation involved the installation of a geomembrane liner in the Escalante Reservoir to enhance its functionality. The reservoir was constructed without an existing liner, removing the need for demolition. To ensure long-term durability, the owner selected HypaFlex® (CSPE) 45 mil with the white side facing upwards, supported by a layer of 8 oz non-woven geotextile.
An 8-member crew executed the installation. Although the project extended slightly beyond the anticipated timeline, it was completed under budget.
Challenges & Results
One notable challenge encountered during the project was the absence of a termination attachment for the non-woven geotextile along the vertical walls. This issue necessitated the termination of the geotextile at the bridging bar connection, which required careful planning and precise execution to ensure stability and effectiveness. The project team had to meticulously design and implement a solution that would maintain the integrity of the geotextile and prevent any potential issues related to its attachment. This required a deep understanding of the materials involved and the environmental conditions they would face.
Despite this challenge, the project team demonstrated exceptional problem-solving skills and adaptability. They worked collaboratively to devise innovative solutions and ensure that the geotextile was securely terminated at the bridging bar connection. Their efforts were instrumental in overcoming this obstacle and achieving the project’s goals.
Both the general contractor and the owner expressed their satisfaction with the final results, highlighting the project’s successful execution. Their positive feedback underscored the significant contribution of the project to sustainable water management practices. The project’s success showcased the team’s commitment to delivering high-quality and environmentally responsible solutions, setting a benchmark for future projects in the field. The collaborative efforts and dedication of the team were key factors in the project’s overall success, reflecting their expertise and commitment to excellence.
