CITY OF SONORA SONORA 201 East Main Sonora, Texas 76950-3798 325-387-2558 CITY OF SONORA FAX 325-387-5923 WATER DISTRIBUTION SYSTEM IMPROVEMENT PLAN 03/18/2025 To Whom It May Concern: The City of Sonora has been actively addressing critical deficiencies in its water distribution system and infrastructure over the past year. This project is vital to improving essential city operations, safeguarding water resources, and ensuring financial sustainability for our community. Water Infrastructure Challenges: Sonora's water distribution system has been experiencing up to 55% water loss due to factors such as waterline fractures, outdated meter readings, and possible unauthorized use of water serviçes. A comprehensive study of the city's water infrastructure has confirmed the significant impact of this water loss, which not only strains city resources but also affects taxpayers by reducing the potential for revenue generation and financial stability. To address these challenges, the City Council has prioritized the following actions: dentifying and repairing water leaks and damaged lines. Upgrading water well locations and equipment for safer and efficient water production. Replacing outdated water meters across the city. Installing a fixed-base Advanced Metering Infrastructure (AMI) system to enable real- time monitoring of water usage and ensure more efficient management of water services. This comprehensive water improvement project is estimated to cost approximately $3.5 million. The City Council is fully committed to these initiatives, recognizing their importance for environmental protection, operational efficiency, and long-term financial stability. Feel free to contact Arturo Fuentes at (325) 387-2558 for further information.

Haul off City Meter Replacement This measure involves replacing the current residential and commercial meters and installing the Diehl AMI system to facilitate communication with all meters. The benefits include: Water Meters: High-accuracy flow measurements across extended-low, low, medium, and high flow rates No moving parts in both residential and commercial flow meters Reduced maintenance and operational costs for the water system Enhanced revenue from residential water meters, ensuring 20 years of accuracy Meter alerts, including notifications for leaks 20% new meter boxes and lids AM!: Lowered operations and maintenance costs Real-time access to customer billing data Enhanced customer service Billing Integration: Improved accuracy in billing, customer experience, and processing timeline A billing platform designed for future integrations Reduction in customer billing complaints This measure entails the replacement of the following quantities and sizes of water meters: The accounts/meters excluded from the scope are: Any meters not dentified by the City of Sonora The scope includes the provision of the following spare water meters: None Detailed Scope: (1,376) 5/8" X 3/4" Neptune meters (173) 1" Neptune meters (74) 1.5" Neptune meters (36) 2" Neptune meters (8): 3" Neptune meters (1,667) Neptune Cellular Endpoints (420) Meter Assemblies (420) Residential Meter Boxes Neptune Meter Data Management software 12 months of hosting for the MDM software Training for Diehl Meter Data Management software Leak Detection System Vac-Truck Solid-State Water Meters Ultrasonic meters employ solid-state technology within a compact, fully encapsulated, weatherproof, and UV-resistant housing, making them suitable for both residential and commercial applications. This electronic metering technology provides information such as flow rate and leak detection indications, along with data that is not typically accessible through traditional mechanical meters and registers. Additionally, electronic metering eliminates measurement errors caused by sand, suspended particles, and fluctuations in pressure. Solid state technology meter features: Extended low-flow rates compared to typical positive displacement meters, allowing registration of very low water flows. A simplified, one-piece electronic meter and register that are integral to the meter body and virtually maintenance-free. A sealed, non-removable meter and register designed to be tamper-proof. 20-year accuracy warranty for meters ranging from 5/8" to 1". 10-year accuracy warranty for meters of 1.5" and larger. All meters will utilize solid-state water meter technology. These meters comply with or surpass the latest revisions of AWWA Standard C701 and C702 Class II. Furthermore, the meters do not require a valve to meet these standards. Each meter undergoes performance testing to ensure compliance. ALL meters are approved to the latest NSF/ANSI Standard 61, Annex Fa and G standards. Solid-state technology meters adhere to the relevant sections of the 2015 revision of ANSI/AWWA Standard C-700 and C-710 concerning accuracy and pressure loss requirements. Additionally, the meters are compliant with ANSI/AWWA C715 standards and NSF/ANSI Standard 61, Annex F. and G, and have been tested according to AWWA standards. The solid-state technology meter includes an in-line connector for straightforward connection and installation of AMR/AMI endpoints. AMI - Advanced Metering Infrastructure This project will put all meters onto the Diehl IZAR AMI system. Advanced metering systems consist of cutting-edge electronic and digital hardware and software that integrate interval data measurement with continuously accessible remote communications. These systems facilitate the measurement of detailed, time-based information and enable frequent collection and transmission of this data to various stakeholders. Advanced Metering Infrastructure (AMI) typically refers to the comprehensive measurement and collection system, which includes meters located at the customer site, existing cellular communication networks linking the customer with the service provider- such as the City of Sonora-and data reception and management systems that make this information accessible to the service provider. AMI links smart water meters to advanced analytics, equipping the City of Sonora with all the necessary tools to enhance its utility management. Moreover, customer portals will enable water customers to monitor and manage their own water usage effectively.
