CITY OF SONORA SONORA 201 East Main Sonora, Texas 76950-3798 325-387-2558 CITY OF SONORA FAX 325-387-5923 Public Report on the Lift Station Project - City of Sonora Background: On September 21, 2018, the City of Sonora experienced a severe flood event that caused significant damage to public infrastructure. One of the most critically affected facilities was the lift station located in the 900 block of North Water Street near the Interstate Service Road. This lift station, which plays a vital role in managing wastewater for a key commercial area of Sonora, was completely submerged during the flood, leading to extensive damage. Impact of the Flood Event: As a direct result of the flooding, the following damages occurred: Inlet Line Damage: The lines leading to the lift station sustained severe damage. Station Displacement: The force of the floodwaters shifted the lift station structure. Equipment Failure: The underground trash pumps were damaged, limiting operational capacity. Electrical System Destruction: The entire electrical panel controlling the lift station was destroyed. Since the flood, city employees (working in collaboration with external contractors) have managed to restore partial functionality to the lift station. Currently, the station is operating on a single trash pump without any backup system. This lack of redundancy has already resulted in multiple instances of complete system failure, posing an ongoing risk to the community. Importance of the Lift Station: This lift station serves a critical area of Sonora, including the majority of the city's motels, restaurants, and retail stores. Without a fully operational and reliable lift station, there is a significant risk of wastewater management failure, a catastrophic event that could disrupt essential services and public health. Need for Relocation: One of the primary challenges in fully repairing the lift station is its location within the floodway of the Dry Devils River. To prevent future flood-related failures, it is essential to relocate the lift station to higher ground. EHT Engineering Services, which has been working closely with the * CITY OF SONORA SONORA 201 East Main Sonora, Texas 76950-3798 325-387-2558 CITY OF SONORA FAX 325-387-5923 city, has confirmed the necessity of constructing a new lift station and demolishing the damaged one. Public Management has also been invoived in overseeing the project to ensure compliance with federal, state, and local guidelines. Project Costs and Funding: Initially, the project was planned to be funded through American Rescue Plan Act (ARPA) funds in the amount of $691,073.81. However, due to rising costs and the complexity of the relocation, the total estimated project cost has increased significantly. The contract for the project has been awarded to Darnell Construction at a total price of $1,793,432. This figure reflects the necessary work to build a new, more resilient lift station outside the flood-prone area and to demolish the existing damaged structure. It is important to note that this project cannot be analyzed with a single cost breakdown. Since its inception, multiple parties involved in assisting the City of Sonora have incurred significant expenses beyond the initial $700,000. These parties include: Public Management - Overseeing project management to ensure compliance with federal, state, and local guidelines, with incurred expenses totaling $12,250.00. EHT Engineering Services = Providing engineering expertise and construction oversight, with incurred expenses totaling $105,00.00. Darnell Construction - Selected as the lowest responsible bidder for the construction of the new lift station and relocation, with a proposed construction cost of $1,793,432. The total cost for the project is now $1,910,682.00, including administrative, engineering, and construction costs. Attached to this report are: 1. A detailed cost breakdown from Darnell Construction. 2. Photographs of the lift station in its current condition. 3. Images depicting the extent of flooding during the 2018 flood event. Conclusion: The City of Sonorais committed to addressing the risks posed by the damaged lift station and ensuring the reliability of wastewater management for our community. The relocation and * CITY OF SONORA SONORA 201 East Main Sonora, Texas 76950-3798 325-387-2558 CITY OF SONORA FAX 325-387-5923 reconstruction of this essential infrastructure will prevent future flood-related failures and protect the businesses and residents who rely on this service. The City, alongside EHT Engineering Services, Public Management, and Darnell Construction, is working diligently to complete this project efficiently and in compliance with all regulatory guidelines.
