Though no project can follow a "cook book" approach, there are many things we've learned over the years that form the basis of our initial thinking for reservoir rehabilitation projects. The critical and/or unique elements of this project are significant but not unusual. As noted above, we view reservoir projects as civil engineering designs with a hydraulic emphasis. If you don't get the hydraulics right, everything else falls apart. We take understanding existing hydraulics very seriously, and recognize it as and one of the most important aspects of a reservoir rehabilitation design. Our experienced structural team has successfully rehabilitated concrete tanks up to 21.5 MG. We have found what makes a reservoir project unique are the hydraulic considerations and ensuring water reliability and water quality. Items we address in our assessment of the pros and cons for each alternative include: 1. Hydraulic considerations. How does the reservoir function with the entire system? 2. How is flow distribution within the reservoir handled? 3. How is water quality assured by proper distribution and mixing over a continuous period? 4. How can we assure reservoir turnover to manage the "age of water"? 5. Access for operations and maintenance: How do we assure safe access, where do we locate new hatches, and how do we provide adequate ventilation and lighting? For example, BRADY strongly recommends that internal stainless steel stairs be installed to eliminate the need to scale a 20 to 30- foot ladder, no matter how many safety measures are provided. We strive to eliminate any way a person can be injured by entering a reservoir. 6. Overflow and drainage. Where does overflow discharge to? How is drainage of the reservoir satisfied? Designing for the City's 0&M personnel is a critical success factor and BRADY will work closely with the City's 0&M staff. Though it may be a functional solution to a problem a project is often considered a failure by the designers in hindsight if the needs of O&M are not thoroughly satisfied. In addition to the technical approach, a well thought out management approach is the other side of the balance beam. We know from our long history in the water business that schedule and budget compliance are critical success factors. We know the City has the public to answer to, and there is nothing worse than going over budget or long on schedule which means going back to the City Council. Making sure we don't go down this path begins with a clear understanding of the project's scope and the City's specific requirements, the assembly and commitment of an experienced team alongwith all necessary resources, establishment, monitoring, and maintenance of the project's deliverables within set parameters, which includes schedule and budget, and U RICHARD BRADY & ASSOCIATES, INC.
