Sewer Inspection and Evaluation
Our History and Experience
Blair, Church & Flynn has been actively involved in the evaluation, rehabilitation and design of sewer pipelines for more than 50 years. Our clients have included dozens of municipalities and agencies throughout California. For just one of these clients, we have designed more than 30 sewer rehabilitation projects; with a total construction value of more than $40.0 million.
Yes, we're proud of our firm's experience and technical abilities, but it takes more than that to deliver a successful sewer evaluation and rehabilitation project. Frankly, clients keep coming back to our firm because we provide them with great infrastructure design and excellent service. And we do that by dedicating the best of our resources to a project, being responsive and prompt, and providing engineering services with an attitude that is positive, collaborative and centered on solutions.
Contact us today to inquire about our full range of sewer evaluation and rehabilitation services. We're confident that we can meet your needs and exceed your expectations.
You can't evaluate what you can't see, so we rely heavily on high-quality video inspection for sewer evaluation. In times of painfully tight budgets, it is more important than ever to prioritize video inspection efforts so your limited resources are used first where they provide the best value. So we study system maps and as-built records, system history, and sewer maintenance records. We interview sewer maintenance personnel. We perform hydraulic modeling and sulfide generation analyses. That work provides a foundation for video inspection efforts by allowing us to focus first on the areas that have the greatest potential to be in compromised condition.
Every bit of our video inspection imagery is reviewed by a registered civil engineer who is certified under the NASSCO Pipeline Assessment and Certification Program (PACP). We believe that the importance of sewer evaluation efforts demands the broad education and experience base of a registered professional engineer. That, and the careful use of PACP evaluation protocols, enables us to provide evaluation results that are objective, meaningful and consistent. Our sewer evaluation engineers understand pipe materials, even those that nobody uses anymore, and the processes that quietly work to damage sewer systems.
Some people think a typical engineer is a little nerdy, right? Strong on technical matters, but weak on communicating with "normal" people. That's OK, we're not offended. But the best sewer inspection and evaluation results in the world are lacking if they can't be communicated in a thorough, accurate, readable and usable manner. Our sewer evaluation engineers prepare reports that are thorough and technically accurate, yet painlessly readable, while providing sound and reliable information to support the tough administrative decision making processes that follow.
Careful planning and prioritization, detailed review and evaluation by a highly experienced registered civil engineer, and reporting that you can understand and rely on. These are key elements of our success with sewer inspection and evaluation efforts, and key elements of our clients' success with sewer rehabilitation programs.
Why is it Important?
Sewer evaluation and rehabilitation efforts are valuable because they keep you in compliance with the System Evaluation and Capacity Assurance Plan (SEACAP) and Capital Improvement Program (CIP) provisions of your Sewer System Management Plan (SSMP). Compliance keeps you off the regulatory radar and it helps you maintain the health of your sewer system.
But sewer evaluation and rehabilitation should also be considered a cost control measure. Why? Because when a destructive sewer failure occurs where a problem went undiscovered or remedial work was deferred, the cost to set it right can be horrific. The best way to control the cost of your evaluation and rehabilitation projects is to see that they are implemented on your terms.
Sewer systems are sneaky, and trouble there can progress quietly until the problem has developed to the point of failure. Unless we purposefully look for those danger zones, sewer service backups, wastewater overflows, or even a sewer main and street collapse, might be the first indication that something is not right. Here, the value of sewer evaluation and rehabilitation also embraces the protection of public safety.
Why is it Important?
From the personal standpoint of individuals charged with running a municipal sewer system, the value of sewer evaluation and rehabilitation also includes peace of mind. True peace of mind in sewer system management comes from having a complete understanding of system deficiencies, combined with the knowledge that a plan is in place and on schedule to remedy those deficiencies and prevent future occurrences. Nobody knows it when a sewer system is well managed; they only know when it is not.
Regulatory compliance and the maintenance of a healthy sewer system are perfectly good reasons to stay on top of the sewer evaluation and rehabilitation efforts envisioned in your SSMP. However, the true value of that work extends to include cost control, protection of public safety, and the peace of mind that accompanies a well managed sewer system. Don't count on the long term deferment of sewer evaluation efforts and sewer rehabilitation projects to provide real value for your sewer system.
