Rusting. Blistering. Cracking. Peeling. Pitting. Chalking. Delaminating.
These words may be all too familiar if you’re responsible for keeping a wastewater treatment plant up and running. Yet the harsh environment surrounding this crucial infrastructure can pack a corrosive punch. But you can proactively prevent the deterioration of wastewater pipes, tanks and buildings. A protective coating evaluation is where to start.
On a nationwide scale, corrosion is a big problem. The price tag to prevent and fix damage to concrete, metals and other materials in wastewater treatment facilities is estimated at tens of billions of dollars a year.
Corrosion can seriously affect your community’s infrastructure. Not only are rusted pipes and pitted concrete unsightly, but they can also cause danger to public health, damage the environment and disrupt your community’s budget. Pardon the pun, but corrosion can eat into the lifecycle of your valuable infrastructure. It can cost taxpayers money that’s better spent elsewhere. And talk about sleepless nights: corrosion can contribute to problems that cause unscheduled shutdowns and emergency repairs.
The process of selecting, applying and maintaining protective coatings can be complex. It’s crucial to pay attention to project details such as surface preparation, coatings specifications, structural appurtenances, process coordination, industry standards and containment challenges.
But you don’t have to go it alone. Be proactive and schedule a coatings evaluation and inspection by a qualified consultant. With their help, you can design a plan to protect your wastewater assets. Proper and timely coating evaluations are a cost-effective way to extend your equipment lifecycle and maximize your budget dollars.
Schedule a conditions assessment to evaluate existing protective coatings and determine their remaining lifespan. If any immediate repairs are necessary, perform those repairs as soon as possible. A conditions assessment can also help you plan ahead: keep track of potential challenges so you and your ratepayers can budget for long-range planned maintenance. If you prioritize one repair over another, areas of isolated but severe corrosion can be repaired before the entire structure needs total rehabilitation.
Add future maintenance costs to your community’s capital improvement plan (CIP). Maintenance planning budgeted over a multi-year schedule can save thousands of dollars compared to the cost of complete rehabilitation.
Now is the time to be proactive to maintain your wastewater treatment facility. By scheduling a protective coatings evaluation, you’ll know which parts of your system are working to combat corrosion and which ones may need attention. Use this knowledge to make informed, strategic decisions to prioritize maintenance needs. When you ensure that protective coatings are doing their job, you’ll help maximize your community’s tax dollars as well as your wastewater system’s efficiency, safety, life span and ROI.
