The Well No. 6, Reservoir No. 1 does not have a cathodic protection system, while the newer Reservoir No. 2 does. Steel naturally reacts with water and oxygen, returning to its more stable chemical state of iron oxide. Cathodic protection extends the life of a steel water reservoir by providing a sacrificial anode within the reservoir.
The reservoir was built in 1991 and the interior hasn’t ever been recoated. Without previous cathodic protection, a new coat is needed.
* Initial projected costs were $62,000 for W 12.0 and $220,000 for W 13.0
