Leaking Tank at Major Utility Company

Project Scope

Prolong the service life of a leaking tank for a utility company.

Challenge

At a remote location, a process water tank for a major utility company was leaking approximately 10,000 gallons of water per week. Environmental concerns required immediate action to be taken. Between extreme cold weather and a very limited down time, an applied coating was ruled unfeasible. A fast and cost effective solution for making the tank liquid tight was needed.

Solution

A flexible membrane liner from Witt Lining Systems was selected as the perfect solution. The liner was made in two sections and folded to easily fit through the manway. Because the liner was secured to the top of the tank versus glued or bonded to the tank, no extensive sand blasting or prep work was necessary. This greatly reduced the tank’s down time over using an applied coating or bonded lining. Daily high temperatures were ranging from 8o F to 30o F, but since Witt liners are not bonded to the tank and do not need to cure, only enough heat to keep the liner at 70o F inside the tank during installation was needed. Since no cure time is required, as soon as the liner was installed and in place it was ready to be put back into service, again saving down time for the customer.

Results

Despite the cold weather and snow, the entire installation was completed in under four days. The process tank was returned back into immediate service with no further reported leaks

Since 1972 we have been the industry leader in providing flexible PVC corrosion resistant liners. Flexible liners are a cost effective alternative to bonded Linings and coatings. Flexible PVC liners are used in plating tanks, chemical tanks, storage tanks, waste water treatment pits, secondary containment, cooling towers, pits, sumps, solar heated water storage tanks, or anywhere liquid containment or corrosion protection is desired.

Industries served include metal finishing, plating, anodizing, aerospace, oil and gas, mining, municipal water treatment, and food and agriculture. Witt offers a variety of materials such as Koroseal®, Spectra Blue® and Exceline®. Witt Lining Systems also offers alternatives to PVC, custom fabricating Teflon® , Kynar® PVDF , and XR-5® liners. Wiitt offers a variety of liner grades and thicknesses to suit your lining need. Links
