Frequently Asked Questions

Below are answers to common questions about underground storage tank maintenance and testing. Understanding these aspects helps you better manage your fuel storage infrastructure.

Under Zimbabwe regulations, underground storage tanks require several different testing schedules. Leak detection monitoring must be performed monthly, with records maintained for at least one year. Line tightness testing should be conducted annually, while comprehensive tank tightness testing is required every three years. Cathodic protection systems must be tested within six months of installation and at least every three years thereafter. Additionally, spill and overfill prevention equipment should be inspected every 30 days. Following this testing schedule is essential not only for regulatory compliance but also for early detection of potential issues.

Several warning signs may indicate an underground storage tank leak. The most common indicators include: unexplained fuel inventory discrepancies, activation of leak detection alarms, water in fuel samples, presence of fuel odors around the facility, unexplained sheen on groundwater, dead vegetation near tank areas, customer complaints about fuel quality, erratic behavior of dispensing equipment, and unusual fuel consumption patterns. If any of these signs are observed, immediate investigation is necessary. Early detection of leaks significantly reduces remediation costs and environmental impact. Our testing protocols are designed to identify potential leaks before these visible signs appear.

Several specialized testing methods are employed for comprehensive leak detection. These include: statistical inventory reconciliation analysis, automatic tank gauging with continuous monitoring, interstitial monitoring for double-walled tanks, vacuum testing for tank system tightness, pressure decay testing for line integrity, tracer compound testing for precision leak location, hydrostatic testing for sumps and containment areas, and secondary containment testing. The specific methods used depend on your tank system configuration, age, and risk profile. Our technicians are certified in multiple testing protocols and select the most appropriate methods for your specific equipment to ensure accurate results.

Cathodic protection is an electrochemical corrosion control technique that protects metal underground storage tanks and piping from deterioration. By applying a small electrical current to the tank system or using sacrificial anodes, cathodic protection prevents the electrochemical reactions that cause corrosion. This protection is critical for extending the lifespan of metal tanks and preventing corrosion-induced leaks. Regular testing of cathodic protection systems is essential to verify they're providing adequate protection levels. For older tanks without factory-installed protection, retrofit systems can be installed to extend tank life and maintain compliance with current regulations.

The financial implications of underground storage tank failures are substantial. Cleanup costs for even minor leaks typically start at $10,000 and can exceed $1 million for significant contamination. Additional costs include regulatory fines (up to $25,000 per day of violation), third-party damage claims, business interruption losses, property value reduction, and increased insurance premiums. The total financial impact often exceeds ten times the cost of proper maintenance and testing programs. Many of these costs may not be covered by insurance, particularly if regular testing and maintenance haven't been performed. Regular professional testing and maintenance represent a small fraction of potential remediation costs.
