HYDROSTATIC MONITORING -Some fuel storage systems only monitor the tank but the ,w <br /> most common leak points are within the tank sump(s), <br /> typically improperly installed piping penetrations or , <br /> corroded equipment. Single-wall tank sumps, turbine <br /> or spill (fill/vapor), utilize monitoring sensors to protect - is <br /> against liquid within the sump which can cause steel <br /> components to corrode. However the most devastating *" <br /> potential concern is environmental contamination. <br /> A double-wall hydrostatically monitored sump will <br /> protect against both internal and external leaks. Transport or handling damage is instantly identifiable by a contrasting <br /> colored brine solution, an exclusive feature of a CSI hydrostatically <br /> CSI double-wall sumps have two independent walls with monitored double-wall tank. <br /> an annular space filled with monitoring fluid.The design <br /> is ideal for communicating the fluid level in all directions <br /> equally. Hydroguard System sumps also feature EZ-Fit <br /> adhesive channels that reduce installation time and „ , ?I <br /> expense. EZ-Fit sumps are available in 42", 48", and 54" <br /> diameters. - . <br /> ' Hydroguard is the premier underground storage solution <br /> for the petroleum industry. <br /> OUTER WALL BREACH <br /> HIGH GROUNDWATER <br /> If the groundwater is below the tank top,the non-toxic If the groundwater is over the tank .. <br /> ,the reservoir will overfill <br /> monitor fluid drains into the ground causing the reservoir with groundwater and activate the high level alarm on the <br /> to drain. reservoir sensor. <br /> Reservoir Drains- Groundwater Level—--- <br /> i <br /> Groundwater Level, Reservoir Overfills...--- � <br /> Outer Tank Breach- <br /> OuterTank Breach---.,,_ <br /> INTRODUCTION 2 <br />
