Manhole repair
Sauereisen Manhole ChimneySeal No. F-88 is a chemical-resistant, elastomeric lining composed of a fiber-reinforced, asphalt-modified urethane. The lining prevents the inflow and infiltration of groundwater into the chimney section of manholes. It also accommodates horizontal and vertical movement of the substrate due to freeze/thaw cycles. It can significantly reduce the cost of treating additional sewage volume that originates as inflow through voids and cracks along manhole grade rings and chimneys.

Tank coating
Sherwin-Williams offers its Duraplate® UHS Ultra High Solids Epoxy with fluorescing Optically Active Pigments (OAP), allowing tank lining applicators to check the coating instantly for pinholes, holidays and other discontinuities and verify uniform coverage and proper film thickness. The new formulation is the only product of its type meeting the requirements of NSF Standard 61 for potable water tanks of at least 1,000 gallons. The coating uses Duraplate UHS Epoxy as the vehicle to hold the pigment, and is available as a single- or multi-coat application. A ‘civilian’ application developed from a technology supplied to the U.S. Navy, the fluorescing technology has doubled the service life of marine ballast storage tank coatings simply by illuminating insufficient film thickness wherever it occurs.

Level control valves
OCV Control Valves manufactures a variety of level control valves for use in water storage tanks and reservoirs. Depending on the application, the company can provide the Model 3333 Two-Way Altitude valve, which senses tank head pressure to control water levels, or the Series 8000 On/Off Float valve that monitors levels through a rotary disc float control that implements an on/off type action. The Model 3333 and Series 8000 are designed to operate automatically from line pressure and maintain a desired level in a tank or reservoir by opening and filling the tank when fluid is below the high level point and closing tightly when the desired level is reached.
