In 1919 WSSC Water purchased the Takoma Park water system, which drew water from Sligo Creek. To provide additional capacity, the commission bought a used water filtration plant from Culpeper, Virginia, and installed the system along the Northwest Branch near Burnt Mills. This facility was replaced with a new system, the Robert B. Morse Water ...
The Washington Suburban Sanitary Commission Police patrol more than 1,000 square miles of the WSSC's Sanitary District located in Montgomery and Prince George's County. Within that district they also serve more than 250 fixed facilitates and protect 6,000 acres of WSSC Watershed property located in Howard County.
Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).
WSSC may refer to: Washington Suburban Sanitary Commission , the water and sewer system operator for the Maryland suburbs of Washington, DC Western Slope Safety Council, a Colorado occupational safety, health, and environmental organization for the oil and gas industry
This schematic shows the component parts of a typical leak-down tester. The gauge on the right is held at a standard pressure by adjusting the pressure regulator while the gauge on the left shows an example reading of 85, or 15% leakage. A leak-down tester [2] is essentially a miniature flow meter similar in concept to an air flow bench. The ...
In 2001, water supplied by the Authority was found to contain lead levels of at least 1,250 parts per billion (ppb)—about 83 times higher than the accepted safe level of 15 ppb. [17] The discovery was made by Marc Edwards , a civil engineering professor specializing in plumbing who DC Water had hired to investigate complaints of plumbing ...
Leakage of this type can be measured by observing that the current flow at some point in the circuit does not match the flow at another. Leakage in a high-voltage system can be fatal to a human in contact with the leak, as when a person accidentally grounds a high-voltage power line. [3]
