Glossary of terms for session 17

Battery of hydrams - (or parallel hydrams) a hydram installation where two or more hydrams are connected to the same source with different drive pipes, but usually with the same delivery pipe. This type of installation is used where the size of the hydram is limited.

Holding tank - (storage tank) the means of storing water once it has been pumped to the desired head.

Ram box - the small structure usually made out of concrete and/or wood which houses a hydram, protecting it from freezing, weathering, and possibly from vandalizing.

Series hydram - a hydram installation where two or more hydrams are used in series to pump water higher than one hydram could alone.

Spring box overflow pipe - a pipe placed in the wall of a spring box near the top for unused water to exit through.

Waste water drain - the drain in the bottom of a ram box which allows the waste water from the hydram to drain out.

Waste water series hydrams - a hydram installation where one hydram uses the waste water from another as a source to pump a higher percentage of the water.
