< on 8/7/2003 9:26 PM >
|  | | | NCUE went on a draining trip recently and now I am in the process of writing it up, but I need a primer in the vocabulary of draining. Anyone got a good primer on drainspeak?

Universal terminology
RCP: Round Concrete Pipe
CMP: Corrugated Metal Pipe
CSO: Combined Sewer Overflow; a pipe designed to channel excess sanitary sewer flow into storm sewers or above-ground creeks during heavy storms, in order to prevent the sanitary sewers from backing up into peoples' homes and yards. Necessary in areas where there are still combined sewers carrying both stormwater and sanitary wastewater, or where many homes' eavestroughs remain connecting to the sanitary system.
Creekwater: Water from a natural stream or creek.
Stormwater: Urban runoff from roads and buildings.
Sanitary Sewer: Pipes carrying wastewater from houses, businesses, etc to a treatment facility (one hopes) or a large body of water (still too often).
1800: In Canada, drains are measured in millimeters, and a section of drain pipe will often be referred to by its measure, especially by Albertan drainers. 1800 mm is approximately 6 feet.
Catchbasin, Gutterbox: Small structure into which stormwater flows from road or ditch before entering the drain itself. The catchbasin is deeper than the small pipe that drains it, preventing heavy debris from entering the storm sewer or creek drain.
Churn Blocks: Blocks of concrete, usually square but sometimes more exotically shaped (I've seen cylinders), designed to maintain a constant rate of flow by preventing eddies, cross-currents and other shortcircuiting. You'll find these things most often where water goes down a slide, either inside the drain or at the infall/outfall.
50-year, 100-year, or Regional Storm Event: Model used in designing stormwater management systems, from a regional-scale down to the storm sewer on the road outside your house.
Gross Pollutant Trap: Usually a curving, vertical structure, containing powered mechanisms designed to remove large items from the flow. If you run into one of these things, you're in the wrong place. I've occasionally used this name to refer to settling pools, but it's probably incorrect.
Fall Pool: Where a lot of water is made to fall a substantial distance, engineers insert a fall pool to absorb the energy of the falling water, preventing damage to the drain. These things can be a real pain.
Infall: Where a drain begins from a surface water source such as a creek.
Outfall: Where a drain falls out into a body of water.
Junction: Where two or more pipes converge, often within a different structure than the surrounding pipes.
Manhole room: A structure, usually larger than the surrounding drain, containing an access shaft and a manhole.
Oviform: An egg- or oval-shaped pipe.
Settling Pool or Tank: A deep pool used to reduce flow and remove sediment and heavy contaminants and solids from the water.
Step Irons, Wall Irons: Curving rungs stuck into the drain wall that serve as a ladder. They are used instead of regular ladders because they present far less surface area to a torrent of water, and are thus less likely to be damaged by said torrent.
Trunk: A large pipe carrying the flow of many smaller tributary pipes.
Watertable: The average depth of the water in the drain.
Weir: A wall or obstruction used to control flow, usually as part of a settling pool.
My house terminology:
Barn Doors: Two-door gate over an infall/outfall, opening horizontally like barn doors, and often chained.
Beaches: Most often found in creek drains, but also can be found in storm drains improperly protected from construction zone erosion. Occur where heavy loads of soil, pebbles and rocks have entered the drain and been deposited there, slowly building up until they form beaches that sit above the water level during dry-weather flow.
Bevel Box, Chamfered Box, Fillet Box: A rectangular drain with chamfered or filleted corners.
Iron Mask: Heavy, barred grate dropped into place over an infall or outfall and designed to preventing large debris and unauthorized persons from entering the drain. Looks like a prison cell. An Iron Mask can only be lifted via a truck-mounted winch from the roadway above.
Sabre-toothed Guard, Thresher Guard: Curving, metal guard that wraps itself over an infall/outfall, again for the purpose of preventing unauthorized access and debris buildup inside the drain. The skin of the guard is composed of long, usually round lengths of metal running parallel from the top of the grate to the bottom, supported by struts below them. There's often enough room to squeeze in between the concrete exterior structure and the outside edge of the guard.

They're not a pain if the problem is dealt with using a spiral staircase instead of just a shaft and pool.

I've heard them referred to as step irons, but close enough. Old ones are metal, and often rusted nearly all the way through. The newer ones they use these days are formed out of rubbery black plastic.
Ninj's infilspeak dictionary has some draining terms in it too.

All I can say is that the Office Products Expo 1995 had sure as hell better be in the Twin Cities.

Yeah, that's my slang subconsciously seeping through. I fixed it a few minutes before you posted : )

If it is, I want you to take LOTS of your uber-sweet pictures in those kinds of places. I'd gladly show you around and do some real exploring too if you made it down here sometime.
