Levels of water systems in the Philippines [11] Level I Stand-alone water points (e.g. handpumps, shallow wells, rainwater collectors) serving an average of 15 households within a 250-meter distance Level II Piped water with a communal water point (e.g. borewell, spring system) serving an average of 4–6 households within a 25-meter distance
A flush toilet (also known as a flushing toilet, water closet (WC); see also toilet names) is a toilet that disposes of human waste (i.e., urine and feces) by collecting it in a bowl and then using the force of water to channel it ("flush" it) through a drainpipe to another location for treatment, either nearby or at a communal facility.
A fixture unit is equal to 1 cubic foot (0.028 m 3) of water drained in a 1 + 1 ⁄ 4 inches (32 mm) diameter pipe over one minute. [2] One cubic foot of water is roughly 7.48 US gallons (28.3 L; 6.23 imp gal). A Fixture Unit is used in plumbing design for both water supply and waste water. Different fixtures have different flow requirements.

Lavatories and water closets normally connect to the water supply by means of a supply, which is a tube, usually of nominal 3/8 in (United States) or 10 or 12 mm diameter (Europe and Middle East), which connects the water supply to the fixture, sometimes through a flexible hose.
A reducer reduces the pipe size from a larger to a smaller bore (inner diameter). Alternatively, reducer may refer to any fitting which causes a change in pipe diameter. [15] This change may be intended to meet hydraulic flow requirements of the system or adapt to existing piping of a different size. The reduction length is usually equal to the ...
