Question

In a elementary school with 657 occupants, how many of each plumbing fixtures are needed?

Answer 1

As per 2015 Building Code, the minimum plumbing fixture required in educational facilities-

In case of Elementary School-

Water Closets(Urinals see section 412.9 of the International Plumbing Code) - 1 per 50

Lavatories - 1 per 50

Bathtubs / Showers - None

Drinking Fountains (See section 410 of the International Plumbing Code) - 1 per 100

Other- 1 service link

To determine the occupant load of each sex , the total occupant load shall be divided into half. To determine the required number of fixtures the fixture ratio or the ratios for each fixture shall be applied to the occupant load of each sex. Fractional numbers resulting from applying the fixture ratio shall be rounded up to the next whole number.

Each plumbing fixtures are needed as follows:

Total Occupants load = 657

half of the occupants load = 657/2 = 328.5

Water Closets = 328.5/50 = 6.57 = 7

Lavatories= 328.5/50 = 6.57 = 7

Bathtubs / Showers = None (In case of elementary school)

Drinking Fountains = 328.5/100 = 3.28 = 4

Other = 1 Service link.
