Architectural plumbing layout

[no _one]

hello po, this is architectural related, since nalalapit na po yung finals namin, pinapagawan po kami ng plumbing layout, since it is by group work po and yung napunta pong work na gagawin ko is Sewer Line Layout, saan po ba ako pwede makahanap ng resources na may sewer line layout, gagamitin ko lang po as guide. thank you po. nag try na rin po ako sa google but unfortunately wala po akong nakikita, thank you po
