some words I dont know, Im trying to understand a technical document written in spanish

Question

The document is in my field Civil Engineering - particular to Water and Energy. Words I cannot find in dictionary or other context:
TRAFO DESMULTIPLICADOR ACOMETIDA "CAMARA DE VALVULAS" POLIPASTOS DEPOSITOS (Would this be a Warehouse? Like a depository? Or is it a PLANT (like a water distribution plant, water refining plant)'

Answer 1

camara de valvulas = valve chamber desmultipicador= unmultipier (?) acometida= connection, attack polipastos= multi-grass (?) depositos= warehouses, stores trafo= ?

Answer 2

If the word was dispositivo rather than depositos, I would go with the water treatment plant.

The first items sounds like a step-down (or ac to dc, etc.) transformer connection and the other like a valve chamber with a hoist for removing the valves for replacement/repair.

Answer 3

¨The Google Spanish-English translator has it as

transformer reducers connection valve chamber hoists deposits
