Spanish to English Other Government / Politics Ecuadorian water bill (Qu

Good evening. I'm working on a Quito Water and Sanitation Department water bill receipt. Under the "Detalle de Valores a Pagar" section, in the "Facturación Del Mes (A) table, the acronym "P.U." is listed.

Here's the context, within the aforementioned table:
CP CA DESCRIPCIÓN P.U. DESC. TOTAL
XX 1 Agua Potable (decimal number)
XX 1 Alcantarillado (decimal number)
XX 1 Administración. (decimal number)

As always, a thousand thanks!
