The bank was established by Alfonso Yuchengco on September 23, 1960, as Rizal Development Bank, a small development bank in Rizal province. [13] It was later upgraded to a commercial bank upon the approval of the Bangko Sentral ng Pilipinas and, in 1963, began operation as such under its present name Rizal Commercial Banking Corporation (RCBC).

A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.
Storm drain grate on a street in Warsaw, Poland Storm drain with its pipe visible beneath it due to construction work. A storm drain, storm sewer (United Kingdom, U.S. and Canada), highway drain, [1] surface water drain/sewer (United Kingdom), or stormwater drain (Australia and New Zealand) is infrastructure designed to drain excess rain and ground water from impervious surfaces such as paved ...
the design drain spacing (L) can be found from the equation in dependence of the drain depth (Dd) and drain radius (r). Drainage criteria One would not want the water table to be too shallow to avoid crop yield depression nor too deep to avoid drought conditions. This is a subject of drainage research.
The interception rate of channel drainage is greater than point drainage and the excavation required is usually much less deep. The surface opening of channel drainage usually comes in the form of gratings (polymer, plastic, steel or iron) or a single slot (slot drain) that run along the ground surface (typically manufactured from steel or iron).
When a structure is so severely corroded that human entry is a risk, spinning head application permits an “un-manned” consolidation of the manhole. High pressure dry spray: this method, also called “shotcrete” or “gunite” is allowing a faster rate of rehabilitation, and also to make a thicker application in a single pass. The main ...
A percolation test consists of digging one or more holes in the soil of the proposed leach field to a specified depth, presoaking the holes by maintaining a high water level in the holes, then running the test by filling the holes to a specific level and timing the drop of the water level as the water percolates into the surrounding soil.
