An important goal of the assessment was to determine the number of residential septic tanks that are accessible by desludging trucks. San Fernando City has many rural and coastal areas that are not easily accessible by car or truck. In addition, it was noted in the survey that some houses are located far off the road, sometimes in excess of the length of a standard desludging truck hose.
=== Septic Tanks and Cleanouts ===

In the Philippines, septic tanks are often located under the kitchen or comfort room to allow for easy drainage. Unfortunately, in some instances, septic tank cleanouts have been covered by flooring or may have never existed. In still other cases, septic tanks are believed to be present, but the location of the septic tank is not known.
