Download the form
DA Form 4178 handles one job: facilities engineering operating log (sewage-supplementary). The official title is FACILITIES ENGINEERING OPERATING LOG (SEWAGE-SUPPLEMENTARY). Download it below, fill it in, sign it, send it where your directive says. The edition on this page is 10/01/1973, status ACTIVE, running unknown page(s) with about unknown fields to complete.
Authority sits in two places. G-9 owns the form, AR 420-1 says when it is raised and where it goes. Routine cases need neither read in full — the page itself carries the sequence. The entries are completed by their subject or by unit administrative staff working from what that person supplies.
none published here are available and the decision takes one second. Type your entries: fillable pdf. Write them: printable pdf. The published layout is common to both, so the format governs your method and nothing more.
A standalone reader is the safe choice for fillable work. Browser viewers vary in whether entered data survives the session, and there is no warning when it does not; a one-field save test settles it in seconds.
Free, unregistered, unmodified. What arrives is what the publisher released.
The heading entries carry more weight than the body. Name spelled as in official records, identification number, organisation, date prepared. Retrieval runs on those values, so a transposed digit or a casual spelling costs someone a file search. Fill them before anything else.
Move between fields with tab; the build-time order follows the page and misses nothing. Click check boxes and option buttons, and expect an exclusive group to release the old choice when you set a new one. The trap is field width. Single-line fields do not wrap, so an overlong entry displays complete on screen and prints cut at the margin — put it in remarks or on a continuation instead. Mark inapplicable fields rather than leaving them blank, since an empty box carries no information about whether the question was read.
The signature closes the form and nothing precedes it. Draft status holds until it is applied, by hand or by an accepted electronic method. Countersignatures go in printed order, each dated at signing. Then one final read from the top, looking for the four recurring defects: empty mandatory fields, swapped digits in identification numbers, day-month inversion in dates, and residue from a reused file that goes forward as though intended.
The Privacy Act statement is read before the personal entries, not after. It gives the collection authority, the purpose, the routine uses and whether disclosure is mandatory or voluntary. Once filled, your copy is a personal record and gets stored and transmitted accordingly.
The prescribing directive names the destination; office custom does not. Depending on the case that means a specific office, the unit administrative channel, or the personal record. Keep a copy first, because the original does not come back. Retention runs on the applicable records schedule.
Related forms are found by series and number. DA series documents under the same proponent or the same prescribing directive are commonly required as a set, and any form named on the face of this one goes forward with it. Assemble continuations, covers and transmittals before submitting, not after the query comes back.
A stored file goes stale silently. The proponent revises, a new edition date is published, and your copy says nothing about it — so compare the printed date against the edition in force before typing into it again. Completed submissions on an earlier edition are not reopened.
The files are copies of published Department of the Army forms. This site has no official connection, no authority to issue anything, and no basis for saying whether an office will accept a given submission. None of the text is legal advice. Real questions — entry, requirement, eligibility — belong with G-9 or the administrative office servicing your unit.
