How to Build a Masonry Arch Over the Dug Well
Alvin Starkman M.A., LL.B., Casa Machaya, Oaxaca Bed and Breakfast.
This article describes the process of digging a well to provide usable water and the steps taken to make the well safe and sanitary. We include both technical advice and a description of the practical problems that one must encounter and overcome in providing usable water in an area where public water supply is absent or limited.

The article author, Alan Starkman is a retired Toronto attorney who operates the Casa Machaya bed and breakfast in Oaxaca Mexico. Mr. Starkman has written more than 90 articles about life and cultural traditions in Oaxaca, Mexico, and writes here about well digging from a lay person's perspective.
Take a look at the sagging, temporary lift used by the workers to remove stone and soil as the well was being dug (below left) and you will appreciate why expert well builders like to finish the job with a more functional arch over the Dug well opening
. Our masons built a temporary support scaffold over the well opening, then constructed a plywood arch against which a brick arch would be constructed.
Our photos below show the brick arch being completed over the Dug well. Once bricklayer has completed the arch (a couple of days), then he will wait a week or so take off his mold for the arc.
Next we will clean it as best we can, and then proceed. The masonry arc, being secure, will permit me to lower myself into the Dug (really "chiseled") well for an inspection. It will be the first time for me descending 12 meters into the ground
Watch out: never enter a confined space such as a dug well without proper safety precautions, including:
- Do not enter a dug well without first being sure that its construction and well sides are safe, sound, and protected from sudden collapse.
- Do not work alone. Have at least one able-bodied person standing by the entire time.
- Have spare emergency parts, lines, block and tackle at hand should the primary means of raising or lowering the inspector into the well fail.

Dug Well Safety: Providing a Ground-Level Wall & Well Cover
The brick wall we show constructed around our dug well (photo below left) serves two purposes.
- Prevent surface run-off from entering the well, improving its sanitation.
This function is particularly important in this example because the well is located on a steep hillside that transports a high volume of runoff during the rainy season.
See details at DUG WELL SANITATION PROTECTION - Prevent a child or animal from falling into the well. This safety function would be incomplete without also installing a secure cover on the well (photo, below right).

Your Canadian hosts spent four years building their home using a Oaxacan architect so you’re assured of classic Mexican flare, color and design, yet with all the conveniences of home without any cultural surprises. Our traditional adobe-stone-brick construction, and our breezy location just above the city’s downtown area ensure moderate temperatures year-round. Awake to the sounds of rooster calls and typical music echoing across the valley, yet you’re only minutes from the zócalo, the heart of downtown Oaxaca with its art galleries, museums, colonial churches and restaurants. Our accommodations combine the service and comfort of a modern Oaxaca hotel, with the personal touch of a quaint country inn. - Carlos Soberman, San Miguel de Allendex, Mexico kindly contributed the photograph of flooding during the rainy season in Mexico.
