Buying Guide
Getting Water, Power & Internet to Your Lot
Getting water, power, and internet to your lot is the most practical question in any land purchase on the Oaxaca coast — and the one first-time buyers ask last. The answer is knowable before you sign anything: every lot has a different connection story, and the differences are visible if you look. Here is how each utility actually gets connected, what it honestly costs, and how long it takes.
Most buyers start with the paperwork: the title, the boundaries, the notario. Correct, but only half the story. The other half is the practical business of getting water and power to land in Mexico — and, these days, internet — because a lot with perfect papers and no workable water is still just a place to camp. The utilities are the quiet difference between a lot you can build on and a lot you can only look at. Here is how each one gets connected: the process, the honest costs, and the timelines.
Key facts
- Connectability is about distance. Whether a lot can get water, power, or fiber depends on how far it sits from existing lines — and that distance is checkable before you buy.
- CFE is the only power provider. The Comisión Federal de Electricidad runs the national grid, and the connection process is standard everywhere — but the cost is not.
- Water often means a well or delivery. On raw lots, a toma de agua (piped connection) is the exception; a pozo (well) or a pipa (delivery truck) is the norm.
- Septic is the norm. There is little sewer on the coast, so a fosa séptica (septic tank) and leach field are part of nearly every build.
- Internet is uneven. Fiber and fast cellular exist in town centers; remote hillsides still rely on Starlink and patience.
Ask first
The Three Questions Every Lot Asks
Every lot on this coast answers three questions, in order. Is it serviced — is the infrastructure already there, with a meter and a connection in place? Is it connectable — can new service physically reach the lot, and how far does it have to travel? And at what cost — the connection, once distance, voltage, and paperwork count? A serviced lot is the easiest purchase on the coast; a connectable one is normal, with known work and known money attached. A lot that cannot be connected at a reasonable price is a different purchase entirely — fine if you want off-grid, expensive if you do not.
These questions belong in the same due-diligence pass as the legal work: the complete guide to buying land in Oaxaca walks through the title, the promesa de compraventa, and the notario. This article is the companion piece — the services that make a lot livable. Ask both sets of questions before you sign anything.
Price is what you pay for the lot. Cost is what you pay to live on it.
The water
Water: Toma, Pozo, or Pipa
There are three ways a lot gets water on the Oaxaca coast, and the right answer depends on the street, not the brochure.
A toma de agua is the piped municipal connection. It exists in parts of Puerto Escondido and Santa María Huatulco and in some town centers, run by the municipality or a local comité de agua potable (drinking-water committee). To get one, you apply at the local office with your property documents, pay a connection fee, and a meter goes in. When a line is at the lot, the process takes weeks and the fee is modest. Caveats: coverage is patchy — a line can end two blocks from the lot — and pressure is seasonal, so even connected homes keep a tinaco (roof tank), and most add a cisterna (underground storage).
A pozo, or well, is the common answer on raw and hillside lots. Drilling means a rig, a pump, and a permit from CONAGUA, the federal water authority. Depth varies — some lots hit water at thirty meters, others go much deeper — and coastal wells are often brackish: fine for showers and gardens, not for drinking. Test the water before you buy, not after.
A pipa is the tanker truck that delivers water — how most of the coast actually gets wet. You need a cisterna to store the load and a pump to move it into the house, plus a road a heavy truck can manage in both seasons. A load runs from a few hundred to over a thousand pesos depending on distance and season.
For the day-to-day reality of living with these systems — storage math, seasonal pressure, monthly costs — the utilities reality check covers life on the other side of the connection. This is the how-to-connect version.
The power
Power: Your CFE Connection
Electricity comes from one place: CFE, the Comisión Federal de Electricidad, Mexico's national power company. There is no competing grid, and the process is standard — the same application in Puerto Escondido, Mazunte, or Huatulco.
You apply for a new service at the local CFE office or online, with ID and proof of the property — the escritura if you own, the promesa de compraventa if you are buying. For a basic domestic connection, that is often the whole paperwork. For a larger load — air conditioning across a big house, a workshop, a hard-working pump — CFE will want an electrical project signed by a certified electrician, plus the panel and grounding done to code.
Then CFE studies the site, and this is where the honest ranges come in: connection fees vary widely by distance to the nearest pole and by voltage. A lot with a line at the boundary may connect for a few hundred dollars plus deposit, in weeks. A lot a kilometer from the nearest line needs an extension, which CFE quotes after the study — and the quote can run into the thousands, depending on poles, wire, and transformers. A nearby lot may cost a fraction of a distant one; that single fact explains a lot of coastal price differences.
Timeline honesty: weeks when the line is close, months when it is not. After connection, the meter (medidor) runs on subsidized residential rates, with a summer rate in the hot months. The utilities reality check covers outages, storm season, and monthly bills; the point here is the connection itself.
The signal
Internet: Fiber, Cellular, or Starlink
Internet is the utility that did not exist when most of this coast was settled, and it is the one buyers ask about most. The honest map is simple: excellent in town centers, thin on remote hillsides.
Fiber reaches into the town cores — parts of Puerto Escondido, La Crucecita in Huatulco, and increasingly San Pedro Pochutla — served by Telmex and, in places, Totalplay or Izzi. Where fiber passes the lot, installation is fast: days to a couple of weeks. Where it stops a few blocks away, the fiber company will tell you plainly.
Cellular data is the reliable middle ground. Telcel has the best coastal coverage, with 4G in the towns and along the main highway and 5G appearing in spots. A phone plan with a hotspot, or a data-only SIM in a router, handles remote work for most people — until a storm or a busy weekend slows it down.
Starlink is the honest answer for remote lots. It works anywhere with a clear view of the sky, which on a jungle hillside means cutting back the canopy — trees are its real enemy. Hardware costs a few hundred dollars, the monthly plan is a fixed fee, and it needs electricity, which on a raw lot means a generator or solar. Latency is fine for video calls. For a deeper look, the remote-work guide has the full breakdown.
The waste
Septic and Wastewater: What Goes in the Ground
Sewer lines are rare on this coast. Most municipalities run them only in their densest cores, so most lots — including most new builds — use a fosa séptica: a septic tank buried on the lot, paired with a leach field (pozo de absorción) where filtered water soaks into the ground. It is standard, legal, and unglamorous, and it works when designed for the house.
The practical rules are simple. Size the tank for the number of bedrooms, not the guests you hope to host. Keep the leach field away from the well, the property line, and anything downhill you drink from. Leave access for the pump truck — a fosa needs emptying every few years. If the lot sits on rock or heavy clay, drainage gets harder and pricier — ask a local builder before you buy, not after. Huatulco's planned bays are the organized exception, with real sewer and hookup fees. And nothing goes into the arroyo — the creeks that run to the beach are the coast's lifeblood, and pumping waste into them is illegal and poisonous.
The numbers
Utilities at a Glance
Honest planning ranges, not quotes. Prices move with the peso, the season, and the distance from town; get written numbers from local suppliers and the CFE office before you commit to a lot that depends on them.
| Utility | Typical status on the coast | Cost range (with caveats) | Timeline |
|---|---|---|---|
| Water — piped (toma de agua) | Town cores only; coverage is patchy street by street | Modest connection fee plus meter; the cheap case is a line already at the lot | Weeks when the line is at the lot |
| Water — delivery (pipa) | The norm for most homes and raw lots | A few hundred to over a thousand pesos per load; add a cisterna and pump | On demand — but only if the truck can reach you year-round |
| Water — well (pozo) | Common on hillside and remote lots | Drilling runs into the thousands and varies with depth; CONAGUA permit required | Weeks to months, plus water testing |
| Power (CFE) | Grid reaches most town lots; rural lots vary widely | From a few hundred dollars plus deposit near a line, to thousands for a distant extension | Weeks near a line; months for extensions |
| Internet — fiber | Town centers only | Standard installation fees; cheapest where fiber already passes | Days to a couple of weeks |
| Internet — cellular | Towns and the highway corridor | A data plan, or a router if you want it dedicated | Same day |
| Internet — Starlink | Anywhere with a clear view of the sky | One-time hardware cost in the hundreds of dollars, plus a monthly fee; needs power | A week or two for the kit |
| Wastewater — fosa séptica | The standard for nearly every build | Low thousands of dollars installed, depending on size and soil | Days of work, once you build |
The homework
How to Verify Before You Buy
None of this needs to be a leap of faith. Before you make an offer, run this list.
Ask the seller for receipts. Past CFE bills prove the meter is real and show the monthly pattern; water receipts do the same for a toma; a well permit shows the pozo is legal. A seller who has them hands them over. A seller who does not gets asked why.
Talk to the neighbors. They know the pressure in May, the outage frequency, which pipa trucks come down the road, and what the comité charges. Neighbors are the best due-diligence tool on the coast, and they are free.
Visit the CFE office. Take the lot's location and ask how far the nearest line is and what a new service would take. You may not get a written quote on the first visit, but you will get a straight answer about distance and feasibility.
Check the survey (deslinde) for easements. The plano shows rights of way for power lines and water mains, whether a neighbor's line crosses your lot, and whether there is room for a leach field. It also shows access — a utility in itself when you need a pipa truck.
The fine print
Hidden Costs to Budget For
The connection fees are the visible part. The hidden part is everything between the lot line and the house, and it is where budgets quietly die.
Trenching. Power and water both need a trench from the street to the house — through sand, rock, or clay — and per-meter costs add up fast. Get it quoted by a local excavator, not assumed.
Permits and studies. CFE's site study, the water connection paperwork, a CONAGUA filing for a well, municipal fees for the build itself — none of it is huge, but all of it exists. The building permits guide maps the municipal and federal layers.
Transformers and panels. If the nearest line is low-voltage and your house wants more, a transformer may be required — the biggest single line item in rural electrification. The panel, grounding, and meter housing are yours to provide.
Water storage and pumps. A cisterna, a tinaco, a pressure pump, and the plumbing between them: low thousands of dollars installed, and mandatory even with a toma, because the coast's dry season does not negotiate.
The rule of thumb is not a number, it is an attitude: budget more than the first quote, and treat the utilities as part of the lot's price, not an afterthought. Lots that are honest about their utility work are worth more than lots that hide it — and the coast is full of both.
