The Truth About Property Infrastructure in Bali, Lombok and Sumbawa: 3 Issues That Can Make or Break Your Investment

Introduction: Infrastructure Determines Value

Bali, Lombok, and Sumbawa continue to attract foreign investors and dreamers looking to own a slice of paradise. From beachfront villas to remote eco-resorts, these islands offer stunning landscapes, warm hospitality, and a booming property market. But beneath the tropical appeal lies a hard truth: the value of your investment depends not just on location or design—but on something far less glamorous—infrastructure.

Many first-time foreign buyers underestimate the importance of water supply, reliable electricity, and stable internet connectivity. These essentials are often taken for granted in urban centers around the world, but in Indonesia’s island regions, they can make or break a property’s livability, development timeline, and long-term value.

This article offers a reality check. If you're planning to build or buy property, you need to understand the real challenges of property infrastructure in Bali, Lombok and Sumbawa. From digging deep wells to dealing with power outages and slow broadband speeds, we’ll explore what every smart investor should know before signing on the dotted line. Whether you’re a digital nomad, eco-developer, or luxury villa enthusiast—this is the groundwork you can’t afford to skip.

Water Supply: Not Always on Tap

When planning a dream villa or retreat, water may seem like the last thing you need to worry about. But in reality, a consistent and clean water supply is one of the biggest infrastructure challenges property owners face in Indonesia’s islands—especially in Bali, Lombok, and Sumbawa.

In Bali, municipal water is supplied by PDAM, but coverage is limited and increasingly strained due to population growth and tourism. In popular regions like Uluwatu, Canggu, or parts of Ubud, many properties rely on private wells, which can be shallow, contaminated, or prone to drying out during the dry season. Some villas even suffer from low water pressure or intermittent supply—especially during peak tourist periods.

In Lombok and Sumbawa, the situation is even more complex. These islands have less developed infrastructure, particularly in rural or emerging investment zones. Here, rainwater harvesting, deep-well drilling, or trucking water in during dry spells are often the only options. For investors looking to build sustainable or off-grid projects, this poses both a challenge and an opportunity—but one that comes with real costs.

Drilling a proper deep well can cost anywhere between IDR 50 million to IDR 200 million, depending on depth and soil conditions. Add to that filtration systems, water tanks, and routine maintenance, and water becomes a significant line item in your property budget. Worse, without careful planning, over-extraction in coastal zones can lead to saltwater intrusion—a common issue that has affected parts of southern Bali and Lombok.

From a sustainability standpoint, water access is now one of the most debated aspects of property infrastructure in Bali, Lombok and Sumbawa. Environmental groups are calling for stricter controls and better planning as aquifers dry out and demand increases. Foreign buyers often assume water is a given, but local builders and consultants know that it’s a key point of due diligence.

Tip: Always conduct a hydrogeological survey before buying land. Knowing the water table depth and quality can prevent costly surprises later.

If you're investing for the long haul, understanding the realities of water is essential. It’s not just about convenience—it’s about the very viability of your development and the long-term sustainability of property infrastructure in Bali, Lombok and Sumbawa.

Electricity: More Than Just a Connection

Powering your dream property in paradise isn’t as simple as flipping a switch. In Indonesia, PLN (Perusahaan Listrik Negara) is the sole state-owned electricity provider, and navigating their systems can be a challenge—especially for foreign investors. Whether you're building a private villa, boutique resort, or coworking space, understanding the electric grid is crucial to success in property infrastructure in Bali, Lombok and Sumbawa.

In Bali, electricity supply is relatively stable in major urban areas like Denpasar, Kuta, and Sanur. However, power outages still occur—especially in areas with rapid development, like Canggu or Uluwatu, where demand often outpaces infrastructure upgrades. These blackouts are usually short, but they can still disrupt daily operations, especially for digital nomads or hospitality businesses.

In Lombok and Sumbawa, the challenges are more acute. Remote or rural areas often experience frequent and longer outages due to weaker grid capacity and slower emergency response. New developments may wait weeks—or even months—for proper PLN connections, especially in growing investment zones like Sekotong or Hu’u. In some cases, projects are delayed simply because electricity hasn’t reached the area yet.

For new properties, applying for a PLN connection involves submitting documents, securing land legality, installing meters, and sometimes paying infrastructure development fees. Costs vary based on load requirements, distance from existing lines, and transformer needs. This process can stretch timelines, and navigating the bureaucracy without local help can be frustrating for foreign buyers.

As a result, many investors now consider off-grid solutions. Solar panels are increasingly popular in Bali, thanks to abundant sunshine and growing awareness around energy sustainability. Backup generators are also common—especially for businesses reliant on refrigeration, Wi-Fi, or air conditioning. While the upfront cost is higher, these options reduce dependence on an unpredictable grid and improve the overall resilience of property infrastructure in Bali, Lombok and Sumbawa.

Energy efficiency is another growing trend. Smart appliances, LED lighting, and solar water heaters can reduce load, save money, and limit environmental impact—especially important in places where electricity is expensive or unreliable.

Ultimately, electricity isn’t just a utility—it’s a core pillar of livable, profitable, and future-ready property infrastructure in Bali, Lombok and Sumbawa. Failing to plan for it can lead to operational headaches and added costs down the road.

Internet & Connectivity: Paradise ≠ High Speed

In the age of remote work, a strong internet connection can make or break a property investment—especially for villas, resorts, or coworking spaces. Unfortunately, when it comes to property infrastructure in Bali, Lombok and Sumbawa, internet connectivity isn’t always as beautiful as the view.

In Bali, connectivity is generally reliable in digital nomad hotspots like Canggu, Sanur, and Ubud. Fiber-optic services from providers like Biznet, Indihome, and MyRepublic are widely available in central areas. But just a few kilometers out—toward Tabanan, Bukit, or north Bali—connection speeds and reliability can drop significantly. Outages do happen, and bandwidth can be inconsistent during peak hours.

Lombok paints a more mixed picture. Mataram and Senggigi have acceptable fiber coverage, but rural areas like Kuta Lombok or Sekotong may only have limited access to fixed-line internet. Signal strength for mobile networks (Telkomsel, XL, Indosat) varies depending on proximity to a cell tower. Some businesses in the south rely on 4G mobile tethering or Wi-Fi routers but experience fluctuating speeds, especially during storms or network congestion.

In Sumbawa, fiber-optic infrastructure is scarce. Mobile internet is the primary option, with occasional access to VSAT or satellite internet in tourism-heavy areas like Lakey Peak. While 4G and even 5G have reached select towns, consistent high-speed service remains a major challenge in remote or undeveloped regions. For foreign investors, this is a critical consideration when evaluating property infrastructure in Bali, Lombok and Sumbawa.

Digital nomads, content creators, and tech-enabled businesses all need reliable, fast Wi-Fi, but it's not guaranteed—especially if you’re building outside the main urban hubs. Many expat property owners opt for dual-provider setups, using two different ISPs to ensure backup connectivity. Others install signal boosters to improve coverage or invest in satellite internet systems for guaranteed access.

The extra cost of these solutions—from installation to monthly fees—must be factored into your budget when assessing property infrastructure in Bali, Lombok and Sumbawa. It’s not just about speed, but about stability, uptime, and adaptability in case of outages.

If you're envisioning a seamless smart home, remote office, or luxury retreat with global streaming and booking systems, internet limitations could become one of the biggest pain points in your project. Proper planning now can prevent expensive upgrades later—and keep your future guests (or Zoom calls) from getting dropped.

Due Diligence Before You Build

When investing in land or property abroad, the first instinct is often to focus on aesthetics—beaches, views, and trending locations. But smart investors know that property infrastructure in Bali, Lombok and Sumbawa can be the difference between a dream investment and an expensive nightmare. Infrastructure isn’t just a “technical” consideration; it has major implications for legal permits, daily livability, and future resale value.

Before you build, due diligence on infrastructure must be a top priority. This includes a mix of technical assessments, legal compliance checks, and local knowledge that only experienced professionals can offer.

Start with zoning verification. Many foreigners have purchased plots only to find they’re located in “green belt” areas—land zoned for agriculture or conservation, not residential or commercial construction. Building in these areas without the proper permits can lead to fines, demolition orders, or project halts. A proper zoning review through the Land Office (BPN) or with a local notary is critical.

Next, confirm electricity access with PLN, the national electricity company. Just because a neighboring property has power doesn’t mean your plot will. You’ll need to apply for a new connection, which can take months depending on the area's capacity and infrastructure. It’s important to factor in the timeline and cost of grid connection or consider alternative solutions like solar power during planning.

Water supply is another challenge. Conduct a hydro survey to determine whether groundwater access via a well is feasible, or whether rainwater harvesting systems need to be installed. The cost of drilling, filtering, and maintaining wells can add significantly to your project budget—especially in coastal or arid areas.

Finally, check for internet feasibility. Contact service providers in advance to confirm whether fiber-optic lines or mobile internet coverage exists in your target area. For digital nomads or short-term rental owners, poor connectivity can be a dealbreaker.

Working with local consultants, legal advisors, and infrastructure agencies is not optional—it’s essential. They understand the complexities of property infrastructure in Bali, Lombok and Sumbawa, from evolving regulations to unspoken local processes. Their guidance can help you avoid pitfalls, streamline approvals, and ensure that your investment is functional, legal, and future-proof.

Before you break ground, make sure the ground is ready. Infrastructure readiness is the true foundation of your property.

Conclusion: Build Smart, Not Just Beautiful

Tropical landscapes, breathtaking views, and vibrant culture make Bali, Lombok, and Sumbawa irresistible for foreign property investors. But behind every stunning villa or boutique resort lies a crucial, often invisible foundation: property infrastructure in Bali, Lombok and Sumbawa. Without reliable access to water, electricity, and internet, even the most well-designed property can become unlivable—or unprofitable.

Too often, foreign buyers focus solely on aesthetics and location, underestimating the costs, delays, and stress that come from poor infrastructure. A gorgeous beachfront lot may seem like a bargain until you discover that the area has no clean water source or suffers from constant blackouts. In some regions, simply securing stable internet could require satellite equipment and extra licensing.

The good news? These risks are manageable—with the right preparation. By conducting proper due diligence, consulting local professionals, and budgeting for infrastructure investments, you can avoid common pitfalls. Whether you're planning to live, rent, or resell, your investment’s success hinges on more than just style—it depends on stability, functionality, and future-proofing.

Property infrastructure in Bali, Lombok and Sumbawa is improving, but it still varies greatly by location. Choose your plot carefully, ask the right questions, and don’t rush the process. Because building smart—not just beautiful—is the only way to create real, lasting value in paradise.
