Look, I’m not going to sugarcoat it—setting up utilities when you first move to Oʻahu can feel like trying to figure out a puzzle where half the pieces are missing. But here’s the good news: once you know the drill, it’s actually pretty straightforward. And unlike the mainland where you might be juggling five different companies, we’ve got it a bit simpler out here.
Let me walk you through exactly what you need to know about getting your electricity, water, and trash service up and running so you can focus on the important stuff—like finding the best plate lunch spot in your neighborhood.
Electricity: Hawaiian Electric (HECO)
First things first: power. Hawaiian Electric (or HECO, as everyone calls it) is your only option for electricity on Oʻahu. There’s no shopping around for providers here, which actually makes things easier.
Getting Started
You can set up service through HECO’s Online Customer Service Center. They need at least one business day’s notice, but honestly? Give yourself a few days of buffer if possible. If you’re in a bind and need same-day service, they can sometimes make it happen for an extra $25—but you’ll need to get approval first and hope they have availability.
What It’ll Cost You
There’s a $20 service establishment fee right off the bat. You might also need to put down a security deposit, though the amount varies depending on your situation. The good news is that if you’ve got a solid payment history with a utility company from the mainland, HECO might waive that deposit—just have a letter of credit ready from your previous provider.
Your actual electric bill? That’s the real sticker shock. Hawaii has some of the highest electricity costs in the nation, with rates typically ranging from $150-$200 monthly for an average household. Yeah, it’s expensive. We’re an island chain in the middle of the Pacific, and most of our power still comes from imported oil. It is what it is.
Pro Tips
The meter reconnection happens between 8 a.m. and 4 p.m. on your requested service date, so don’t plan your move-in for early morning or late afternoon if you want lights right away. And if anyone in your household relies on medical equipment or life support, make sure to tell HECO immediately—they’ll flag your account for priority service during outages.
Water: Board of Water Supply (BWS)
The Honolulu Board of Water Supply handles water for the whole island, and their water is actually some of the best you’ll ever taste—seriously, we’ve got incredible natural aquifers here.
Setting Up Service
You’ve got options: call them at (808) 748-5000, visit their office at 630 South Beretania Street (open weekdays from 7:45 a.m. to 4:30 p.m.), or use their online request forms. The online route is usually the smoothest—less hold time, and you can do it whenever works for you.
The Costs
Water bills on Oʻahu are pretty reasonable compared to electricity—usually around $30-$50 per month for a typical household. BWS bills every two months rather than monthly, which can catch people off guard the first time. And yes, you might need to put down a deposit, but like HECO, having good utility payment history from the mainland can help.
What You Need to Know
If you’re renting, make absolutely sure your landlord has transferred the water service into your name. There are stories of people who thought water was included in their rent, only to find out the previous tenant’s account was still active. Not a situation you want to deal with down the road.
Trash Collection: City & County of Honolulu
Here’s where it gets easy—the City & County of Honolulu Department of Environmental Services handles trash collection, and it’s included in your property taxes if you own, or typically in your rent if you lease.
How It Works
Most neighborhoods on Oʻahu use the three-cart system: gray for regular trash, green for yard waste, and blue for recyclables. Your regular trash gets picked up once a week, while the green and blue carts alternate every two weeks. You can check your specific collection schedule online.
Some areas—usually older neighborhoods with narrow streets—still use manual collection where you provide your own 35-gallon containers. If that’s you, you’ll get picked up twice weekly.
The Rules
Put your carts out by 6 a.m. on collection day, but not before 6 p.m. the night before. Don’t be that neighbor who leaves their carts at the curb all week—bring them back in after pickup. Place them at least five feet away from mailboxes, cars, or anything else that might block the automated trucks.
Oh, and bulky item pickup (furniture, appliances, that kind of thing) is now by appointment only. You can schedule through opala.org or by calling 768-3200.
A Few More Essentials
While we’re talking utilities, let’s cover a couple other things you’ll need:
Internet
Your main options are Spectrum and Hawaiian Telcom. Hawaiian Telcom’s fiber service is faster and more reliable if it’s available in your area—I’m talking 300+ Mbps consistently. Spectrum’s cable internet is solid too and has wider coverage. Expect to pay $30-$50 monthly for basic service, and more if you want higher speeds or TV bundles.
Gas
If you need natural gas (for your stove, water heater, or dryer), Hawaii Gas is your provider. Call them at (808) 535-5933 to set up service. Many homes here use electric for everything, but if your place has gas hookups, you’ll need to establish service. They typically require a $100 refundable deposit.
The Timeline: When to Set Everything Up
Here’s my advice based on actually living through this: start the process at least a week before your move-in date. Call HECO and BWS as soon as you have your move-in date confirmed. Even though HECO says they only need one business day, Murphy’s Law says something will go sideways if you cut it too close.
And if you’re working with a real estate agent to find your place—whether you’re buying or renting—reach out to a local team who knows the area. They can often give you the heads-up about quirks with specific properties or neighborhoods that’ll save you headaches later.
The Bottom Line
Setting up utilities on Oʻahu isn’t rocket science, but it does require a bit of planning. Give yourself enough lead time, have your payment information ready, and don’t be shy about asking questions. The customer service folks at these companies deal with new residents all the time—they’ve heard it all.
Once everything’s up and running, you can get on with the actual business of settling into island life. And trust me, dealing with a bit of utility paperwork is a small price to pay for living in paradise.
