Setting up utilities in Flower Mound, TX involves more than just flipping a switch on move-in day.
Key Takeaway
The simplest setup in Flower Mound is Town water, sewer, and trash, paired with electricity over Oncor's lines where you choose your own retail plan. The alternative to plan for is an address on CoServ, which rules out plan shopping, or one on a private well and septic system, which adds testing and inspection costs a Town bill would have covered. With 3.1 months of housing supply for the 90 days ending September 30, 2026, there is usually time to confirm providers and request a year of bills before the option period ends.
Who This Guide Is For
You are buying, selling, or renting a home in Flower Mound and need to know which companies serve that address and what to check before you sign or close.
Who Provides Utilities in Flower Mound?
In Flower Mound, the utility question that changes your bill and your inspection list is which service territory an address falls in, not which retail electricity plan you pick. You'll find three main splits across town:
Electricity comes from either Oncor or CoServ.
Gas comes from Atmos or CoServ Gas.
Water comes from the Town system, another provider, or a private well and septic setup.
Most of your monthly costs and inspection risks follow from those splits, so check official service maps for your exact street.
To find your next steps, answer four questions:
Is the address in Oncor's service area or CoServ Electric's? If Oncor, read the section on comparing electricity plans. If CoServ, skip plan shopping and read the CoServ Electric section.
Does the house have a Town water meter, or a well and septic system? A Town meter points to the Town water section; a well or septic tank points to the well and septic section.
Is there a gas meter, and whose name is on it? Read the natural gas section, or the all-electric section if there is no meter.
Are you buying or selling, and when is closing? Buyers go to the setup section, sellers to the transfer section.
When you build your overall household budget and cost of living, use the seller's actual bills for these lines rather than an area average.
Electricity in Flower Mound
Who owns the lines to your house decides whether you shop for power at all. In the Oncor area, you choose a retail provider and own the risk of picking a bad plan. In the CoServ area, the cooperative sets the rate and you can't shop for alternatives.
Oncor Service Area
Oncor owns the poles, wires, and meters for a large portion of the town and handles power outages. Your retail electricity company doesn't. If your home sits in Oncor's territory, you buy electricity from a retail provider you select. The seller's plan doesn't carry over, so you'll need a new account. A plan that rolls to a variable rate after its contract ends can raise the bill without warning, so note the end date of anything you sign.
CoServ Electric Service Area
CoServ is a member-owned electric cooperative serving parts of Denton County, including sections of Flower Mound. Addresses in its territory buy power from CoServ directly and don't use the state's Power to Choose website. Check the specific address on CoServ's interactive GIS service map rather than assuming coverage based on the neighborhood. With no plan to switch to when rates rise, your only control over the bill is usage.
How to Compare Electricity Plans
In the Oncor area, use the Public Utility Commission of Texas's Power to Choose website to compare retail electric plans. Under state rules, every provider must give you its Electricity Facts Label (EFL) on request. The label standardizes pricing and contract terms so you can compare options fairly.
Compare the label's price at the usage level shown on the seller's summer bills, not just the 1,000 kWh headline rate. Plans with bill credits can look cheapest at exactly 1,000 kWh and cost more at the higher summer usage a large home runs. Check the contract length and the early termination fee before you sign.
Town of Flower Mound Water, Sewer and Trash
Homes on Town service get water, sewer, and trash on a single monthly statement, and the Town maintains the underground infrastructure. The rules that come with it set your lawn watering schedule and your bulk and brush pickup.
Where Flower Mound Gets Its Water
The Town buys treated surface water from the Upper Trinity Regional Water District and Dallas Water Utilities and delivers it to residents and businesses. Because supply depends on regional sources, the Town can tighten outdoor watering in dry periods, which affects lawns and new landscaping.
Water and Sewer Rates
For the 2026-2027 fiscal year, the residential minimum water bill is $28.53, with usage over 2,000 gallons charged at $5.80 per 1,000 gallons. The residential sewer charge is based on your winter-average usage. Summer irrigation is what usually pushes a summer statement well above a winter one. Ask whether the home has a separate irrigation meter and check its controller settings.
Watering Schedule and Drought Rules
The Town's Long-Term Water Conservation Plan bars automatic irrigation and hose-end sprinklers between 10 a.m. and 6 p.m.:
Residential addresses ending in an even number may water on Tuesday and Friday.
Odd-numbered addresses water on Wednesday and Saturday.
Hand-held hoses, drip irrigation, and harvested rainwater are permitted at any time, though emergency stages can add more restrictions.
These limits can make new sod or a re-landscaped yard hard to establish. Check the current drought stage before planning heavy yard work after closing. Violating the schedule can result in municipal fines.
Trash and Recycling Pickup
Republic Services provides weekly residential trash, recycling, and bulk and brush removal, billed through the Town. For the current fiscal year, the service costs $20.40 plus tax per month. That covers semi-automated trash collection, single-stream recycling, and weekly bulk pickup of up to four cubic yards. Homeowners associations may add rules on cart placement and storage, so ask the HOA before move-in.
Addresses Served by Another Water Provider
Some properties at the Town's edges or in separate utility districts get water from a provider other than the Town. Confirm the provider through the Town's service area information or by asking the seller. A different provider means different rates, rules, and billing office. Assuming the Town bill applies can leave you with unexpected setup fees or higher usage rates.
Well Water and Septic in Flower Mound
A private system trades the monthly Town water bill for owning testing, pump repairs, and septic upkeep yourself. Wells and septic systems turn up mainly on the larger-lot and older properties among Flower Mound's home types and lot sizes.
Where Wells and Septic Systems Still Exist
Listings don't always state the water source in the public remarks. You may not learn a property relies on septic until you review the seller's disclosure or walk the lot, so look for these features deliberately when browsing acreage.
How to Tell If a House Has Well or City Water
Look for these clues:
A water meter box near the street, a pressure tank, or a well head near the house.
The water supply section of the seller's disclosure, or a recent water bill.
Visible tank lids or a drain field in the yard, which usually point to a septic system.
Setups can be mixed. A home might have Town water but a septic system, and some properties keep an old well for irrigation. Verify the water source and the sewer method separately.
Well Costs vs a Town Water Bill
A well removes the municipal water bill but adds pump electricity, water testing, and eventual equipment repairs. Those costs come in lumps: a pump failure arrives as one large bill. The Texas Well Owner Network recommends testing private wells at least once a year for bacteria, nitrates, and local contaminants. Get local quotes for water treatment if tests show hard water or mineral buildup.
Septic Inspections and Permits
On-site sewage facilities are permitted through local authorities. Request the permit file to see the system's age and design capacity. Older systems may have thin or missing records, which makes an inspection by a licensed septic professional during your option period your main evidence of condition.
Switching from a Well to Town Water
Connecting to Town water requires a nearby Town water main and payment of connection and impact fees. The Town won't furnish a meter until impact fees are paid in full. Cost depends on how far the nearest main is from your property line, and in some rural spots a connection isn't available at all. Ask the Town's utility or engineering departments for an address-specific answer.
Natural Gas in Flower Mound
As with electricity, your street address sets the gas provider. You use whichever company owns the pipes, with no rate shopping. Some homes have no gas service and run entirely on electricity.
Atmos Energy
Atmos Energy serves many addresses across town and the broader Denton County area. Contact Atmos to confirm it serves the address and to put billing in your name. Allow time before closing for any deposit or credit check.
CoServ Gas
CoServ Gas serves some addresses, most often in newer developments. Run the address through CoServ's service map rather than guessing from the subdivision. CoServ's gas rate can differ from what Atmos charges a few streets over.
All-Electric Homes
Some properties have no gas meter and rely on electricity for heating, cooking, and hot water. Check the exterior walls for a gas meter and confirm the setup with the seller. Winter heating lands on the electric bill in these houses, so ask for the seller's winter electric bills as well as the summer ones.
Internet Service in Flower Mound
The type of connection, whether fiber, cable, or satellite, depends on which companies have lines to your street. Availability can change by the block.
Fiber and Cable Providers
The FCC National Broadband Map shows which providers report service at an address. The map relies on what providers report, so a listed provider may not reach the specific house.
How to Confirm Service at an Address
Run the full street address through each provider's availability check. Ask the seller who they use and how the connection performs at peak hours. Installation dates can lag behind move-in, so if you work from home, book an installer early.
Setting Up Utilities When You Buy in Flower Mound
Your window to check utilities opens when the contract is executed. The option period in the buying process is when you can still walk away if a septic system fails inspection or a well needs a new pump. Michael Hershenberg can help buyers coordinate these specialized inspections before the clock runs out. The timeline for buying a home in Flower Mound outlines when to complete these steps.
Confirm Providers Before the Option Period Ends
During the option period, confirm your electricity territory, gas provider, water source, and any well or septic systems. Check your contract for the option period's exact length. Flower Mound housing market trends show homes recently sold at a median 98.4% of list price (90 days ending September 30, 2026), so there's little room on price later in the transaction. After the option period ends, a septic or well problem you didn't check becomes your cost.
Ask the Seller for 12 Months of Bills
A full year of electric, water, and gas bills shows the summer cooling peak and winter heating low for that house. It's the most reliable budget figure available before you move in. The totals reflect the seller's household size, pool use, and thermostat settings, so treat them as a baseline, not a guarantee.
Expect Deposits and Credit Checks
The Town, retail providers, and co-op providers may require a deposit or credit check to open an account. To start residential water and sewer service, the Town requires a completed application, a $60 deposit, and a $15 service fee.
The deposit is held until you make 12 consecutive months of on-time payments with no returned checks, then credited to your account balance. A qualifying letter of credit from a prior utility provider can waive it. Under the Town's ordinances, a required deposit may not exceed one-sixth of the prior 12 months' billing at that service location. Deposits tie up cash at the same time closing costs are due.
Read the Meters at Closing
Photograph the electric, water, and gas meter readings on closing or possession day. That way your first bill starts from the right number and you don't pay for the seller's final days. As part of your moving logistics, schedule each account to start on possession day. If the seller stops service before your account activates, you may face a gap without power or water, and restoring service often brings reconnection charges.
Transferring Utilities When You Sell in Flower Mound
In the selling process, stop dates come after funding. Cutting power or water too early can leave the buyer's walkthrough without lights, air conditioning, or running water. That can delay closing if the buyer can't verify the appliances work. A clean handoff protects your deposit refunds and keeps you from being billed after you hand over the keys.
Set Stop Dates After the Sale Funds
Flower Mound homes recently took a median of 37 days on market (90 days ending September 30, 2026), which typically leaves several weeks to line up stop dates. Keep every service on through the buyer's final walkthrough and until the sale funds.
Final Bills and Deposit Refunds
Give each utility a forwarding address for your final statement. Deposits are typically applied to the final bill or refunded by check, but ask each provider how its refund works. Close out any separate irrigation meter too. A forgotten meter or outdated address can leave a final bill unpaid and send the account to collections.

Flower Mound Utilities FAQs
Are Utilities in Flower Mound Expensive?
It depends on usage and providers. Summer irrigation drives the Town water bill, and electricity costs depend on Oncor or CoServ territory, so the seller's last 12 months of bills are the best guide.
Are Flower Mound Utilities Public or Private?
They're a mix:
Water, sewer, and trash are run or contracted by the Town.
Electricity comes from CoServ, a member-owned cooperative, or from a retail provider you choose over Oncor's regulated wires.
Natural gas comes from investor-owned Atmos Energy or CoServ Gas.
What Is the Phone Number for Flower Mound Utility Billing?
The Town's utility billing phone number and office hours are listed on the official website, flowermound.gov.
Is Flower Mound Tap Water Safe to Drink?
Yes. The Town's 2024 Water Quality Report found the drinking water met or exceeded all established standards, and the Town tests it regularly and reports results to the EPA annually. Homes on a private well need their own testing.
Who Do I Call for a Power Outage in Flower Mound?
Call the company that owns the wires, not your retail provider. In Oncor's territory, call 888-313-4747, text "OUT" to 66267, or use the online outage map, which refreshes every 10 minutes. In CoServ's territory, contact CoServ directly.
Does Flower Mound Charge a Stormwater Fee?
Yes. The fee is based on each parcel's impervious surface area, with each residential class equal to one Equivalent Residential Unit (ERU) of 5,285 square feet. Non-residential and multifamily properties paid $6.50 per ERU per month in the 2025-2026 fiscal year.
How Far Ahead Should I Set Up Utilities in Flower Mound?
Apply for Town water and sewer as soon as you have a firm closing date, since the application and deposit take time to process. Electricity, gas, and internet each have their own lead times, so check with each provider during the option period.
Does Flower Mound Offer a Utility Discount for Seniors?
Residents 65 and older pay a discounted $18.22 plus tax per month for trash, recycling, and bulk pickup. Ask the Town utility office about other discounts, and your electric and gas providers about their assistance programs.
