Connecticut Utility Connection Costs (2026): Hartford and New Haven
Connecticut’s two cities covered here price a new water and sewer connection in very different ways. In Hartford, the Metropolitan District (MDC) lists a fixed $910 for a standard water tap and meter, then assesses water at $95.00 per foot and sewer at $111.50 per foot of property frontage. In New Haven, the Regional Water Authority (RWA) and Greater New Haven Water Pollution Control Authority (GNHWPCA) publish a combined $5,060 base for the standard meter, plus an unpublished saddle cost and potentially a main-frontage charge. These are documented charges for particular assumptions, not interchangeable all-in construction prices. Only these two Connecticut cities are covered so far.
Official fees in Connecticut
The table lists verified fee rows for the two cities and links each row to its source. Hartford’s assessment depends on the frontage MDC establishes for the parcel; New Haven’s published base depends on meter size and on whether a separate main-related charge applies. Check the city pages before using any row as a budget.
| City | Provider | Water typical new home* | Sewer typical new home* |
|---|---|---|---|
| Hartford | The Metropolitan District (MDC) | $360 | — |
| New Haven | Greater New Haven Water Pollution Control Authority (GNHWPCA) | $895 | $3,850 |

City comparison
Published water and sewer charges for a new single-family connection, under each city’s stated assumptions.
| Situation | Hartford | New Haven |
|---|---|---|
| Standard connection | $910 fixed tap and meter, plus $95.00/ft water and $111.50/ft sewer assessments | $5,060 base, plus unpublished saddle cost and any applicable main charge |
| Illustrative or alternate case | $9,170 for the city page’s illustrative 40 ft frontage | $6,845 with a genuine 3/4-inch capacity meter, plus saddle cost |
The Hartford worked example builds the 40-foot case from $3,800 water assessment + $4,460 sewer assessment + $550 water service tap + $360 meter = $9,170. Its 60-foot and 100-foot illustrations total $13,300 and $21,560. Those widths are examples, not published typical Hartford parcels. MDC calculates a property’s assessable footage from its records; its permits information also says sewer assessments may use acreage and/or dwelling units in some cases. An address-specific MDC determination is necessary before treating an illustrated total as a quote.
The New Haven worked example uses a 5/8-inch meter and RWA’s minimum 1-inch service tap. Its water side is $630 local facilities + $315 corporation-stop connection + $265 meter installation = $1,210. Add GNHWPCA’s $3,850 sewer connection permit and the published base is $5,060. RWA’s tap schedule adds the cost of a saddle based on main size but gives no flat amount. A genuine 3/4-inch meter raises the GNHWPCA charge to $5,635, making the base $6,845; the RWA charges in that case remain $1,210. When RWA requires a 3/4-inch meter only for reading, the New Haven page says GNHWPCA retains the lower 5/8-inch fee.
The comparison is therefore about two different billing structures. Hartford’s illustrative total includes lot frontage and a meter but does not establish a statewide or even citywide typical bill. New Haven’s base includes named water and sewer authority charges, while leaving a site-specific saddle cost outside it. RWA may also assess a Proportionate Share charge when the serving main was installed at RWA expense or under a developer’s Advance Payment Extension Contract. That charge follows actual main cost and frontage rather than a published flat rate. Both places also leave private construction out of the displayed totals.
What decides your number
- Frontage and main history. MDC assesses Hartford water and sewer connections using the property’s records; RWA can impose a separate proportionate-share charge for qualifying New Haven main installations. Ask the serving authority what applies to the parcel.
- Meter and service size. Hartford’s example combines a 1-inch tap with a 5/8-inch meter. New Haven’s standard example also uses a 1-inch service tap, but GNHWPCA’s sewer permit changes sharply when a 3/4-inch capacity meter is required.
- Unpriced work. Hartford’s charges do not pay for the private water line, sewer lateral, excavation or city permits. New Haven likewise excludes the customer-installed water service, sewer lateral, trenching and city permits. Neither table is a contractor quote.
- Published schedule limits. MDC has another meter installation table with a different price for the same size meter; the Hartford page explains why its new-connection example uses the Domestic & Fire Meter Cost table. The New Haven sewer connection schedule has not been revised since July 2022, according to the city page, so confirm the current charge with GNHWPCA.

Frequently asked questions
What is a typical water and sewer connection total in Hartford?
MDC’s flat tap and meter charges total $910 in the documented example, but water and sewer assessments depend on the property’s frontage. The Hartford page illustrates $9,170 at 40 feet; it does not claim that frontage is typical. MDC must determine the property-specific assessment.
What does the New Haven base total include?
The $5,060 standard-meter base combines $1,210 in RWA water charges and a $3,850 GNHWPCA sewer permit. It excludes RWA’s unpublished saddle cost, any applicable Proportionate Share charge and private line work. See the New Haven breakdown.
Does meter size change the fee in both cities?
New Haven’s GNHWPCA sewer permit changes with capacity meter size: the documented base is $5,060 with a 5/8-inch meter and $6,845 with a genuine 3/4-inch meter, before the saddle. Hartford’s displayed examples change mainly with frontage; its city page lists size-specific tap and meter rows separately.
Are private water and sewer lines included?
No. Both city pages separate official connection charges from private service line, lateral and excavation work. Ask the authorities for applicable fees and a contractor for the work on the lot.
