Two homes a mile apart in Grants Pass can run on completely different systems. One pays a city water and sewer bill; the other draws from its own well and drains to a septic tank in the yard. The line between them follows the city’s urban growth boundary, and it shapes your monthly bills, your inspections, your loan paperwork and what you can build on the lot.

The Urban Growth Boundary Sets the Line

Grants Pass supplies water and sewer inside its urban growth boundary, the line the city and state draw around land planned for city growth. Oregon’s land use rules keep city sewer off rural land, and the city’s water plan serves customers inside the boundary. Outside it, homes run on private wells and septic systems. The one exception sits five miles north, where the city pipes water to a small area between Merlin and I-5, including the North Valley Industrial Area and Paradise Ranch.

Where City Service Ends on Each Main Road

Checked against the state’s boundary map in October 2026, city service ends near these points:

• Redwood Highway (US 199): Southgate Way, past College Drive and Rogue Community College
• Lower River Road: Schaefers Lane and Roguelea Lane
• Upper River Road: Rogue River Loop Road
• Leonard Road: S River Road
• Williams Highway (Hwy 238): Fairway Drive and Espey Road
• New Hope Road: Allen Lee Road, near Allen Creek Road
• Rogue River Highway (Hwy 99): Fruitdale Drive
• Foothill Boulevard: Ament Road, by I-5
• Highway 99 and I-5 north: Monument Drive and Highland Avenue
• NW Scenic Drive: Vine Street

Homes in Merlin, Wilderville, Murphy, Williams and New Hope run on wells and septic, apart from the small North Valley area the city serves. The city is reviewing its boundary for expansion, so the line can move.

Some Homes in Town Still Run on Wells

A home inside the boundary, or even inside city limits, can still draw from its own well. Much of the Fruitdale area in southeast Grants Pass was built before city mains reached it and still runs on private wells, and the Rogue Community College campus on Redwood Highway has its own wells (City of Grants Pass Water Master Plan, 2016). Harbeck-Fruitdale has its own sanitary district, which contracts with the city to treat its sewer.

For any specific address, three sources settle the question: the listing’s water and sewer fields, the seller’s disclosure statement, and Grants Pass Community Development at (541) 450-6060.

What a City Hookup Costs

A home inside the boundary but outside city limits can connect to city water when a main already runs along its frontage. The owner pays the connection charges and signs a Service and Annexation Agreement, which consents to future annexation by the city. Without a signed agreement, a water customer outside city limits pays a 60% surcharge on every water bill.

New connections also pay system development charges, the city’s one-time fee for capacity in its water and sewer plants. For a single-family home with a standard 3/4-inch meter, the 2026 water and sewer charges together come to $6,567 for a home of 1,700 square feet or less, $9,661 for 1,701 to 2,900 square feet, and $13,234 above 2,900 square feet. The physical hookup adds $3,185 for a 1-inch service line from a paved road, plus street restoration, a plumbing permit and a small river crossing fee south of the Rogue. Where no main reaches the property yet, the owner pays to extend one.

Buying a Home on a Well

Once a seller accepts an offer on a home with a domestic well, Oregon requires a lab test for arsenic, nitrate and total coliform bacteria, with results sent to the buyer and the Oregon Health Authority (ORS 448.271). A buyer can’t waive the test, and results stay valid for one year from the sale.

That test covers water quality. Quantity is a separate question, answered by a flow test during the inspection period, and a well that runs strong in April can slow by September. The Oregon Water Resources Department keeps a drilling log for most wells, with the date, depth and flow when drilled; Josephine County wells run a median depth of about 126 feet.

A household well needs no water right for household use up to 15,000 gallons a day and a lawn or noncommercial garden up to half an acre. Irrigating pasture, filling a pond or farming takes a recorded water right. Drilling a new well runs about $25 to $60 a foot in the Grants Pass area (2026 local cost estimates), before the pump, pressure tank and hookup.

Buying a Home on Septic

Oregon DEQ’s Medford office permits septic systems for Josephine and Jackson County, from site evaluation to repair: (541) 776-6010. Where the ground can’t support a standard gravity drain field, because of a high water table, poor soil or a nearby waterway, the site needs an aerated treatment unit or an engineered system. Those run $20,000 to $40,000 installed, and an aerated unit needs power, an alarm panel and a yearly maintenance contract of about $250 to $450.

USDA loans require a septic inspection before closing, and any buyer can order one. A documented, recently serviced system passes cleanly; one of unknown age can need records or repairs before closing.
