Acqui Terme, the Bollente spring and the Brachetto hills

In the main square of Acqui Terme the Bollente rises, a hot sulphurous spring that has shaped the town for two thousand years. Acqui stands on the Bormida river in the Alto Monferrato; across the river, near the arches of the Roman aqueduct, is the Bagni district with the spa establishments. All around, the hills are planted with Brachetto and Dolcetto vines.

It is the largest town in the Acqui area and the place a wide stretch of hill country relies on for schools, the hospital and shops, but it is some way from the provincial capitals: Alessandria, Asti and Savona are forty minutes or more by road. The station has regional trains to Alessandria and Genoa. Buyers will find period buildings and flats in the centre, detached houses on the edges and farmhouses in the hills, the latter often needing restoration.

The population is old and shrinking: 18,972 residents at the end of 2023, down 5.4% since 2011 according to Istat, the national statistics office, with an estimated average age of 50.0 and over-65s at 31.2%, more than in a province that is already elderly. Households average 1.96 people, a sign that many live alone, and foreign nationals make up 11.4%. Declared incomes are a little below the provincial average.

The earthquake picture is calm. The province of Alessandria has 127 municipalities in zone 3 and 60 in zone 4 of the Civil Protection Department's classification; Acqui is in zone 3, with an expected ground acceleration in the built-up area of about 0.056 g, a low value. In older houses, roofs, facades and systems matter more, and with the cold winters of climate zone E heating weighs on running costs.

The Bormida and the streams coming off the hills have flooded low-lying areas more than once, and the marl slopes of the Monferrato are prone to landslides. The report checks both hazards for the address, after finding the land parcel on the Revenue Agency (Agenzia delle Entrate) cadastral maps.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.
