Sarroch, the coast south-west of Cagliari and the refinery

On the SS195 state road, which runs down the coast from Cagliari towards Pula, Sarroch is the town many people know for the Saras oil refinery, one of the largest industrial sites in Sardinia, facing the Gulf of Cagliari. The village itself lies a little inland at the foot of the hills, and the municipality also contains the Antigori nuraghe, a Bronze Age stone tower known to archaeologists for its finds of Mycenaean pottery.

For buyers, the refinery is the first thing to weigh up. It employs many people from the area, but anyone choosing a house near the industrial zone should look at the external emergency plan, which for plants of this kind is drawn up by the Prefecture (the local office of the national government), and at the distance from the site. Elsewhere in the municipality there are detached houses, homes with a yard and some country properties; Cagliari remains the reference for hospitals, the university and public offices.

In 2023 there were 5,008 residents, down 3.7% on 2011, according to Istat, the national statistics office. The average age is 49.5, against 48.1 in the province, and 28.2% of residents are over 65. Foreign nationals make up 2.7% and households have 2.11 members on average. Average declared incomes are below the provincial average.

In Sardinia, earthquake risk is low. Sarroch is in seismic zone 4, like the other 69 municipalities in the province of Cagliari, with an expected ground acceleration of about 0.050 g. Near the sea, salt and damp on render, reinforcing steel and window frames matter more.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps here and the report finds the land parcel from the address. The streams coming down from the hills to the coast can rise quickly in heavy rain, so flood hazard, like landslide hazard, is checked for the individual address.

Key points

  • Coast south-west of Cagliari, home of the Saras refinery.
  • 5,008 residents, down 3.7% since 2011.
  • Average age 49.5, over-65s at 28.2%.

Overview

Sarroch is a municipality in the province of Cagliari, in Sardegna. At the end of 2023 it had 5,008 residents, ranked 20 of 70 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Sarroch is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 70 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.050 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.

Population

Compared with the 2011 census, the resident population has fallen by 3.7%. The estimated average age is 50 years, in line with the province. 28% of residents are over 65 (the regional figure is 27%). Foreign residents make up 2.7% of the population. On average, a household has 2.1 members.

Income and climate

In tax year 2024, taxpayers in Sarroch declared an average taxable income of 22,580 euros, below the provincial average (24,865 euros). The Italian average is 24,895 euros.

Sarroch is in climate zone C, with 999 heating degree days: heating may be switched on from 15 November to 31 March, for up to 10 hours a day. The same table puts the town hall at 47 metres above sea level.

Public transport

We do not yet have open public transport timetables for this municipality: the report says so explicitly, without inventing distances.

How built-up it is

Buildings, roads, car parks and other sealed surfaces cover 8.6% of the land in Sarroch, compared with 3.4% in the region. In 2024 built-up land grew by 1.7 hectares.

Radon and contaminated sites

Sarroch is not among the radon priority areas designated by the Regione Sardegna in 2022. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Sarroch: the report checks the address against the ISPRA maps.

House prices

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.

Land registry

The cadastral maps for Sarroch are public: from the address the report finds the sheet and parcel number.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 34 inhabited census areas in Sarroch. Half of the residents live in areas scoring 81 or more.
