Larnaca is preparing to implement one of the largest infrastructure projects in recent years. Construction will soon begin on an underground stormwater drainage network covering the central district around Grigori Afxentiou Avenue. The project has strategic importance, aiming to collect and safely channel rainwater to the sea using natural gradients, eliminating the flooding issues that affect Larnaca during heavy rains.
Project Scale and Technical Features
The future network will stretch for 2.7 km, with all pipelines installed underground. Work will cover the streets of Grigori Afxentiou, Makariou, Lord Byron, Athinon, and Kiti. The endpoint will be the existing pumping station south of Larnaca Marina, from where water will be discharged into the sea via a concrete collector measuring 2.2 × 2 m.
Excavation depth will reach 3.3 m. Pipes and manholes will be made of reinforced concrete to ensure system durability and stability. Construction will involve removing sections of road pavement, trench installation, backfilling, installing manholes, followed by full restoration of the roadway.
Safety Measures and Environmental Responsibility
Since the groundwater level in the Finikoudes area is only about 70 cm, the project includes active dewatering of construction trenches. Pumps and settling tanks will be used to clean the water before it is discharged into the sea, away from beaches, to maintain the ecological purity of the coastal zone.
All construction waste will be sent to licensed disposal centers. As the works will take place within the urban area, the project will not affect natural ecosystems or coastal zones.
Impact on the City and Measures to Minimize Disruption
The works will affect the central part of Larnaca, where schools, museums, clinics, hotels, and commercial properties are located. Temporary inconveniences for residents will include noise, dust, and changes to traffic flow.
The municipality has implemented a comprehensive set of measures to minimize the impact. These include:
- Installation of noise barriers
- Fencing of construction sites
- Organization of safe pedestrian routes
- Performing major works during school holidays
To speed up the process, contractors will be required to limit the length of trenches open at any time to 100 meters, reducing the duration of construction equipment in each area.
The project affects historic quarters within the ancient city of Kition. Although there will be no direct interference with archaeological layers, specialists from the Department of Antiquities will be present at all excavation stages to prevent damage to cultural monuments and document any finds.
Prospects and Significance for Larnaca
After the tender procedures, scheduled for early 2026, construction is expected to last approximately 18 months. By 2027, the city center of Larnaca will be reliably protected from seasonal flooding.
The new stormwater drainage system will not only ensure the safety of residents and tourists but also lay the foundation for further urban infrastructure development, increase the investment appeal of the region, and improve quality of life.
