The stretch of coastline in the province of Ravenna is 47 km long and crosses the municipalities of Ravenna and Cervia. However, the quality of bathing water is only monitored for 39 km because, due to the presence of a military firing ground, access and therefore swimming, is forbidden along about 8 km of the coastline in the northern part of Casalborsetti.

As well as Bellocchio canal, numerous other waterways flow into the sea along the coastline of the province of Ravenna.

Reno River
The Reno River is 211 km long and it crosses 3 provinces, Bologna, Ferrara and Ravenna. Its catchment area extends for a total of 4,172 square km and the largest pollution load comes from the province of Bologna. In the last 35 km, the river does not receive any discharge and this means that the river naturally purifies itself. In certain periods of the year, the water is used to supply Ravenna aqueduct. The average flow at the mouth of the river during spring is 57 m³/sec whereas during the summer it is just 8 m³/sec. The values of the parameters indicating organic pollution are not extremely high.

Destra Reno canal
This originates in Lavezzola from Zaniolo drainage canal, which comes from the Imola area. The Destra Reno canal stretches for a total of 37.64 km and crosses almost the entire northern part of the province of Ravenna. Following the old course of the River Lamone, it flows into the sea near Casalborsetti. It receives, either directly or through its tributaries, a lot of urban and industrial waste, in particular agro-alimentary waste. At present, the basin's total urban load is purified for about 80 % of the population. The mouth of the canal is protected by two wharfs, which are about one hundred metres long and channel the waters beyond the breakwater rocks, thus ensuring dilution of any possible pollutants.

Lamone River
The river has its source in Toscana and after 88 km, it flows into the sea at Marina Romea. Once it has been mixed with water from the Emiliano Romagnolo canal, which is channelled into the Lamone River near Pieve Cesato, the river is the main source of water for Ravenna aqueduct. The average flow of water at the mouth of the canal, which is protected by two 90 metre long wharfs, is 8 m³/sec in spring and 1.25 m³/sec during the summer. The water is usually of very high quality.

The Port of Ravenna
Candiano canal, which is the main axis of the port of Ravenna, is protected from the sea by an outer harbour, enclosed by two dams that stretch out to sea for about 3 km. The canal is also connected to two valley expanses of water, Pialassa Baiona to the left and Pialassa Piomboni to the right. Waste from the city of Ravenna, from Russi and from the industrial area of Ravenna, flow into Pialassa Baiona. The particular conformation of the canal connected to the Pialassa and the tides, which provide a notable exchange of water, ensure that the canal naturally purifies itself.

Molino canal
Molino canal, which flows into the sea at Punta Marina, receives water from an agricultural territory of about 24 sq km, as well as rainwater from Lido Adriano. During the bathing season, except under exceptional circumstances, its waters are channelled into the Pialassa del Piombone, thus avoiding direct discharge into the sea.

Uniti Rivers
Montone River and Ronco River, which originate in the territory of the province of Forlì-Cesena, flow into each other at Ravenna. This gives rise to a waterway called United Rivers, which flows into the sea close to the towns of Lido Adriano and Lido di Dante. Near Ravenna, both rivers are banked, so pollutants come exclusively from the area around Forlì. At the mouth of the rivers, the average flow of water is 19 m³/sec during the spring and 2.71 m³/sec. Close to the mouth of the river, the level of pollutants is not usually very high but swimming is forbidden along the coast for 500 m to the north and 150 m to the south.

Bevano Torrent
The basin extends for about 314 sq km, almost exclusively on the plain between the Savio and the Ronco Rivers. About 30% of the basin is in the province of Forlì whereas the remainder is in the province of Ravenna. The torrent receives numerous tributaries that bring both purified and non-purified waste. In the final stretch, the waterway receives waste from the Lido di Classe-Lido di Savio purification plant. During the summer, the water from these plants is partially used for the fertilizing irrigation of the surrounding countryside.

Savio River
The river basin covers about 660 sq km and extends over almost the entire province of Forlì-Cesena. In the plain, the basin dwindles to just a river and flows for 35 km, 20 km in the territory of Ravenna, between artificial banks. It receives the pollution load from the Cesena region and waste water from the towns of Mensa and Matellica, in the Ravenna area. The river flows into the Adriatic between Lido di Classe and Lido di Savio. The average water flow is 10 m³/sec in the spring and 1.4 m³/sec during the summer. In order to safeguard the quality of the bathing waters on the coast close to the mouth of the river, the left bank was extended in 1992 so that the waters from Savio River could flow into the sea beyond the breakwaters.

Cupa Nuovo canal
This is a municipal reclamation canal that began life as a drainage canal for waters from the countryside around Cervia. It receives water from the purification plant in Cervia and during the summer, this is used partially for fertilizing irrigation. It flows into the sea in the resort of Milano Marittima and two, 90 metre long wharfs protect the mouth of the canal.

Cervia canal port
The canal receives water from Cervia salt mines and rainwater from the towns of Cervia and Milano Marittima. It flows into the sea between Cervia and Milano Marittima and two wharfs protect the mouth of the canal.
