Chami Rokhana dam is a mixed embankment-concrete dam.
The embankment dam typical cross section can be described as follows:
• dam crest elevation: 472.00 (m a.s.l.)
• minimum foundation elevation (core bottom): 441.00 (m a.s.l.)
• upstream and downstream face slopes (vertical/horizontal): 1:3 (-)
• overall embankment volume ~600,000 (m3)
The concrete dam typical cross section can be described as follows:
• Rankine triangle vertex elevation 469.00 (m a.s.l.)
• minimum foundation elevation (cutoff bottom): 438.00 (m a.s.l.)
• upstream face slope (horizontal/vertical) 0,1:1 (-)
• downstream face slope (horizontal/vertical) 0.75:1 (-)
It presents two typical cross section: a nonovertopping cross section (26.30 m) and an overtopping cross section (140.40 m). Nonovertopping cross section, of gravity type, is characterized as follows:
• dam crest elevation: 472.00 (m a.s.l.)

In the Chioggia area, work to secure dumps has involved the former Val da Rio dump created between 1964 and 1984 with dumping of more than 500,000 m³ of waste. Erosion caused by wave motion and wash on the banks, dispersion through the sandy layers and rainwater leaching have led to dispersion of pollutants into the surrounding environment, making the need to secure the 7 ha area a matter of urgency. Work consisted largely of sealing the entire perimeter of the dump by installing a plastic membrane, metal sheet piling or both depending on the characteristics of the various areas. Complementary measures have also been completed to secure the area between the dump and the port.

Description of the activities
1 – Strengthening of civil line
Improve Civil capacity that, during rainy period, reaches values in the order of 24,000 – 25,000 m3 / d, with the need to spillway (authorized) in the Canal. New supply of wastewater from Paper Mill Chiampo (active since 2012).
Future contribution (from 2016) to the treatment plant (yet to be determined in which line of treatment) of the first rain water of open areas of the companies listed in Annex F of the PTA.
2 – Optimization of the industrial line
Rationalization of the No. 1 line of the oxidation sector (No. 6 tanks for a total of 56,000 m3) aimed at ensuring safety and energy saving. Tertiary treatment of effluent – Effluent Improvement of SST and Chrome quality. Reuse (partial) of the effluent of the civil line as civil service water for the plant.
