Cleaning And Sanitation Services In Urban Or Rural Areas, And Related Services – Service Contract For The Recovery Of The Hydraulic Capacity Of The D-7 Drainage Canal Of Campo De Cartagena. T.T.M.M. Cartagena And Los Alcázares (Murcia).. The D-7 Drainage Channel, Executed By The Segura Hydrographic Confederation, O.A., Aims To Capture Surface Runoff Before It Enters The Urban Area Of ​​Los Alcázares, Intercepting These Waters And Directing Them To The Rambla Del Albujón. The Canal Has A Trapezoidal Section, A Length Of Approximately 4 Km And Is Built On Land, With The Left Side Protected By A Layer Of Breakwater. After Various Interventions To Improve And Expand Hydraulic Capacity, This Infrastructure Constitutes A Fundamental Element In The Defense System Against Floods In Campo De Cartagena And Around The Mar Menor. This Infrastructure Is Of Vital Importance To Alleviate And Divert The Flow Of Water Current That Is Caused By The Episodes Of Torrential Rains That Frequently Occur In The Months Of September And October, So That It Greatly Reduces Runoff To The Urban Area Of ​​Los Alcázares, A Municipality Seriously Affected By These Episodes. During The Year, And Especially In The Periods Of Greatest Vegetative Growth, There Is A Proliferation Of Reeds Of Variable Height Inside The Channel, Both Between The Breakwater And In The Sole And On The Right Slope, In Addition To The Accumulation Of Materials Dragged From Agricultural Activity. All Of This Progressively Reduces The Hydraulic Capacity Of The Channel, Compromising Its Functionality. For These Reasons, It Is Essential To Carry Out Clearing, Sanitation And Cleaning Work Along The Entire 4 Km Route, Guaranteeing That The D-7 Canal Remains In Optimal Conditions To Fulfill Its Mission.
