RESEARCH ON THE FEASIBILITY OF TECHNICAL – INVESTITION SOLUTIONS OF DRAINAGE SYSTEM RECONSTRUCTION

Abstract

From  the  technical  and  agro-technical  point  of  view,  the  reclaimed  land  of poor  condition  covers  222.4  thousand  ha.  More  than  15.0  thousand  ha  of  drained agricultural land turned into a swamp, more than 67.3 thousand ha overgrew with bushes  and  forest.  The  average  depreciation  of  buildings  reached  59.1  percent. When drainage structures are  worn  down,  there is a  need to  overhaul  or,  in  many cases, to reconstruct them.

The  economic  situation  in  the  country  and  farming  agricultural  conditions change,  therefore  it  is  appropriate  to  assess  drainage  systems  from  the  economic viability  and  payback  time  of  the  projects  viewpoints,  using  a  variety  of  partial drainage  and  surface  water  drainage  ways,  depending  on  land  use.  Drainage  sys-tems  should  be  reconstructed  in  areas,  which  are  used  in  agricultural  production, therefore  agricultural  output  prices,  state  and  EU  subsidies  as  well  as  profits  per unit  of  area  are  key  indicators  that  determine  economic  viability  of  the  drainage system reconstruction project.

Drainage  system  reconstruction  clients  are  municipalities,  land  reclamation business associations and, in rare cases, farmers or other individuals, their goal - to get the maximum profit at the lowest possible cost. Considering the expected activ-ity,  simple  solutions  are  often  enough,  therefore,  the  reconstruction  of  drainage systems  should  be  designed  allowing  a  wider  choice  of  cost-effective  technical solutions.

Research objective - to investigate technical options for the reconstruction of drainage  systems  allowing  achievement  of  the  expected  economic  benefits  of  the project.
