Specifically,  the  study  involves  primary  and  secondary  data  collection from  the  study  site  related  to  production  cost  of  rice  farmers,  yield  of  rice  production, climates,  soil  type,  crop  calendar,  and  the  rice  marketing  channelsystem  of  Suphan  Buri province. The amount  of  irrigation  water  applied  in  paddy  field  was  used  CROPWAT  8.0 model in  estimation  then  used  this  amount  to  calculate  the  value  of  irrigation  water  using the  Residual  Imputation  Method  (RIM).  Results  show  that  the  average  value  of  irrigation water  had  contributed  into  2  cases.  For  case  without  government  subsidy,  the  value  of irrigation  water  is  0.017  US$/m3and  0.019  US$/m3for  dry  and  wet  season,  respectively. For case with government subsidy, the value of irrigation water is 0.033US$/m3and 0.045US$/m3for dry and wet season, respectively.In addition,thecost of irrigation project was based  on  Sam  Chuk  O&M  project  investment.  Results  show  that  the  average  cost  of irrigation  water  service  per  area  is  140.95  US$/ha/year  or  in  form  the  mass  unit  of  paddy production  is  13.063  US$/ton  and  13.477  US$/ton  for  dry  and  wet  season,  respectively.Moreover, theadded  value  of  paddy  production  is consideredat  the  primary  milling process  that  consistedbrown  rice  bran,  husk,  white  rice  bran  and  broken  white  rice.In addition,  milling  process  of  white  rice  1  ton had  usedthe  material  production  or  paddy  2 tons.  Therefore,  the  added  value  of  by-productfrom  milling  process  is 138.433  US$/ton. Moreover, the  total  paddy  production  for  each  season is  around  50%  that  is  940,000  tons and  950,000  tons  for  dry  and  wet  season,  respectively.  Therefore,  90%  of  white  rice production in  Suphan  Buri  province  is  selling  to export  market  and  another  10%  is  selling to domestic market.In concludethe new finance irrigation serviceto cover irrigation water service  and  maintenance  costs  is  provided  by 4  scenarios  from the  output  that  mention above.  This  is  only  scenario  of  sharing  cost  of  irrigation  water  service.
