    30. 30 Benefit Estimation Travel Cost Model Contingent Valuation Model

    31. 31 TCM 300 surveys at the site (Dec. 2005 – March. 2006) Used to estimate only Use-value. Only 2005 situation. We used two sub-models Zonal travel cost Individual travel cost (will not be described here but was done).

    32. 32 Step 1: ZTCM base table

    33. 33 Step 2: Visitation against price increase

    34. 34 Step 3: Fitting a function

    35. 35 Step 3 (cont.) Total benefit of the site: (MNIS per year) Linear function: Visits =65577-157.32*(Travel Cost) TB=15,471,164 Cubistic function: Visits = 96554.5 – 796.7*TC + 2.3 (TC)2 – 0.0022 (TC)3 TB=10,268,534 Exponential function: Visits =[6.504756-ln(Travel Cost)]/0.00008426 Travel Cost =668.3*exp{-0.00008426*(Visits)} TB=7,929,665

    36. 36 CVM (In process) 300 surveys (200 at the site + 100 sample of general effected population) Payment card Can estimate Use + nonuse values Can estimate future hypothetical scenarios - We asked about future water quality improvement which can be thought of as almost usable for every purpose

    43. 43 Zeimar – Alexander basin The comparison between the years 1995 – 2005 focuses primarily on the four following points: Many secondary pollution sources were eliminated Natanya’s wastewater treatment facility Kubani Creek Wadi Zeimar.

    57. 57

    58. 58 Wastewater Treatment Options Three different scenarios were evaluated for wastewater management within the Wadi Zeimar catchment area involving: 1. Primary treatment at Tulkarem pools only (BAU Scenario), No additional Costs except for O&M 2.1 Extended Aeration Treatment and Reuse System at Tulkarem only (Expected Future Scenario #1.1), 40 million US for the first phase and about 31 million US$ additional funds needed until 2030 2.2 Activated Sludge Treatment and Reuse System at Tulkarem only (Expected Future Scenario #1.2) 41 million US for the first phase and about 32 million US$ additional funds needed until 2030 3. Activated Sludge or Extended Aeration Treatment and Reuse System plus advanced treatment at Tulkarem and Nablus-West (Expected Future Scenario #2), 100 million US for the first phase and about 80 million US$ additional funds needed until 2030

    60. 60 Extended Aeration – Two Stage Plant Cost

    61. 61 Activated Sludge, Tulkarem Two Stage Plant Cost

    62. 62

    63. 63 Annual O & M Costs Ranging from 1,500,000 US$ in 2016 to 2,750,000 US$ in 2030 Distributed as : Wastewater treatment plant, % 80 Effluent Distribution and Reuse Sys,% 5 Wastewater Collection Sys, % 15
