Application of solar energy to purify the water is advancing rapidly since it is an attractive alternative because of its simple technology; non-requirement of skilled labor for maintenance work, low energy consumption and no fuel is required for operating such water purification unit. This paper deals with the performance evaluation of the solar water purification at Mechanical Engineering Department MMMUT Gorakhpur, India. To perform this experiment, parabolic trough of fixed rim angle and length is considered. Based upon rim angle and length other pertinent parameters are calculated and selection of materials for fabrication of the unit is done. After that solar water purifier unit is fabricated. The solar parabolic collector utilizes the concentrating solar power technology to concentrate the solar insolation. The performance of parabolic trough is evaluated by considering the effect of glass cover on the concentrator. Various results are plotted between the temperature of the fluid and time keeping other parameters held fixed. Further a comparative study is performed for solar water purification unit with and without glass cover. The purity of water is measured based on its pH value and total dissolved solid (TDS).

To make Kenjeran coastal areas as the mainstay tourism Surabaya municipaladministration, provision of clean water is one of the means that must be provided.Construction of sea water purification unit with sea water reverse osmosis method isone solution that can be done. This study aims to assess the feasibility of building awater purifier sea with sea water reverse osmosis method. Finally found that for aninterval of 15 years at an average rate of visitor arrivals tourist attraction as much as7,935 people / day needed clean water supply as much as 257.09 m3 / day, equivalent to10.71 m3 / hour. Average investment value of Rp. 5.5 billion with 19:38% IRR ratemuch higher than bank interest, which is 10%. Break Even Point investment occurred inyear 7 in 2023. Keywords: investment feasibility, Sea Water Reverse Osmosis, coastel tourism area
