Title: The effects of the implementation of grey water reuse systems on construction cost and project schedule
Author: Kaduvinal Varghese, Jeslin
Abstract: One of the factors emphasized by Leadership in Energy and Environmental Design (LEED ) , a national consensus -based standard under the United States Green Building Council (USGBC ) for developing sustainable or high performance buildings , is water efficiency . A LEED registered project can attain up to five points under water efficiency upon successful integration of various techniques to conserve water . Many techniques are available to conserve water and grey water reuse is one option considered by many LEED registered projects . In spite of widespread popularity , some of the sustainable techniques including grey water reuse , which is recommended by the USGBC and various agencies engaged in green building constructions , are not viable in many parts of the United States due to their effects on construction cost and project schedules . Even though a project could get one or multiple points upon successful implementation of a grey water reuse system and conserving potable water , the following factors may have a positive or negative effect on the design team ?s decision to implement a grey water reuse system : capital cost , maintenance cost , LEED credits , local plumbing codes , project schedule , local water conservation issues , complexity of the system , etc . Implementation of a grey water reuse system has a significant effect on the capital cost of a project . The increase in cost may be attributed to dual sanitary and grey water distribution piping which doubles construction piping costs . Disinfection treatment , filtration , overflow protection , grey water storage tanks , etc . also add to the cost of construction . Ninety percent of the projects claim that project schedule is not affected by the implementation of a grey water reuse system in a green building project . The factors which prevent the project team from implementing a grey water reuse system include capital cost , maintenance cost , local plumbing codes , local water conservation issues , complexity of the system , etc . LEED credits and the spirit of sustainability are the factors which have a positive effect on the design team ?s decision to implement a grey water reuse system .
