Introduction
Sustainable development is a mindful and planned effort that combines environmental, social and economic aspects into a development strategy to ensure the integrity of the environment also the safety, abilities, welfare, and quality of life of present and future generations [1]. One of the efforts in realizing sustainable development is by carrying out development on the Drinking Water Field. This study will review the fulfillment of clean water in Central Java Province and the need for implementation of Green WSS at Regional WSS in Central Java (Case Study Of Bregas Water Supply System). Implementation of Green WSS in Regional WSS covers the application of green open space in the all of water plant building, utilization of renewable energy source (green energy), low carbon and the effort of developing energy-saving and green building in water treatment plant, in its planning stage,construction stage and operational stage.
It is expected that with the implementation of Green WSS on Regional WSS development in Central Java can improve drinking water service followed by significant economic development.

Literature Review
Drinking Water Supply System hereinafter abbreviated as WSS is a unity of facilities and infrastructure of drinking water supply.
WSS type consists of WSS pipeline network and WSS not pipeline network. WSS pipeline networks include raw water units, production units, distribution units, and service units, while WSS not a pipeline network consisting of shallow wells, pump wells, rainwater catchment basins, water terminals and water catchment buildings.
The implementation of WSS is held to ensure people's right to drinking water, access to drinking water services and fulfill the daily basic needs of drinking water for the community.
The regional system in the implementation of WSS development refers to the second Master Plan namely the WSS Master Plan Development across Districts and/or Cities. The Master Plan is established by the Governor with the support of the Joint Decree of the respective regional head.
In the case of availability of raw water, the Central Government and the Regional Government shall ensure the availability of raw water. Central Government and Local Government can do cooperation between regions in the framework of raw water utilization efficiency. Green WSS is an important issue in development in Indonesia due to the low level of green WSS implementation on existing water supply building. Basically, the application of Green WSS cannot be separated from green construction which is the basic step of indicator to produce green building.
Green building is a concept for 'sustainable building' and has certain conditions, namely location, planning and design system, renovation and operation, which adheres to the principle of energy saving and must have positive impact for environment, economy and social (Ministry of Environment, 2001). In planning of WSS buildings, green building begins at the planning, development, operation and maintenance operations with pay attention to aspects of protecting, saving, reducing the use of natural resources, maintaining the air quality in the room and pay attention on the occupants health. In this study, Green WSS is a sustainable movement that aspires to create green building from the planning, construction and operational & maintenance phase. In order to realize the movement, an assessment indicator is required in each phasing. Determination of indicators at the planning stage, construction phase, and operational & maintenance stage includes 5 aspects, namely technical aspects, laws and regulations, institutions, social, and finance.

Identification Of Green Water Supply System Indicators
An indicator is a variable that can be used to evaluate the situation or the possibility of measurement of changes occurring over time. An indicator does not always explain the situation as a whole but often gives only a hint or indication of the overall state as an estimate. Indicators must be simple, timely, measurable, useful, and reliable. This analysis will discuss the current condition of Bregas Regional Water Supply System with reference to 3 stages of Green Water Supply System indicator covering technical, legal and regulatory, institutional, , financial and social aspects. Each indicator consists of several ratings containing credit that has a certain value charge and will be processed to determine the final value. In the selection of issues and indicators that will be used has been conducted site survey based on the real situation to obtain the following indicators: From Green Water Supply System indicator above, then will be analyzed by means of assessment of each answer on each substance has been determined, namely: a) score 1-5 if it supports Green WSS (according to rating that have a predetermined value charge) b) score 0 if it does not supports Green WSS Examples: If there has a Feasibility Study (FS) document, then it is stated support Green WSS, then by category: -Complete Feasibility Study, score 5 -Feasibility Study Simple, score 3 -Technical and cost justification, score 1 Based on the considerations, to determine whether a building can be stated to have eco-friendly building criteria, the final result of scoring indicator analysis has a total scoring value of ≥75 of 100% total.
