Phase I-A grants the developer approval of his well sites and permission to obtain the well drilling permits from the appropriate town to proceed with groundwater exploration and development of such wells. The issuance of this approval means that the Department of Public Utility Control and the Department of Health Services have determined that a main extension to an existing system is not feasible (for new water systems only) and that there will be no duplication of service of other existing water utilities in the area when the project is finished. Phase I-B evaluates the well yield and water quality data so that proper pump sizing, storage and appurtenant equipment and any required treatment processes can be incorporated into the design of the water system. This approval permits the developer to obtain building permits from the town to clear the site, lay out the roads, construct the drainage facilities and dig or pour the foundations of the buildings themselves. Phase II Approval, the final Certificate, permits the developer to go forward with the remainder of the project, i.e. installing the water distribution system and waterworks (storage tanks, transfer pumps, meters, etc.) and the septic or sewer systems (assuming appropriate approvals have already been obtained from the Department of Health Services or local Directors of Health or Department of Environmental Protection) for the septic or sewer systems and the diversion of water.
