Utility Master Plans
The City's Master Plan Process was completed in July 2016 and evaluated the existing water distribution system and wastewater collection system for the City of Greenfield. The Master Planning process, conducted by the Wallace Group, investigated existing and potential future deficiencies for both systems and recommend improvements to insure the City has adequate facilities to support future growth as defined in the current adopted City General Plan, as well as other additionally anticipated development.
Water Master Plan
The 2021 master plan for the City's water system (PDF) examined existing water distribution system, including facilities, conditions, processes, and hydraulic requirements for existing water sources (water supply wells). It also inspected reservoirs/storage tanks, booster pump stations, pressure zones, and distribution/transmission pipelines.
The plan also documented capital improvements and system expansions completed over the past 10-20 years; existing water flows and projected future requirements for water demand based on historical water consumption and population, land use and economic growth projections, quantify water demand requirements, and determined required pipe sizes and well pumping capacity to transport peak demand flows through the system.
The completed plan developed projections of water distribution demand for a 10 year and 20 year planning horizon by utilizing present and future flow information to determine the quantity and required pipe sizes to transport flows through the system within appropriate pressure levels to all areas within the system. The plan also identified current water reservoir storage requirements for operational (peak demand), emergency, and fire storage and identified required capital and system improvements and expansions to meet future needs.
The 2021 wastewater master plan (PDF) evaluated the existing sewer collection system to determine areas of deficiency including proper design flows and cavitation at lift stations and documented existing wastewater flows and projections of future requirements based on historical wastewater consumption and population, land use and economic growth projections, quantified sanitary flow and wastewater demand requirements.

Wastewater Treatment Facility Master Plan
The 2021 wastewater master plan (PDF) evaluated the existing sewer collection system to determine areas of deficiency including proper design flows and cavitation at lift stations and documented existing wastewater flows and projections of future requirements based on historical wastewater consumption and population, land use and economic growth projections, quantified sanitary flow and wastewater demand requirements. This information was used to determine the quantity and required pipe sizes to transport flows through the system without excessive surcharge or overflow; current collection system and wastewater treatment plant capacities and required capital and system improvements and expansions to meet future needs. The completed plan identified needed and recommended improvements to collection pipeline system, lift stations, SCADA, and wastewater treatment plant and the estimated construction costs for each capital improvement project along with timeline for design and construction of required capital improvement projects.
