Guidelines for Design of Small Public Water Systems (Greenbook)

This publication has been prepared as a guide for professional engineers and water supply specialists engaged in the design or development of small public water systems using only ground water. The objective here is to assure that new or substantially modified public water system facilities such as those for factories, mobile home parks, office buildings, restaurants, condominiums, and the like will be capable of producing an adequate supply of potable water in compliance with applicable regulations.

The purpose of this manual is to present the requirements and procedures necessary to develop an approved water supply system where connection to an existing public water system cannot be made at reasonable cost. This publication includes treatment design criteria for iron, manganese, and hardness removal.
