Woodland’s water has historically been derived from groundwater wells with water hardness levels that averaged about 18 grains per gallon. For this reason, water softeners have been a popular choice for many Woodland residents over the years. With completion of the Woodland-Davis Clean Water Agency’s Surface Water Treatment Plant in mid-2016, Woodland’s primary water source is now surface water pumped from the Sacramento River.
This water averages about 4 grains per gallon and is considered to be moderately hard. Some Woodland residents have found that lower hardness has allowed them to reduce or even discontinue water softener use.
