The Amana Water Department utilizes groundwater sources for most of their water. Water is typically pumped to treatment facilities if needed, and then to pressure tanks or towers located at high points throughout the Colonies. The height of our water towers are relative to the distribution area – along with the weight of the water – is what generates pressure. The higher the tank, the greater the pressure.

The pressurized water moves from the tank or tower to the water mains that feed the community. Depending on the circumstances of the area, booster stations may be located throughout, which use pumps to maintain pressure. In areas where pressure becomes too high, pressure reducing stations transfer high-pressure water to low-pressure areas, maintaining manageable levels throughout the system.

Residential water pressure tends to range between 45 and 80 psi (pounds per square inch). Anything below 40 psi is considered low and the minimum pressure required by the Iowa DNR is 20 psi. Pressures above 80 psi are too high.

Whereas low water pressure is more of a nuisance than a serious problem (some fixtures, like washing machines, dishwashers, water softeners, have minimum pressure requirements), high water pressure increases the risk of damage to pipes, joints, fixtures, and seals – not to mention increased water waste.
