American Disabilities Act (ADA) Guidlines

Pure Water Technology designed its state-of-the-art 3water purification system to be in compliance with the Americans with Disabilities Act (ADA) as well as the ADA Accessibility Guidelines. Among other things, the Americans with Disabilities Act (ADA) ensures access to the built environment for people with disabilities.  The ADA Standards establish design requirements for the construction and alteration of facilities subject to the law.  These enforceable standards apply to places of public accommodation, commercial facilities, and state and local government facilities.  The United States Access Board is responsible for developing and updating design guidelines known as the ADA Accessibility Guidelines (ADAAG).  These guidelines are used by the Department of Justice (DOJ) and the Department of Transportation (DOT) in setting enforceable standards that the public must follow.  Both DOJ’s and DOT’s current ADA Standards are based on the Board’s updated ADAAG (2004)

Below is a guide which references the applicable standards and guidelines explaining how the 3i is in compliance with these standards. This guide also provides information on clearance and accessibility which will be dependent on the installation location and other environmental factors.

Here are the basics:

  1. The spout height is 36” from the ground, the 3i is 36”.
  2. Maximum height reach is 48”. The 3i user interface is below the 48” guidelines.
  3. Single hand use with force needed under 5 lbs, the 3i can be operated with 1 hand and the pressure required is much less than 5 lbs.

*Some of the provisions in ADA standards are specific to water fountains. The 3i water purification system is not a water fountain (which is designed to allow users to access a stream of water with their mouths) and as such, those standards are not listed.


602 Drinking Fountains 

602.1 General. Drinking fountains shall comply with 307 and 602.

602.2 Clear Floor Space. Units shall have a clear floor or ground space complying with 305 positioned for a forward approach and centered on the unit. Knee and toe clearance complying with 306 shall be provided.

602.4 Spout Height. Spout outlets shall be 36 inches (915 mm) maximum above the finish floor or ground. The spout height of the 3i is 36”.

602.5 Spout Location. The spout shall be located 15 inches (380 mm) minimum from the vertical support and 5 inches (125 mm) maximum from the front edge of the unit, including bumpers.

309 Operable Parts

309.1 General. Operable parts shall comply with 309.

309.2 Clear Floor Space. A clear floor or ground space complying with 305 shall be provided.

309.3 Height. Operable parts shall be placed within one or more of the reach ranges specified in 308.

309.4 Operation. Operable parts shall be operable with one hand and shall not require tight grasping, pinching, or twisting of the wrist. The force required to activate operable parts shall be 5 pounds (22.2 N) maximum. The 3i can be used with one hand with a force of much less than 5 pounds.

308.2 Forward Reach.

308.2.1 Unobstructed. Where a forward reach is unobstructed, the high forward reach shall be 48 inches (1220 mm) maximum and the low forward reach shall be 15 inches (380 mm) minimum above the finish floor or ground. The user interface for the 3i (hot and cold buttons) are under 48”.


Location and Environment Standards

The following guidelines are the responsibility of the customer and not the installing dealer. Please be sure the area you select for installation allows for the clearances below.

305.1 General. Clear floor or ground space shall comply with 305.

305.2 Floor or Ground Surfaces. Floor or ground surfaces of a clear floor or ground space shall comply with 302. Changes in level are not permitted.

   EXCEPTION: Slopes not steeper than 1:48 shall be permitted.

305.3 Size. The clear floor or ground space shall be 30 inches (760 mm) minimum by 48 inches (1220 mm) minimum.

305.4 Knee and Toe Clearance. Unless otherwise specified, clear floor or ground space shall be permitted to include knee and toe clearance complying with 306.

305.5 Position. Unless otherwise specified, clear floor or ground space shall be positioned for either forward or parallel approach to an element.

Position of Clear Floor or Ground Space

305.6 Approach. One full unobstructed side of the clear floor or ground space shall adjoin an accessible route or adjoin another clear floor or ground space.

305.7 Maneuvering Clearance. Where a clear floor or ground space is located in an alcove or otherwise confined on all or part of three sides, additional maneuvering clearance shall be provided in accordance with 305.7.1 and 305.7.2.

305.7.1 Forward Approach. Alcoves shall be 36 inches (915 mm)wide minimum where the depth exceeds 24 inches (610 mm).
