NSF 350-2017

Onsite residential and commercial water reuse treatment systems

Published by: 2016-08-26 / 2016-08-26 / 56 pages
This Standard contains minimum requirements for onsite residential and commercial water treatment
systems. Systems may include the following.

  • Graywater treatment systems having a rated treatment capacity up to 5,678 L/day (1,500 gal/day).
    This applies to onsite residential and commercial treatment systems that treat graywater, those that
    treat laundry water from residential laundry facilities, and those that treat bathing water. See 8.1 for
    performance testing and evaluation.
  • Commercial treatment systems — this applies to onsite commercial treatment systems that treat
    combined commercial facility wastewater and commercial facility laundry water of any capacity, and
    those treatment systems that treat graywater from commercial facilities with capacities exceeding 5,678
    L/day (1,500 gal/day). These systems shall be performance tested and evaluated at the location of the
    reuse system installation, using the wastewater generated onsite from the facility serving the treatment
    system. See 8.3 for performance testing and evaluation. The key elements of a field evaluatin of a
    commercial treatment system are described in Annex A.

Management methods and end uses appropriate for the treated efflent discharged from onsite residential
and commercial treatment systems meeting Class R (single family residential) or Class C (multi-family and
commercial facilitiesds) requirements of this Standard include indoor restricted urban water use, such as
toilet and urinal flushing, and outdoor unrestricted urban water use, such as surface irrigation. Effluent
quality criteria consistent with these uses are described in 8.6, Criteria.

This Standard is intended to address public health and environmental issues. Actual performance for any
site or system may vary, depending on variations in raw water supply (such as alkalinity and hardness),
wastewater constituents, and patterns of use. The end use of the effluent is the responsibility of the owner,
design professionals, and regulatory officials.

System components covered under other NSF or NSF/ANSI standards or criteria shall also comply with the
requirements therein. This Standard shall in no way restrict new system designs, provided such designs
meet the minimum specifications described herein.

Equipment covered by this Standard includes, but is not limited to, specialty equipment items or devices
that have special, complex, or multiple functions such as refrigeration heating equipment, and refrigerated
tumblers equipment. These are applicable provisions and additional specific requirements or exceptions
as might be needed for proper evaluation of devices or equipment for which individual standards do not
exist.

The requirements of this Standard shall apply to all specialty equipment items except when equipment
components and materials are covered under other NSF or NSF/ANSI Standards or criteria. Components
and materials covered by other NSF or NSF/ANSI Standards or criteria shall comply with the
requirements of each relevant standard or criteria to which that particular equipment component or
material applies. This Standard is not intended to restrict new unit design, provided that such design
meets the minimum specifications described herein.

Ultraviolet Microbiological Water Treatment Systems

Published by: 2016-09-09 / 2016-09-09 / 62 pages
The purpose of this Standard is to establish minimum requirements for the reduction of microorganisms
using ultraviolet radiation (UV). UV water treatment systems covered by this Standard are intended for
water that may be either microbiologically safe or microbiologically unsafe. This Standard also specifies
the minimum product literature and labeling information that a manufacturer shall supply to authorized
representatives and system owners, as well as the minimum service-related obligations that the
manufacturer shall extend to system owners.

Reverse Osmosis Drinking Water Treatment Systems

Published by: 2016-05-23 / 2016-05-23 / 84 pages
The purpose of this Standard is to establish minimum requirements for materials, design and construction,
and performance of reverse osmosis drinking water treatment systems. This Standard also specifies the
minimum product literature that manufacturers shall supply to authorized representatives and owners, as well
as the minimum service-related obligations that manufacturers shall extend to system owners.

The point-of-use reverse osmosis drinking water treatment systems addressed by this Standard are designed
to be used for the reduction of specific substances that may be present in drinking water supplies (public or
private) considered to be microbiologically safe and of known quality (except that claims for the reduction of
filterable cysts may be permitted). Systems covered by this Standard are intended for reduction of total
dissolved solids (TDS) and other contaminants specified herein. Systems with components or functions
covered under other NSF or NSF/ANSI Standards or Criteria shall conform to the applicable requirements
therein

Commercial Cooking, Rethermalization and Powered Hot Food Holding and Transportation Equipment

Published by: 2016-04-14 / 2016-04-14 / 56 pages
Equipment covered by this Standard includes, but is not limited to, ranges, ovens, fat/oil fryers, fat/oil filters, griddles, tilting griddle skillets, broilers, steam and pressure cookers, kettles, rotisseries, toasters, coffee makers and other hot beverage makers, component water heating equipment, proofing boxes and cabinets, hot food holding equipment, rethermalization equipment, and hot food transport cabinets.


Section 7 of this Standard pertains to food handling and processing equipment that has been designed and manufactured for special use purposes. Food equipment designed and manufactured with a security package is utilized in environments such as correctional facilities, mental health facilities, or some schools. For these environments, where both sanitation and security are concerns, 7 contains exceptions to this Standard that shall only be applicable to the splash and non-food zones of food equipment provided with a security package.


Equipment components and materials covered under other NSF or NSF/ANSI Standards or Criteria shall also comply with the requirements therein. This Standard is not intended to restrict new unit design, provided that such design meets the minimum specifications described herein.

Published by: 2016-04-05 / 2016-04-05 / 72 pages
This standard establishes minimum materials, design and construction, and performance requirements for point-of-use and point-of-entry drinking water distillation systems and the components used in these systems. Distillation systems covered by this standard are designed to reduce specific chemical contaminants from potable drinking water supplies. systems covered under this standard may also be designed to reduce microbiological contaminants, including bacteria, viruses, and cysts, from potable drinking water supplies. It is recognized that a system may be effective in controlling one or more of these contaminants, but systems are not required to control all.

Systems covered by this standard are not intended for the treatment of water that is visually contaminated (turbid) or has an obvious contamination source, such as raw sewage, nor are systems covered by this standard intended to convert wastewater to microbiologically potable water.
