This document specifies general safety and performance requirements for design and testing as well as sustainability considerations for non-sewered sanitation systems (NSSS). A NSSS, for the purposes of this document, is a prefabricated integrated treatment unit, comprising frontend (toilet facility) and backend (treatment facility) components that a) collects, conveys, and fully treats the specific input within the system, to allow for safe reuse or disposal of the generated solid, liquid, and gaseous output, and b) is not connected to a networked sewer or networked drainage systems. This document is applicable to sanitation systems that are either manufactured as one package, or manufactured as a set of prefabricated elements designed to be assembled in one location without further fabrication or modification that influences the system function. The plane or surface (e.g. flooring, concrete pad) upon which a fully assembled NSSS is situated is beyond the scope of this document. This document is not applicable to sanitation systems constructed in situ. This document also covers NSSS backend components that are designed to be integrated with one or more specified frontends. Although this document is primarily applicable to the development of sanitation systems that are not connected to water and electricity networks, it can also be applied to systems that can utilize water mains and/or electricity. This document defines the basic treatable input as primarily human excreta and gives options for extending the range of input substances. Requirements for the quality of the outputs from the sanitation system are given for solid and liquid discharges as well as odour, air, and noise emissions. It contains criteria for the safety, functionality, usability, reliability, and maintainability of the system, as well as its compatibility with environmental protection goals. This document does not encompass the following aspects: — guidelines for selection, installation, operation and maintenance, and management of sanitation systems; — transportation of treated output outside of the sanitation system (e.g. manual transport, transportation by truck or trunk pipes) for further processing, reuse, or disposal; — treatment processes taking place at another location separate from that of the frontend and backend components; — reuse and disposal of sanitation system output.

Chemical dispensing systems provide a means of mixing potable water with chemicals to provide the user with a chemical solution which is ready for use. The amount of dilution shall be fixed or adjustable. Devices covered by this standard are intended for stationary installations, mobile devices where the orientations are fixed, and hand-held devices. This standard applies to those devices classified as chemical dispensing systems and shall be protected by an air gap complying to ASME A112.1.3-2000 (R2015), an integral elastomer gap, or an Atmospheric Vacuum Breaker (AVB). If an AVB is used as its method of backflow protection, it must conform with ASSE 1001 or CSA B64.1.1.

1 Scope

1.1 General

1.1.1 This standard covers devices for detection, monitoring or control of water supply and distribution systems in sizes DN 8 to DN 300 (NPS‐1/4 to NPS‐12) for commercial and residential applications and specifies requirements for materials, performance testing, environmental limitations, installation, and markings.

1.1.2 Devices for detection, monitoring or control of plumbing systems, hereinafter referred to as “devices”, covered by this standard govern plumbing systems through features such as:

  • (a) Automatic shut‐off or electronic alarm notification or isolation of the supply piping when conditions are detected indicating a leak or equipment malfunction (e.g. automatic water leak detection and control device).
  • (b) Detecting the presence of water external to the piping system.
  • (c) Establishing normal water flow patterns and monitoring for anomalies.
  • (d) Monitoring of the hydraulic conditions (e.g. water pressure, temperature, or flow) within the main or branch circuit.
  • (e) Monitoring of the local environment that may indicate potential for freeze conditions; or
  • (f) Monitoring of the local environment for moisture that may indicate a leak (e.g. Physical Water/Moisture Detection Devices).
  • (g) Monitoring of environmental conditions.
  • (h) Ongoing analysis of sensor readings or system conditions to ensure monitoring of system integrity.
  • (i) Pressure based or other means of micro leak testing for detection of pinhole leaks or dripping fixtures; or
  • (j) Provide hardwired or remote access to control a valve (e.g. remotely controlled valves).

Note: Several common terms are used to identify devices covered under this standard a few examples of such terms are Water Leak Detection Device, Automatic Water Leak Detection Device, Leak Detection and Control Device, Adaptive Plumbing System Monitoring and Control Device, and Electronic Plumbing Supply System Integrity and Protection Device.
