NOTE 2 The minimum level of performance (hydraulic efficiency and structural behaviour) are given by the test carried out on one model of the range. 3.5 site assembled domestic wastewater treatment plant unit composed of prefabricated components assembled on one site by one manufacturer, which accepts domestic wastewater and treats it to a declared quality 3.6 extension shaft component(s) which, when placed on the top of the plant, allow access from or slightly above the ground surface
NOTE 1 It permits accessibility and maintenance work.
NOTE 2 It may be either a vertical extension piece of the tank, or components, which are fitted only over certain points for example to allow maintenance or observation.
