    WCTNZ® | Rural Secondary Dwelling Wastewater Package (Connected)

    A connected rural secondary dwelling wastewater package for sites where a small dwelling, cabin, sleepout or granny flat uses a Nature Loo™ Alectura Premium toilet-waste pathway and connects to an existing septic system, onsite treatment plant or sewer mains.

    This package is built around the connected pathway: backflush and heavier wastewater remain on an approved wastewater connection, while recoverable greywater is diverted through the GreyFlow™ PS-AG Automatic range for onsite reuse.

    Connected pathway
    Backflush and heavier wastewater discharge to an existing septic tank, onsite treatment plant or sewer mains connection.
    Greywater recovery
    GreyFlow™ PS-AG Automatic range recovers suitable shower, bathroom basin and laundry greywater for a subsurface irrigation / hydration field.

    GreyFlow™ dripper field
    Subsurface field pathway for recovered shower, bathroom basin and laundry greywater, subject to site suitability and land-application design.

    Why these products are grouped

    A higher-spec connected secondary dwelling pathway

    • Adds the missing toilet-waste pathway so this is a full connected secondary dwelling wastewater package.
    • Uses the Nature Loo™ Alectura Premium for the higher-spec toilet pathway.
    • Designed for connected rural projects where the septic, sewer or treatment pathway already exists or can be extended.
    • Lets the project recover greywater onsite while preserving the approved wastewater connection for backflush and heavier wastewater.
    • Explains why the automatic backflush must remain connected to sewer, septic or treatment.
    Site and consent context

    Final suitability remains project-specific

    Connection requirement: Connection options are confirmed against the existing sewer, septic or onsite treatment pathway. The automatic backflush must discharge to an approved wastewater connection, while the recovered greywater is directed to a suitable subsurface land-application field.
    No standard grease trap: A grease trap is not included as standard because kitchen wastewater and backflush are assumed to remain connected to the approved septic, treatment or sewer pathway. Grease management can be added if the site design requires it.

    *

    Please select the primary pedestal (toilet fixture) option you would like to accompany your composting system.

    Note; that the Urine-Diversion (UD) pedestal option is most suitable where there is high use in peek or large family gatherings.

    Note; that with Urine Diversion, it is recommended that the compost mass is kept wet to avoid the pile drying out. Consider getting the hand-held bidet sprayer accessory for facilitating the hydration of compost.

    A hardwearing Nano-Ceramic Non-Stick Coating is applied onto the inner side of the Pedestal (toilet fixture) for maximum cleanliness.

    Note; basic cleaning will still be required.

    Note; non-stick is hydrophobic and repels liquids only.

    Choose additional chambers to increase the capacity of your system or to provide longer composting times where needed.

    *

    Choose the fan voltage to match your power system. (Add additional fan units for replacement parts).

    All ELV (Extra Low Voltage) (12v-48V) are suitable for Off-grid power systems.

    Vent stack kit for installation.

    In residential applications, a vertical vent must extend 0.6m above the roofline - this is a code requirement.

    *

    You may need additional vent materials depending on how many storeys your building has.

    Single Storey buildings with a high-profile roof (A frame or mono-pitch) require extra lengths of vent pipe - add one 800mm Vent Pipe Extension

    Double Storey buildings require extra lengths of vent pipe. Please add 4 x 1m Vent Pipe Extensions.

    Double Storey building with a high-profile roof (A frame or mono-pitch) require extra lengths of vent pipe - add one 800mm Vent Pipe Extension

    Kit for stepping the vent stack around the eaves of the roof. Allows you to avoid penetrating the roof.

    A wind-driven vent offers the best redundancy for your system ventilation. The wind-driven vent will assist the fan under heavy wind conditions, keeping the system operational in the event of a power outage or fan failure.
    SharkVent™ | Wind Ventilator has high efficiency with a linear wind direction windvane (good for storm-prone areas).
    Universal Vent ACC | Wind-Driven Vent has high efficiency in low windage. 2 colours: white or black.

    Select this reducing collar to adapt the vent from 150mm to 100mm.

    Select this reducing collar to adapt the vent from 150mm to 100mm.

    Extend your soft connection leachate drainpipe to reach your hard connection leachate drainpipe or soak-pit/trench.

    Soft connections allow for flexible placement of the composting tank in relation to a hard connection or drain.

    The system is packed with 1 meter of 25mm leachate drainpipe as a standard.

    Extend your leachate drain via in-ground hard connection to reach your soak-pit/trench (soak-away).

    Most soak-aways should be installed 3 meters away from the foundations of the structure but this remains circumstantial to the site.

    Run your leachate drain into a soak pit (vertical soak-away) or into a trench (horizontal soak-away).
