    WCTNZ® | Rural Secondary Dwelling Wastewater Package

    A rural secondary dwelling wastewater package for minor dwellings, sleepouts, farm accommodation and small secondary buildings where a Nature Loo™ Alectura Comfort toilet-waste pathway and GreyFlow™ PS-AG Manual greywater diversion can work together.

    The package combines the Alectura Comfort composting toilet pathway with the GreyFlow™ PS-AG Manual range and a subsurface dripper field pathway, without assuming an automatic backflush connection.

    Build the package from the products below

    This rural secondary dwelling wastewater package is designed for minor dwellings, sleepouts, farm accommodation and small secondary buildings where a compact composting toilet system and manual GreyFlow™ greywater diversion can work together.

    This is a situation-based grouped package rather than a fixed discount bundle. Select the required products and options below so the final package matches the site, use level and installation pathway.
    System pathway

    What this package is designed to cover

    Toilet-waste pathway
    Nature Loo™ Alectura Comfort composting toilet system for the toilet-waste pathway in a rural secondary dwelling, sleepout, farm accommodation or minor dwelling.
    Greywater diversion
    GreyFlow™ PS-AG Manual range for pumped greywater diversion where the site needs more capability than a small compact greywater unit.
    Land application
    GreyFlow™ dripper field pathway for suitable shower, bathroom basin and laundry greywater, subject to site levels, soil conditions and available land-application area.
    Grease management
    Grease trap is not included as standard. Passway™ grease separation can be added where kitchen wastewater enters the selected greywater pathway or where the site design requires kitchen-line protection.
    Package components

    Recommended core products to select below

    Nature Loo™ Alectura Comfort
    Compact composting toilet system for the toilet-waste pathway, suited to smaller secondary dwelling and compact building projects where the selected model rating and installation requirements are met.
    GreyFlow™ PS-AG Manual range
    Select PS-AG-M1, PS-AG-M3 or PS-AG-M4 according to flow, pumping head, terrain and rural secondary dwelling requirements.
    GreyFlow™ dripper field
    Subsurface land-application pathway for diverted greywater where soil conditions, site levels and available land area are suitable.
    Optional grease management
    Passway™ grease separation can be added if kitchen wastewater joins the greywater pathway or if the wastewater design requires additional kitchen protection.
    No automatic backflush requirement
    This package uses the manual PS-AG range and does not rely on an automatic backflush discharge connection.
    Why these products are grouped

    A practical starting point for a rural secondary dwelling

    • Adds the toilet-waste pathway so this is a full secondary dwelling wastewater package, not just a greywater package.
    • Uses the Nature Loo™ Alectura Comfort for the toilet-waste pathway.
    • Uses the GreyFlow™ PS-AG Manual range for a stronger pumped greywater pathway without requiring automatic backflush.
    • Allows grease management to be added only where kitchen wastewater joins the greywater pathway or the site design requires it.
    • Supports a practical council review pathway for rural secondary dwelling projects.
    Site and consent context

    Final suitability remains project-specific

    Manual greywater pathway: This package uses the GreyFlow™ PS-AG Manual range, so it does not require an automatic backflush discharge connection. Final model selection depends on user load, greywater source, pumping head, terrain and the proposed subsurface land-application field.
    NZ Building Code and council review: WCTNZ® can provide product information, technical documentation and consent-support information for customers, designers, builders, plumbers and wastewater professionals reviewing a rural secondary dwelling wastewater pathway.

    *

    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.

    Add a wind-driven vent to create redundancy. 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.
    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).

    For all Dripper Feilds, you require flush valves for yearly maintenance.

    Add this kit if you have downhill runs where the slope (gradient) exceeds 3°.

    Note: this kit is for a standard 100 linear metre dripper field with 7 x 14 linear metre dripper runs.

    If you have more than 7 runs, add one additional flow restrictor per run.

    Note: you will need 1 less flow restrictor in total than your total amount of runs, as the last run is non-restricted.
