PROTOCOL FOR INSTALLERS

    1. Waterflow NZ Ltd generates enquiry through marketing and advertising. The client details are then passed onto the Installer to arrange a site visit for site evaluation and quote. (This maybe supported by Waterflow under a ‘Bronze’ level arrangement) Leads will be also loaded onto the Installers Smartsheet page which the Installer is to keep updated in a timely fashion as each process/step is completed.
    2. Contact of ‘leads’ supplied by Waterflow New Zealand Limited to be made within 24hrs of Installer receiving the lead information. All leads supplied by Waterflow New Zealand limited are required to be sold Waterflow products unless by written consent from Waterflow New Zealand Ltd.
    3. Site evaluations require the following detail to be completed and communicated to Waterflow NZ Ltd to advise on the best solution for the site, where necessary. Site Visit to be completed within 5 working days of receiving the enquiry unless client prefers a later date.‐ Site Investigation Form – complete all details (Appendix A)‐ Slope Assessment – (Appendix B)

      Soil Profile Images – Dig or auger a min 2 soil profiles per disposal area @ 1.2m deep, and take a minimum of 4 photos of the soil laid out in order of log – as per attached sample (Appendix C)

      Assessment of Soil Texture (Appendix D)

      Site Images ‐ 2-3 of the wastewater system and disposal field area (Appendix E)

      Site plan ‐ showing location of the dwelling, wastewater system and disposal field (Appendix F)

    4. Waterflow NZ Ltd can assist with pricing for systems and materials as delivered to site. A quote is then provided to the client for the system and installation.This process needs to be completed within 2 days of site visit.
    5. Once the proposal has been accepted, Waterflow NZ Ltd can then provide Wastewater Design Report for Council consent on all PA sites, which can take up to 10 working days. Waterflow will need confirmed site & floor plans and a recent Certificate of Title to Waterflow will require a $1000 + GST deposit on the System before releasing the   Wastewater Report for consenting.      
    6. All NaturalFlow Systems and disposal fields are to be installed as per approved design and installation specifications ‐ Installations Images of System serial numbers, all fittings and joins, gravel used for backfilling and disposal field layout are required for sign off. Qty approx. 8‐10. These images must be sent to Waterflow NZ Ltd to assess correct installation and provide PS4.
    7. At time of commissioning the following details are required. This process is completed once the system is connected and there is running water. A copy of all the documents need to be supplied to Waterflow NZ Ltd.‐ Commissioning Checklist – supplied by Waterflow NZ Ltd (Appendix G)

      Service Contract between the Installer and the client to be signed – supplied by Waterflow NZ Ltd (Appendix H)

      As Built Plan (PS3) of system and disposal field to be sent to Waterflow NZ Ltd and client (Appendix I)

      Construction Review (PS4) photos of installation to be supplied to designer.

      Note: in order to have a PS4 supplied we need clear install photos as per shown in Appendix G and clear as built showing system and field type and positioning off fixed points on site.

      Waterflow is not obliged to make payment for the installation until the job is complete, including the all final documentation.

    9. Customer relationships and Company integrity to be always maintained at the highest level.

Slope Assessment
1.11 Conversion of per cent grade, slope, and gradient

This Standard refers to slopes as the ‘per cent grade’. Table 1.1 provides conversions for typical ‘per cent grade’ into the equivalent ‘slope angle’ and ‘slope ratio’, with each defined as:

  1. Per cent grade or grade (%) is the ratio of the vertical distance to the horizontal distance converted into per cent, (with 100% being a one to one ratio of equal horizontal and vertical distances, also equivalent to 45 degrees);
  2. Slope angle or degrees (°) is the arctan of the vertical distance divided by the horizontal distance (that is tan of the slope angle is the vertical distance divided by the horizontal distance); and
  3. Slope ratio (V:H) is the horizontal distance (H) that equates to a 1 m change in the vertical distance (V).

Assessment of Soil Textures
Soil Category Classification Properties
1 Sand Very little to no coherence; cannot be molded; single grains stick to fingers
2 Loamy Sand Slight coherence; forms a fragile cast that just bears handling; gives a very short (5mm) ribbon that breaks easily: discolors the fingers
Sandy Loam Forms a cast but will not roll into a coherent ball; individual sand grains can be seen and felt; gives a ribbon 15-25mm long
3 Fine Sandy Loam As for sandy loams, except that individual sand grains are not visible, although they can be heard and felt; gives a ribbon 15- 25mm long
Loam As for sandy loams but cast feels spongy, with no obvious sandiness or silkiness; may feel greasy if much organic matter is present; forms a thick ribbon about 25mm long
Silty Loam As for loams but not spongy; very smooth and silky; will form a very thin ribbon 25mm long and dries out rapidly
4 Sandy Clay Loam Can be rolled into a ball in which sand grains can be felt; forms a ribbon 25 – 40mm long
Clay Loam Can be rolled into a ball with a rather spongy feel; slightly plastic; smooth to manipulate; will form a ribbon 40 – 50mm long
Silty Clay Loam As for clay loams but not spongy; very smooth and silky; will form a ribbon about 40 – 50mm long; dries rapidly
5 Sandy Clay Forms a plastic ball in which sand grains can be seen, felt or heard; forms a ribbon 50-75mm long
Light Clay Smooth plastic ball that can be rolled into a rod; slight resistance to shearing between thumb & forefinger; forms a ribbon 50 – 75mm long
Silty Clay As for light clay but very smooth and silky; will form a ribbon about 50 – 75mm long but very fragmentary; dries out rapidly
6 Medium Clay Smooth plastic ball, handles like plasticine and can be molded into rods without fracture; some resistance to ribboning, forms a ribbon 75mm or more in length
Heavy Clay Smooth plastic ball that handles like stiff plasticine; can be molded into rods with fracture; firm resistance to ribboning; forms a ribbon 75mm or more in length
Site Images

Depending on the layout onsite, it is sometimes easier to get the system and field in the same image, rather than the house and system as shown in examples below.

Also try to get a more overall image to help us understand how things are in relation to each other.

House location and System location in first image
Disposal Field location image
Site Layout Plan

A site plan should show the house field and system location, as well as flowpaths, ponds, boundaries and other design constraints.

Naturalflow Installation Requirements

Take plenty of pictures as you install the system. Remember we aren’t there, so any future questions will be answered from the photos you take.

Prepped hole with fines for bedding & leveling
Perfect hole with minimal space around the tanks
Straight connection, Ensure connection into end of a Wormorator® foot, not side.
Tank connections, the configuration will vary depending how the tanks are positioned.
Whenever possible use a draincoil to take groundwater away from the installated tanks. Minimum depth for the draincoil is the bottom of the Wormorator®. Where a draincoil cannot be used, cement must be added to the backfill metal.
Backfill chip should come to the top of the tanks. Do not backfill with soil.

Naturalflow System Commissioning Checklist

Naturalflow System Service Contract

Disposal Field installation - LPED

LPED irrigation is low pressure, so will not work up and down contour, please ensure the lines are laid level around the contour.

Lateral lengths and spacing along with the orifice hole size and spacings are shown on the layout plan provided with each job. The lines should be pinned to the ground approx every 1.5m

Each LPED line should be laid along the contour.
When surfacing laying the irrigation, the flush valves should be marked with short stakes.
Disposal Field installation - Cut off Drain

On some sloping sites a cut off drain will be specified. This is to divert surface water away from the irrigation area.

Cut off drain above irrigation area.
