Rural Water NZ — Rural Black PE100 HDPE pressure pipe price list
The penstock material $/m for the micro-hydro D26 distance-cost term (RT_286)
Rural Water NZ retail price list for PE100 HDPE pressure pipe (AS/NZS 4130, 12.5 bar) — the pipe grade used for a micro-hydro penstock. Verified via curl+grep of the live page. Single-vendor NZ retail list price (indicative; prices change).
Summary
NZ retail price list for Rural Black PE100 high-density polyethylene pressure pipe (AS/NZS 4130, 12.5 bar / PN12.5), the standard grade for a micro-hydro penstock. Supplies the penstock material cost per metre — the hydro-unique part of the D26 distance-linear CapEx term (the earthworks/trench that dominate the distance cost are anchored separately on the wiki’s existing NZ line-cost data, CR_037 / CR_027).
Key claims
- claim: "PE100 HDPE pressure pipe (Rural Black, AS/NZS 4130, 12.5 Bar) NZ retail list prices (EXCLUDING GST): 50 mm — $403/50 m roll, $754/100 m, $1,365/200 m; 63 mm — $559/50 m, $1,079/100 m, $1,950/200 m. Per metre EXCL GST: 50 mm $8.06 → $6.83 (longer coils cheaper); 63 mm $11.18 → $9.75. Incl GST (×1.15): 50 mm ~$7.85–9.27/m; 63 mm ~$11.21–12.86/m."

Supplies the penstock material component of the micro-hydro D26 distance-cost term (stream_distance × $/m; RT_286): **~8–13/m incl GST**, diameter-dependent (larger flow → larger pipe → higher /m). Pipe diameter is set by the flow/head-loss (velocity ~2.5–3.5 m/s), so treat it as diameter-dependent, not a single constant.
This is the minor part of the distance term. The dominant component is the earthworks/trench (~80–140/m)**, anchored on the wiki's existing NZ line costs ([[cr_037_nz-rural-grid-connection-costs|CR_037]] EA 35/m OH / 140/m UG; [[cr_027_nz-microgrid-reticulation-cost-2026|CR_027]] reticulation ~80/m OH / ~300/m UG, incl trenching) — so the full penstock distance term ≈ **~90–150/m, medium (trench-dominated). See micro_hydro for the build-up. The LV power cable is excluded from the hydro distance term (it is reticulation — CR_027 — and would double-count). Note the engine’s current interim $40/m ([cost.py] D26) is low (≈ pipe-only, omitting earthworks).

- None new.
Research gaps
- A firm NZ earthworks/trenching rate card (Rawlinsons NZ Construction Handbook, or an EDB/council schedule-of-rates) to lift the dominant trench component from corpus-anchored/blog-corroborated to a published unit rate — raised as a follow-on RT.
Notes
Web price list captured direct via curl (ruralwater.co.nz), no AI-retrieval provenance; the roll prices (403/754/1365; 559/1079/1950) and standard (AS/NZS 4130, 12.5 Bar, PE100) were grep-confirmed in the raw HTML. Prices EXCL GST on the page. data_quality high (verified current price to a national standard), but a single-vendor list price — treat the $/m as indicative.
