- Chamber inside-dimensions auto-derive: length = max(0.90 m, 3 × valve_dia + 0.30) gives 0.95 m for 100 mm valve, 1.20 m for 300 mm; width = max(0.75 m, valve_dia + 0.60). Override only if site has constraints — defaults match CPHEEO Manual Chapter 9 + JJM tech-spec.
- Walls 230 mm thick are adequate for chambers ≤ 1.5 m deep. For deeper chambers under heavy traffic load, bump to 345 mm (1½-brick) — switch via the dropdown.
- RCC cover slab is 125 mm with 8 mm bars @ 150 mm c/c bothways (≈ 100 kg/m³). For chambers under H-class traffic load (highway carriageway), use 150 mm slab + 110 kg/m³ — adjust manually.
- Sluice valve rate sourced from MJP SSR 2023-24 p172 item d (PN-1.6 with bypass). For PN-1.0 (low pressure), reduce ~20 %; for PN-2.5 (very high pressure), add ~30 %.
- BOQ shows valve rate based on selected diameter: 50 mm → BW.SLUICE.50 (₹6,988), 150 mm → DI.SLUICE.VL (₹42,000 all-in incl. chamber estimate — when using this you double-count the chamber; manual subtraction needed if you want pure-valve cost), 300 mm → BW.SLUICE.300 (₹54,774). For 80/100/200/250 mm — interpolate from MJP SSR p172 table d items i-ix.
- Excludes: thrust block on either side of valve flange (cast 0.2-0.5 m³ M20 RCC on each side — add via DSR 5.3 manually); painting of chamber exterior (paint 15.x ~₹100/m²); access road / approach paving; CI surround / cast-iron rim if the chamber is in a paved carriageway.
A **Sluice Valve Chamber (SVC)** is the brick-masonry pit that houses a sluice valve on a water-supply main, providing access for operation + maintenance + replacement without excavating the buried pipe. **Standard JJM practice** places SVCs every 500 m on transmission mains and at every off-take on distribution networks — a typical 10-km transmission line has 20+ chambers. Per **IS 2065 + CPHEEO Manual Chapter 9** the chamber is sized to give 300 mm clearance around the valve body, has a PCC bed, brick walls in CM 1:6 (230 or 345 mm thick), internal cement plaster, and an RCC cover slab with CI manhole frame + cover. This Builder generates the per-chamber BOQ — multiply by number of chambers across your scheme.
Why every transmission main needs SVCs every 500 m
Sluice valves serve three purposes on a transmission main: **(1) Isolation** — close a section for repair / replacement without shutting the whole pipeline; (2) **Flow control** — partially throttle flow to balance branches; (3) **De-watering** — drain a section before opening for inspection. Without SVCs, a single pipe burst would mean shutting the entire main + losing service to all downstream consumers for 6-24 hours. With SVCs every 500 m, isolation affects only that segment + downstream — restoration is in hours, not days. CPHEEO Manual mandates SVCs at every change of direction > 11° (alongside thrust blocks), at every off-take, and every 500 m on long mains. For distribution networks JJM spec mandates SVCs at every road crossing + every hamlet boundary.
Chamber dimension rules of thumb
**Inside length** = valve face-to-face dimension + 300 mm clearance on each side for spanner / chain wrench access. For 150 mm sluice valve (face-to-face ~330 mm per IS 2065), inside L ≈ 0.95 m. **Inside width** = valve outer diameter + 600 mm clearance for shoulder room. For 150 mm valve, inside W ≈ 0.85 m. **Inside depth** = pipe invert depth below ground + valve height + 300 mm above-spindle clearance. For 1.2 m pipe cover and 150 mm valve, inside H ≈ 1.5 m. **Wall thickness**: 230 mm (full brick) suffices for chambers ≤ 1.5 m deep without traffic load. Increase to 345 mm (1.5-brick) if deeper than 1.5 m OR under regular vehicular load. **Cover slab**: 125 mm RCC M20 with 8 mm bars @ 150 mm c/c bothways for non-traffic; 150 mm + 12 mm bars for H-class traffic load.
