STP Instant Price Estimator

Get an indicative, VAT-inclusive starting price for a DENR-compliant sewage treatment plant in seconds. Final pricing follows a site inspection and influent test.

1 · Your Industry

What kind of facility is this for?

2 · Discharge Standard

Which DENR class must your treated water meet? (based on your receiving water body — ask us if unsure)

Class B / SBStricter — bays, beaches, protected waters

Class C / SCMost common — rivers, creeks, reuse

Class D / SDBasic — drainage / agricultural waters

3 · Flow & Build Route

Daily wastewater flow: 10 m³/day

520 m³/day

Not sure? Wastewater ≈ 80% of your water consumption. ~1 m³/day serves roughly 8–12 people or 4–5 hotel rooms.

4 · Optional & Separate Items

I have a kitchen / canteen / food service (needs a grease interceptor — quoted separately)

I want IWSI to build the civil works too (underground concrete tanks with manhole covers — quoted separately after site inspection)

Note on civil works: IWSI can construct underground reinforced-concrete tanks with manhole covers, sized to the volume above. This is priced per project after a site inspection and structural design, so it is not included in the figure above. A primary settler is not part of IWSI's scope.

All fields are required — every detail helps us give you an accurate quote. Attach your sanitary plans, drawings or lab results; whatever is missing we will assume conservatively and confirm after a site visit.

This estimator gives an indicative starting price only, derived from past IWSI projects. It is not a formal offer. Actual pricing depends on site conditions, influent characteristics, available space, existing tanks and the confirmed discharge standard, verified during a site inspection and laboratory analysis. All figures are VAT-inclusive and exclude civil works, permits, grease interceptor and long-distance logistics unless stated.
