Wastewater Treatment Design Generator
Engineered process design, matched to your industry
Select your industry and download a design brief built from treatment plants Innovative Water Solutions has already designed and delivered in the Philippines — process flow, retention times, working volumes and equipment. Every design is set to the Class B / SB compliance envelope.
1 · Choose your industry
The design brief is matched to your sector’s significant effluent parameters under DAO 2016-08 Table 8. Enter your design flow and operating hours and the brief will size every stage by hydraulic retention time.

What is in the brief
Basis of design
Your PSIC classification, the significant parameters DENR monitors for your sector, and the discharge basis.
Influent design basis
The wastewater strength the plant is engineered against — flow pattern, organic load, nutrients, solids.
Target effluent quality
The Class B / SB envelope, parameter by parameter, with the process step that delivers each one.
Process flow diagram
The full liquid treatment line and the sludge line, drawn as a labelled process flow.
Retention time and volumes
Hydraulic retention time for every stage, and the indicative working volume each one needs at your flow.
Equipment list
Every major item in the plant, described by function and duty.
Water reuse
Where the treated water can be put back to work on your site, and what has to be checked first.
How these designs are built
Every brief on this page comes from a treatment plant IWSI has already engineered — not from a catalogue.
Compliance first
Each design carries the full nutrient, disinfection and polishing train needed to hold the Class B / SB envelope, which is stricter than the Class C basis most Philippine inland sites are permitted against. A design that clears B / SB clears C.
Sized, not guessed
Retention times come from delivered IWSI plants and scale with wastewater strength — a fish market carries far longer aeration than an office tower, and a plant running one shift a day needs a far larger equalisation stage.
Reuse built in
Filtration, carbon and a second disinfection barrier are carried in every train, so the treated water is fit for toilet flushing, irrigation and washdown rather than only fit to discharge.
Serviceable by design
Continuous-flow fixed-film biology, fewer critical moving parts, straightforward troubleshooting and a practical sludge plan. Built to run reliably after turnover.
Design briefs are preliminary and issued for planning purposes. Retention times and working volumes are indicative and are confirmed against actual influent laboratory analysis, site survey and the approved civil design. Final effluent design must be confirmed against the applicable DENR EMB Region, LLDA, water utility, LGU or site-specific discharge requirement before implementation.
