Class B Effluent Limits for Laguna de Bay Shoreline Zone
| Parameter | Class B Limit | Health & Environmental Impact |
|---|---|---|

DENR DAO 2021-19 Wastewater Compliance & Fine Calculator
Estimate your commercial facility's daily wastewater generation (CMD), identify regulatory violation gaps, and preview required STP sizing.
Standard septic systems fail DAO 2021-19 limits by up to 800% for BOD and Coliform. Discharging without biological treatment risks mandatory cease-and-desist orders.
NatureCare Mobile Containerized STP-30
Pre-engineered containerized MBBR system. Installs above-ground with zero major excavation, designed specifically for rapid DAO 2021-19 compliance retrofits.
