Case Summary (G.R. No. 202897)

Procedural Background and Claims

DENR-EMB regional offices charged MWSS, Maynilad, and Manila Water before the PAB for failure to install and maintain adequate wastewater treatment facilities (WWTFs) and to connect existing sewage lines, leading to pollution of waterways draining into Manila Bay. The DENR Secretary, acting on the PAB’s findings, imposed daily fines for Section 8 violations. Petitioners’ motions for reconsideration were denied. They then filed Rule 43 petitions in the Court of Appeals, raising due-process and jurisdictional objections, claiming Section 7 conditions and Concession Agreement milestones justified delay, and citing this Court’s MMDA Manila Bay decision.

Legislative Framework and Policy of the Clean Water Act

RA 9275 unifies water pollution control under a “holistic” national program.

  • Section 7: DPWH, with DENR, LGUs, and other agencies, must prepare a National Sewerage and Septage Management Program within 12 months of effectivity.
  • Section 8: Within five years of effectivity (by May 6, 2009), MWSS and its concessionaires in Metro Manila and other HUCs must connect all existing sewage lines (from apartments, hotels, hospitals, households, etc.) to available sewerage systems; rates may be charged unless a source has its own system.
  • Section 28: Authorizes the DENR Secretary, upon PAB recommendation, to impose P10,000–P200,000 daily fines for violations, with a 10% biennial escalation, and to order closures or disconnect water supply.

Administrative Proceedings and Findings of DENR-PAB

After a Notice of Violation and technical conference, the PAB found petitioners in continuing violation of Section 8, noting incomplete centralized sewerage and evidence of untreated discharge. It recommended maximum fines. The DENR Secretary adopted those findings in Orders of October 7 and December 2, 2009, imposing P200,000 daily fines from May 7 to September 30, 2009, and P200,000 per day thereafter until compliance.

Court of Appeals Rulings

Each CA division dismissed the Rule 43 petitions:

  • Maynilad (CA-G.R. SP 113374): Dismissed for procedural default—late reconsideration.
  • Manila Water (CA-G.R. SP 112023): Held Section 8’s five-year deadline clear and separate from Section 7 and NSSMP formulation.
  • MWSS (CA-G.R. SP 112041): Ruled the wrong remedy was sought and failure to exhaust administrative appeals; substantively confirmed its concessionaires’ duties under Section 8.

Issues before the Supreme Court

Procedural

  1. Validity and appealability of DENR Secretary’s Orders under RA 9275 and EO 192.
  2. Alleged denial of procedural due process.

Substantive

  1. Petitioners’ compliance with Section 8:
    1.1. Is Section 7 a condition precedent?
    1.2. Do Concession Agreements override Section 8?
    1.3. Any exemption from the five-year deadline?
  2. Effect of MMDA Manila Bay decision on Section 8’s deadline.
  3. Proper computation of fines under Section 28.

Procedural Determinations

  • The daily-fine Orders were issued by the DENR Secretary, pursuant to Section 28, and are appealable to the Office of the President, not by Rule 43 to the CA.
  • Petitioners failed to exhaust administrative remedies, warranting dismissal on technical grounds.
  • Due process was afforded: Notice of Violation, PAB technical conference, written submissions, and motions for reconsideration.

Substantive Determinations: Scope of Section 8

  • Section 8 imposes an unconditional duty, demandable by May 6, 2009, irrespective of Section 7 or NSSMP completion.
  • Section 7’s 12-month IRR program is distinct, not a condition precedent.
  • Concession Agreements expressly require compliance with Philippine laws and cannot modify statutory deadlines.
  • MOAs extending concession terms to 2037 cannot override the five-year statutory mandate.

Public Trust Doctrine and State’s Regulatory Role

Under the 1987 Constitution, water is a natural resource held in public trust. MWSS and its concessionaires function as fiduciaries, tasked with protecting water quality and sanitation. RA 9275 is a valid exercise of the State’s police power in furtherance of public welfare, health, and environmental protection.

Violation of Section 8 by Petitioners

DENR-EMB laboratory analyses and monitoring confirmed widespread pollution from untreated sewage. By 2017, petitioners’ sewerage coverage ranged from 9–19%, far sh
