Performance-Based Sanitation Engineering

Just because something meets the rules doesn’t mean it’s doing its best to keep us healthy.
And what really keeps us safe is how well it performs.

⸻

For years, sanitation projects have been judged mainly on:
• design approval,
• construction completion,
• commissioning results.

Once a plant is ready and declared “compliant,” it’s easy to forget about it—until something goes wrong, overflows, or doesn’t pass inspection.

This approach assumes that just getting the standards right once is enough.

But it’s not.

⸻

Sanitation engineering needs to move from focusing on just meeting the rules to really focusing on how well it works.

Meeting the rules answers the question:

“Does this meet the minimum standards today?”

But performance answers the tougher questions:
• Does the system run smoothly every day?
• Can it handle unexpected events, weather changes, and staff changes?
• Are the costs for energy, chemicals, and maintenance manageable?
• Can we track and prove how well it’s working?

A system that’s compliant but unreliable is still a problem.

True success in sanitation engineering is measured over many years, not just when it’s first built.

⸻

Commitment / Direction (Vision for PSSE)

As part of PSSE leadership, I think the profession should start to see:
• performance indicators, not just design requirements
• thinking about long-term operation when designing
• being responsible even after the project is finished.

Engineering gets more respect when we’re judged by what we achieve, not just what we plan.

Performance-based thinking is how sanitation engineering builds trust—with regulators, communities, and decision-makers.

⸻

If you’re designing systems, ask yourself how they’ll perform after a year.
If you’re reviewing projects, ask how you’ll measure their performance.
If you’re running facilities, keep a record of what’s actually working.

Performance isn’t extra work.
It’s the real work.

🌿 World Wetlands Day — February 2

Wetlands are not “idle land.” They are natural infrastructure. They store floodwaters, filter pollution, recharge groundwater, protect coastlines, and support fisheries and biodiversity. When wetlands are destroyed, floods worsen, water quality collapses, and disaster costs explode. You either protect wetlands now—or pay for engineered fixes forever.

In the Philippines, wetlands are frontline defenses against flooding and storm surge, especially in coastal and low-lying cities. Sites like Las Piñas–Parañaque Wetland Park, Agusan Marsh Wildlife Sanctuary, and Olango Island Wildlife Sanctuary prove one thing: protect wetlands, and communities become more resilient. Reclaim or pollute them, and floods, water contamination, and ecological loss follow—guaranteed.

• Protect: Oppose reclamation and encroachment on wetlands.
• Reduce pollution: Practice proper waste segregation; stop dumping into waterways.
• Restore: Support mangrove and wetland rehabilitation programs.
• Participate: Join wetland cleanups, awareness events, or local conservation drives.
• Demand better planning: Push LGUs to treat wetlands as flood-control and water-quality assets, not vacant land.

Wetlands save lives, water, and money. Ignore them—and nature sends the bill.

Congratulations to the January 2026 Sanitary Engineering Licensure Examination passers.

Passing the board exam is not the finish line.
It is the point where accountability begins.

As a Sanitary Engineer since 2019, a member of the Philippine Society of Sanitary Engineers Inc., and someone who has spent the last 6 years designing, building, and operating real water and wastewater treatment systems — I’ll say this plainly:

The license gives you authority.
Your decisions will determine whether communities are protected or put at risk.

In practice, no one will ask for your rating.
They will ask if your system works, if your numbers are defensible, and if you are willing to stand by your design when budgets, timelines, and pressure push people toward shortcuts.

Welcome to the profession.
Protect public health. Respect the science. And never forget that sanitary engineering is a public trust.

To the new engineers: keep learning on site — theory earns the license, judgment earns respect.

Digitalization isn’t just the future of sanitation engineering; it’s the foundation.

If sanitation engineering still depends solely on drawings, logbooks, and site visits, we’re already falling behind.

⸻

Across the Philippines, we’re still designing and building sanitation systems using mostly analog methods:
• manual operation logs
• periodic grab sampling
• reactive maintenance
• performance checks only during inspections or crises

Meanwhile, other industries are moving forward—using real-time data, predictive maintenance, and performance dashboards to manage complex systems on a large scale.

Sanitation engineering can’t afford to lag behind. The consequences are too severe: public health, environmental protection, regulatory compliance, and the long-term sustainability of our systems.

⸻

Digitalization in sanitation engineering is often misunderstood.

It’s not about adding more sensors.
It’s not about fancy dashboards.
It’s not about replacing engineers with software.

Digitalization is about making system performance clear, measurable, and accountable.

When sanitation systems are digitalized correctly, engineers can:
• spot problems before they cause failures
• tell design flaws apart from operational issues
• get a true picture of O&M costs over time
• support operators with data, not just guesses
• back up technical decisions with facts, not just opinions

More importantly, digitalization changes the profession from:

“Did we build it?”
to
“Is it working as planned, consistently, and sustainably?”

That change is where engineering credibility is rebuilt.

⸻

Commitment / Direction (Vision for PSSE)

As part of the leadership of the Philippine Society of Sanitary Engineers, my perspective is straightforward:

Digitalization needs to be a core skill, not just something we add on.

This means that over the next few years, PSSE should focus on:
• integrating digital monitoring and data interpretation into professional training
• encouraging a focus on performance, not just meeting regulations
• promoting standards that support long-term monitoring and transparency
• preparing engineers to work alongside operators, regulators, and decision-makers using shared data

Digital tools should strengthen engineering judgment—not replace it.

If sanitary engineers do not lead this transition, others will define it for us.

⸻

For practicing engineers:
Start asking not just how a system is designed, but how its performance will be tracked after turnover.

For younger engineers:
Learn to read data, not just drawings.

And for the profession as a whole:
Digitalization is not about technology.
It is about responsibility.

That is the direction sanitation engineering must take.

Skills Gap in Water/Wastewater Engineers (Philippines) — Industry Reality Check

The water and wastewater industry isn’t suffering from a lack of engineers.

It’s suffering from a lack of engineers who can deliver systems that actually work in real life.

⸻

We have thousands of licensed engineers in the Philippines, and yet we still see the same pattern repeating across projects:
• treatment plants that look good on paper but fail after turnover
• systems that pass commissioning but collapse in operation
• operators left with equipment they don’t understand
• LGUs spending millions — then quietly accepting substandard performance because “at least may facility”

And it’s not always because people are incompetent.
It’s because the profession has a structural gap between what is taught, what is designed, and what is actually needed in the field.

⸻

The skills gap is not mostly about computation.
Most engineers can compute BOD loading, flowrates, sludge age, tank volumes, and pump head.

The real gap is in systems thinking, which includes five things that determine whether a facility survives 5–10 years:

1) Engineers know CAPEX, but ignore OPEX
A lot of designs optimize for project approval, not long-term operation.

In reality, the plant dies because:
• power cost is too high
• chemicals are too expensive
• maintenance parts aren’t available locally
• sludge hauling was never planned
• monitoring requirements were underestimated

A “cheap build” becomes an expensive failure.

2) Engineers design for compliance—not for reliability
Compliance is a target. Reliability is a capability.

Many plants are “compliant” only when:
• influent is stable
• weather is good
• operators are highly skilled
• equipment is new
• management is watching

Real plants must perform when:
• inflow spikes
• toxic shocks happen
• rains dilute or flood systems
• blowers fail
• operators change
• budget is delayed

That’s the real world.

3) Many engineers don’t understand operations
This is the harsh truth:
Some engineers have never operated a plant they designed.

So they don’t design for:
• simple troubleshooting
• operator-friendly controls
• realistic maintenance intervals
• easy access for cleaning and repairs
• clear SOP-based operation

If operators can’t sustain it daily, the design is already dead.

4) Engineers don’t speak “procurement and contracts”
Projects don’t fail only in the technical stage.
They fail in bidding and implementation because technical intent gets destroyed by:
• lowest-bid procurement
• generic specs copied from old templates
• vague performance requirements
• no penalties for underperformance
• no incentives for long-term uptime

You can design the best system in the world—
but if the contract is weak, the outcome is weak.

5) Engineers lack performance accountability culture
We rarely publish:
• uptime
• O&M cost per cubic meter
• energy per kg BOD removed
• non-compliance incidents
• corrective maintenance logs

Without performance transparency, we keep repeating mistakes.
And the profession stays stuck in “project completion” mindset, instead of system performance mindset.

———

As National Director of the Philippine Society of Sanitary Engineers, and as CEO/CTO of Ariescor Water, my direction is clear:

We must shift the profession from being design-focused to being outcome-focused.

That means pushing for:
• stronger real-world training for young engineers
• performance-based thinking (not just compliance thinking)
• deeper involvement of engineers in procurement and governance
• systems designed for Filipino realities: budget limits, power cost, operator constraints, and long-term maintenance

In 2026 and beyond, the profession must produce engineers who can deliver treatment plants that survive—not just plants that get built.

⸻

If you’re a young water or sanitary engineer, here’s my challenge:

Don’t just aim to become someone who can calculate designs.
Aim to become someone who can make systems work.

And if you’re already practicing—ask yourself honestly:
Have you ever stayed long enough to see your system perform after turnover?

Because that’s where real engineering begins.

Why compliance does not equal safety in waste infrastructure

———

One of the most dangerous myths in infrastructure is this:

“We are compliant, therefore we are safe.”

Compliance is a minimum standard.
Safety is a continuous condition.

In waste infrastructure, especially sanitary landfills, systems rarely fail because standards were unknown.
They fail because standards were treated as checklists, not limits.

Here’s the uncomfortable truth:
• A landfill can be fully compliant on paper
• While operating beyond its original design assumptions
• With risks that have quietly shifted over time

Compliance does not account for:
• Accumulated loading beyond design life
• Operational shortcuts normalized by urgency
• Drainage and slope conditions altered by years of modification
• Human decisions layered on top of technical systems

Regulations are static.
Landfills are not.

When engineers stop asking “Is this still safe?”
and only ask “Are we still compliant?”
failure becomes a matter of when, not if.

The most critical risks in waste facilities live between audits —
not inside them.

If the incident in Cebu City teaches us anything, it is this:

Infrastructure does not fail because rules were absent.
It fails because judgment was replaced by comfort.

Safety is not a certificate.
It is a discipline.

17/01/2026

Three early warning signs every sanitary landfill engineer knows — and why they are often ignored

⸻

Every sanitary landfill failure is preceded by warning signs.
Not weeks before — years before.

Here are three that engineers recognize immediately — and institutions routinely ignore:

1. “Temporary” overloading becomes permanent
Design limits are exceeded with the excuse of urgency.
Emergency capacity quietly becomes normal operating condition.
No recalculation. No redesign. Just hope.

2. Leachate behavior starts changing
Unexpected seepage points.
Altered flow paths.
Increased pore pressure within waste slopes.
These are not minor issues — they are structural messages.

3. Operations drift away from design intent
What was engineered on paper is no longer what exists on site.
Compaction practices change.
Drainage gets compromised.
Monitoring becomes reactive instead of predictive.

None of these are invisible.
They are seen.
They are discussed.
And then they are rationalized.

Because stopping operations is inconvenient.
Because redesign costs money.
Because enforcement creates friction.

Until physics enforces itself.

The most dangerous phrase in infrastructure is not “failure.”
It is “we’ve been operating like this for years.”

If this incident teaches us anything, it’s this:
Disasters don’t come from ignorance.
They come from normalized risk.

♻️ National Zero Waste Month — January (Philippines)

Zero waste is not a slogan—it’s an engineering and governance problem. Every kilo of waste we fail to reduce or recover ends up in landfills, waterways, or the food chain. Waste reduction and sustainable consumption protect public health, cut LGU hauling costs, extend landfill life, and reduce climate impact from methane emissions.

In the Philippines, most cities still struggle with segregation at source, weak MRF performance, and landfill dependency—despite Republic Act No. 9003 being in place for over two decades. Zero Waste Month is a reminder that compliance alone is not enough; systems must actually work—from households to barangays to disposal facilities. Poor waste management today becomes tomorrow’s flooding, landfill failure, and water contamination.

• Reduce: Buy less, choose reusable, reject single-use plastics.
• Segregate: Biodegradable, recyclable, residual—no shortcuts.
• Recover: Compost food waste; support functional barangay MRFs.
• Act locally: Join or organize a community cleanup or waste audit.
• Demand better systems: Hold LGUs accountable for real zero-waste infrastructure—not just posters and slogans.

Zero waste starts at home—but it only succeeds when engineering, policy, and discipline meet.

14/01/2026

The sanitary landfill incident in Cebu City is not an accident.

It is a systems failure.

Sanitary landfills don’t collapse because of “bad luck.”
They fail when engineering limits are ignored, operational creep becomes normal, and compliance is treated as paperwork instead of physics.

This is what usually happens:
• Design limits are exceeded “temporarily”
• Waste stacking grows faster than controls
• Drainage, slope stability, and load management are compromised
• Warning signs are seen — and rationalized away

Until gravity collects the debt.

This is not about blame.
This is about accountability.

If we only respond after people are hurt, then we are not managing waste — we are managing consequences.

Engineering is not about reacting to failure.
It is about preventing failure long before it becomes visible.

This incident should force every LGU, regulator, and engineer to ask one uncomfortable question:

What risks are we normalizing today that will fail tomorrow?
