Get a Sewage Treatment Plant
Need a sewage treatment plant? Start with the price.
Most people asking about an STP want one number before anything else: what does it cost. Our estimator gives you an indicative, VAT-inclusive figure in about thirty seconds — no call, no waiting for someone to get back to you. Then, if it makes sense, we design it properly.
Who Needs One
You probably need an STP if
- Your building permit, occupancy permit or business permit is conditional on having a wastewater treatment facility.
- You are building a hotel, condominium, hospital, commercial building, school or factory.
- DENR, your LGU, your water utility, your mall admin or your industrial park has asked for a discharge permit.
- You have a septic tank only, and the water leaving it goes to a canal, creek or drainage line.
- Your existing plant has stopped meeting its limits and you are deciding whether to fix or replace it.
What It Costs
Why nobody can quote you over the phone
The honest answer is that flow rate alone does not set the price. A 20 m³/day plant for an office building and a 20 m³/day plant for a hospital are different machines, because the strength of the wastewater and the parameters you are held to are different. Whether you already have usable tanks changes the figure more than almost anything else.
So instead of asking you to wait for a callback, we built the estimator. Pick your facility type, your discharge class and your flow, and it returns an indicative starting price based on prices we have actually charged on comparable projects — not a textbook figure.
Your Options
Three ways to build it
Retrofit what you have
Where existing septic or treatment tanks have usable volume and sound structure, we install the treatment inside them. Usually the cheapest route, and the fastest, because there is no excavation.
Brand-new fibreglass
Modular prefabricated tanks, set above ground or semi-inground. Fast to install, minimal site disruption — suited to sites with space and to projects on a schedule.
New concrete, built by us
Reinforced concrete tanks with manhole covers and a covered pump and blower room, for underground and basement installations. Quoted separately from the treatment system so you can see both numbers.
What You Get
Included as standard
A design built around your site
Process flow, tank schedule with real dimensions, equipment list and scope of works — not a catalogue page with your name on it.
Compliance on every parameter
Where domestic sewage is involved that means ammonia, nitrate, phosphate, surfactants and coliform — not just BOD and solids.
A sludge plan
Every design includes how sludge is digested, wasted and removed. Plants that ignore sludge fail eventually.
Commissioning and proof
Biological start-up, operator orientation and accredited third-party effluent testing, so you have documentation for your permit.
Support afterwards
Maintenance, consumables, probiotics and troubleshooting from the same team that built it.
Reuse, if it pays
Tertiary polishing so treated water can flush toilets and irrigate landscaping. On high-water-bill facilities this often pays for itself.

Flow rate, available space and where the treated water will go — that is enough for us to start.
