The Problem

What Happens When
Water Systems Fail

01
Low Pressure. No Water.
You arrive after months away. The pump won't prime. Pressure is nonexistent. Your guests are waiting. This doesn't happen by accident, it happens when systems are installed without design.
02
Constant Pump Failures
Replacing pumps every 12–18 months is not normal maintenance, it's a symptom of a system that was never properly designed for your property's real demand, elevation, and water source.
03
Contaminated Water
Iron, sediment, bacteria, and hardness destroy equipment and make water unsafe. Without the right filtration at the right stage of the system, every other investment is wasted.
04
Contractors Without Accountability
Most water system problems in Caribe Sur trace back to someone who installed without engineering the system first. When things fail, they're gone. We're not, we stand behind every system we design.

There's a better standard.
It starts with design.

What We Do

Complete Water
System Solutions

We don't just install equipment. We diagnose your property's specific water challenges and engineer a complete, layered system designed to perform reliably for years, without you having to think about it.

Water System Design
Full property diagnosis, flow rate, elevation mapping, TDH calculation, water quality analysis, before a single component is specified. The foundation of every system we build.
Pump Installation & Repair
Submersible and surface pump systems selected and sized for your actual application, including well depth, pipe runs, friction losses, and real demand. Done right the first time.
Water Filtration Systems
Custom multi-stage filtration designed for Caribe Sur water conditions: sediment removal, iron filtration, bacteria elimination, UV disinfection, softening, matched to your specific water source and usage.
Pressure & Storage Systems
Pressure tank sizing, accumulator systems, and storage tank design to ensure consistent pressure and water availability, critical for properties with fluctuating supply or seasonal demand.
Complete Property Water Audits
For second-home owners buying or renovating in Caribe Sur, a full technical assessment of your property's water infrastructure with an honest report on what works, what doesn't, and what to prioritize.
System Maintenance & Support
Preventive maintenance programs for property owners who aren't on-site year-round. Remote-friendly reporting, trusted local presence, and rapid response when something needs attention.
Our Standard
WE DON'T INSTALL
SYSTEMS.
WE DESIGN
RELIABILITY.

Most contractors in Caribe Sur will sell you a pump and walk away. Mar & Selva Soluciones engineers the complete water system for your property before a single pipe is placed. That distinction is why our systems last, and why our clients stop worrying about water.

Design Before Installation
Every project starts with a property diagnosis. We calculate real TDH, flow requirements, and water quality before recommending any equipment.
Specialists in Caribe Sur
We know this territory's water conditions, elevation profiles, and infrastructure limitations. Generalist contractors don't. That local knowledge prevents costly mistakes.
Built for Remote Owners
Your property should work when you're not there. We design systems with remote-owner realities in mind, minimal failure points, easy access, and a trusted team you can call from anywhere.
Full Accountability
We document every system we install. If something doesn't perform as designed, we come back. No excuses, no disappearing act.
How It Works

From First Call
to Silent Reliability

01
Property Diagnosis
We assess your water source, pressure, quality, and infrastructure. You get an honest picture of what you're working with before any commitment.
02
System Design
We engineer a complete solution spec'd for your property, pump sizing, filtration stages, pipe layout, pressure management. Nothing generic.
03
Professional Installation
Installed to spec, with correct component placement, proper priming, and full testing before handover. Documented from start to finish.
04
Ongoing Support
We stay available. Preventive maintenance options, remote check-ins, and rapid response, because a reliable system needs a reliable team behind it.
Where We Work

Caribe Sur,
Our Territory

We serve the Caribbean South coast of Costa Rica, the stretch of coastline and jungle foothills where second-home ownership has grown fastest, and where reliable water infrastructure is most often the overlooked variable in a property investment.

Water problems don't announce themselves, they wait until you have guests arriving, a rental booked, or a family vacation planned. The only protection is a system designed to prevent them before they happen.

Who We Are

A Family Business.
A Local Name.

Mar & Selva Soluciones is a family business built on two things: decades of local expertise and a genuine commitment to our clients.

My father Wilberth moved our family to Cahuita over 43 years ago. He has spent nearly 28 of those years working in water pump systems across Caribe Sur, solving problems, learning the land, and building a reputation based entirely on results. When you have been doing this work in the same territory for that long, there is not much you have not seen.

I spent 30 years in corporate environments focused on customer service and sales. That experience gave me a clear understanding of what clients actually need beyond the technical work: honest communication, reliable follow through, and someone who treats their property as seriously as they do.

Last year we decided to combine both skill sets and build Mar & Selva Soluciones together. Our focus is the expat and second home owner community in Caribe Sur, people who have invested in a property here and deserve a water system, and a service team, they can genuinely count on.

The trust our clients have placed in us has grown beyond water systems. They now call us for other property needs across Caribe Sur, and we show up for those too. That confidence means everything to us and we do not take it for granted.

Caribe Sur is our home. Your property is our priority.

"When we found Mar & Selva, I was skeptical, we had already paid several people over many months and none had been able to solve our problems. From the moment we began talking, I found Melvin to be honest and transparent, attentive to understanding the entire scenario before beginning to design a solution. Melvin did not hesitate to put in extra effort, even when it required reviewing issues outside the original agreement. We are absolutely thrilled with the work. We recommend them 200%."

"Melvin and his team came out and re-did my pipes, tanks, and pump. They cleaned the tanks, laid new pipes, and installed a new pump, in about 2 days. I have had nothing but issues with my water system since buying our property, and it's been really great NOT having to worry about it anymore!"

"I called them at the last moment as soon as my tenants told me there was no water. They said they could be there in forty minutes, they were there in fifteen. They inspected and had it up and running in minimal time. They are now my go-to specialists."
