What we do
Everything your pool needs, from one team
Maintenance keeps water safe and clean; repairs keep everything behind it running. We handle both — no subcontracting, no waiting on a third party.
Pump room maintenance
Regular servicing of filtration plants, chemical dosing systems and pump room equipment, so problems are caught before they surface in the water.
Pump & motor repair
Diagnosis and repair of circulation pumps and motors, with replacement recommendations only when a repair no longer makes economic sense.
Valve replacement
Worn multiport and check valves replaced cleanly, restoring proper flow and backwash function without disrupting your pool schedule.
Tiling works
Cracked, hollow or missing pool tiles repaired and re-laid — even underwater — keeping the pool safe underfoot and looking the way it was designed to.
Lighting & electrical
Underwater light replacement and electrical troubleshooting, handled safely by technicians who work around water every day.
Why Hydrology
Chosen by the people accountable for pools
Managing agents and MCSTs answer to residents. We make sure the pool is never the complaint.
Proven at scale
Over 200 pools maintained island-wide, including condominium and government projects where standards are audited, not assumed.
One team, one number
You deal directly with the people doing the work. Call 8299 2702 and you reach us — not a call centre.
Maintenance plus repair
Because we service and repair, small faults get fixed during the weekly visit instead of growing into downtime.
How it works
From first visit to a pool you never worry about
Site visit & assessment
We inspect your pool, pump room and water condition, and listen to what's been going wrong.
A plan and a price
You get a clear maintenance proposal — scope, schedule and cost — within one working day.
Scheduled weekly care
The same team services your pool every week: cleaning, balancing, and equipment checks.
Repairs, handled
When something wears out, we repair it in-house — pumps, valves, tiles, lights — without a second contractor.
