Incoming water filtration and water tank lining

Why raw supply water stains pools and villas

Many properties in Phuket and across Thailand use borehole water or local deliveries containing dissolved iron and manganese. When untreated water fills or tops up a pool, it reacts with the pool water treatment and leaves brown, yellow or dark stains across the finish, grout and fittings.

• Incoming water filtration for the pool fill and automatic top-up line to reduce metal staining
• Filtering the main water supply into the villa so bathrooms, kitchens and laundry equipment receive treated water from the same plant
• Protecting new PebbleCrete and tiled pool interiors from metal staining right from the first fill

Filtration vessels, water tanks and media servicing

We assemble and install incoming filtration sets matched to your raw water source, and we line concrete water storage tanks.

We can order a test of the incoming water from an approved laboratory we work with. It is the same kind of laboratory condominiums use for their regular water reports. We then design the filtration system from the results.

• Filtration equipment with automatic backwash controls, selected for sediment and metal content in the incoming water
• Waterproofing and lining concrete domestic water tanks and balance tanks
• Periodic servicing of the filtration plant, including valve checks, backwash settings and replacing exhausted filter media when due
• Checking raw water quality, existing storage tanks, booster pumps and pipe runs before specifying the setup

Draining, water supply and how work is organised

Most filtration work takes place in the pump room or beside the storage tanks. An on-site inspection decides whether a tank or pool must be drained, and the programme is agreed for the individual project.

• Incoming filtration installation: inspection confirms water supply interruptions and pool use arrangements
• Tank or pool must be drained: lining a concrete water storage tank or balance tank requires emptying that tank, and renovating a heavily stained pool shell requires draining the pool. Draining an in-ground pool or underground tank in the wet season or with high groundwater needs care, and hidden substrate or waterproofing problems may only show once work starts, so work can go in stages
• Who decides what: we inspect your raw water, tank condition and plant space, then agree with you whether to filter the pool fill line alone or the whole property

What to send for a first discussion

Send us a few details so we can review your water setup before our visit.

• Photos of your existing water tanks, incoming supply pipes, pump room and any staining in the pool
• The property location, approximate pool size and whether water comes from a borehole, mains supply or truck delivery
• Any water test results you already have
• What you want changed, such as pool fill filtration, whole-house filtration, tank lining or filter media servicing
