Well Water Filtration & Treatment

Well Water Filtration & Treatment in Daly City

Treatment for private wells and springs on coastal and hillside properties around the north Peninsula.

Private water deserves a proper plan

Well water filtration and treatment around Daly City applies to the minority of properties on private wells or springs, mostly on larger coastal and hillside parcels south toward Pacifica and beyond. Those owners treat their own water, and it can carry iron, manganese, sediment, hardness or bacteria.

Order matters. Sediment comes out first, then iron and manganese, then hardness, and disinfection last, so each stage protects the next. We test the water fully, design the system around your results and your pump, and add sample ports so every stage can be checked.

Every system comes with a written record of the test, the stages and the settings.

Coastal conditions

Near the coast, salt air is hard on exposed metal. We keep equipment indoors where possible and use corrosion-resistant fittings for anything outside.

Coastal wells can also be affected by heavy winter rain. An annual test, and another after any unusual weather or well work, keeps you ahead of changes.

Many of the wells we see on the coastside were drilled decades ago, and the records are often missing. We start by finding out what we can about the well's depth, the pump and the pressure tank, because a system that suits a shallow well with a small pump is different from one built for a deep, high-yield well. The plan then follows the test results, stage by stage, with nothing added for the sake of it.

What a system can include

Built from your test results.

  • Full panel

    Bacteria, iron, manganese, hardness, pH, TDS and turbidity.

  • Sediment screen

    Stops sand first.

  • Iron removal

    Air injection or oxidizing media.

  • pH correction

    Protects copper pipes.

  • Softening

    Only if hardness is present.

  • UV disinfection

    Final stage.

  • Sample ports

    Check each stage.

  • Pump review

    Flow sets the sizing.

How the project goes

  1. We test

    Samples at the pressure tank; results explained within about a week.

  2. We design

    Stage-by-stage plan with one price.

  3. We install

    Usually most of a day, then sanitization and a confirming test.

Questions people ask

How often should I test?

At least once a year, and after heavy rain or well work.

Why are my fixtures stained?

Usually iron or manganese, which we can remove.

Buying a property with a well?

Test before closing.

How often should a well be tested?

At least once a year for bacteria, and again after heavy rain, flooding or any work on the well or pump.

Can you work with my existing equipment?

Often, yes. We test it first and keep anything that is still doing its job.
