Luxury water engineering for your home & family

Pure water,
by design.

An independent engineering firm designing private water systems for the estates of Los Angeles. Every shower, every bath, every glass.

We operate as a design firm. Every estate is tested, every system is drawn for that house alone, and no two are the same.

What we design against

City water meets federal limits. Those limits leave a great deal unaddressed.

Microplastics

Fragments shed from pipes, packaging and the wider environment.

PFAS

The "forever chemicals." Federal deadlines continue to slip.

Chloramine

The disinfectant Los Angeles uses. Felt on skin and hair.

Lead

Picked up from service lines and older fittings on the way in.

Pharmaceuticals

Trace residues that conventional treatment does not target.

Fluoride

Removed from drinking water for clients who prefer it out.

The system

Treated where it matters.

Water that touches your skin and water you drink are held to different standards, so the system treats them separately.

Whole home

Every surface you touch.

All water entering the house is filtered before it reaches a shower, bath or faucet.

  • 01
    Sediment removes sand and rust from the main.
  • 02
    Catalytic carbon removes chloramine and chemical byproducts.
  • 03
    Ultrafiltration blocks particles down to 0.02 microns, including microplastics.
Showers · Baths · Faucets
Drinking

Every glass you drink.

A dedicated loop takes the filtered water further, then restores the minerals that make it taste right.

  • 04
    Reverse osmosis removes PFAS, lead, fluoride, pharmaceuticals and what is left.
  • 05
    Remineralization adds back calcium and magnesium for taste and balance.
  • 06
    Ultraviolet gives a final polish before the tap.

Toilets, irrigation and pool are left on city water. Equipment is selected per project from established manufacturers. We sell none of it.

Inside the plant room

Below grade. Out of mind.

Drag to turn the room. Tap a marker to see what each stage does.

Plant room
City water enters at left. Filtered water leaves for the house, and a second line continues on to drinking water.
What stays on city water
Toilets, irrigation and pool. The plant treats only what you touch and drink.

Illustrative layout. Every plant room is designed for its house.

Out of sight

You will never see it.
We always will.

The plant is built into the property, below grade, in a service wing or beneath the garage. Sensors report on it around the clock, and anything unusual goes straight to your engineer.

Concealed

Vault, service wing or below slab. Designed with your architect.

Monitored

Quality, pressure, flow and leaks, watched continuously.

Never without water

If anything faults, the house switches to city supply automatically.

Maintained

Filters, membranes and lab testing handled on schedule. You never call a vendor.

Why independent

A water company sells you a system.
We design yours.

The usual route

  • A product line from one manufacturer
  • Sized by a salesperson on commission
  • Softening and carbon, the same at every address
  • A box in the garage

Solenne

  • Vendor independent. No equipment sales, no commission
  • Designed by an environmental engineer from your test results
  • A system drawn for one house
  • Built into the architecture, then looked after
The process

From your first sample to every year after.

01

Test

Certified lab analysis at the meter and at the tap.

02

Report

What is in your water, in plain language.

03

Design

A system drawn for your home and your architect.

04

Build

Licensed trades install it to our specification.

05

Verify

Tested again before we sign off.

06

Maintain

Monitored and serviced for the life of the system.

Begin

Start with a test.

Engagements are limited. Existing homes and new builds are both welcome, and the earlier we join a build, the cleaner the result.
