Laundry-to-Landscape vs. Branched-Drain Greywater Cost Guide
The two simple greywater tiers price two different purchases. A laundry-to-landscape system draws on one clothes washer and prices at $800 to $2,000 in the Modernize frame, at the low end of the Angi frame. A branched-drain system draws on showers, tubs, and bathroom sinks and prices inside the whole-system bands. This guide prices the two tiers apart, frame by frame, including the permit split between them.

The two simple tiers, priced side by side
| Simple tier | Angi 2026 band | Modernize 2026 band |
|---|---|---|
| Laundry-to-landscape | low end $600; inside normal range | basic, no-tank $800-$2,000 |
| Branched-drain | inside normal range $2,200-$5,500 | inside average range $2,500-$4,500 |
The ordering is consistent and the bands never merge. Laundry-to-landscape is the lower-priced tier in both frames, and the only tier with its own published line in the Modernize frame, the basic no-tank band at $800 to $2,000. Neither frame publishes a separate branched-drain line, so a branched-drain quote arrives inside the whole-system bands, the Angi normal range of $2,200 to $5,500 or the Modernize average range of $2,500 to $4,500, and should name its tier. The full tier table, including pumped and treated systems, sits on the greywater system cost hub.
What each tier price carries
The two prices buy different scopes, priced as different purchases. The laundry-to-landscape price carries a single source, the clothes washer, and no tank in the Modernize frame's basic band. The branched-drain price carries several sources, showers, tubs, and bathroom sinks, which is where its higher band comes from: the Modernize frame names system complexity and number of water sources first among its cost factors, and the Angi frame names system type and daily capacity. Neither scope statement is a procedure; both are the published basis for the price difference.
The permit split between the two tiers, as reported context
The reported California code tiers put a permit line between these two purchases, as reported code context only. Published summaries of Chapter 15 report the clothes-washer tier as permit-exempt when all reported conditions are met, and the simple-system tier, the tier a branched-drain system falls into, as permit-required. Where a permit applies, the Angi frame prices permit fees at $50 to $1,000, a line that belongs to the branched-drain side of this comparison. Local ordinances and notification requirements are reported to still apply to both tiers. The permit decision itself prices on the greywater permit and code cost guide.
Gravity and plumbing access, as reported cost lines only
Two drivers recur across the published reporting, each a reported cost line only. Gravity fall: both simple tiers are priced as gravity systems in the reporting, and a site reported as lacking fall toward the landscape prices the distribution side higher. Plumbing access: the Modernize frame names the existing plumbing layout among its cost factors, and a layout reported as difficult to reach prices above one reported as open. The same frame names local labor rates and add-ons such as tanks, and the Angi frame names site preparation as a cost line priced apart. Each is a reported reason a quote lands high or low inside its band.
How this guide differs from the hub and the permit guide
The greywater system cost hub prices the whole purchase: every tier, both frames, and the permit and maintenance lines together. This guide prices only the decision between the two simple tiers. The greywater permit and code cost guide prices the permit decision across all reported tiers; this guide carries the permit split only where it separates these two tiers, as one cost line in the comparison.

Frequently asked questions
How much does a laundry-to-landscape system cost compared with a branched-drain system?
In the Modernize frame, basic laundry-to-landscape prices at $800 to $2,000 on its own published line. Branched-drain has no separate line in either frame and prices inside the whole-system bands: the Angi normal range of $2,200 to $5,500 or the Modernize average range of $2,500 to $4,500.
Why does a branched-drain system price above laundry-to-landscape?
The published reporting prices different scopes: one source and no tank on the laundry-to-landscape side, several sources on the branched-drain side. The Modernize frame names system complexity and number of water sources first among its cost factors.
Which of the two tiers is reported to need a permit?
As reported code context only: published summaries of Chapter 15 report the clothes-washer tier as permit-exempt when all reported conditions are met, and the simple-system tier, which covers branched-drain, as permit-required. Where a permit applies, Angi permit fees run $50 to $1,000.
What moves a quote inside its band on either tier?
The reported cost lines are gravity fall, the existing plumbing layout and its access, local labor rates, site preparation in the Angi frame, and add-ons such as tanks in the Modernize frame.
Is branched-drain the same purchase as a pumped or treated system?
No. Branched-drain is a gravity tier priced inside the whole-system bands. Pumped and treated systems price on their own lines, to the $20,000 high end in both frames, on the greywater system cost hub.
