Pick Your Spot FirstMeasure the full area of your finished feature before anything else. This drives every number downstream.
Size Your Basin RightYour basin needs to hold enough water to keep the pump running — too small and the pump runs dry.
Measure CarefullyYour length and width go directly into the WIT calculator in Step 2, so get them right up front.
Plan for Rocks EarlyRocks look great but can tear your liner. Think about underlayment before you start digging.

Calculate Your Size

Two quick calculations — first find your Water in Transit, then figure out your basin dimensions.

Step 2a — Water in Transit (WIT)

WIT = the total water moving through your system at any one time. Your basin must hold this much water (plus extra).

L × W × 0.25 × 7.48 = Your WIT in gallons

Heads up: This doesn't include pooling areas. Measure those separately and add them to your basin as a one-time fill.

Step 2b — Basin Size

Your basin needs to hold at least 1.5× your WIT. We recommend 2.5× if you're using MatrixBlox.

What is Geotextile Underlayment?

Underlayment rolls
  • Rocks look great but can poke through your liner over time. Underlayment sits between the two.
  • Soft or shifting soil can create voids under your liner and cause it to stretch and fail.
  • It keeps the soil stable so no air pockets form under the liner.
  • Less wear from rocks and roots means your liner lasts much longer.

Consider MatrixBlox

Most of our kits include these. They hold a lot of water in a small space and keep your pump from running dry.

MatrixBlox

Why MatrixBlox?

These blocks have 96% void space — meaning they hold a huge amount of water while taking up very little room. You can stack gravel, pavers, or landscaping right on top of them.

They snap together quickly with no tools. And because they hold so much water, your pump stays submerged and won't overheat.

Enter your WIT and we'll tell you how many blocks you need.

Compare: Regular gravel only holds about 30% water by volume. MatrixBlox holds 96% — that's more than 3× as much water in the same space.

Compare Brands

We carry several brands with similar kits at different price points. Here's how to shop smart.

How to Shop Smart

Every kit includes a pump, basin, liner, and spillway — but they differ in pump flow rate, liner type, basin size, and price. Here's what to watch for:

Match the Pump to Your SpillwayA good rule: 100 GPH per inch of spillway width. 12" spillway = at least 1,200 GPH.
Check What’s IncludedTake a moment to review exactly what comes with the kit you’re considering—components can vary, so it’s important to know what’s included before making your decision.
️ Know Which Liner You're GettingBudget kits usually come with 20-Mil PVC. Mid-range and premium kits use 45-Mil EPDM.
Does It Include MatrixBlox?Most of our kits do. Double check before comparing a kit that uses plain gravel fill instead.
