A 6-inch catch basin collects surface water and routes it into an underground drainage pipe. For a single-pipe layout, the NDS 101 is a practical choice; the NDS 201 suits a setup that needs two outlets. A basic catch basin kit may suit buyers seeking a basin and grate together, while the Tempo option is listed as a one-outlet basin with limited feature details. The NDS 40 is a grate cover, not a complete basin, and is best considered as a replacement or compatible accessory.

NDS 101 Round Spee-D Catch Basin
The NDS 101 is a 6-inch round plastic basin with one outlet. It is designed to collect stormwater from lawns, landscaped areas, and locations under downspouts, then direct it into a drain pipe. The listed connections include 3-inch and 4-inch sewer and drain, single-wall corrugated, and triple-wall pipes, plus 4-inch DWV/Sch. 40 pipe.
Best for: A homeowner planning one downstream pipe connection who needs a compact collection point for light to moderate runoff. It can also work upstream of a 6-inch pop-up drainage emitter. Limitation: It has one outlet, so it is not the listed option for a layout that requires two basin outlets.
NDS 201 Round Spee-D Basin
The NDS 201 is a 6-inch round basin with two outlets. Like the NDS 101, it collects stormwater from lawns, landscaped areas, and under downspouts. Its listed connections support 3-inch and 4-inch sewer and drain, single-wall corrugated, and triple-wall pipe, as well as 4-inch DWV/Sch. 40 pipe. A drain grate fits on top.
Best for: Drainage plans that need two outlet connections from the basin. Choose it over a one-outlet model when the pipe layout calls for two exits. Limitation: The two outlets do not, by themselves, establish how much flow the system can handle; the product is described for light water flows and moderate stormwater runoff.
6-Inch Round Catch Basin Drain Kit
This kit is described as a 6-inch round basin with one outlet and a matching grate. Its listed purpose is collecting and draining light stormwater from lawns, patios, and walkways. It is compatible with 3-inch and 4-inch drainage pipes, which gives buyers more than one listed pipe size to consider when planning an installation.
Best for: Buyers who want a basin and matching grate in one listed kit for a light-duty yard or patio drainage point. Limitation: The product details do not specify the pipe types or provide installation instructions, so verify the connection requirements before purchasing.
Tempo 6-Inch Round Catch Basin
The Tempo product listing identifies a 6-inch round catch basin with one outlet. That makes it a potential option for a drainage layout designed around a single outlet. The available product information does not describe pipe compatibility, included parts, flow capacity, or installation details.
Best for: Buyers comparing one-outlet, 6-inch round basin options who can confirm the connection and included components from the product listing before ordering. Limitation: Because the supplied details are sparse, do not assume pipe-size compatibility or that a grate is included.
NDS 40 Grate Cover For 6-Inch Basins
The NDS 40 is a black plastic grate cover, not a complete catch basin. It is listed for NDS 6-inch Spee-D catch basin drains and fits specified 6-inch sewer and drain fittings and 6-inch single-wall corrugated pipe. Its openings let surface water pass while helping block leaves and debris from entering the drainage system.
Best for: Replacing or adding a compatible grate for light-flow drainage in a small lawn, landscaped area, walkway, or patio. Limitation: This product is a cover only; it does not include the basin described by the other products.
Buying Guide: How To Choose A 6-Inch Catch Basin
How many outlets does the layout need?
Choose a one-outlet basin for a plan with one pipe leaving the collection point. Select a two-outlet model only when the drainage layout calls for two connections. The outlet count is a physical layout feature, not a guarantee of higher flow capacity.
Which pipe size and type will connect?
Check the pipe diameter and material before choosing a basin. The NDS 101 and 201 list connections for 3-inch and 4-inch sewer and drain, single-wall corrugated, and triple-wall pipes, plus 4-inch DWV/Sch. 40 pipe. The basic kit lists 3-inch and 4-inch drainage pipes but does not specify pipe types. Confirm fit rather than assuming compatibility.
Does the package include a grate?
A grate covers the basin opening while allowing surface water to enter. The basic kit explicitly includes a matching grate, and the NDS basin descriptions state that a drain grate fits on top. The NDS 40 is a standalone cover, so it should not be mistaken for a complete basin kit.
Where will the basin collect water?
These products are described for light flows or moderate stormwater runoff around lawns, landscaping, patios, walkways, and downspouts. Consider where water gathers and how it will be routed downstream. Product details alone do not establish whether a basin is suitable for every site or storm condition.
Frequently Asked Questions
What does a 6-inch catch basin do?
It collects surface water through a grate and directs that water into an attached drainage pipe.
What is the difference between the NDS 101 and NDS 201?
The NDS 101 has one outlet, while the NDS 201 has two. Both are 6-inch round Spee-D basins with listed 3-inch and 4-inch pipe connections.
Can a 6-inch basin connect to a 4-inch pipe?
The NDS 101 and 201 list compatibility with several 4-inch pipe types. Check the individual product details and your pipe type before purchasing.
Is the NDS 40 a complete catch basin?
No. It is a grate cover intended for compatible 6-inch drainage components, not a basin-and-pipe assembly.
Are these products intended for heavy water flow?
The supplied descriptions refer to light water flows or moderate stormwater runoff. They do not establish suitability for heavy-flow conditions.
