Advanced Greywater Filtration, Pressurization & Containment

Specifically designed for landscape irrigation.

The GreyLink  MDL and HDL Greywater Processors provide precise greywater filtration and pressurization for reuse in landscape irrigation. The two units are identical in function but do differ in a few select areas. Click Here for a comprehensive comparison.

Designed for Drip Irrigation

Precise Filtration, Wide Compatibility.

The GreyLink Greywater Processor has been specifically designed to prepare greywater to meet the filtration demands required for use in a high-pressure drip irrigation system. Dual-stage filtration consists of 150 mesh (100 micron) primary filtration followed by a 3-module secondary filter to meet the filtration requirements for .5 GPH self flushing drip emitters or larger.

Internal Components

MDL & HDL Series

Both the MDL and HDL GreyLink Greywater Processors contain the same components: the access cap, filter baskets, bolt down lid, filter carriage, spray ring, high pressure pump, pump switch and the polyethylene housing. certain specifications vary by model, but the mechanics and engineering remain constant. Precise greywater filtration, expandable storage capacity, automated operation and high pressure pumping are just a few of the many design and installation advantages unique to the GreyLink Greywater Processor.

Filter Access Cap with Compression Latch

Provides easy access to the filters without removing the bolt down lid


Primary Filter

Features a detachable 150 mesh (100 micron) stainless steel filter element


Bolt Down Lid

Provides a pump chamber which is tamper resistant.

Filter Carriage

Supports the primary filters and is easily removed to allow access to the pumping chamber

Self-Regulating Filter Wash System

Provides multi-point rotary spray to the primary filter ensuring that water flows freely through the filter element

Filter Flush Tubes

Automatically removes debris from the primary filter

Processor Shell

Provides protection for the internal workings of the GreyLink Greywater Processor as well as contains the greywater stored in the built-in reservoir

Filter Element

Debris Guard

Prevents debris from falling into the GreyLink Greywater Processor when the bolt-down lid is removed

Irrigation System

Supports multiple zones, scheduled irrigation times and advanced water usage reporting

Secondary Filter

Provides additional greywater filtration

Self-Cleaning Primary Filter

150 Mesh Filtration Captures All Inflowing Particles

Stage 1:

Filter Wash

The GreyLink's patent pending self regulating backwash system prevents lint and other greywater debris from collecting on the inside surface of the filter basket. The high pressure rotary spray nozzles are mounted on a flotation assembly which allows for constant cleaning at fluctuating water levels.


During times of excessive debris accumulation, debris-laden water is drawn from the bottom of the primary filters and sent out the overflow. To maintain maximum system efficiency, the filter elements are easily removed for occasional follow-up cleaning.

Stage 2:

Secondary Filter

150 Mesh Additional Filtration

Micro Lint Protection

Washing machines produce a tremendous amount of lint which is captured by the primary filter. During the process of filtration a small amount of micro lint is produced which will break apart during the primary filtration process and "clump" together in the greywater reservoir. The secondary filter effectively captures this micro lint within the dual stage filtration chamber.

Maintenance Protection

When occasional maintenance is required by the primary filter the secondary filter acts as a backup against any debris that could possibly fall into the greywater reservoir when the primary filter is removed.  With this backup in place the possibility of external debris clogging the drip emitters is virtually eliminated.

Performance Indicators

Visual System Status Indication

The GreyLink Greywater Processor's Performance Indicators provide a quick visual indication of system status.


When the system is functioning properly, both indicators will be fully extended. The tan indicator signals that the pump is running. The green indicator signals that the secondary filter is operating and the irrigation system is pressurized.

Greywater Treatment Options

Although most regional greywater reuse codes do not require any type of  treatment for bacteria or other dissolved compounds, some public-facing projects call for an extended degree of greywater treatment.


GreyLink provides two effective greywater treatment options which can be optionally added to both MDL  and HDL series GreyLink systems. The GreyLink ozone treatment system treats the greywater that is stored within the built-in reservoir. The GreyLink ultraviolet sterilizer treats the outflowing greywater and is located on the discharge line after the secondary filter.

High Pressure Irrigation Pumping

Accommodating Varying Pumping Heights and Distances

Whether the filtered greywater is intended to irrigate   lawn or planted landscapes of varying grades, the GreyLink pump is fully capable of transporting the water where it is needed while maintaining optimal water pressure. Refer to the Irrigation System Sizing Guide for detail on the pumping capabilities of the GreyLink system.

Supplemental Water

The water requirements for many landscapes is higher than the amount of greywater which is consistently produced on-site. The GreyLink system features a built-in auto fill sensor which is programmed to automatically add water from either a fresh water line or stored rainwater. This ensures that the landscape is irrigated properly regardless of the amount of greywater which is generated each day.






Built-In Back-flow Protection

The GreyLink auto-fill features a built-in air-gap which provides reliable back-flow protection to ensure that greywater will never be siphoned back into the potable water line or stored rainwater supply.

Expandable Greywater Storage

Modular Design, Endless Expansion Capability

Incorporated into both MDL and HDL GreyLink systems is a built-in amount of greywater storage. If more storage is required for the installation, additional add-on reservoir units can be connected to the system either during or post installation. There is no limit to the number of add-on reservoir units that can be attached to the GreyLink system.




Built-In System Overflow

Protects Landscape and Surrounding Area

Both MDL and HDL GreyLink Greywater Processors  include a built-in overflow port which is connected to the sewer or septic return. This feature allows for excess greywater to be diverted from the system in the event of a full greywater reservoir.
