Water Storage, Pump Access and Water-Level Management in One Compact Underground Tank

Made in the USA

The HydroChamber™ combines pondless water storage and pump access in one compact, direct-burial tank.

Instead of storing water throughout a large underground reservoir filled with structural blocks and decorative rock, the HydroChamber stores the system's operating water in a dedicated tank where the pump remains accessible.

Smaller Excavation • Accessible Pump • Dedicated Water Storage • Auto-Fill Ready • Remote Installation Capable

HydroSieve™ pre-filter connected to an underground HydroChamber™ showing debris removal, water storage, submersible pump access and automatic water-level control.

HydroChamber™ at a Glance

  • 37" tall × 26" diameter
  • 75-gallon total tank capacity
  • Approximately 50.9 gallons of water storage above the pump
  • Two standard 2" female threaded outlet ports
  • Standard 2" outlets accommodate 1½" or 2" pump plumbing
  • High Flow Rates: 6" gravity-fed inlet → additional 3" pump outlet
  • Second 2" outlet can serve a second pump or system overflow
  • 4" or 6" gravity-fed inlet
  • 4" tank-to-tank connection for additional water storage
  • Auto-fill ready with dedicated ½" female threaded water-supply port
  • Direct-burial rotational-molded HDPE construction
  • Supports more than 450 lbs.
  • Multiple HydroChambers can be connected for additional water storage
  • Multiple-pump capable
  • Compatible with submersible and external centrifugal pumps
  • Remote installation capable

Designed to Match the Pump's Flow Rate

The HydroChamber™ can be configured for a wide range of pump flow rates and water-feature sizes.

Smaller Flow Rates: 4" gravity-fed inlet → 1½" pump plumbing
Mid-Range Flow Rates: 4" gravity-fed inlet → 2" pump plumbing
High Flow Rates: 6" gravity-fed inlet → 3" pump plumbing

Rather than forcing every installation into the same plumbing configuration, the HydroChamber can be matched to the flow requirements of the pump and water feature.

Need More Water Storage? Add Another HydroChamber™

Multiple HydroChambers can be connected through their lower 4" tank-to-tank connections, allowing the chambers to share stored water.

As the size of the water feature—and the amount of water that returns when the pump is turned off—increases, additional HydroChambers can be added to provide the required storage capacity.

One pump or multiple pumps. One HydroChamber or multiple HydroChambers. The system can grow with the water feature.

One Tank. Several Jobs.

A pondless system needs more than a place for the pump.

It needs water storage. It needs convenient pump access. It may need automatic water-level control. And it needs a way to manage overflow.

The HydroChamber™ brings those functions together in one compact underground tank.

Water Storage • Pump Access • Auto-Fill Connection • Overflow Management

Because the pump operates inside a dedicated water-storage chamber, it remains accessible without being buried beneath decorative rock or located inside a gravel-filled reservoir.

Why Dig a Larger Hole Than You Need To?

Traditional rock-and-gravel pondless reservoirs store water throughout an underground basin containing structural blocks, a slotted pump vault and decorative rock.

The HydroChamber™ takes a different approach.

Water storage is concentrated inside a dedicated underground tank while the HydroSieve™ removes debris before the water reaches the pump.

That can mean a smaller excavation, fewer reservoir components and easier access to the pump and stored water.

Less Excavation • Fewer Components • Easier Access
