Overview

Leading The Industry For Drywell Systems

MaxWell enables engineers to manage stormwater more effectively and efficiently on site, providing collection, storage and deep infiltration of surface water runoff to mitigate flooding, prevent downstream pollution and replenish groundwater supplies. 

With each system providing 43,000 sq ft of drainage and up to 2,500 gallons of storage in a drywell shaft just 4ft in diameter, no other technology provides comparable drawdown speed and storage in such a small footprint.

With over 70,000 systems installed since 1974, MaxWell is a proven, effective solution, and our expert teams take care of design and installation—helping contractors to save time, reduce cost and improve safety on site.

Mitigate flooding, capture pollution and recharge groundwater in a single system

  • With fast drawdown speed, impressive collection volume, integrated treatment and optional pre-treatment, engineers can trust MaxWell to provide flood mitigation, pollution capture and deep infiltration capabilities in a single compact, small-footprint system.

Meet stormwater quantity and quality regulations

  • With rapid collection and impressive storage, MaxWell is optimized to meet Arizona’s demanding flood management regulations, and with optional pre-treatment filtration verified by NJCAT and certified by NJDEP it can also meet stormwater quality regulations. And with an install base of over 70,000, MaxWell is proven where it matters most: in the field.

Retrofit easily into existing infrastructure

  • In parts of the country our below-ground infrastructure network has becomes congested, making effective underground stormwater storage and infiltration difficult or impossible to achieve. With a diameter of just 4 ft, MaxWell provides a precision solution that cuts through cluttered underground systems to deliver deep infiltration in even the most challenging of infrastructure environments.
