Simplicity is a central tenet to the Rainkeeper approach. Our goal is to unite the age-old practice of collection and reuse of water with the latest technological innovations.



At Stark Environmental, we are not interested in creating systems that burden clients with a lifetime of maintenance costs. Instead, we strive to analyze every aspect of each individual project, and then design a system that will function in the most efficient and cost-effective manner.

By establishing direct-buy relationships, (many of them exclusive), with the highest quality product manufacturers, Rainkeeper is able to offer unmatched quality and value to their diverse clientele which includes corporate, educational, and municipal building owners, commercial and residential developers and builders, and private homeowners.

We are able to offer a range of products that meet a variety of budgets and needs – from a single tank or filter, to an entire commercial system complete with system design, preparation of system and submittal documentation, system installation and
coordination/oversight of involved subcontractors, custom control panel design and installation, system startup/testing, maintenance training.

Our background in construction grants us a clear understanding of budgetary concerns, building practices, and scheduling demands, as well as the logistics of working and communicating with subcontractors. We are dedicated to following the progress of each project from the design stage to the start-up and commissioning of the system. We
are committed to the long-term performance of our systems, and we routinely follow up
on projects after their completion.
