Mission-Critical Facilities and Water Infrastructure for Federal and Military Environments
ESI has operated inside military installations since our first contract at Camp Pendleton. We did not adapt our services to this environment. We built them here. For decades, we have kept the facilities running, the water compliant, and the systems secure for the installations and the people who depend on them.
OUR SERVICES
Diverse solutions tailored to your every need
Every service ESI delivers in military and federal environments is built around one standard: the mission does not wait for a contractor to figure it out.
Built with excellence for those who serve

for the missions that cannot fail
What Sets ESI Apart In This Environment
How many contractors in this space publish their past performance ratings? ESI does. Our CPARS ratings are available because three decades of delivering in environments like yours produces a record worth showing.
ESI co-designed its wash rack recycling systems with the US Army Corps of Engineers and the US Marine Corps. These systems are built to military specification from the ground up, not commercial systems adapted for an installation. The difference shows in performance longevity. ESI-built systems from two decades ago are still in operation today.
Every person ESI sends to your installation is a part-owner of this company. That is not a culture talking point. It is a legal ownership structure that changes accountability at every level of the work. When ESI's partners win, the team that did the work wins with it.
ESI is the only contractor treating harvested rainwater to drinking water standards for military installations. This capability does not exist anywhere else in this market. For installations managing water independence or supplemental supply in constrained infrastructure environments, there is only one option.
Other contractors show up when something breaks. ESI builds programs that prevent the break. Scheduled maintenance, documented inspection history, and real-time monitoring that flags problems before clients experience them. When a compliance gap is approaching, ESI says something first.
ESI does not only sell standalone services. We provide integrated base operations support across facilities, water infrastructure, and security systems. One partner who understands how all systems interact, how they affect each other, and what happens when one of them fails. Nobody else in this space does this.
ESI maintains team continuity across contracts so the people on your site know your installation. They know where the utilities run, how the systems behave seasonally, and which problems are coming before they arrive. That knowledge does not reset with every new contract vehicle.
Every ESI engagement is documented to a standard that holds up under oversight review, regulatory audit, and congressional inquiry. Because decision makers who work with ESI should never have to defend a contract award to anyone.
Why Choose Us
ESI is the best I have worked with in going above and beyond. They are the very best I have worked with ever, and all the project managers in Marine Forces Reserve love ESI for exactly that reason.
