About Us


Or, RWS for short.

We Provide Commercial Water Heating Equipment and Services.

Reliable Water Services provides custom rental and service plans for water-related commercial equipment – water heaters, boilers, water softeners & more – to businesses throughout the entire states of WI and IN, as well as select portions of IL, MN and OH. We specialize in helping businesses where a lack of hot water has a critical impact on their ability to operate.

Our 24/7 Rental and Service plans are used across a wide variety of different industries that require hot water. The emergency services we provide are perfect for the hospitality industry because restaurants and hotels need and use a lot of hot water. So do breweries and food manufacturers. We are also quite helpful in apartment buildings, healthcare facilities, schools, salons and more!  And, we’re available for service 24/7 because that’s when our customers need us.

Equipment rarely breaks down during standard “business” hours. Our job is to ensure our customers always have hot water when they need it. We have built strong, trusted partnerships with local service providers and distributors throughout our coverage areas. When equipment fails we minimize downtime by sending trained service techs with parts on-hand to get water heating equipment fixed or replaced as quickly as possible. All for a manageable monthly payment that’s easy to budget and typically tax deductible as an operating expense.

We are committed to refining our internal operations to ensure our established policies & procedures are equally beneficial to our customers and our company.



Our company has deep roots dating back over 50 years to its founding in 1966 as Wisconsin Gas Leasing Services (WGLS), a division of the Wisconsin Gas Company.  The unit was founded to promote the use of gas appliances in Wisconsin, providing new financing options to encourage customers to upgrade their old water heating equipment.


WICOR, local holding company of Wisconsin Gas, became part of Wisconsin Energy, creating the largest electric and natural gas provider in Wisconsin. After the merger, the company began realigning their overall goals to focus on their core business of providing more power sources for Wisconsinites.


Wisconsin Electric-Wisconsin Gas officially changed its name We Energies. They also decided to sell the Wisconsin Gas Leasing Services division to a group of investors that was dedicated to maintaining the mission of providing affordable hot water solutions to customers throughout WI. And in June 2002, WGLS officially became Wisconsin Leasing LLC.


Now an independent company, we were still focused on keeping our customers in hot water, but we were also offering additional water-related equipment like softeners and boilers. And we thought the name “Wisconsin Leasing” was simply too vague. So we re-branded to better reflect our mission and changed our name to Reliable Water Services LLC (“RWS”) in November of 2005.


In May 2009, RWS acquired the assets of a similar business that had been a division of a gas company in Indianapolis, expanding our team and extending our service coverage area to the entire Hoosier state.


We decided it was time to refresh our look, so we redesigned our logo and freshened up our color scheme. Our new RWS monogram logo was created to visually symbolize that “hot water” is still at the core of our business.


In January 2018 we finished relocating our corporate offices to 3rd & Wisconsin, in the heart of Downtown Milwaukee, WI. This move to the city’s center allows us to better serve our customers by bringing us closer to a variety of resources, like having our own equipment warehouse located within walking distance. And, we are now centrally located in between multiple major plumbing distribution houses, allowing more efficient access to needed parts for nearly every water heater brand out there.
