Castle Water is dedicated to cutting your costs
We are passionate about meter readings and always will be, and that is because we champion accurate billing for our customers. Unlike some other retailers that bill in advance based on estimates, we bill in arrears based on actual usage. That is our commitment to you.
Businesses are under real pressure to control costs. We take that seriously — and we’re committed to being part of the solution, not the problem. We continue to invest in systems and promote the installation of Automatic Meter Reading (AMR) devices so that managing your business water only gets easier.
