One simple bill

We keep billing fuss free. One simple bill for your business water and wastewater means you can spend more time where your needed most, and less time dealing with bills. And with MyAccount, you can log in to see everything all in once place.

Consolidated billing

Does your business have multiple sites? If so, Castle Water can provide you with one simple bill for all consumption and charges, for all your meters in one invoice to save you time and money. This service is ideal for large, multi-meter and multi-site customers who wish to receive a single invoiced amount for all their water and wastewater charges, requiring just one single monthly payment.

Consolidated billing also makes it easy to manage your costs. It is easier to view and compare water usage over time and across different sites, helping you to identify irregular consumption levels and potential opportunities to improve water efficiency.

Trade effluent requirements can be complex. Castle Water’s dedicated, expert trade effluent team has the experience and technology required to understand it like no one else – and we make the process simple.
