System Upgrade Underway: As part of our commitment to enhancing our customer experience, we are currently carrying out upgrades to our system. During this short period it may take longer than usual for your payments to be allocated to your account. We are aiming for payment allocations to be up to date by Tuesday 2nd June 2026.
Castle Water supports industrial businesses with reliable water supply and wastewater management built around operational needs. Large sites depend on consistent performance, clear cost control and compliance with strict environmental rules and we help organisations stay on track at every stage.
Our team works closely with industrial customers to manage usage, address high-volume demands and support discharge obligations, keeping site activity steady and predictable. We provide straightforward guidance on charges, trade effluent requirements and opportunities to reduce avoidable waste. With flexible services that scale across complex estates, Castle Water helps businesses plan ahead.
