Water and wastewater management

Castle Water has a proven track record of working with educational institutions, such as the Focus Trust Academy, Verulam SchoolQueen Elizabeth's Grammar School, and University College London, to help them better understand their water usage, identify issues and reduce costs. We can connect you with a wide range of water-related services to ensure you are getting the most from your water and wastewater services, such as:

Industry-leading trade effluent expertise

Trade effluent requirements can be complex, and trade effluent consent is a vital part of wider legislation which protects the environment. It is illegal to discharge trade effluent without consent and doing so carries the risk of prosecution and fines.

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.

Our dedicated team will provide your organisation with:

  • Full service support for correct consents and licenses and the application process
  • Wholesaler negotiation for bespoke consent limits
  • Guidance to meet regulatory obligations
  • Support and data reporting to help reach your sustainability and environmental targets
  • Tailored solutions for large and multi-site customers
  • Consistently accurate trade effluent billing

Consolidated billing

Consolidated billing provides a convenient way to receive and manage your multi-site costs in one simple invoice. This service is ideal for multi-site customers who wish to receive a single invoiced amount for all their water and wastewater charges, requiring just one single monthly payment. Depending on the size of your school or campus, consolidated billing could be the right option for you.

Standby water services

During water outages, we can provide standby water supplies to meet your needs. Whether it’s simply the supply of bottled water, or bulk supplies and tankered water, contact us and we can work with you to establish a continuity plan that meets your needs.

Direct Debit

A monthly Direct Debit is the easiest way to pay your bills and allows you to spread your water costs evenly over the year. Many customers choose to pay by monthly Direct Debit, just follow the quick and simple process here.

Meter reading

We take meter readings twice a year, or monthly if you are a large site or have a contract stipulating monthly reads. However, you can also provide additional meter reads yourself via our website (here) at any time.

We saved Focus Academy Trust £7.5K a year

Focus Academy Trust saved £7,500 on their annual water bill by switching to Castle Water as their sole water supplier, enabling them to reduce their water bills and re-direct funds towards front line resources.

Castle Water recovers over £13K in leak allowance for Verulam School

Award-winning customer service and fast leak repair

When a series of unexpected increased water bills indicated a leak, and call outs from private contractors were unsuccessful, Verulam School turned to Castle Water for support with leak concerns. Castle Water immediately organised a site visit to fix the unrepaired leak and completed a leak allowance application on the customers behalf. This resulted in Verulam School being granted a full leak allowance by their water network Wholesaler of over £13,600.

Kate Locke, Verulam School’s Business Manager, said: “I want to thank Castle Water for all your help in guiding us through this process and securing a leak allowance for the school. As you can imagine, the £13,629.20 allowance is a huge amount for a state school, and we are extremely grateful for all your support.”
