Our new Infrastructure Charges Discount Scheme

Leaving a lasting legacy for future generations

At Severn Trent, the nature of what we do as a company means that we have an important role to play in protecting and sustaining water as a natural resource for future generations. This is why as part of our overall vision to be the most trusted Water Company by 2020 by our customers, we also have an ambition to become the most water efficient region within the UK. To achieve our ambition we want to encourage better water efficiency in the home to help our customers to save water and safeguard their homes from flooding- starting with new builds.  

We’re therefore inviting you, our customers, to be part of this ambition and in return, we will help you to save money on the cost of building your new home. We also want to show we're committed to supporting our housing developers in reaching the government’s target to build and develop 1 million new homes in the UK by 2020.

Our new Infrastructure Charges Discount Scheme could save you, as a home builder, money on both clean water and sewerage infrastructure charges by up to 100% if you build to our qualifying conditions.

Water is a precious resource that, in future, will come under increased demand as the population of the UK continues to expand. By thinking  and acting sustainably today we can ensure there’s enough for us all tomorrow.  We’d like you, our customers, to join us in our ambition to becoming the most water efficient region within the UK by reducing excess water usage in and around the home.  

To ensure the conservation of water, anyone building a new home within the UK must comply with Part G of The Building Regulations 2010. These regulations tell you that any new homes must be built to no more than 125 litres of water per person, per day (pppd) – however you can build to as little as 80 litres.

If you can show us that you have built to 110 litres (pppd) or less you can get a 100% discount on your clean water infrastructure charge – this means you pay nothing.

Water usage is easy to calculate – via the water calculator – simply tell the calculator you want to build to 110 litres and when selecting your fixtures and fittings (e.g. types of taps, bath and toilet) it will give you a list of products to choose from which allow you to meet this target.

The installation of the recommended fixtures and fittings will not only help save water and protect our environment - they could help you to reduce your future water bills if you’re a metered customer.

Ways you can tell us you’ve built to 110 litres:

Complete an application form for new service connections along with a copy of the results from the water calculator (confirming you are building to 110 litres per person per day) or a copy of the Part G Compliance Report.  

This only applies when the sewer connection is in the Severn Trent region.

Sewer flooding is one of our key measures for continuous improvement and it’s an area our customers ask us to invest in the most. Sewer flooding can be devastating to our customers when it happens, but the use of sustainable drainage systems can safeguard our customers’ homes from the risk of flooding caused by excess surface water.

There are many benefits of sustainable drainage:

  • Reduced risk of sewer flooding in your homes, streets and roads.
  • Less or no water is put back into our sewers, reducing pressure on our sewer network. This means less disruption in your area if we need to carry out repairs.
  • Having a ‘no surface water connection’ (such as a soakway) means any excess rainwater collected will feed back into the natural water cycle instead of going into our sewerage system to be treated.

We’re offering discounts to home builders who help us on our journey to reduce the risk of flooding in UK homes, streets and roads. There are two types of discounts on offer for sewerage infrastructure charges:

  • No surface water connection -  you can reduce your sewerage infrastructure charge by 100%
  • A surface water connection via a sustainable drainage system – you can reduce your sewerage infrastructure charge by 75%

Ways you can tell us about your sewer connections:

Complete an application form for a new connection where we will ask you for information on your sewer connections.

Please note: discounts against an infrastructure charge can be withdrawn or changed at any time and will be reviewed annually.
