WaterFuture - Get into water

Tap water is precious - why use more than you need?

Come rain or shine, saving water makes sense. Water is a finite resource that we share with the environment. Every litre of water saved is a litre returned back to the environment. The less water we use, the more we can keep our rivers and streams flowing and nature thriving.

The more we have to treat and distribute, the more it costs. Using less helps the environment and will save you money if you have a water meter (use less, pay less!).

Save water in your home

  • Turn off the tap while brushing your teeth
  • Keep a jug of water in the fridge so you don’t have to run your tap cold
  • Use a bowl for washing up / rinsing fruit and veg – then use this water for plants   
  • Have a shower instead of a bath
  • Only use your dishwasher or washing machine when you have a full load (this will save money on your energy bills too)
  • Only fill the kettle with as much water as you need (this will save energy too)
  • Fix leaking taps and toilets

Codes for Adoption

What are 'Codes for Adoption' ?


The Water Act 2014 introduced changes to the Water Industry Act 1991 (WIA91) requiring Ofwat to issue statutory codes for adoption agreements. These are the agreements that developers or self-lay providers (SLPs) enter into when they want an appointed water or sewerage company to take over responsibility for infrastructure they have constructed. They are the agreements entered under section 51A WIA91 for water infrastructure.


The codes were introduced by Ofwat to ensure a consistent approach in the sector, that developers, new appointees and SLPs, are provided with confidence that they will receive the services they want from water companies to enable their own business in providing contestable services.


The water code documentation was approved by Ofwat in September 2020. The approved set of documents can be found below and also on the Water UK website.


Codes for adoption will go-live from 1 January 2021.


In preparation, all water companies are required to publish certain documents.


We are pleased to share our documentation below, which we will continue to add over the coming weeks.


Design and Construction Specification (DCS)

The South West Water Draft Design and Construction Specification can be found here.


Local Practices

The DCS allows South West Water to introduce a local practice in certain permitted areas where our operational requirements are not adequately covered in the document. Our draft local practices are contained within the Design and Construction specification and highlighted blue. If you have any thoughts/comments on them, which you want to discuss, please email them to developerservicesselflay@southwestwater.co.uk .  We will then publish our finalised version by the 1st January 2021.


Annual Contestability Summary (ACS)

The connection work that is open to competition is known as “contestable” work. This category includes the majority of work a Developer needs to serve a new development and includes all work to lay and test new mains and services. Water Companies have a responsibility to maintain wholesome water supplies to Customers, some higher risk work may be defined as “non-contestable” and can normally only be carried out by the Water Company itself.


We will publish our ACS each year and evolve the document to enable further contestability each year.
