Water Byelaws compliance

It is important to consider The Water Supply (Water Fittings) (Scotland) Byelaws 2014 when planning a domestic development. These requirements apply to all plumbing systems, water fittings and appliances connected to the public water supply in Scotland. These standards ensure that water quality and public health are protected in both the property and the public water network

You have a choice of what option you wish to use to provide evidence of internal and external Water Byelaws compliance. The Water Byelaws (WB1) form will be sent to you with your technical audit quote. Please ensure you complete this form and send it to

A printable version of the WB1 form and an interactive version can be found here.

More information on Water Byelaws can be found here.

Surface Water Policy

For reasons of sustainability and to protect our customers from potential future sewer flooding, Scottish Water will not normally accept any surface water connections into our combined sewer system.

There may be limited exceptional circumstances where we would allow such a connection for brownfield sites only, however this will require significant justification from the customer taking account of various factors including legal, physical, and technical challenges.

In order to avoid costs and delays where a surface water discharge to our combined sewer system is anticipated, the developer should contact Scottish Water at the earliest opportunity with strong evidence to support the intended drainage plan prior to making a connection request. We will assess this evidence in a robust manner and provide a decision that reflects the best option from environmental and customer perspectives. Waiting until the connection request stage before consulting with Scottish Water risks refusal of the connection. Further details on Scottish Water surface water policy can be found in the
guidance document here.

Designing your connection

You are responsible for the design of private drains and new sewer connections. This design responsibility includes all the necessary consultations with roads authorities, SEPA, other relevant bodies and third parties.

We would advise you to employ a competent professional to assist you with the design of your site infrastructure to ensure the information you provide to us meets all requirements first time.

The first step in connection

A proposal for your connection design should be submitted to Scottish Water along with the relevant administration and inspection fee.

Please note that separate drainage systems are Scottish Water's preferred method of connecting to the public sewer and wherever possible surface water should be directed away from our existing combined sewers.

Our applications are available in our Applying for new connections section

Permit to Connect

When Scottish Water is satisfied with a proposal to connect to the existing infrastructure, a “Permit to Connect” will be issued. This is an approval to connect and will specify any requirement or conditions that we need you to comply with.

Scottish Water will also specify a time period for which this permit applies.  The connection must be made during this time period otherwise the permit to connect will be withdrawn.

Your contractor is responsible for all construction of your approved sewer connection, Scottish Water will need 5 days notice of work being carried out to allow us to programme a site inspection.

On satisfactory completion of all work the section of the pipe between the existing sewer and the boundary of the private property will be adopted by Scottish Water as part of the public network.
