Water main diversion

What to think about before you apply:

• Are you planning to raise or lower the surface level during your development? (If so, we’ll need to assess the potential impact on our water network).
• Have you dug any trial holes on site or used ground penetrating radar to locate the water main? (If so, please provide the results with your application form).
• What was the previous use of the land you’re developing on? (Greenfield or brownfield?)
• If the land is brownfield, have you had a contamination assessment done?
• Is your development project notifiable to the HSE? (If so, we’ll need a copy of your F10 Notice).
• Do you want to hire a self-lay provider (SLP) to re-lay the main along the diverted route?

What you need to do:

• Apply for a water main diversion / disconnection using the link below.
• Make sure you include all the relevant supporting documents – these are listed with the application.
• Pay your application fee (£664.80 incl. VAT).
• Keep in mind that if a diversion is needed, there's a design fee of £4,314 (incl. VAT), which we'll invoice to you once we've processed your application.

What we’ll do:

• Get back to you within 5 days to let you know we’ve got everything, or if we’re missing any details.
• If needed, we’ll call you to arrange a survey of your site within 7 days of our call.
• Provide you with a design plan (if needed) and a quote for the works within 42 days of receiving your application (please be aware it could take longer if your site is complex).

What you need to do:

• If you’re happy with your quote, send us your payment via bank card, BACS or cheque.
• Make sure to pay your quote and book in the work (see Step 3) within the 6-month quote validity period otherwise you’ll need to request a re-quote based on next year’s charges.

What we’ll do:

• Process your payment and send you a VAT receipt within 24 hours.
• Send you a mains call-off request form to complete and return when you’re ready to book in the work (see Step 3).

• Email your completed call-off form to newmains@yorkshirewater.co.uk.
• Pay the admin fee of £678 (incl. VAT) for the call-off request once you've received the invoice.

What we’ll do:

Our delivery team will:

• Plan in the work and set a start date that’s within 90 days of your call-off (please note: this could take longer if we find we need to close the road).
• Call you within 7 days of your call-off to confirm the start date and arrange a pre-start meeting with you.
• Come to meet you on site before the agreed start date.

What you need to do:

Make sure you or your chosen contact is available on site on the agreed start date.

What we’ll do:

Our delivery team will come and carry out the following work on our behalf within 90 days of your call-off request:

• Disconnect the affected water main from the existing mains network.
• Re-lay the main along the diverted route according to the design plan.
• Connect the main back up to the existing mains network.
• Backfill and reinstate any excavations made during the works.

Disconnection only:

• Disconnect the affected water main from the existing mains network and decommission it.
• Backfill and reinstate any excavations made during the works.
