Scottish Water
Scottish Water's Development Operations department handles a variety of tasks related to water supply and waste management for development projects. They provide support and guidance for new water and wastewater connection applications, disconnection requests, and diversion or build-over applications. Additionally, they supply Distribution Operation & Maintenance Strategy (DOMS) documents for contractors and developers. The dedicated phone line operates Monday to Thursday between 08:00-16:00 with a lunch break from 12:30 to 13:30, and Friday 08:00-14:00, allowing developers to discuss detailed planning or address queries during these hours. It is advisable to avoid calling during peak periods to mitigate the risk of long wait times, commonly reported during technical consultations.

Known issues
Callers sometimes face long wait times during busy hours, particularly for complex technical queries. To avoid this, it's wise to contact outside peak hours or opt for communication via email for non-urgent matters. Additionally, users occasionally report difficulty accessing the online portal needed for application submissions. If these difficulties arise, contacting Development Operations directly by phone or email to seek manual assistance is recommended. Always ensure you have precise site plans and technical documents ready to expedite your request, either through the portal or manually.
