Important Update: Engineering Department Closed to Walk-Ins
As of March 17, our Engineering Department and Water Services Department offices at 1265 S. Bascom Avenue has been closed to the public. Please know that our friendly and knowledgeable Water Services Team is still available to assist you by phone or by emailing engineering.dept@storesoo.com. If you currently have a new development project or service upgrade in process, please continue to work with your Water Services Representative via email.
The Water Services Department is a group of highly experienced individuals who work with developers, contractors and individual homeowners who need water facilities for domestic usage and fire protection. When you are considering your new water service needs please feel free to contact us early in the process. We can explain the procedure to apply for new service and discuss installation costs and construction time frames. Some jobs require that new facilities be engineered - which can extend the lead-time otherwise needed for installation.
