Developers & Contractors

Department of Water Management staff members in a number of divisions interact with developers and contractors on a regular basis. Utility Engineering staff review plans in the Land Development Office (LDO) process to evaluate impact of projects on the City’s water and sewer systems. The process starts with the Development Office in the Public Works Department.

The Cross-Connection Control (CCC) and Industrial Waste Control (IWC/FOG) staff also review plans in the LDO system. CCC staff review plans to make sure that the appropriate backflow preventer devices have been selected for the project. Staff tracks the plans and inspect installations before the Certificate of Occupancy (CO) can be issued. CCC staff also issue the permit for the backflow prevention installation.

IWC/FOG staff review plans for food service establishments to ensure that grease interceptors are appropriately sized and located for routine maintenance. Making sure that adequate devices are in place helps to reduce the potential for sewer overflows and blockages due to grease build-up in the sewer collection system.
