The Philadelphia Water Department (PWD) is organized into several different programs, each with various responsibilities and authority regarding land development. Many of the approvals needed from programs other than Stormwater Plan Review and Stormwater Billing and Incentives are related to water and sewer connections or instances in which PWD infrastructure is affected by a proposed development. Although the Development Services Unit will coordinate with other PWD programs throughout the review process, it is the applicant’s responsibility to ensure obtainment of all required approvals from applicable PWD programs and other City and State agencies before beginning construction. For more information on other PWD programs involved in the development process, the applicant is encouraged to visit the PWD Development Services website.
