maintains two separate and distinct sewer systems. The Township
Sanitary Sewer System
This system uses a network of pipes to collect sewage from homes and businesses and channels wastewater into the Township’s pollution control plant before releasing it, after treatment, into Brush Creek. These conduits are fully enclosed and buried underground. Customers of the Township’s sanitary sewer service pay according to their volume of use. The system’s primary purpose is to protect public health.
This system collects rainwater runoff and directs it into local streams without putting it through the sewage treatment plant. Parts of this system are open to the surface and no one is charged for its use. The primary role of the stormwater system is to protect property against flooding and water damage.
Both the sanitary and stormwater sewer systems use a combination of private and public components. The design and construction standards are specified in the Uniform Construction Code of the Township Code of Ordinances and prior Township approval is required for all development plans.

Stormwater Management Plan
| Before 2002, rainwater runoff issues were addressed separately for each new development in Cranberry. However, as the surface contours of the Township continued changing with new development, the need for a coordinated, global, and comprehensive approach to handling storm water became apparent. In 2002, Cranberry implemented a plan to deal with flooding, infiltration/inflow problems, detention, and related stormwater drainage concerns.
That stormwater management plan targets the accelerated runoff resulting from land development and prescribes the construction of various swells, culverts, catch basins and detention ponds, as well as other water-handling facilities to channel and stage the release of rainwater to prevent downstream flooding.
The responsibility for maintaining these stormwater facilities is divided among homeowners, neighborhood associations, commercial property owners, the Township, and state authorities as follows:
