Locations where PWD has conducted surface water quality sampling and other types of stream assessments. Sampling activities may include water quality grab sampling, habitat assessment, and sampling of invertebrates, fish and algae from wadeable streams. Not all assessment activities are performed at all sites.

,Public Water Systems (PWS) submit their annual reports with rate information using the Electronic Annual Report (EAR) submission process on the Drinking Water Information Clearinghouse (DRINC) portal, which is reviewed, and manually updated into the Safe Drinking Water Information System (SDWIS). This includes the water rates reported by PWS in the EAR for years 2014 and 2015.,

A sewershed is the area of land where all the sewers flow to a single end point, in most cases it is a regulator/permitted outfall, but in cases when the flow can be split between multiple regulators/permitted outfalls, the area above the point of split is treated as a separate sewershed.

The primary purpose of PWD_PARCEL layer is to calculate parcel-based stormwater charges for PWD customers under the new parcel-based stormwater billing program. The layer was created from the DOR_PARCELS layer in 2005 after it was decided that none of the other City parcel layers could meet the needs of PWD's stormwater billing program. Those needs are generally that the parcel delineations match up to what people actually own, that there is an accurate assessment of the impervious area on the parcel, and that there is owner information associated with the parcel. Over the past 5 years, PWD has made corrections based off deeds on file with DOR, BRT information, and other City records. PWD also matched up each DOR parcel to a corresponding BRT record that contained the owner information for that parcel.

This layer is dissolved and queried from PWD's internal sewer shed feature class named modelsheds. The polygons in this layer are catchments for sanitary, storm and/or combined sewer flows. These catchments are used in the hydraulic models. Data DevelopmentBase Modelsheds are maintained regularly and delineate waste water and stormwater and combined sewer catchments in Philadelphia. Storm water and waste water pipe flow are analyzed to delineate the shed boundaries.

Collection Process: This data set reflects the recipients, award amounts, and project sites for grant money disbursed by the Philadelphia Water Department. It includes the Stormwater Management Incentive Program, the Soak It Up! Adoption Program Grant, the Green Acre Retrofit Program, and Business Incentive Program. These grants are funded by the Water Department but managed by separate agencies. Data Purpose: This data can be useful for non-commercial properties looking for assistance to reduce their stormwater bill. Intended Audience: It can also be useful to community organizations interested in serving as stewards of green infrastructure located in their area. And it can be useful to businesses impacted by PWD projects.

Public drinking water source areas (PDWSAs) are surface water catchments and groundwater areas that provide drinking water to cities, towns and communities throughout the state. PDWSAs are proclaimed under the Metropolitan Water Supply, Sewerage, and Drainage Act 1909 or the Country Areas Water Supply Act 1947. Groundwater sources are normally referred to as underground water pollution control areas or water reserves. Surface water sources are generally referred to as catchment areas. The PDWSA dataset is used by the Department of Water and Environmental Regulation in policy decision-making and for providing advice about protecting drinking water quality when land uses and activities are proposed in PDWSAs. This dataset was formerly known as Public Drinking Water Source Areas (DOW-007)
