PCSWMM Applications

Low Impact Development Design

Evaluate the effectiveness of Low Impact Development (LID), green infrastructure and other best management practices for reducing wet weather pollutant loadings. LIDs are integral to new development design and are also being widely retrofitted into existing developments.

Integrated Catchment/Watershed Modeling

Perform integrated catchment/watershed management modeling with ease, including constituent rural areas, river systems, urban sewer systems, treatment plants, ponds, LIDs and receiving waters. Plan, analyze, design and manage unified sewer systems integral with natural areas and drainage.

Water Quality Modeling

Generate accurate non-point source pollutant loadings for TMDL, NPDES, MS4, CMOM and related studies. PCSWMM provide tools that help design control strategies for managing polluted stormwater released to receiving waters – making it easier to design to meet water quality regulations.

Detention Pond Design

Easily determine the size and configuration of effective detention ponds and their appurtenances for flood control and water quality protection. Ponds may be arbitrarily shaped and distributed around the catchment – in series, parallel or both – and may be operated according to arbitrary rules.

Dual Drainage System Design

Design, model and analyze dual drainage systems for flood control in new, existing or combined developments. Surface flows routed overland (major systems such as roads, swales, street sags, storage areas) can easily and accurately be combined with underground flows (minor system, such as sewer infrastructure).

Sanitary Sewer System Design

Collection systems may be unlimited in size and number of control devices. PCSWMM facilitates the design and analysis of control strategies for reducing bypasses and fully supports the processing, manipulation and conversion of, and calibration against, observed data.

Stormwater Management & Sewer Remediation

Streamline the design and analysis of stormwater management control strategies for minimizing events such as combined sewer overflows, sanitary sewer overflows, water in basements, surcharging, street flooding and/or rainfall-dependent inflow and infiltration.

Flood Forecasting

PCSWMM Real-Time* provides accurate near-term (2–3 hours) and generalized long-term (24+ hours) forecasting of rainfall, runoff, flows and water levels. These detailed real-time models can be leveraged for other uses, such as floodplain delineations, remediation studies and master planning.
* At additional cost — contact us.

Floodplain Mapping & Risk Analysis

Dynamically model natural channels in rural and urban watersheds, taking into account flooded structures, backwater effects, spatially-distributed and dynamic rainfalls, groundwater interflow and flood inundation. Computed results can be animated in two-dimensions and projected obliquely in Google Earth.

Dynamic Storm Simulation

PCSWMM simulates dynamic storms with high spatial and temporal resolution. It fully supports the processing, calibration, manipulation and conversion of radar-rainfall data (e.g., rainfall disaggregation, discretization, transposition and more).
