Whole water cycle simulation

SIMPOL ICM is a flexible, integrated, environmental modelling package designed for fast, long term simulation of the whole water cycle. It represents water resources, water treatment and distribution, driven by customer demand, and integrates with the urban wastewater systems and river catchments to produce receiving water flow and quality results in response to rainfall and temperature variations.

Our industry-leading consultancy services inform environmental regulators, water companies and industrial customers. We support water quality planning and permitting in surface waters, estuary, coastal and marine environments.

Key model features

Wastewater

• Integration of river and sewer systems
• Handles multiple wastewater discharges
• Accounts for drain-down times and follow-on storms
• Rainfall driven (which can be spatially represented)
• Sewer quality processes (e.g. dilution, build up and wash off, diurnal effects)
• Calibrated to InfoWorks results
• Handles correction factors for water quality standards
• Regulator approved

Agriculture and diffuse pollution

• Represents both agricultural and urban diffuse pollution
• Different land use types and wash-off loadings
• Fertiliser and pesticide rates and application periods

Resources and customer demand

• Models raw resources, reservoirs, treatment and distribution
• Identifies pinch points for customer demand exceeding supply
• Dynamic simulation of property types and occupancy rates
• Produces multi-decade projections (e.g., climate change)
