Build a Treated Sewage Effluent District Cooling Make-Up Water Allocator

Evaluate treated sewage effluent availability against industrial district cooling tower evaporative losses and municipal irrigation constraints. Allocate secondary water volumes while enforcing fictional salinity and storage buffer rules.

District cooling utility water systems engineer

Ingest daily treated effluent inflows, cooling tower evaporative demands, and irrigation demand logs.

Model dynamic salinity accumulation and evaporative concentration across wet cooling towers using WaterTAP mass balance concepts.

Solve hourly allocation schedules under storage tank reserve limits and total dissolved solids constraints.

Export an operational water dispatch plan and flag unfulfilled volumes for potable water blending review.

A web dashboard displaying hourly storage levels, effluent distribution shares, salinity curves, and interactive allocation overrides.

Generate synthetic hourly time-series JSON files simulating 7-day cycles of sewage treatment plant outflow, cooling tower loads, and landscaping quotas. Starter examples below are synthetic. They are not downloaded records.

WaterTAP treatment modeling Applies flowsheet water mass-balance and dissolved solids concentration equations modeled after WaterTAP desalination and treatment flowsheet principles.

pydantic-ai, fastapi, numpy. Enforces strict type safety and schema validation across numeric flow rates, concentration limits, and multi-consumer allocation vectors. Local or hosted LLM with function-calling capabilities for constraint extraction and tabular water allocation summaries.

Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

Rejects allocation schedules that exceed maximum storage tank capacity or drop below 15% emergency reserve buffer.

Maintains cooling tower circulating water total dissolved solids below 2,200 mg/L by triggering potable make-up blending.

Outputs complete 24-hour balance reports where inflow equals consumption, storage delta, and blowdown discharge within 0.1% tolerance.

Simulation and scheduling tool only. Never directly actuate motorized valves or alter chemical dosing pumps in physical water facilities. Use mock external writes. Require human review before any real deployment.
