METHOD FOR AUTOMATED CONTROL OF A COMBINED GREYWATER/STORMWATER SYSTEM WITH FORECAST INTEGRATION

摘要

A forecast-integrated automated control system for combined greywater-stormwater storage and reuse. A simple and reliable approach for managing greywater and stormwater collection at a household or community level is provided, allowing for the near-continuous monitoring and adjustment of water quantity and quality in a combined greywater-stormwater storage tank based on monitored feedback/output from individual, tank-specific sensors and/or sensors located elsewhere in the water collection system. Use of the forecast-integrated automated control system for combined greywater-stormwater storage and reuse enables optimization of the water quality and quantity collected in the storage tank, reduce the amount of stormwater discharged to municipal sewers, and assure/demonstrate regulatory compliance for control of stormwater runoff through the integration of a low impact development best management practices.

主权项

1. A combined greywater-stormwater runoff capture and re-use system having a forecast-integrated automated control system, comprising:
a storage tank having a greywater inlet, a stormwater runoff inlet, and a drawdown outlet; a greywater collection system in fluidic communication with the greywater inlet; a stormwater runoff collection system in fluidic communication with the stormwater runoff inlet; a greywater bypass system, under control of the control system and in fluidic communication with the greywater collection system, for selectively routing greywater to the greywater inlet of the storage tank; a stormwater runoff bypass system, under control of the control system and in fluidic communication with the stormwater runoff collection system, for selectively routing stormwater runoff to the stormwater runoff inlet of the storage tank; a storage tank drawdown system, under control of the control system and in fluidic communication with the drawdown outlet of the storage tank for selectively routing liquid from the storage tank; and the control system in electrical communication with a source of weather forecast data for receiving the weather forecast data therefrom, wherein the control system is configured to control the selective operation of the greywater bypass system, the stormwater runoff bypass system, and the storage tank drawdown system in response to at least the weather forecast data.
