<p>A self-contained water quality enhancement apparatus is provided for purging a low flow area of a subterranean water distribution system. The apparatus includes: a water carrier system (112) for transporting water through the apparatus, a flow control valve (119) for adjusting the flow rate of water through the system, a programmable solenoid controller (131) for activating and deactivating the flow control valve, electronic and/or optical sensing devices (120) for measuring water quality, a data access and programming port, and an electronic control system. The components cooperate to provide a means for automatically measuring water quality and then purging water from the low flow area as required.</p> |
