Commercial Rust Control Frequently Asked Questions What is covered in the commercial service contract? Irrigation rust preventative, irrigation rust control system, maintenance of irrigation rust control system, and clean up of irrigation rust.  See Commercial Contract What is not covered in the commercial service contract?             In the commercial service contract, everything is included. What determines price?     See Price Sheet How does the system work? The rust control system is attached to your irrigation system.  When your well turns on to irrigate our pump injects rust preventative into the irrigation water, which neutralizes iron in the water. When is the existing rust removed? On commercial properties the initial rust removal clean up is performed within one month of installation of the irrigation rust control system.  This is because time is needed for the rust preventative to fully disperse throughout the irrigation system. How soon after the rust control system is installed will I notice results?             Immediately after the clean up is performed. What is PPM? PPM, or parts per million, is a way of expressing very dilute concentrations of substances.  Just as per cent means out of a hundred, so ppm means out of a million.  One ppm is equivalent to 1 milligram of iron per liter of water (mg/l). Can my ppm change? Yes, parts per million can change on a well.  This can happen for a number of reasons.  For example, construction or increased traffic near a well may cause a change, as well as drought or flooding.   MAKING FLORIDA BEAUTIFUL ONE PROPERTY AT A TIME!
