MISSION CRITICAL PROJECT No. 4:
THE PURPOSE OF THE MANHOLE REHABILITATION PROJECT WAS TO CORRECT (BUT NOT LIMITED TO) THE SERIOUS ISSUES OF INFLOW & INFILTRATION (I&I) THAT CONTRIBUTED TO: SEWER OVERFLOWS, AND THE SIGNIFICANT AMOUNT OF GROUNDWATER & STORM WATER FLOW TO SEWER TREATMENT PLANT (= BEYOND DESIGN CAPABILITY OF THE PLANT). THE I & I ISSUES DEGRADED THE OPERABILITY, RELIABILITY AND AVAILABILITY OF THE SEWER SYSTEM INFRASTRUCTURE. ONE INDUSTRY STUDY CITED THAT DUE TO I & I, ONLY 30% OF FLOW TO TREATMENT PLANTS IS ACTUALLY SEWER.
SEWER MANHOLE’S CONCRETE DETERIORATION WAS DUE TO MICROBIAL-INDUCED CORROSION, OR MIC. IT IS A PROCESS WHERE AN AEROBIC BACTERIA, FORM IN RAW SEWAGE EFFLUENT AND NATURALLY CREATES HYDROGEN SULFIDE GAS, OR H2S. THE H2S GAS IS THEN METABOLIZED BY AEROBIC BATERIA WHICH CREATE LARGE QUANTIFIES OF SULFURIC ACID IN THE PRESENCE OF OXYGEN. THE SULFURIC ACID IN TURN ATTACKS EXPOSED CONCRETE AND UNPROTECTED SURFACES OF IRON, STEEL AND COPPER, RESULTING IN CORROSION AND DETERIORATION OF THE EXPOSED VULNERABLE MATERIALS.
MADERO’S WARREN EPOXY HAS BEEN SUCCESSFULLY APPLIED OVER MANY THOUSANDS SEWER MANHOLES IN THE PAST THIRTY YEARS AROUND THE WORLD. OUR WARREN EPOXY IS AN APPROVED PRODUCT BY THE CITY OF HOUSTON’S PUBLIC WORKS & ENGINEERING FOR SEWER SYSTEMS REHABILITATIONS. FURTHERMORE, AND DUE TO ITS OUTSTANDING PERFORMANCE AND PROVEN TRACK RECORD, WARREN EPOXY HAS BEEN APPROVED BY MUNICIPALITIES AROUND THE WORLD FOR POTABLE WATER & SEWER SYSTEMS APPLICATIONS. TESTIMONIALS OF SATISFIED CLIENTS CAN BE PROVIDED UPON REQUEST.
