The collection system includes gravity sewer mains, lift stations and force mains throughout the city that direct the sewer flow to a master lift station at the lowest elevation in the city. From that point all effluent is pumped to a regional treatment works operated by the City of Waco under contract with the Cities of Waco, Bellmead, Woodway, Lacy Lakeview, Hewitt, Lorena, and Robinson. The City's contract allocation in the plant ranges from a minimum of 0.4 million gallons per day to a maximum of 1.3 MGD.
Current Flow Average
At present, the average flow is 1.08 MGD, allowing some capacity for growth. Meanwhile, work is underway to add capacity at the central treatment plant and construct a satellite treatment plant south of the city, adding even more room for growth. There are 5 personnel assigned to this function. Major construction work is contracted to the private sector under the supervision of the City Engineers.
