By 1982, rapid growth in the metropolitan area of Tampa, Fla., had increased the demand for water beyond the capacity of the city's only water treatment plant. Designated an AWWA American Landmark, the Hillsborough River plant had been enlarged three times previously since its construction in 1925. The latest expansion, which was completed last year, added 36 mgd (36,000 m3/d) of capacity without constructing new settling basins. Removal of hydraulic bottlenecks and improvement of flow patterns, rapid-mixing facilities, and the sludge removal system increased capacity without major new construction, saving about half the estimated cost of new settling basins.
