Capital cost correlations are given for aeration basins, mechanical aerators, diffused aeration, conventional activated sludge process, extended aeration, contact stabilization, oxidation ditch, rotating biological contactor, trickling filter, aerobic lagoons, facultative lagoon, aerated lagoons and liners. Most of the correlations are accurate to ±30%, expressed in Canadian dollars and adjusted to a Marshall and Swift value of 1000. Details as to what components are included in the cost are given. Data are given for the labour and material costs to create a working process module. Data for oxidation ditches are accurate to ±50%. To put the current data into perspective, several hundred sources of cost data were analyzed. The major correlations are compared, on a consistent basis, with current data.
