How does water get from the Kansas River to the faucet of the 170,000 customers Topeka Water Department serves? The answer is a multistep process that begins at Topeka’s water treatment facility just off of Interstate 70. The water is first pumped out of the river. It is sent to three large basins, where a polymer is introduced twice to encourage bonding between negatively charged particles. Pure chlorine is added next as the initial disinfectant. Ammonia is added to make chloramine, and then a flocculant is introduced to encourage clumping.
