The water treatment system may include multiple sub-systems for treating water that feed into one another. The sand filter system may include a mini bio-sand filter, a foam filter, or a pressed block filter. The flocculation system may include a tank bottom that urges settling particles toward a sump and a ladle that removes settled particles. A manual pump or siphon may be included in the water treatment system.
