Today, we built some watersheds that included Lake Whatcom (our drinking water source) and its surrounding terrain, the water treatment plant, a supply pipe to take cleaned drinking water from the water treatment plant to a storage tank, and pipes to take cleaned drinking water from the storage tank to houses, houses and streets, sewer pipes to take wastewater from houses to the wastewater treatment plant, a pipe to take treated wastewater from the wastewater treatment plant to Bellingham Bay, and of course, Bellingham Bay (where all the water we use ends up)!
