Opening the pool and filling the pool with water are the only things holding back the family fun. The last time you tried to fill the above ground pool, the water started off brown and ended up somewhere near a cranberry cocktail. Small above ground pools contain over 1,000 gallons of water, and large pools hold 10 or 20 times that amount. Although pools require thousands of gallons of water, the logistics of filling a swimming pool aren’t overly complicated. You just need to know what your options are.

You can fill hot tubs and small above ground pools with a hose. However, larger pools with 6,000 to 10,000 gallons will require water delivery. For homeowners in rural areas, there is a risk of overheating the well pump if it’s worked continuously. Water supply companies delivery water by the truck load in tractor trailer tanks that hold 5,000 gallons. Tankers are great for large pools, but it’s hard to negotiate rates for smaller deliveries. Depending on the area and provider, water supply companies may charge $150 to $300 per delivery. Before ordering water, check with local fire departments in your area to see if they offer pool filling services. The typical fire truck holds 2,000 gallons and fire departments might charge less than commercial water supply companies.

Iron, manganese, and calcium are naturally present in tap water. These elements contribute to hard water. When chlorine and tap water mix, metals form rust that stains dark brown and red. These oxides can leave serious stains on pool walls and equipment. To prevent metal stains, use a chelating and sequestering product that attracts metals. These products are sold under a variety of names, including stain remover and calcium controller. After filling with municipal water and using a sequestering agent, wait three to four days before super shocking.
