The lagoon may be round, square or rectangular, but a rectangular lagoon should not have a length of more than three times its width. It is normal for a properly sized lagoon to have a musky odor during warmer weather after prolonged periods of cloudy weather, ice cover or temporary overloading. Where soils are too gravelly or permeable to provide an adequate seal using soil alone, amendments may be added to improve the lagoon seal. Well-drained, medium-textured soils such as loam are best. Do not pave, build, pile logs or other heavy objects, or put a swimming pool over the drainfield. Seepage pits and cesspools are perforated tanks or pits lined with concrete blocks or bricks through which wastewater can seep into the soil. The better the soil type or greater the amount of absorptive trenches, the higher the system's capacity for wastewater treatment. If you assume that every person in the house uses 25 to 75 gallons of water a day, four people can fill a 1,500-gallon tank in five to fifteen days. Slope the pipe 1/4 inch per foot (1/8 inch per foot minimum) toward the tank. In fine clay or compacted soils, water moves too slowly. Remove loose material from the holes and add a 2-inch layer of 1/4- to 3/4-inch washed rock into the bottom of holes to prevent scouring when water is added.
