Being buried for centuries in the sewers and cesspits
helped preserve food traces -- Vesuvius' eruption also carbonized some food for posterity.
There are some important differences between a cesspit and a septic tank.
The cesspit or septic tank may be located within the boundaries of a property or may be within the boundaries to a neighbours' property and could be exclusively used by the property you are purchasing or used in common with other nearby properties.
According to excavation reports over 40 medieval cesspits have been found in Tartu (Tvauri 2008, 140).
The large number of different samples of wood has made cesspits attractive for dendrochronological dating.
Most of the cesspits found in Tartu are dated based on the find material to the period from 14th to 16th centuries, and in a single case, also to the 17th century (Table 2).
The distribution area of the cesspits discovered in Tartu (Fig.
Pirimiphos-methyl was evaluated at the dosages of 25, 50, 100 and 200 g(ai)/ha in cesspits. The lower dosage of 25 g(ai)/ha had been included in the trial to study the eficacy at a lower dose.
Evaluation and statistical analysis: Both in cesspits and drains, pre-treatment density was monitored at 2-3 day intervals, on day 10, 7, 3 and 1 prior to insecticide application.
Cesspits: The mean larval density (No./Dip) and pupal density (No./Dip) (average of 5 cesspits) ranged from 180.87 [+ or -] 27.93 to 195.45 [+ or -] 20.43 and 13.45 [+ or -] 3.46 to 31.00 [+ or -] 5.74 respectively during the pre-treatment period in cesspits selected for different dosages and control.
