A perc test description is in Appendix A of Kan-sas Department of Health and Environment (KDHE) Bulletin 4-2, Minimum Standards for Design and Construction of Onsite Wastewater Systems (K-State Research and Extension publication MF-2214). The water used for washing, dries off soon, without contamination of groundwater by pathogens as minimum distance of few metres is maintained between sources of drinking water and pit location. This reduces the quantity of solids and also changes its composition to sludge, which builds up in the bottom of the tank. The inputs and outputs of soak pits and cesspits are illustrated in Figure 3. Design Flows. It is an underground pit, filled with stones which filter solids that get slowly digested by bacteria. Caustic Soda Treatment (Emerging Technology) Caustic Soda Treatment is a cost-effective chemical treatment for faecal sludge from pits and trenches. 2.

DEWATS (Decentralized Wastewater Treatment System) is a wastewater treatment system that is both cost-effective and efficient, especially in poor nations. 1 A 100 HECTARE CATCHMENT A soak pit is a small, shallow pit dug in the ground to receive and treat wastewater. Waste water from our homes includes water from toilets, sinks, bathrooms, dishwaters and washing machines. 2 Residential Wastewater Characteristics 50 4. 1. B Y S W A P N I L PA U L INTRODUCTION • Septic tank is the underground, onsite, small scale sewage treatment setup, which collects the sewage for the decomposition activity by bacterial action. Infiltration is effectively a means to reduce stormwater quantity and peak flows, and to provide local recharge of groundwater. It is possible to also link a septic tank with a cesspit, such that the cesspit receives the effluent from septic tank. NYS Table 6: Seepage Pits / Soak Pits: Required Absoptive Area for Household Systems (Table body gives the required square feet of soakpit absorptive surface area). Contents [ show] WasteWater. . .
