Currently more than one-third of the nation’s wastewater treatment is provided by septic tank. A septic tank is basically a vessel buried undergroun the purpose of which is the collection, storage, an to some limited extent, treatment of sewage. Surface and subsoil water should not enter into the tank. The solid waste, paper, napkins should not be flush to avoid the blockages. The kitchen water should not be run in the septic tank.

KDHE bulletin 4-2: Minimum Standards for Design and Construction of Onsite Wastewa-ter Systems fulfills that purpose. The capacity of septic tank depends on number of users and interval of sludge removal. Normally sludge should be removed every years. The liquid capacity of tank is taken as 1liters to liters per head. For small number of users 130ltr per head is taken.

This revision incorpotxtes the following major changes. Your septic tank and drainfield area(s) should be clearly designated on the “as- built” drawing for your system. Septic Tank Pumping and More. An “as- built” drawing is a line drawing that. You might also see lids.

Since septic tanks have sealed walls and floor, the design must be checked to make sure that the tank does not float out of the ground. Flotation will occur if the total mass of the empty septic tank is less than the mass of the water it displaces. This will only happen if the groundwater level is higher than the bottom of the tank. Here we look at the design and construction of a septic tank , we povide building plans for a standard sized tank and we discuss the features, the need to determine effluent levels the tank inlet and outlet pipes, the transfer pipe between the internal chambers, vent pipes and the design.

The ABCs of septic tank and drainfield design : This septic system design article outlines basic septic system design parameters such as finding the recommended septic tank volume and conventional recommended onsite wastewater soil absorption system (leach field or drainfield) size, along with some notes on how to calculate these from simple water usage and site conditions.
