What are the Guidelines for onsite Wastewater Treatment systems?
In the case of septage management, treatment can be done on-site or off-site. These are temporary solutions until a decentralized or comprehensive sewerage system is installed. It is strongly advised that town planning agencies/authorities/urban local bodies/metropolitan development authorities set aside appropriate area for sewer line laying, pumping station building, and treatment plant construction.
Sewage Treatment System-On-Site
On-site sewage treatment, unlike off-site centralized treatment (sewerage), includes individual and dispersed treatment.
A basic sanitation facility such as a pit latrine, a rudimentary sewage treatment system consisting of a septic tank and a soak pit for anaerobic and penetrating treatment, and an advanced facility that processes sewage using complex technologies are all part of the on-site treatment system.
In a densely populated metropolitan region, a sewerage system processes sewage gathered via pipes installed across a large area extensively, whereas an on-site system treats sewage close to its source. As a result, depending on the treatment scale and the surrounding conditions, the latter employs a variety of treatment technologies. Each on-site treatment unit generates sludge, which is collected and treated.
Guidelines to follow_
1: Installation and location
All systems must be installed and positioned in such a way that, with correct operation and maintenance, they do not cause sanitary nuisances or health concerns, and do not jeopardize the safety of any residential water supply, groundwater, or surface water.
1: A sufficient amount of space must be set aside for the treatment plant. At least 75 feet from a drinkable well and at least 100 feet from the mean high waterline of any water body (sea, lake, and canal), onsite systems must be installed. The location must adhere to the Planning Department's setback standards.
2: All treated effluent must be released into an effluent disposal well designed to the Authority's specifications.
3: A manhole must be provided in each compartment of a treatment system to enable for inspection and service.
4: All systems must be placed and installed such that they may be operated, maintained, inspected, and sampled. To prevent tampering or mishaps, systems should be deployed in a secure way.
5: If several systems are employed to meet the capacity requirements, they must be of similar size and implemented in parallel.
2: Flow design
-The total computed wastewater flows for all development (proposed and existing) on a specific parcel are used to determine the requirements for onsite wastewater treatment facilities.
-Plans must include scaled drawings that clearly show the nature of the design, dimensions, elevations, and details of all facilities and appurtenances, a schematic flow diagram showing the flow through various plant units, piping, and hydraulic profiles, as well as a schematic flow diagram showing the flow through various plant units.
-For all components, such as blowers, pumps, and diffusers, manufacturer's specification documents must be supplied.
-Aerobic Treatment Units (ATUs) are required for the treatment of all wastewater generated on a specific parcel if wastewater flows are projected to be 1,800 gallons per day or greater. The needed minimum ATU treatment capacity is equal to the computed gallons per day.
3: Trade wastewater
Domestic wastewater is the primary focus of wastewater treatment systems, whether central or onsite. Due to its concentration or contents, trade or commercial wastewater may interfere with, flow through, or disturb a domestic wastewater treatment system. The Water Authority will assess the suitability and kind of treatment for various forms of trade or commercial wastewater based on facility designs and specific production data.
