Aim and Objectives of WWTP

  • Provide treatment to incoming wastewater
  • To provide maximum opportunity to reuse of treated water for horticulture or secondary purposes
  • To provide clean water to percolate into ground water tables
  • To create decentralised systems that will not put an extra load on centralised infrastructure.

Methodology of Designing a WWTP

Pond Reckey and Identification à Pond Profiling à Pre-Study (P           opulation study/ Water Tests/ Soil Tests/ Contour Maps/Demarcation of Private and Government Land) à Project Feasibility (based on the results of pre-studies, using a decision matrix of the land available, budget available, quality of wastewater, required operations and maintenance required à Best fit WWTP is decided) àDetailed Project Report à Administrative/Financial Approvals (Resolutions from authorities/ Funds acquired and sanctioned) à Civil Construction à Commissioning of WWTP.

Village NameTechnology NameDescription
BilaspurMBBRMoving Bed Biofilm Reactor – This reactor contains filter material that is stored within a tank. Aeration is provided, that allows the biofilm to develop as the wastewater trickles through the filter media.
KasanBiofilters + OzonationThe water is treated by passing through filters made of biological materials, and to allow prolonged disinfection of the water, passes through an ozonation tank.
Mojamabad/ Hariahera/ Tajnagar/ DhaulaPythorid BedsBiological treatment of water, as the wastewater passes through a bed of specialised plants, where treatment takes place by filtration through the layers of the soil strata, and biological treatment takes place at the root of the plants and the various microrganisms present in the soil
BudheraDEWATSThis system is based on anaerobic treatment of incoming domestic wastewater. The technology requires no major operations and maintenance, apart from the maintenance of plants in the constructed wetland. The treatment process is a multi-barrier system that allows for physical, biological and chemical treatment of wastewater
KhentawasAERAdvanced Eco-Reactor – The plant is based on the basic principle of trickiling filter, where the wastewater is sprayed over a bed of numerous layers of gravels, bio-filters such as coconut husks that are also initiated with enzymes that treat the water, that provide both physical and biological filtration. 
NawadaPhytoremediationThis technology is based on using both a biological consortia for treatment of wastewater, by passing through a tank containing carrier materials to increase the surface area in contact with the wastewater. Then the treated wastewater is passed through a root zone system containing aquatic plants as a polishing step to remove colour and odour from the wastewater.
