Project Partner Beautiful Nepal Association (BNA)
Project Location Birendranagar, Surkhet
Project Duration Dec 2021 - Dec 2021
Description Faecal sludge treatment plant is integral for safe management of faecal sludge collected from onsite sanitation systems which gained large popularity to achieve the target of an open defecation free (ODF) region. Nepal was declared an ODF country in September, 2019. In this context, recently FSTPs are being established in many municipalities of Nepal. Birendranagar Municipality located in Surkhet district in Karnali province of Nepal also has established a FSTP under the support of WASH SDG Programme of SNV to offer safe treatment and disposal of human excreta services to the city’s 116000 inhabitants. It consists of various treatment units including screening unit, vertical flow constructed wetland, and composting units. BNA under technical and financial support from SNV intends to observe the performance of the Birendranagar Faecal Sludge Treatment Plant (FSTP) by studying characteristics of inlet, outlet from different components and the final treated effluent from the system through analysis of various parameters. The concentration of these parameters are also useful in comparing quality of treated effluent with national standards for treated wastewater as indicated in “Tolerance limits for Wastewater to be Discharged into Inland Surface Waters from Combined Wastewater Treatment Plant” published in Part III, Generic Standard, 2060/03/09 (See annex 2). BNA has therefore assigned EcoConcern with the assignment of collecting samples of faecal sludge and wastewater from Birendranagar FSTP from various points of the plant and conduct their laboratory analysis.
Objective:
The main objective of the assignment is to provide a brief report on characteristics of sludge and wastewater collected at FSTP in Birendranagar, Surkhet based on tested parameters.
The specific objectives are listed below:
- To collect samples for laboratory analysis from following four different points of the FSTP as designated by BNA
- One raw faecal sample received at inlet of the FSTP i.e. collect raw samples directly from outlet of desludging trucks
- Two samples from two wetlands in the system; one from each
- One treated effluent sample from the treatment plant
- Provide lab test reports for provided 8 parameters namely pH, Biological Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), Escherichia coli (E. coli), Total Suspended Solids (TSS), Total Nitrogen (TN), Total Phosphorus (TP) and Potassium (K)
- Provide a brief report on field activities conducted and findings from laboratory analysis
