Home, - Cost-Benefit Analysis


CBA is an economic practice that is utilized to public decision making which try to enumerate and associate the economic benefits and costs linked with a certain project for society in its entirety. The appeal of Cost-Benefit Analysis is that through monetizing the welfares of the project, it is probable to associate and/or collective many varied groups of benefits with each other, and with the expenses of the project. Based on many alternative packages being inspected, Cost Benefit Analysis would endorse selecting the one with the main net advantages; net advantages/benefits are outlined as the benefits deprived of the costs. CBA – or more precisely, the approximation of costs and benefits that is obligatory to achieve a Cost Benefit Analysis. Similarly, it allows one to control the socially optimal quantity of the program.

Diverseapproaches to wastewater management are required in different parts, urban and rural, with diverse levels of economic growth,demographic masses, technical size and management approaches(Massoud, Tarhini and Nasr, 2009). Techniques may differin regard to the quality standard needed in the end point disposal and end users. The healthstandingsoffer a valuabletoolfor measuring the state of sanitation at local level, region or municipality, directingbest wastewater treatment approaches. It is imperative that wastewater treatment methodscreate the basing for development and planning process, illustrating localactualities and cultural variations and externalities like acquaintance to natural threats or thrillingsituations. Incremental methods to wastewater treatment may result in long-term achievement. 

Wastewater is everybody’sworry at work and in home. Creation of awareness and education has great influence on the actions to minimize wastewater release and also reflect the chances of supervisionwith wastewater in a manner that financially viableand environmental friendly which may work as a good solution(M, 2015). Good indulgent of the connection between health,wastewater, food production, ecosystem functioning, and potential importance of wastewater recycle in improved and development of welfaremay raise approval of ingenuities. It is significant that training and education in efficientcommitment of stakeholders and wastewater management in everypart throughout the whole project process is sociallyprecise and demonstrates or proposesresolutions which may be adapted to suit diversesituations. Awareness, education, stewardship, and advocacy need to be put in place at numerousstages including the improvement of professional abilitiesto develop multi-year financial preparation and inter-sectorial partnership.

Costs and Benefits Analysis 

CBA’s key role in an incorporated valuation is in Phase III through supporting the assessment of other options. In a comparatively well−organized problem, Cost Benefit Analysis may as well be applied to support target setting, that is phase II, in the event that it is probable to quantify costs and benefits to a adequate degree. Cost Benefit Analysis may as well be used in Phase IV as an ex post valuation of a certain policy.

Cost Benefit Analysis’ application in an integrated assessment gives number of questions. To start with, Cost Benefit Analysis measures costs and benefits on the base of individual partialities provided objective supply restraints and technological potentials. Whether or not a policy that exploits  individual favorites is ‘sustainable’ is an uncluttered question  and need to possibly be answered on a case−by−case grounds.

Second, Cost Benefit Analysis is frequently critiqued for its seeming thoughtlessness to concerns of intra− and intergenerational equity. A third regarding the subject of intra−generational equity, Cost Benefit Analysis is unresponsive as to the delivery of cost and benefits over dissimilar persons, as long the ‘winners’ may, in code, recompense the ‘losers’.

Third, in Cost Benefit Analysis doubt and danger are preserved in a classical fashion. In the event that the certain future belongings are indeterminate, the correct process is to assess the predictable utility of the belongings. Concerning the approach, the likelihood and the magnitude of the belongings play a role, nonetheless as well the rate of danger aversion of the pertinent population

Fourth, convinced costs and benefits in the social and ecological domains of maintainable development might be problematic to calculate and to value in monetary aspect. There exist observers with objection in principle to the view that each ‘value’ might be dealt for a price. Nonetheless placing these moral oppositions aside, in the exercise of Cost Benefit Analysis progressive ‘valuation’ apparatuses have been advanced that are proficient of concluding persons’ favorites over both market and non market

Simple and fast approach is one that employs non-critical financial resolutions and in which resolutions are task-perilous or large amount of money is included in Cost-benefit Analysis(Lavee, 2010). In assessingthe public project in the city, cost benefit analysis may attain a great approval. The city has a budget to invest of in wastewater treatment. Furthermore, it enduresto face firmopposition from certain quarters for developing wastewater treatment. The application of Cost Benefit Analysis on the difficult of the socio-cultural opposition costs is to be assessed. Moreover, the faults of cost benefit analysis as a method in which the project has cash flow that may be generated in long period of time. The costs of equipment in the water treatment are also offered in the city. 

The first four steps in the U.S. Army Cost Benefit Analysis Guide as they relate to the city’s needs to increase its water treatment capacity

The first step recognizes all of the consequences or effects of a program and classifies them as benefits or costs for severalsets. Both direct and indirect effects should be analyzed. Second, dollar values are placed on various costs and benefits. This will be relatively easy for items that are customarily bought and sold in markets. For such matters as good health, the prolongation of human life, or scenic vistas, it will be much more difficult. Third, some of the consequences or effects of a policy will be current or near-term, but others will occur many years in the future, or even the next generation. Hence, proponents of cost-benefit analysis call for a discount rate to equate the value of near and long-term effects. The basic assumption underlying the discount rate is that a dollar today is worth more than a dollar years from now. Inflation may reduce the dollar’s value or purchasing power. Alternatively, the money could be invested and its value would increase. Fourth, the costs and benefits, direct and indirect, current and future, of the policy are compared. If benefits exceed costs, the policy is acceptable.

When handling wastewater, there are diverse approaches used, some exceeding others in their application. There are two extensivelyapplied approaches namely; Anaerobic and Aerobic treatment methods. The practicalfacet of the two approaches is alike, but how they treat water is slightlydistinct when it comes to electrical application and the results in the end. The main elements that distinct the two are methane gas production, energy use, and superfluous microbial cell creation. When all is said and done, cost difference in the two may ultimately $250 to $300 in a metric ton of unwanted. Nevertheless, the additional microbial cell production results in afurtherdiscardingcost and may differ from one area to another in the city. Effluent is also another factor in different areas in the city. Therefore, anaerobic method of wastewater treatment is the dominant approach in the city due to the fact that the chemical oxygen demand (COD) in the city’s wastewater is extreme; a chemical oxygen demand above 20,000 mg/L requires application of anaerobic method of wastewater treatment. Presently, parts of the city that are served by complete anaerobic treatment includealcohol refining, landfills leachate, fruit processing, paper, meat processing industry, and pharmaceuticals.

Wastewater Quantities

 The figures below show the generated amount of waste water released in 2015 in situation one isapproximately 3.3 million cubic meters, whereas the amount of wastewater released in situation two is 7 million cubic meters. Both wastewater released are treated in both the Part A of the city’s wastewater treatment process and Part B of the city’s wastewater treatment process.  Conversely, the overallamount is taken to be treated in the city for situation three. E?uent treated wastewater is considered to be 75 percent of the entireproduced amount, considering the damages in the trunk ways and damagesin the treatment process. The amount of treated wastewater likely to get to the final users is estimated at 75 percent of the e?uent quantities, consideringthe outflow and other damages in the delivery systems, it is equal to 56 percent of the wholeproduced wastewater in the city. In the dry season, the aggregateexistingquantity of the treated wastewater can be used, but in rainy seasons, there is need for only 25 percent of the amount.


Basing on the analyses above, employing either a two phase anaerobic digester or anaerobic digestercan have great importance to the city. Although the importance may be accompanied by opening charges, ultimately, the advantages doovershadow the charges as illustrated in the analysis. Wastewater costs are likely to go down to around 50 percent which the city has confirmed. Prior to employing anaerobic digester the city will pay $7/CCF contrary to merely $2.75/CCF. Employing either equipmentneeds that the city has to beproducing fairlyon large scale, this something some areas in the city need to think of as they develop.
