Waste Water Case Study

A

PROPOSED WASTE WATER

TREATMENT FACILITY

AT

BATANGAS CITY

October 4, 2015

INTRODUCTION: We populated the Earth, we explore it and we find all things we can use to survive, we gathered all the things that we can use to support our lives, the most important thing that we have is water (Water is abundant on this planet but not in forms that are always useful to humans. Of all water, 98 % is salt water, 1.6 % is ice, 0.4 % is ground water and 0.004 % is surface water. Only the latter two are important and possible as water sources for human needs, and it is clear that the resource of water is scarce) specifically the fresh water. Freshwater is the lifeblood of the Earth, all over the world

In this study, the use of wastewater for irrigation has improved the farmers’ productivity and income in terms of water saved. Another notable practice for wastewater use is the case of Absolut Distillers in Lian, Batangas wherein they are using their treated wastewater as liquid fertilizer to their sugarcane farms through fertilization truck The high organic content of the wastewater has proven to be useful in the production of sugarcane at reduced cost of fertilizer requirements with an annual savings of Php 23,272,970 or US$ 541,231.86

The Busco Sugar Milling Co., Inc. located at Brgy Butong, Quezon, Bukidnon practiced

“Zero Discharge Program” or a “Close-Loop System” through recycle and re-use. Their sugar mill employs primary and secondary treatment and its effluent is re-used in irrigating the sugarcane farm previously 95 ha but now they are irrigating about 400ha through a handmove sprinkler system. The value of average nitrogen and phosphorous content in wastewater effluent is 2.5 mg/L and 3.8 mg/L, respectively that reduces fertilizer requirements to their sugarcane farm.

BACKGROUND

d. Scope of Work

The proposed Wastewater Treatment Plant will have a treatement capacity of 1 mega-litres per day. It will serve the batangas city and nearby areas. the study is based on the earlier study. e. Socio-economic Benefits

The wastewater used for irrigation is valued by farmers, mainly because of its nutrient contents and reliability of supply and exert positive impacts on agriculture land values.

FEASIBILITY STUDY

a) Finalized detailed plan of the wastewater treatment facility considering the amount of water receive and area where the project be placed.

b) Finalized detailed plan of outsourcing the water to community considering the elevation of the area of the receiver.

c) Finalized the impact of the project to the community, economy and to the environment.

d) Prepare cost estimate for all construction.

e) Prepare a time frame for the cash flow and assessment of the project to have a smooth flow of construction and obtained the necessary goals of the project.
