Result of Physical and Chemical Analysis of Water and Wastewater PROJECT DESCRIPTION Davao City slaughterhouse is located at Ma-a, Davao City.

The operations are limited to the night shift. The delivery of animals will start at 1: 00 to 4: 30 in the afternoon. The whole morning will be utilized for cleaning the area. The 2nd shift will start at 9: 00 in the evening up to 5: 30 in the morning. It employs 48 workers of which 25 are regulars and 23 are contractual.

This contractual will do the maintenance and the manual slaughtering of animals. Currently the number of hogs, cattle's and other animals slaughtered are as follows Hogs 200 to 250 heads Cattle 30 to 40 heads Chicken none (chicken slaughterhouse is out of order) Goat 20 to 25 heads The number of heads slaughtered everyday does not level of with the number of kilos meat sold in the public market. In short there are hogs and cattle slaughtered privately. The following are the charges per head for the service rendered: Hogs P 91.11 per head Cattle P 152 per head Goat P 40.00 per head There are two stockyards presently existing in the city slaughterhouse. One is for the hogs and the other is for the large cattle. Three operational ponds are present in the slaughterhouse, the aerobic pond, anaerobic pond, and the facultative pond.

And sludge drying bed. As what we have observed there are two ways of acquiring water for use of slaughtering and maintenance of the slaughterhouse. One is the metered water system direct from the meter to the faucet and the use of water reservoir. Two large overhead tanks are place serve as water reservoir use for slaughtering and the metered water system is for office consumption. A. Basic Project Information Project Name: Davao City Slaughterhouse Address: Ma-a Davao City Contact Person: Ariel Cascabel Officer in charge The number of hogs and cattle slaughtered for the year 2004 dropped compared to past years due to the economic crisis. Ma-a slaughterhouse operation generally involves the following: a. Lairageb.

Bath. Stunning. Hoisting e. Bleeding. Scalding g. Dehairingh.

Gambrellingi. Final Scrapping. Evisceration k. Inspection. Splitting m. Weighing n.

To Offal Room. Offal Cleaning. Delivery Before the animals are slaughtered they are kept in the stockyard for 2 days and are not allowed to eat. However, they are allowed to drink water. Normally, the weight of the hogs brought range from 45 to 75 kilograms.

The average weight for cattle is 300 kilograms. Slaughtering starts with bringing the animals from a narrow path way from the stockyard to the kill floor area. Then proceed to showering / bathing. Afterwards, the animals are stunned, hoist and bleed. Blood pails are provided with control numbers. Blood containment shall depend on the desire of the owners of the animals.

The animals are then placed in a scalding vat for 3 minutes. If the animals are oversized, the Dehai ring machine shall not be used. A table for manual scrapping is provided. After the scrapping and process follows the gambrel ling process, toe removal, and final scrapping, then the evisceration process. The butcher carefully removes the viscera or entrails while preventing accidental puncture or the intestinal tract. The eviscerated carcass and entrails are cleaned separately to prevent contamination of the carcass.

The meats are then inspected by the National meat Inspector Commission and seal it certifying its approval. The animals are then split and weighed and shall be brought to the offal room. The offal's shall be carried (hand) through the maintenance of the Offal Manager to the Offal cleaning table. Guided by the board tally, the Offal manager shall assign particular offal to particular table. The cleaned shall be placed in a pre-numbered pan. The pan to be used for particular offal shall bear the number of animals.

And lastly, is the delivery of the animals. The operation in Ma-a slaughterhouse generates wastes of different types: A. SOLID WASTESo Intestine so Gallbladder so Horn so Manure o Hair and bristle so Meat trimming so Rejected carcasses o Other organs. LIQUID WASTESo Urine Blood Wash water. GASEOUS WASTESo Odor Condensates The Ma-a slaughterhouse has three ponds, the aerobic pond, anaerobic pond, and the facultative pond, which are used for the wastewater. There is also a sludge drying bed for the sludge.

The solid wastes generated are just disposed in a nearby dumpsite or within the area, which then creates foul odor. Some solid wastes like bones and coagulated bloods are sold as fertilizers. Uncollected bloods are directly thrown to floor drains. B. Project Location Davao City slaughterhouse is located at Ma-a Davao City. The industry is isolated into the community of Ma-a District and has a fence all over the area. It occupies about 10,000 sq. meters of land and is isolated with the residential areas. It drains its waste through the waste water system of Davao City.

That's why a minimal area is only affected with its operation. C. Project Rationale Slaughterhouse obtains highest degree of efficiency when run by highly trained individuals. Davao City slaughterhouse is obviously not managed efficiently and professionally. Employee's with only 50 people to operate a big size slaughterhouse are not healthy. This report will attempt to dissect whether the investment for the operation of the Davao City slaughterhouse is well managed and operating under a healthy cash flow. Slaughterhouse is a very critical economic enterprise where safety of the consuming public is of the highest priority including the families living within the facility necessarily. The different activities involved require precision.

On the other hand, operating cost should be kept at desirable levels to maintain the slaughtering viability. Slaughterhouse whether regional or municipal requires huge capital investment, its efficiency is dependent on the amount of time spend on training the staff handling both management and operation. Since it is equipment intensive, use of these resources is of highest consideration. The slaughterhouse subject of this report is of old type upgraded to meet current demand. The following report will attempt to determine whether the introduction or new to improve production is a viable venture. D. Alternative Different kind of waste generated in the slaughterhouse.

They have adapted several waste reduction measures to minimize generations of these wastes in the slaughterhouse. The solid waste like bones and coagulated bloods are sold as fertilizer. Other is just disposed in a nearby dumpsite or within the area, which then creates foul odor. These actions reduced the wastes for disposal and creating revenue for the firm. The following are the alternative waste minimization options for Davao City slaughterhouse illustrating payback period for each. Low Cost Minimization Option Recycling Water for Reuse / Installation of water tank and pipeline Its installation will reduce water consumption and wastewater generation.

An estimated 50% of the daily water usage will be recycled if such option will be implemented. Blow down water from the boiler, which amounts to an average 0.60 m 3/day, laboratory water amounting to about 0.69 m 3/day, and cleaning water estimated at 9 m 3/day (0.50 x 18 m 3/day) would produce a total of 10.29 m 3/day of recycle water.

Providing such device could efficiently recover more blood to prevent blood spillage in the slaughtering area, thereby reducing the BOD load to WTP, and improving environmental compliance. Slaughterhouse north generates 853 mg / L BOD. Capital cost of this option is for the purchase of blood suction device at P 55,000.00.

Revenue generation is from blood recovery, which can be sold at P 1.00/kg. The facility slaughters 310 Cattle / mo in just 14 days operation.

P 55,000.00 Available locally The best among the three options is the regular scrubbing of boiler chimney. Since capital cost is not necessary. The slaughterhouse will just enjoy the saving amounting to P 35,224.

Thus, implementing this option would reduce flue gas particulate emission with a corresponding reduction in boiler fuel consumption of 10%. Implementing this kind of option, particulate emissions would be reduced, and the regulatory compliance of the facility would improve. E. Description of Project Phases I. Pre Construction / Operational Phase Davao City slaughterhouse was constructed in an already isolated and open space areas therefore there are no residential areas affected or being displaced from the project site. But other risk wouldn't be avoided such as the noise that such activity would bring. Workers exposed to safety hazards of construction and as well as soil erosion. II. Construction Phase Noise still remains to be a problem in this phase.

Files of cements as well as sand and gravels being brought to construction site can then create dust that can harm the workers. Thus, excessive use of vehicles and heavy equipments are present through out the project. Air pollution is also feasible with this phase. Cement particulates and dust fly freely everywhere. These pollutants can be inhaled not only by the workers but also the immediate residents nearby.. Operational Phase Water pollution is observed during this phase.

It generates different types of waste such as Solid, Liquid and Gaseous Waste. This waste creates foul odor. Health hazards are greatly the most significant area of impact of recognition, because the butcher is the most expose on the operation. IV. Abandonment Aesthetic impact brought about by the presence of the project is one of the positive impacts. Currently Ma-a slaughterhouse employs 48 workers of which 25 are regulars and 23 are contractual.

It is now providing meats of hots and cattle's that are sold in the market of Bankerohan, Ag dao, Malls of NCC C, Gai sano, and SM. In which the people of this area are purchasing for food consumption and survival. F. Baseline Environment Flat or level The area is not erosion prone or a flood prone / storm surge area. There are no existing natural hazards in the area such as landslides and gull ying. It is not beside or near a shoreline. Air The quality of air in the area is good for it has been miles away from the center of the city in which pollution is rampant. Water Water in the area is fresh.

There is a water body found near in the project site, which is the Davao River. People There are no existing settlements in the proposed slaughterhouse that would be displaced because the area is far from the residential site. G. Impact Assessment and Mitigation. impact Identification COMPONENTS / PARAMETERS IMPACTS MITIGATING MEASURE 1. Land Clearing Change in landforms. Identify the exact scale of land to be cleared 2.

Tree Cutting Modification of landforms. Identify the exact number of trees to be cut. 3. Excavation works cut and fill activities Soil erosion. Avoid excavating and filling into those critical areas. 4.

Stock piling of sand gravel material Generates noise as well as in gas level. Pile the raw materials away from the community to avoid noise and dust. 5. Availability of employment Migration of workers Identify the exact number of workers. II. Impact Prediction COMPONENTS / PARAMETERS IMPACTS MITIGATING MEASURE 1.

Project will generate wastewater. Generates foul smell. Contamination would cause health problem. Sedimentation, Coagulation and Flocculation, reverse osmosis. 2. Increase in water demand.

Change in hydrology. Use water reservoir for Slaughtering process. 3. Affect the ambient air quality of the area. Increase Dust Dry Control Methods 4. Generation of solid waste.

Increase health problems due to foul odor. Evaporation, Burial, Biological treatment.. Future Environmental conditions with out the project The area would be a residential area. Like subdivisions, village, or a Relocation Area, for the reason that Davao City nowadays continue to grow in terms of all aspects. Thus, economic and extensive land use of the people as well as the emerging industries.

IV. Future Environmental Conditions with the Project If Davao City slaughterhouse continues its operation for the next ten years there would be an increase of wastewater generation in the project, quality of the receiving water body of water will be affected more than its previous operation, quality of air in the area will be affected due to the foul odor generated in the slaughtering process, generation of solid waste will be doubled, complaints from the nearby residents. But there is still an aesthetic effect of the project, which is the increase in the availability of employment that people needs nowadays. H. Environmental Management PlanI. Mitigation / Enhancement Measures / Plan (impact / risk ) o Comply with existing environmental rules and regulations guidelines and criteria required by the DENR. o Comply with all mitigation and enhancement measures that have been identified. o Construct, Operate, and maintain well-design sewage and drainage facilities. II. Environmental Monitoring Action Plano Observe proper waste management practices by providing adequate garbage receptacles in strategic points of the project site and observing regular garbage collection and disposal in an approval disposal site..

Institutional Plano Establish adequate open spaces within the project site for loading / unloading purposes and the provisions of access road. IV. Information, Education, Communication Plano Organize and conduct information, education and communication (IEC) activities on integrated Solid Waste Management Program such as recycling, Re-use, composting, sanitation, proper collection and disposal of solid. o Properly brief or orient the Project Administrator and beneficiaries about the EEC conditions, commitment and agreements made about the project. o Support continuing government efforts to promote environmental sound Slaughter House project. I. Proposal for an Environmental Monitoring and Guarantee FundA slaughterhouse of this size requires regular environmental monitoring. To do this, it has to undergo environmental impact assessment to determine whether there is violation of the mitigating measures. To achieve this, a respectable budget should be included in the maintenance and operating cost to answer for many defects that may result to environmental disaster, this budget should be on regular basis to include hiring in contractual basis environmental engineer.
