Background

The Municipality currently provides waste collection services to more than 59,337 residents (100% coverage) through its Department of Public Services. For collection services, the Municipality has 14 trucks in good operating condition. Trash is collected along 12 residential routes twice a week, with the exception of rural routes which are collected once a week. There is one commercial route with one truck that also provides service to the municipal parks. The remaining truck is used to collect rubbish or other waste that is reported to the Department as being in the public right-of-way.

Currently, collected solid waste is disposed of in a controlled dumpsite. However, to improve waste management and comply with Mexican federal standard NOM-083 SEMARNAT-2003, the Municipality has completed construction of a new landfill with federal funding through the Mexican Ministry of Environment and Natural Resources (SEMARNAT), as well as its own funds. The new landfill is classified as Type B (50 to 100 tons per day) and is designed to include 10 cells with an overall expected useful life of 24 years, considering the estimated generation of 55 tons of waste/day. The first cell is scheduled to be complete in June 2016. The sponsor is working with the State to close the open dumpsite, once operations begins
in the new landfill.

The Municipality currently uses a 1986 Caterpillar D7G bulldozer, which has already exceeded its expected useful life, requires constant repairs, and jeopardizes the proper management of solid waste. In addition to replacing this old vehicle, additional equipment is also required to improve soil removal operations, cover waste and reduce dust emissions during compacting activities in compliance with the applicable regulations. This equipment project complements the landfill construction project and will help ensure that it is operated properly.

Description

The proposed Project consists of the acquisition of new equipment for
landfill management and includes the following components:

• Bulldozer - Caterpillar D5 or similar, with an enclosed cabin, low
  ground pressure (LGP) tracks for added stability and greater surface
  area for more efficient waste compaction and an extended blade to
  facilitate waste dispersion and to protect the machine from waste
  passing over the top of the blade.
• Rubber tire wheel loader/backhoe - Case 580 SN or similar,
  including a hydraulically powered mechanism to scoop waste and
  other materials, an extendible dipper, and a one-cubic-yard capacity
  loader bucket with a bolt on the cutting edge.
• 3.5- or 4-ton truck, to help transport personnel and additional
  equipment in and around the landfill.
• Dump truck, with 7 cubic meter (9 cubic yard) capacity to help
  transport cover material from the stockpile or other locations to the
  landfill working front.
• Water tank truck, with 8,000-liter (2,100-gallon) capacity to control
  dust in and around the sanitary landfill, including access roads and
  cover material.
• Additional landfill equipment, including a vehicle scale, 5000-watt
  portable generator, portable welder, pressure washer, hydropneumatic water tank and a set of tools.

Benefits

Project implementation is expected to help the Municipality improve solid
waste management and disposal, as well as help reduce the possibility of
human exposure to decaying garbage, as well as eliminating the breeding
grounds for disease-carrying vectors, such as flies and mosquitos.
