CONTRACT WW 228C – Consultancy Services for the Assessment of the Port Louis Sewerage and Water Supply Systems 1.0 INTRODUCTION The Wastewater Management Authority (WMA) is the Agency designated by the Government of Mauritius for the implementation of sewerage projects under the National Sewerage Program. Following continuing problems of surcharging, blockages and the occasional collapse occurring in the ageing Port Louis Sewerage System, WMA has decided that an updated Condition Survey needs to be carried out to the total existing sewerage system of Port Louis and from this survey work establish a priority list of systems which need to be replaced / upgraded. Moreover, the survey works shall cover the CWA water supply network system. Due to the extent of the work and limitation of budget, it is planned to carry this out in 3 Phases. 2.0 PROJECT AREA The existing Port Louis sewerage system has been divided into 3 sections allowing the proposed work to be carried out in 3 Phases. Each planned phase of work covers the following districts of Port Louis:

CONTRACT WW 228C – Consultancy Services for the Assessment of the Port Louis Sewerage and Water Supply Systems – PROJECT BRIEF 1.0 INTRODUCTION 1.1 Aim of Project The Wastewater Management Authority intends to appoint an Engineering Consultancy firm, to be referred to as the “Consultant” having the necessary experience and engineering resources to cover the scope of services as detailed below under Consultancy Contract WW228C. 1.2 Project Necessity The Wastewater Management Authority (WMA), a parastatal organisation operating under the aegis of the Ministry of Energy and Public Utilities (MEPU), was established as a corporate body under the WMA Act 2000 and started operating as from 01 September 2001. The Wastewater Management Authority is the Agency designated by the Government of Mauritius for the implementation of the sewerage projects under the National Sewerage Program. Its overall objective is to contribute to the sustainable preservation of the environment and the public health. In the Port Louis area there are many sewerage lines that are over 100 years old and are in a bad stage of deterioration. Some pipes have undoubtedly cracked and some have collapsed therefore under high flow conditions frequent surcharging of the system is experienced and subsequent flooding of many housing areas experienced. By having a thorough survey carried out WMA can prioritise which sections of the sewerage system to replace first and avoid future flooding problems. There is also the need whilst the sewerage system is being surveyed and examined for the chosen consultant to carry out additional work to survey and report on the state and location of the adjoining CWA water supply systems.

1.3 Project Area The existing Port Louis sewerage and water supply systems have been divided into 3 sections allowing the proposed work to be carried out in 3 Phases. Each planned phase of work covers the following districts of Port Louis:

Phase I Phase II Phase III

2.0 SITE DESCRIPTION AND SEWERAGE PROBLEMS REPORTED Below is a brief description of problems that are being encountered at present in the Port Louis area. It is brought to the attention of all prospective bidders that the details contained therein are only indicative and non exhaustive. The main problems identified are:

Blockages and overflows are very common and are more pronounced during rainy season at certain specific areas. This problem is further aggravated by house holders dumping or flushing unsuitable material into the sewer system.

There is severe flooding of houses and yard with sewage. The existing reticulation networks have been constructed in small pipes which with time have become prone to frequent blockages and overflows.

Rain water downpipes have been routed to manholes resulting in additional pressure to the already overloaded pipes and thus causing overflows.

In times of rainfall, the sewage overflows from the manholes and contaminates river water
