Tender Details

Tenders are invited for Consultancy for Hydrogeological Study for the Erigavo Aquifer, Sanaag Region, Somaliland.

1. BACKGROUND INFORMATION
? About Norwegian Refugee Council and the Project
Norwegian Refugee Council (NRC) has been present in Somaliland since early
2006. Over these years, the Norwegian Refugee Council (NRC) has demonstrated
a regional competence and expertise in working with displaced populations with
programs in Food Security, Education, Water and Sanitation, Shelter, Information
Counselling and Legal Assistance. Since 2013 NRC has become one of the leading
actors in Implementing resilience programs in Somalia.
In Sanaag Region, NRC is implementing a resilience programme funded by DFIDUK through the Building Resilient Communities in Somalia (BRCiSII)
consortium. The resilience program is intended to contribute to resilience of the
target communities to shocks of drought, flood, conflict and diseases.

As part of the resilience program in Somaliland, NRC intends to support the
communities of Seeraha Village, Erivago District, Sanaag Region through
establishment of sustainable water supply Systems for Productive (Irrigation) and
domestic use. NRC has drilled a borehole in Seeraha at a depth of 125m. The
borehole has penetrated a confined aquifer thus releasing pressure and raising the
water level above the ground level (Artesian well). A simple test using a calibrated
container indicates a free flow of 18m3/hr.
NRC is seeking the service of a qualified and well-experienced hydrogeologist(s)
to undertake a study of the hydrogeology of the aquifer thus determine its
parameters and recommend a safe and sustainable abstraction regime.
1.2 Purpose of the consultancy
The main objective of the consultancy is to undertake a detailed hydrogeological
study of the underlying aquifer in Erigavo town and mainly around the Seeraha
Village. The location of the study is within coordinates Latitude 10.62.72 and
longitude 47.36.87 The study shall define the Aquifer characteristics, that is:
? The hydraulic conductivity (K),
? The aquifer transmissibility (T),
? The storage coefficient (S),
? The yield of the aquifer,
? The thickness of the saturated zone,
? The position of the hydraulic headin the aquifer,

2.0 SCOPE OF WORK & METHODOLOGY
The consultant will work closely with Ministry of Water (Somaliland), office of
the governor of Sanaag, office of the mayor Erigavo the community leaders and
members and NRC Staff. It is expected that the consultant will:
? (i) Review the existing literature on the general Hydrogeology of Sannag
Region and in particular Erigavo District. Secondary data will involve desk
study of available information from SWALIM, existing studies, existing
boreholes, topographical maps, satellite images, borehole site investigations
in the area, geological reports and maps, etc
? (ii) Primary data will be obtained by carrying out pumping test
measurements for the newly drilled Seeraha Borehole using the necessary
equipment including and analysing the data using appropriate groundwater
modelling software. This shall involve water level measurements, inspection
of geological log, verification of existing data and details of existing water
sources in the study area.
? (iii) Determine the Aquifer characteristics including the: hydraulic
conductivity (K), aquifer transmissibility (T), storage coefficient (S), yield
of the aquifer, thickness of the saturated zone, position of the hydraulic
head in the aquifer.
? (iv) Undertake the assessment of holistic water needs for the target primary
and secondary villages within the study area and recommend design/service
parameters that he/she considers appropriate for safe but sufficient water
supply for irrigation and domestic use in the study area.
? (v) Design and recommend the technology and equipment specification
most appropriate for groundwater abstraction (solar technology is preferred)
to meet the local needs and monitoring to ensure sustainability.
? (vi) Recommend appropriate measures for operation and maintenance of the
pumping equipment and entire water supply system,
? (vii) Undertake an Environmental Impact Assessment and recommend
mitigation measures to minimize any negative effects of ground water
abstraction.
? Present the findings of the study and various recommendations to the Ministry of Water, Local authorities within Erigavo, community leaders and NRC staff

All Applications should be submitted from 21st to 31st 2019 at 4:00pm and to be
sent to the this email: so.procurement@nrc.no and all queries to be addressed
to this email: mercy.gitau@nrc.no
