Rural Water Monitoring Project
Background
Rural Ireland is served mainly by grant-aided group water schemes, which have been successful in bringing water supplies to areas not served by the public mains. The water they provide is generally untreated and many supplies are unfit for human consumption.
The Rural Water Monitoring was set up by the DOELG in response to the poor quality of rural water supplies. Its objectives are to examine the quality of water supplied by all group water schemes in County Roscommon, to identify the factors adversely affecting water quality and to investigate measures for improvement. The project is 100% funded by the DOELG and was approved by the Minister in February 1999.
Roscommon County Council was chosen for the project because the county has a manageable number of schemes all within reach, and diverse enough in terms of source and size to be representative of group water schemes in the county as a whole.
The project is overseen by a Steering Committee comprising of representatives from Roscommon County Council, the National Federation of Group Water Schemes and Dublin Corporation. Dublin Corporation was included because it had the laboratory facilities and technical expertise to get the project up and running.
Sampling points were chosen so that they provide the most representative samples of the schemes. In general, the source, a mid-way sampling point and a point at/near the end of the distribution main were used. If a scheme serves less than 15 houses, only two sampling points were selected.
The interim report "Roscommon County Council Rural Water Monitoring Project", published in 2000 gives a mid-way assessment of the water quality in group water schemes. The report covered the period from March 1999 to March 2000 inclusive. The assessment revealed that many schemes were supplying drinking water of a much lower standard than that specified in European Communities (Quality of Water Intended for Human Consumption) Regulations, 1988.
For presumptive total coliforms it was found that only 2 out of a total of 65 sources consistently had zero presumptive total coliforms thus indicating that all except 2 sources require disinfection.
For presumptive faecal coliforms, it was found that 58% of samples taken from private schemes and 4% of samples from semi-private schemes tested positive.
Excessive levels of colour were observed for 22 out of a total of 61 sources over the study period. Out of a total of 64 sources, 24 exceeded the limit for turbidity, at least once during the study period. High turbidity in water can also cause problems in water treatment, by making disinfection difficult.
Iron, manganese and to a lesser extent aluminium were also present in excessive levels in some waters-18.2% of source samples exceeded the national limit for iron, 21.1% of source samples exceeded the national limit for manganese and 7.7% exceeded the national limit for aluminium.
Results for pH in all, except 3 samples, were within the required range for pH in potable waters and was not a cause for concern.
During the study period 4 samples from 3 different sources exceeded the national limit for nitrite-a possible indication that water is organically polluted. It was found that 6 private sources, all ground waters, exceeded the national limit value for ammonia-indicating a nearby source of organic pollution. Results for nitrate, phosphorus, and heavy metals were not a cause for concern. 41% of private scheme samples and 3% of semi-private samples had no chlorine residual.
Actions taken to improve water quality:
As a result of the high level of bacterial contamination of so many group water schemes, the Steering Committee took the decision early on, that the situation merited urgent action. Measures to improve water quality, decided on at the outset of the study were brought forward.
- Two pilot treatment plants to be installed - Pollcat Springs and Cavetown Lake
- Training to be provided for groups operating schemes
- A range of "point of use" i.e. one-house treatment systems to be pilot tested
- Roscommon County Council to arrange, on behalf of 21 schemes, for installation of chlorination units
Current status of the proposed actions:
A training seminar has been provided for the operators of schemes. Plans are going ahead for the installation of the two pilot treatment plants and chlorination units. Some chlorination plants have already been installed but none are operational. No improvement in water quality can be expected until this happens.
The pilot testing on the one-house treatment systems spanned 12 months beginning in March 2000. The final analysis of results has not been done yet but indications so far are that results have been quite inconsistent. Suppliers of the treatment systems agreed at the outset of pilot testing to maintain the units for one year, but many failed to do so. It will be difficult to assess the efficiency of the systems that have not been properly maintained.
Because it has the facilities and technicial expertise, Roscommon County Council's Laboratory has tendered for the sampling of group water schemes in other counties. It is currently contracted by the consultant for the DOELG to sample group water schemes on Counties Offaly, Longford, Leitrim and Sligo on a monthly basis.

Responsibility for Group water schemes was devolved from the Department of Environment and Local Government to the local authority in 1997. In 2010 the following works were carried out by Roscommon County Council under the programme:
Design Build Operate Project for Water Treatment:
The priority of the Rural Water Programme is to facilitate the upgrading of water quality in the private group scheme sector. Twenty-two schemes are included in the DBO project for the county that will see the construction of six new water treatment plants. Twenty schemes have amalgamated into three new cooperative group water schemes - Mid Roscommon GWS, Oran Ballintober GWS and Curracreigh GWS. The DBO Contract for the treatment plants hadvertised in 2008 a contract signed with Glan Agua Ltd., Ballinasloe Co. Galway in January 2010 for the construction of seven water treatment plants (including one in Co Leitrim). Four contracts for advance/enabling works on the new schemes and the Knockcroghery Lecarrow Public Scheme (included in the DBO contract) were completed in 2010. The total value of the advance contracts is €10.8 million. The project is co funded by the EU under the European Regonal Development Fund and the Irish Government under under Irelands EU Structural Funds Programmes 2007-2013 www.bmwassembly.ie
Small Schemes Programme:
The Council received an allocation of €450,000 from the Department of Environment, Heritage and Local Government to upgrade public water and sewerage schemes in 2010, representing a contribution of 75% of the cost. A total of €248,886.33 was expended on completing all outstanding schemes and commencing works on the 2010 schemes. All five schemes under the 2010 programme commenced and will be completed in 2011.
Take in Charge and Connection to the Public Main:
The Tartan Scurmore private group water scheme was connected to the Grangemore public supply in 2010.
New Group Schemes:
There were no new semi private group schemes constructed in 2010.
Water & Sewer Connections:
During 2010 a total of 74 licences were issued for 79 connections to the public water mains, public sewerage, and group water schemes. There were 22 connections to the public mains including 4 additional agricultural connections, 8 connections to the public sewerage network and also 49 licences issued for road openings based on connection fees paid through the development contribution scheme.
Individual Water Supply Grants:
Houses that are not either connected to the public mains or a private water scheme may be eligible for a grant to upgrade their supply if their house is more than seven years old. The grant amounts to 75% of the cost subject to a maximum payment of €2,031.58. A total of €13,338.48 was paid in grants in 2010 to seven approved applicants.
Subsidy towards the Operational Cost of Group Water Supply Schemes:
Subsidies are payable to group water schemes to help offset costs incurred in the day to day provision of a water supply to domestic houses. A total of €317,640.46 was paid to sixteen group schemes in 2010 in respect of claims made during the year. The subsidy is recouped in full from the Department.
