--A called meeting of the Council was hold yesterday afternoon, at 4 o'clock. Present --Messrs. Saunders
, and Greanor.
, and Richardson
The President stated that the Council had been called at the request of the Watering Committee
made a motion that the Council proceed to fill the vacancy caused by the resignation of Mr. F. W. Roddey
, and the motion being carried, Robert R. Howisof
, was nominated, and unanimously elected a member from Madison Ward
stated that the Council had been called to consider the propriety of constructing a new reservoir, and briefly stated that the committee had adopted the plan prepared by Mr. W. Gill
, the City
Engineer, and Mr. Davis
, the Superintendent
of the Water Works.
From Mr. Gill
's report on the subject, we make the following extract:
"It is proposed to build the new reservoir on the east side of the present one, and to raise the water line of the present reservoir three feet higher, and to build the new reservoir to the same height.
"The new reservoir will be 500 feet long by 450 feet wide at the surface of the water, and will be divided into two equal parts by a division embankment extending through it. It will contain, when full, about thirty millions gallons of water.
The filter beds, two in number, will be located on the northern side of the new reservoir.
They will each be 246 feet long by 150 feet wide.
The filtering medium will be sand and gravel, and of sufficient capacity to filter about four and a half millions gallons of water every 24 hours.
"The capacity of the new reservoir will be about thirty millions gallons.
The present reservoir is estimated to hold about ten millions gallons more — making the storage capacity of both reservoirs about forty millions gallons — which is equal to about twenty days supply, at the present rate of consumption in the city.
Both the new and old reservoirs will be arranged by means of stop cocks and pipes that the water can be drawn at pressure from any one of the several compartments, for the purpose of cleansing or making any repairs to them.
"The very turbid character of the James river
during freshets might lead to some apprehensions with regard to clogging up, to which the filtering medium might be subject during such periods.--But when we come to consider that the water of James river
is never very turbid for more than four or five days at a time, and that there will be no difficulty in stopping the pumps at such times; and also, that the water will be some twenty days in passing through the different compartments of the reservoir, it is evident that by this arrangement the water will have ample time to deposit its sedimentary load before it reaches the filter beds.
"If, however, at any time the filtering medium should become clogged, the filtering process will be so arranged that the action of the water in passing through the filter beds can be reversed and the sedimentary deposit washed off and out of the reservoir, by means of waste pipes, which are common to the whole system.
This plan has been successfully tried by several water companies both in England
"In carrying out this plan more land will be required on the east side of the reservoir than is afforded by the recent purchase from Mr. Wooldridge
It will, therefore, become expedient to purchase the balance of the ground between the reservoir and Hollywood Cemetery.
If the reservoir is confined to the present narrow limits, it will become necessary to resort to heavy walls of masonry, with the view to economise space, which will increase the cost of the proposed reservoir fully as much as the price asked for the land.
This land will ultimately be required for reservoir purposes, and it will be economy for the city to purchase it now, with the view of the future extension of the works, and also for the purpose of keeping off from the reservoirs all objectionable encroachments.
The importance of constructing a new reservoir is evident, when we take into consideration the very limited capacity of the present one and that it is so badly arranged that it is impossible to clean out the deposit of mud which has been accumulating in it for years, without depriving the city of water.
"The following is the estimated cost of improvement: Embankment, $35,000; masonry of affluent and influent chambers, $10,000; cost of filtering arrangements, $25,000; cost of stopcocks, gates and pipes $23,000; cost of land required.
$5,000. Total $98,000.
On motion of Mr. Hill
, the report was laid on the table and ordered to be printed for the use of members.
On motion of Mr. Saunders
, the sum of $5,000 was appropriated, with which to purchase additional land for the new reservoir.
On motion, the Council adjourned.
